  • BOXED WARNING (What is this?)

    WARNING: CIGARETTE SMOKING AND SERIOUS CARDIOVASCULAR EVENTS

    Cigarette smoking increases the risk of serious cardiovascular events from combination oral contraceptive (COC) use. This risk increases with age, particularly in women over 35 years of age, and with the number of cigarettes smoked. For this reason, COCs should not be used by women who are over 35 years of age and smoke [see Contraindications (4) and Warnings & Precautions (5.1)].

  • 1 INDICATIONS & USAGE

    MERZEE is indicated for use by females of reproductive age to prevent pregnancy [see Clinical Studies (14)].

    The efficacy of MERZEE in women with a body mass index (BMI) of more than 35 kg/m2 has not been evaluated.

  • 2 DOSAGE & ADMINISTRATION

    2.1 How to Take MERZEE

    To achieve maximum contraceptive effectiveness, MERZEE must be taken exactly as directed. Instruct patients to take one capsule by mouth at the same time every day. Capsules must be taken in the order directed on the blister pack. Capsules should not be skipped or taken at intervals exceeding 24 hours. MERZEE may be administered without regard to meals [see Clinical Pharmacology (12.3)].

    2.2 How to Start MERZEE

    Instruct the patient to begin taking MERZEE either on the first day of her menstrual period (Day 1 Start) or on the first Sunday after the onset of her menstrual period (Sunday Start).

    Day 1 Start
    During the first cycle of MERZEE use, instruct the patient to take one pink capsule daily, beginning on Day one (1) of her menstrual cycle (the first day of menstruation is Day one). She should take one pink capsule daily for 24 consecutive days, followed by one maroon capsule daily on days 25 through 28. MERZEE should be taken in the order directed on the package at the same time each day. Instruct the patient to use a non-hormonal contraceptive as back-up during the first 7 days if she starts taking MERZEE on a day other than the first day of her menstrual cycle. The possibility of ovulation and conception prior to initiation of medication should be considered.

    Sunday Start
    During the first cycle of MERZEE use, instruct the patient to take one pink capsule daily, beginning on the first Sunday after the onset of her menstrual period. She should take one pink capsules capsule daily for 24 consecutive days, followed by one maroon capsule daily on days 25 through 28. MERZEE should be taken in the order directed on the package at the same time each day. MERZEE should not be considered effective as a contraceptive until after the first 7 consecutive days of product administration. Instruct the patient to use a non-hormonal contraceptive as back-up during the first 7 days. The possibility of ovulation and conception prior to initiation of medication should be considered.

    The patient should begin her next and all subsequent 28-day regimens of MERZEE on the same day of the week that she began her first regimen, following the same schedule. She should begin taking her pink capsules on the next day after ingestion of the last maroon capsule, regardless of whether or not a menstrual period has occurred or is still in progress. Anytime a subsequent cycle of MERZEE is started later than the day following administration of the last maroon capsule, the patient should use another method of contraception until she has taken a pink capsule daily for 7 consecutive days.

    For postpartum women who do not breastfeed or after a second trimester abortion, start MERZEE no earlier than 4 weeks postpartum due to the increased risk of thromboembolism. If the patient starts MERZEE postpartum and has not yet had a period, evaluate for possible pregnancy, and instruct her to use an additional method of contraception until she has taken MERZEE for 7 consecutive days.

    MERZEE may be initiated immediately after a first-trimester abortion or miscarriage; if the patient starts MERZEE immediately, additional contraceptive measures are not needed.


    Switching from another Hormonal Method of Contraception

    If the patient is switching from a combination hormonal method such as:
    Another pill
    Vaginal ring
    Patch

    Instruct her to take the first pink capsule on the day she would have taken her next COC pill. She should not continue taking the tablet from her previous birth control pack, and should not skip any days between packs. If she does not have a withdrawal bleed, rule out pregnancy before starting MERZEE.
    If she previously used a vaginal ring or transdermal patch, she should start using MERZEE on the day she would have resumed the previous product.

    If the patient is switching from a progestin-only method such as a:
    Progestin-only pill
    Implant
    Intrauterine system
    Injection

    She may switch any day from a progestin-only pill; instruct her to take the first pink capsule on the day she would have taken her next progestin-only pill. She should use a non-hormonal method of contraception for 7 consecutive days.
    If switching from an implant or injection, start the first pink capsule on the day her next injection would have been due or on the day of removal of her implant.
    If switching from an IUD, depending on the timing of removal, back-up contraception may be needed.

    2.3 Missed Doses

    Table 1. Instructions for Missed MERZEE Capsules

    If one pink capsule is missed

    If three or more pink capsules in a row are missed
     
    		Day 1 Starter:
    Throw out the rest of the MERZEE pack and start a new pack that same day.
     
    Sunday Starter:
    Keep taking one capsule every day until Sunday. On Sunday, throw out the rest of the pack and start a new pack of capsules that same day.
     
    Bleeding may occur during the week following the missed capsules.
    Use additional nonhormonal contraception (such as condoms) until hormonal capsules have been taken for 7 days after missing capsules.
    If any of the four maroon capsules are missed
    		Throw away the missed capsules. Continue taking the remaining capsules until the pack is finished.
    Additional nonhormonal contraception (such as condoms) is not needed.

    2.4 Advice in Case of Gastrointestinal Disturbances

    If the patient vomits or has diarrhea (within 3 to 4 hours after she takes a pink capsule), she should follow the instructions in the “What to Do if You Miss Capsules” section [see Dosage and Administration (2.3)].

  • 3 DOSAGE FORMS & STRENGTHS

    MERZEE is available in blister packs.

    Each blister pack contains 28 soft gelatin capsules in the following order:
     24 oval, opaque, pale pink (active) soft gelatin capsule with ‘SP’ printed on the outer shell in black and each containing 1 mg norethindrone acetate and 20 mcg ethinyl estradiol.
     4 oval, opaque, maroon, (non-hormonal placebo) capsules imprinted with “SP” on one side and each containing 75 mg ferrous fumarate. The ferrous fumarate capsules do not serve any therapeutic purpose.

  • 4 CONTRAINDICATIONS

    MERZEE is contraindicated in females who are known to have or develop the following conditions:
     A high risk of arterial or venous thrombotic diseases. Examples include women who are known to:
     Smoke, if over age 35 [see Boxed Warning and Warnings and Precautions (5.1)]
     Have deep vein thrombosis or pulmonary embolism, now or in the past [see Warnings and Precautions (5.1)]
     Have cerebrovascular disease [see Warnings and Precautions (5.1)]
     Have coronary artery disease [see Warnings and Precautions (5.1)]
     Have thrombogenic valvular or thrombogenic rhythm diseases of the heart (for example, subacute bacterial endocarditis with valvular disease, or atrial fibrillation) [see Warnings and Precautions (5.1)]
     Have inherited or acquired hypercoagulopathies [see Warnings and Precautions (5.1)]
     Have uncontrolled hypertension [see Warnings and Precautions (5.4)]
     Have diabetes mellitus with vascular disease [see Warnings and Precautions (5.6)]
     Have headaches with focal neurological symptoms or have migraine headaches with aura
       o Women over age 35 with any migraine headaches [see Warnings and Precautions (5.7)]
     Liver tumors, benign or malignant, or liver disease [see Warnings and Precautions (5.2)]
     Undiagnosed abnormal uterine bleeding [see Warnings and Precautions (5.8)]
    Current diagnosis of, or history of, breast cancer, which may be hormone-sensitive [see Warnings and Precautions (5.11)]
     Use of Hepatitis C drug combinations containing ombitasvir/paritaprevir/ritonavir, with or without dasabuvir, due to the potential for ALT elevations [see Warnings and Precautions (5.3)]

  • 5 WARNINGS AND PRECAUTIONS

    5.1 Thromboembolic Disorders and Other Vascular Problems

    Stop MERZEE if an arterial or deep venous thrombotic event (VTE) occurs. Stop MERZEE if there is unexplained loss of vision, proptosis, diplopia, papilledema, or retinal vascular lesions. Evaluate for retinal vein thrombosis immediately.

    If feasible, stop MERZEE at least 4 weeks before and through 2 weeks after major surgery or other surgeries known to have an elevated risk of VTE.

    Start MERZEE no earlier than 4 weeks after delivery, in women who are not breastfeeding. The risk of postpartum VTE decreases after the third postpartum week, whereas the risk of ovulation increases after the third postpartum week.

    The use of COCs increases the risk of VTE. However, pregnancy increases the risk of VTE as much or more than the use of COCs. The risk of VTE in women using COCs is 3 to 9 per 10,000 woman-years. The risk of VTE is highest during the first year of use of a COC. The risk of thromboembolic disease due to oral contraceptives gradually disappears after COC use is discontinued.

    Use of COCs also increases the risk of arterial thromboses such as strokes and myocardial infarctions, especially in women with other risk factors for these events. COCs have been shown to increase both the relative and attributable risks of cerebrovascular events (thrombotic and hemorrhagic strokes), although, in general, the risk is greatest in older (> 35 years of age), hypertensive women who also smoke. COCs also increase the risk for stroke in women with underlying risk factors.

    Use COCs with caution in women with cardiovascular disease risk factors.

    5.2 Liver Disease

    Impaired Liver Function
    Do not use MERZEE in women with acute viral hepatitis or severe (decompensated) cirrhosis of liver [see Contraindications (4)]. Acute or chronic disturbances of liver function may necessitate the discontinuation of COC use until markers of liver function return to normal and COC causation has been excluded. Discontinue MERZEE if jaundice develops.

    Liver Tumors

    MERZEE is contraindicated in women with benign and malignant liver tumors [seeContraindications (4)]. Hepatic adenomas are associated with COC use. An estimate of the attributable risk is 3.3 cases per 100,000 COC users. Rupture of hepatic adenomas may cause death through intra- abdominal hemorrhage.

    Studies have shown an increased risk of developing hepatocellular carcinoma in long-term (>8 years) COC users. However, the attributable risk of liver cancers in COC users is less than one case per million users.

    5.3 Risk of Liver Enzyme Elevations with Concomitant Hepatitis C Treatment

    During clinical trials with the Hepatitis C combination drug regimen that contains ombitasvir/paritaprevir/ritonavir, with or without dasabuvir, ALT elevations greater than 5 times the upper limit of normal (ULN), including some cases greater than 20 times the ULN, were significantly more frequent in women using ethinyl estradiol-containing medications, such as COCs. Discontinue MERZEE prior to starting therapy with the combination drug regimen ombitasvir/paritaprevir/ritonavir, with or without dasabuvir [see Contraindications (4)]. MERZEE can be restarted approximately 2 weeks following completion of treatment with the Hepatitis C combination drug regimen.

    5.4 High Blood Pressure

    MERZEE is contraindicated in women with uncontrolled hypertension or hypertension with vascular disease [see Contraindications (4)]. For women with well-controlled hypertension, monitor blood pressure and stop MERZEE if blood pressure rises significantly.

    An increase in blood pressure has been reported in women taking COCs, and this increase is more likely in older women with extended duration of use. The incidence of hypertension increases with increasing concentrations of progestin.

    5.5 Gallbladder Disease

    Studies suggest a small increased relative risk of developing gallbladder disease among COC users. Use of COCs may also worsen existing gallbladder disease.
    A past history of COC-related cholestasis predicts an increased risk with subsequent COC use. Women with a history of pregnancy-related cholestasis may be at an increased risk for COC-related cholestasis.

    5.6 Carbohydrate and Lipid Metabolic Effects

    Carefully monitor prediabetic and diabetic women who are taking MERZEE. COCs may decrease glucose tolerance in a dose-related fashion.

    Consider alternative contraception for women with uncontrolled dyslipidemias. A small proportion of women will have adverse lipid changes while on COCs.

    Women with hypertriglyceridemia, or a family history thereof, may be at an increased risk of pancreatitis when using COCs.

    5.7 Headache

    If a woman taking MERZEE develops new headaches that are recurrent, persistent, or severe, evaluate the cause and discontinue MERZEE if indicated.

    Consider discontinuation of MERZEE in the case of increased frequency or severity of migraine during COC use (which may be prodromal of a cerebrovascular event) [see Contraindications (4)].

    5.8 Bleeding Irregularities and Amenorrhea

    Unscheduled Bleeding and Spotting
    Unscheduled (breakthrough or intracyclic) bleeding and spotting sometimes occur in patients on COCs, especially during the first three months of use. If bleeding persists or occurs after previously regular cycles, check for causes such as pregnancy or malignancy. If pathology and pregnancy are excluded, bleeding irregularities may resolve over time or with a change to a different COC.

    Based on patient diaries from a clinical trial evaluating the safety and efficacy of a 24-day regimen of norethindrone acetate 1 mg/ethinyl estradiol 0.020 mg tablets, 24-35% of women experienced unscheduled bleeding per cycle. A total of 10 subjects out of 743 (1.3%) discontinued due to bleeding or spotting.

    Amenorrhea and Oligomenorrhea
    Women who are not pregnant and use MERZEE may experience amenorrhea. In the clinical trial with a 24-day regimen of norethindrone acetate 1 mg/ethinyl estradiol 0.020 mg tablets, 22 to 36% of the women using norethindrone acetate 1 mg/ethinyl estradiol 0.020 mg tablets experienced amenorrhea in at least one of 6 cycles of use. Some women may experience post-pill amenorrhea or oligomenorrhea, especially when such a condition was preexistent.

    If scheduled (withdrawal) bleeding does not occur, consider the possibility of pregnancy. If the patient has not adhered to the prescribed dosing schedule (missed one or more active capsules or started taking them on a day later than she should have), consider the possibility of pregnancy at the time of the first missed period and take appropriate diagnostic measures. If the patient has adhered to the prescribed regimen and misses two consecutive periods, rule out pregnancy.

    5.9 COC Use before or during Early Pregnancy

    Extensive epidemiologic studies have revealed no increased risk of birth defects in women who have used oral contraceptives prior to pregnancy. Studies also do not suggest a teratogenic effect, particularly in so far as cardiac anomalies and limb reduction defects are concerned, when oral contraceptives are taken inadvertently during early pregnancy. Discontinue MERZEE if pregnancy is confirmed.

    Administration of oral contraceptives to induce withdrawal bleeding should not be used as a test for pregnancy [see Use in Specific Populations (8.1)].

    5.10 Depression

    Carefully observe women with a history of depression and discontinue MERZEE if depression recurs to a serious degree.

    5.11 Malignant Neoplasms

    Breast Cancer
    MERZEE is contraindicated in females who currently have or have had breast cancer because breast cancer may be hormonally sensitive [see Contraindications (4)].

    Epidemiology studies have not found a consistent association between use of combined oral contraceptives (COCs) and breast cancer risk. Studies do not show an association between ever (current or past) use of COCs and risk of breast cancer. However, some studies report a small increase in the risk of breast cancer among current or recent users (<6 months since last use) and current users with longer duration of COC use [see Adverse Reactions (6.2)].

    Cervical Cancer

    Some studies suggest that COCs are associated with an increase in the risk of cervical cancer or intraepithelial neoplasia. However, there is controversy about the extent to which these findings may be due to differences in sexual behavior and other factors.

    5.12 Effect on Binding Globulins

    The estrogen component of COCs may raise the serum concentrations of thyroxine-binding globulin, sex hormone-binding globulin and cortisol-binding globulin. The dose of replacement thyroid hormone or cortisol therapy may need to be increased.

    5.13 Monitoring

    A woman who is taking COCs should have a yearly visit with her healthcare provider for a blood pressure check and for other indicated healthcare.

    5.14 Hereditary Angioedema

    In women with hereditary angioedema, exogenous estrogens may induce or exacerbate symptoms of angioedema.

    5.15 Chloasma

    Chloasma may occasionally occur, especially in women with a history of chloasma gravidarum. Women with a tendency to chloasma should avoid exposure to the sun or ultraviolet radiation while taking MERZEE.

  • 6 ADVERSE REACTIONS

    The following serious adverse reactions with the use of COCs are discussed elsewhere in the labeling:
     Serious cardiovascular events and stroke [see Boxed Warning and Warnings and Precautions (5.1)]
     Vascular events [see Warnings and Precautions (5.1)]
     Liver disease [see Warnings and Precautions (5.2)]

    Adverse reactions commonly reported by COC users are:
     Irregular uterine bleeding
     Nausea
     Breast tenderness
     Headache

    6.1 Clinical Trial Experience

    Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to the rates in the clinical trials of another drug and may not reflect the rates observed in practice. The data presented in Section 6.1 are from a clinical trial conducted with a 24-day regimen of norethindrone acetate 1 mg/ethinyl estradiol 0.020 mg tablets. MERZEE capsules are  bioequivalent to these norethindrone acetate/ethinyl estradiol tablets.

    Common Adverse Reactions (≥ 2% of all Treated Subjects): The most common adverse reactions reported by at least 2% of the 743 women using norethindrone acetate/ethinyl estradiol tablets were the following, in order of decreasing incidence: headache (6.3%), vaginal candidiasis (6.1%), nausea (4.6%), menstrual cramps (4.4%), breast tenderness (3.4%), bacterial vaginitis (3.1%), abnormal cervical smear (3.1%), acne (2.7%), mood swings (2.2%), and weight gain (2.0%).
    Adverse Reactions Leading to Study Discontinuation: Among the 743 women using norethindrone acetate/ethinyl estradiol tablets, 46 women (6.2%) withdrew because of an adverse event. Adverse events occurring in 3 or more subjects leading to discontinuation of treatment were, in decreasing order: abnormal or irregular bleeding (1.3%), nausea (0.8%), menstrual cramps (0.5%), and increased blood pressure (0.4%).

    6.2 Postmarketing Experience

    Five studies that compared breast cancer risk between ever-users (current or past use) of COCs and never-users of COCs reported no association between ever use of COCs and breast cancer risk, with effect estimates ranging from 0.90 to 1.12 (Figure 1).

    Three studies compared breast cancer risk between current or recent COC users (<6 months since last use) and never users of COCs (Figure 1). One of these studies reported no association between breast cancer risk and COC use. The other two studies found an increased relative risk of 1.19 to 1.33 with current or recent use. Both of these studies found an increased risk of breast cancer with current use of longer duration, with relative risks ranging from 1.03 with less than one year of COC use to approximately 1.4 with more than 8 to 10 years of COC use.

    Figure 1.

    Figure-1

    RR = relative risk; OR = odds ratio; HR = hazard ratio. “ever COC” are females with current or past COC use; “never COC use” are females that never used COCs.


    The following adverse reactions have been identified during post approval use of a 24-day regimen of norethindrone acetate 1 mg/ethinyl estradiol 0.020 mg tablets. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or evaluate a causal relationship to drug exposure.


    Vascular disorders: thrombosis/embolism (coronary artery, pulmonary, cerebral, deep vein).

    Hepatobiliary disorders: cholelithiasis, cholecystitis, hepatic adenoma, hemangioma of liver.

    Immune system disorders: hypersensitivity reaction.

    Skin and subcutaneous disorders: alopecia, rash (generalized and allergic), pruritus, skin discoloration.


    GI disorders: nausea, vomiting, abdominal pain.

    Musculoskeletal and connective tissue disorders: myalgia.


    Eye disorders: blurred vision, visual impairment, corneal thinning, change in corneal curvature (steepening).


    Infections and infestations: fungal infection, vaginal infection.


    Investigations: change in weight or appetite (increase or decrease), fatigue, malaise, peripheral edema, blood pressure increased.


    Nervous system disorders: headache, dizziness, migraine, loss of consciousness.


    Psychiatric disorders: mood swings, depression, insomnia, anxiety, suicidal ideation, panic attack, changes in libido.


    Renal and urinary disorders: cystitis-like syndrome.


    Reproductive system and breast disorders: breast changes (tenderness, pain, enlargement, and secretion), premenstrual syndrome, dysmenorrhea.


    Cardiovascular: chest pain, palpitations, tachycardia, myocardial infarction.

  • 7 DRUG INTERACTIONS

    Consult the labeling of the concurrently-used drug to obtain further information about interactions with COCs or the potential for enzyme alterations.

    7.1 Effects of Other Drugs on Combined Oral Contraceptives

    Substances diminishing the efficacy of COCs: Drugs or herbal products that induce certain enzymes, including cytochrome P450 3A4 (CYP3A4), may decrease the effectiveness of COCs or increase breakthrough bleeding. Some drugs or herbal products that may decrease the effectiveness of hormonal contraceptives include phenytoin, barbiturates, carbamazepine, bosentan, felbamate, griseofulvin, oxcarbazepine, rifampicin, topiramate and products containing St. John’s wort. Interactions between oral contraceptives and other drugs may lead to breakthrough bleeding and/or contraceptive failure. Counsel women to use an alternative method of contraception or a back-up method when enzyme inducers are used with COCs, and to continue back-up contraception for 28 days after discontinuing the enzyme inducer to ensure contraceptive reliability.

    Substances increasing the plasma concentrations of COCs: Co-administration of atorvastatin and certain COCs containing ethinyl estradiol increase AUC values for ethinyl estradiol by approximately 20%. Ascorbic acid and acetaminophen may increase plasma ethinyl estradiol concentrations, possibly by inhibition of conjugation. CYP3A4 inhibitors such as itraconazole or ketoconazole may increase plasma hormone concentrations.

    Human immunodeficiency virus (HIV)/ Hepatitis C virus (HCV) protease inhibitors and non­ nucleoside reverse transcriptase inhibitors: Significant changes (increase or decrease) in the plasma concentrations of estrogen and progestin have been noted in some cases of co-administration with HIV/HCV protease inhibitors or with non-nucleoside reverse transcriptase inhibitors.

    Antibiotics: There have been reports of pregnancy while taking hormonal contraceptives and antibiotics, but clinical pharmacokinetic studies have not shown consistent effects of antibiotics on plasma concentrations of synthetic steroids.

    7.2 Effects of Combined Oral Contraceptives on Other Drugs

    COCs containing ethinyl estradiol may inhibit the metabolism of other compounds. COCs have been shown to significantly decrease plasma concentrations of lamotrigine, likely due to induction of lamotrigine glucuronidation. This may reduce seizure control; therefore, dosage adjustments of lamotrigine may be necessary.

    Women on thyroid hormone replacement therapy may need increased doses of thyroid hormone because serum concentration of thyroid-binding globulin increases with use of COCs.

    7.3 Concomitant Use with HCV Combination Therapy – Liver Enzyme Elevation

    Do not co-administer MERZEE with HCV drug combinations containing ombitasvir/ paritaprevir/ritonavir, with or without dasabuvir, due to potential for ALT elevations [see Warnings and Precautions (5.3)].

    7.4 Interference with Laboratory Tests

    The use of contraceptive steroids may influence the results of certain laboratory tests, such as coagulation factors, lipids, glucose tolerance, and binding proteins.

  • 8 USE IN SPECIFIC POPULATIONS

    8.1 Pregnancy

    Risk Summary 
    There is no use for contraception in pregnancy; therefore, MERZEE should be discontinued during pregnancy. Epidemiologic studies and meta-analyses have not found an increased risk of genital or nongenital birth defects (including cardiac anomalies and limb-reduction defects) following exposure to COCs before conception or during early pregnancy.

    In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4 percent and 15 to 20 percent, respectively.

    8.2 Lactation

    Risk Summary 
    Contraceptive hormones and/or metabolites are present in human milk. COCs can reduce milk production in breast-feeding females. This reduction can occur at any time but is less likely to occur once breast-feeding is well-established. When possible, advise the nursing female to use other methods of contraception until she discontinues breast-feeding [see Dosage and Administration (2.2)]. The developmental and health benefits of breast-feeding should be considered along with the mother’s clinical need for MERZEE and any potential adverse effects on the breast-fed child from MERZEE or from the underlying maternal condition. 

    8.4 Pediatric Use

    Safety and efficacy of MERZEE have been established in women of reproductive age.
    Efficacy is expected to be the same in postpubertal adolescents under the age of 18 years as for users 18 years and older. Use of this product before menarche is not indicated.

    8.5 Geriatric Use

    MERZEE has not been studied in postmenopausal women and is not indicated in this population.

    8.6 Renal Impairment

    The pharmacokinetics of MERZEE has not been studied in subjects with renal impairment [see Clinical Pharmacology (12.3)].

    8.7 Hepatic Impairment

    The pharmacokinetics of MERZEE has not been studied in subjects with hepatic impairment. However, steroid hormones may be poorly metabolized in patients with hepatic impairment. Acute or chronic disturbances of liver function may necessitate the discontinuation of COC use until markers of liver function return to normal and COC causation has been excluded [see Contraindications (4) and Warnings and Precautions (5.2)].

    8.8 Body Mass Index

    The safety and efficacy of MERZEE in women with a body mass index (BMI) > 35 kg/m2 has not been evaluated [see Clinical Studies (14)].

  • 10 OVERDOSAGE

    There have been no reports of serious ill effects from overdose of oral contraceptives, including ingestion by children. Overdosage may cause withdrawal bleeding in females and nausea.

  • 11 DESCRIPTION

    Merzee (Norethindrone Acetate and Ethinyl Estradiol Capsules and Ferrous Fumarate Capsules) contain norethindrone acetate, a progestin, and ethinyl estradiol, an estrogen. MERZEE provides an oral contraceptive regimen consisting of 24 pink active soft gelatin capsules that contain the active ingredients, followed by 4 maroon non-hormonal placebo soft gelatin capsules as specified below:

  • 12 CLINICAL PHARMACOLOGY

    12.1 Mechanism of Action

    CHCs lower the risk of becoming pregnant primarily by suppressing ovulation.

    12.2 Pharmacodynamics

    No specific pharmacodynamic studies were conducted with MERZEE.

    12.3 Pharmacokinetics

    Absorption
    In a single-dose, crossover clinical study conducted in 39 healthy, non-smoking premenopausal women under fasting condition, MERZEE capsules were bioequivalent to norethindrone acetate 1 mg/ethinyl estradiol 0.020 mg tablets (24-day regimen tablets) based on the exposure (AUC) and peak concentration (Cmax) of norethindrone and ethinyl estradiol.

    Norethindrone acetate appears to be completely and rapidly deacetylated to norethindrone after oral administration, because the disposition of norethindrone acetate is indistinguishable from that of orally administered norethindrone. Norethindrone acetate and ethinyl estradiol are rapidly absorbed from norethindrone acetate/ethinyl estradiol tablets, with maximum plasma concentrations of norethindrone and ethinyl estradiol occurring 1 to 4 hours post-dose. Both are subject to first-pass metabolism after oral dosing, resulting in an absolute bioavailability of approximately 64% for norethindrone and 43% for ethinyl estradiol.

    The plasma norethindrone and ethinyl estradiol pharmacokinetics following single- and multiple-dose administrations of norethindrone acetate/ethinyl estradiol tablets in 17 healthy female volunteers are provided in Figures 2 and 3, and Table 1.

    Following multiple-dose administration of norethindrone acetate/ethinyl estradiol tablets, mean maximum concentrations of norethindrone and ethinyl estradiol were increased by 95% and 27%, respectively, as compared to single-dose administration. Mean norethindrone and ethinyl estradiol exposures (AUC values) were increased by 164% and 51% respectively, as compared to single-dose administration of norethindrone acetate/ethinyl estradiol tablets.

    Steady-state with respect to norethindrone was reached by Day 17 and steady-state with respect to ethinyl estradiol was reached by Day 13.

    Mean SHBG concentrations were increased by 150% from baseline (57.5 nmol/L) to 144 nmol/L at steady-state.

    Food Effect

    MERZEE may be administered without regard to meals.

    A single-dose administration of MERZEE capsules with food in 38 healthy, non-smoking premenopausal women decreased the maximum concentration of norethindrone and ethinyl estradiol by 38% and 33%, respectively. Food intake did not affect the extent of ethinyl estradiol absorption, but increased the extent of norethindrone absorption by 19%.

    Distribution
    Volume of distribution of norethindrone and ethinyl estradiol ranges from 2 to 4 L/kg. Plasma protein binding of both steroids is extensive (>95%); norethindrone binds to both albumin and SHBG, whereas ethinyl estradiol binds only to albumin. Although ethinyl estradiol does not bind to SHBG, it induces SHBG synthesis.

    Metabolism
    Norethindrone undergoes extensive biotransformation, primarily via reduction, followed by sulfate and glucuronide conjugation. The majority of metabolites in the circulation are sulfates, with glucuronides accounting for most of the urinary metabolites.

    Ethinyl estradiol is also extensively metabolized, both by oxidation and by conjugation with sulfate and glucuronide. Sulfates are the major circulating conjugates of ethinyl estradiol and glucuronides predominate in urine. The primary oxidative metabolite is 2-hydroxy ethinyl estradiol, formed by the CYP3A4 isoform of cytochrome P450. Part of the first-pass metabolism of ethinyl estradiol is believed to occur in gastrointestinal mucosa. Ethinyl estradiol may undergo enterohepatic circulation.

    Excretion
    Norethindrone and ethinyl estradiol are excreted in both urine and feces, primarily as metabolites. Plasma clearance values for norethindrone and ethinyl estradiol are similar (approximately 0.4 L/hr/kg). Steady-state elimination half-lives of norethindrone and ethinyl estradiol following administration of norethindrone acetate/ethinyl estradiol tablets are approximately 8 hours and 14 hours, respectively.

    Drug Interactions
    No drug-drug interaction studies were conducted with MERZEE.

    [See Warnings and Precautions (5.2, 5.11).]

  • 14 CLINICAL STUDIES

    The data presented in Section 14 are from a clinical trial conducted with a 24-day regimen of norethindrone acetate 1 mg/ethinyl estradiol 0.020 mg tablets. MERZEE capsules are bioequivalent to these norethindrone acetate/ethinyl estradiol tablets.

    In a clinical study, 743 women 18 to 45 years of age were studied to assess the efficacy of norethindrone acetate/ethinyl estradiol tablets, for up to six 28-day cycles providing a total of 3,823 treatment-cycles of exposure. The racial demographic of all enrolled women was: 70% Caucasian, 16% African-American, 10% Hispanic, 2% Asian and 2% Other. Women with body mass index (BMI) greater than 35 mg/m2 were excluded from the study. The weight range for those women treated was 90 to 260 pounds, with a mean weight of 147 pounds. Among the women in the study, about 40% had not used hormonal contraception immediately prior to enrolling in this study.

    A total of 583 women completed 6 cycles of treatment. There were a total of 5 on-treatment pregnancies in 3,565 treatment cycles during which no backup contraception was used. The Pearl Index for norethindrone acetate/ethinyl estradiol tablets was 1.82 (95% confidence interval 0.59 - 4.25).

  • 17 PATIENT COUNSELING INFORMATION

    See FDA-approved patient labeling (Patient Information).

    Counsel patients on the following information:
     Cigarette smoking increases the risk of serious cardiovascular events from COC use, and women who are over 35 years old and smoke should not use COCs.
     Increased risk of VTE compared to non-users of COCs is greatest after initially starting a COC or restarting (following a 4-week or greater pill-free interval) the same or a different COC.
     MERZEE does not protect against HIV infection (AIDS) and other sexually transmitted infections.
     The Warnings and Precautions associated with COCs.
     MERZEE is not to be used during pregnancy; if pregnancy occurs during use of MERZEE, instruct the patient to stop further intake.
     Take one capsule daily by mouth at the same time every day. Instruct patients what to do in the event pills are missed. See “What to Do if You Miss Capsules” section in FDA-approved patient labeling.
     Use a back-up or alternative method of contraception when enzyme inducers are used with MERZEE.
     COCs may reduce breast milk production. This is less likely to occur if breastfeeding is well established.
     Women who start COCs postpartum, and who have not yet had a period, should use an additional method of contraception until they have taken a pink capsule for 7 consecutive days.
     Amenorrhea may occur. Rule out pregnancy in the event of amenorrhea in two or more consecutive cycles.

    Guide for Using MERZEE (norethindrone acetate and ethinyl estradiol capsules and ferrous fumarate capsules)

    WARNING TO WOMEN WHO SMOKE


    Do not use MERZEE if you smoke cigarettes and are over 35 years old. Smoking increases your risk of serious cardiovascular side effects (heart and blood vessel problems) from birth control pills, including death from heart attack, blood clots or stroke. This risk increases with age and the number of cigarettes you smoke.

    Birth control pills help to lower the chances of becoming pregnant when taken as directed. They do not protect against HIV infection (AIDS) and other sexually transmitted infections.

    What is MERZEE?
    MERZEE is a birth control pill. It contains two female hormones, an estrogen called ethinyl estradiol, and a progestin called norethindrone acetate.

    How well does MERZEE work?
    Your chance of getting pregnant depends on how well you follow the directions for taking your birth control pills. The better you follow the directions, the less chance you have of getting pregnant.

    Based on the results of one clinical study of a 24-day regimen of norethindrone acetate 1 mg/ethinyl estradiol 0.020 mg tablets lasting six months, about 1 to 4 out of 100 women may get pregnant during the first year they use MERZEE.
    Women with a BMI above 35 kg/m2 were not studied in the clinical trial, so it is not known how well MERZEE protects against pregnancy in such women. If you are overweight, discuss with your healthcare provider whether MERZEE is the best choice for you.

    The following chart shows the chance of getting pregnant for women who use different methods of birth control. Each box on the chart contains a list of birth control methods that are similar in effectiveness. The most effective methods are at the top of the chart. The box on the bottom of the chart shows the chance of getting pregnant for women who do not use birth control and are trying to get pregnant.

    Figure-4

    How do I take MERZEE?
    1. Be sure to read these directions before you start taking your capsules or anytime you are not sure what to do.
    2. The right way to take the capsule is to take one capsule every day at the same time in the order directed on the package. MERZEE can be taken without regard to meals.
    If you miss capsules you could get pregnant. This includes starting the pack late. The more capsules you miss, the more likely you are to get pregnant. See "WHAT TO DO IF YOU MISS CAPSULES” below.
    3. Many women have spotting or light bleeding at unexpected times, or may feel sick to their stomach during the first 1 to 3 packs of capsules.
    If you do have spotting or light bleeding or feel sick to your stomach, do not stop taking the capsules. The problem will usually go away. If it does not go away, check with your healthcare provider.
    4. Missing capsules can also cause spotting or light bleeding, even when you make up these missed capsules.
    On the days you take two capsules, to make up for missed capsules, you could also feel a little sick to your stomach.
    5. If you have vomiting (within 3 to 4 hours after you take your capsule), you should follow the instructions for "WHAT TO DO IF YOU MISS CAPSULES." If you have diarrhea or if you take certain medicines, including some antibiotics and some herbal products such as St. John's Wort, your capsules may not work as well.
    Use a back-up method (such as condoms and spermicides) until you check with your healthcare provider.
    6. If you have trouble remembering to take MERZEE, talk to your healthcare provider about how to make capsule-taking easier or about using another method of birth control.
    7. If you have any questions or are unsure about the information in this leaflet, call your healthcare provider.

    Before You Start Taking Your MERZEE

    1. Decide What Time of Day You Want to Take Your Capsule. It is important to take norethindrone acetate and ethinyl estradiol capsules and ferrous fumarate capsules in the order directed on the package at the same time every day. MERZEE can be taken without regard to meals.

    2. Look at Your Capsule Pack – It has 28 Capsules

    The MERZEE -pill pack has 24 "active" pink capsules (with hormones) to be taken for 24 days, followed by 4 "reminder" maroon capsules (without hormones) to be taken for the next four days.

    Figure-5


     3. Also look for:
    a) Where on the pack to start taking capsules,
    b) In what order to take the capsules (follow the arrows shown in the picture above)
    c) The week numbers as shown in the picture above.

    4. Be sure you have ready at all times
    a) another kind of birth control (such as a condoms and spermicide) to use as a back-up in case you miss capsules, and
    b) an extra, full pill pack.

    When to Start the First Pack of Capsules

    You have a choice for which day to start taking your first pack of capsules. Decide with your healthcare provider which is the best day for you. Pick a time of day which will be easy to remember.

    Day 1 Start:
    1. Pick the day label strip that starts with the first day of your period (this is the day you start bleeding or spotting, even if it is almost midnight when the bleeding begins).
    2. Place this day label strip on the capsule dispenser over the area that has the days of the week (starting with Sunday) printed on the plastic.
    3. Take the first pink pill of the pack during the first 24 hours of your period.
    4. You will not need to use a back-up method of birth control, since you are starting the capsule at the beginning of your period. However, if you start MERZEE later than the first day of your period, you should use another method of birth control (such as a condom and spermicide) as a back-up method until you have taken 7 pink capsules.

    Sunday Start:
    1. Take the first pink capsule of the pack on the Sunday after your period starts, even if you are still bleeding. If your period begins on Sunday, start the pack that same day.
    2. Use another method of birth control (such as a condom and spermicide) as a back-up method if you have sex anytime from the Sunday you start your first pack until the next Sunday (7 days). This also applies if you start MERZEE after having been pregnant, and you have not had a period since your pregnancy.

    When You Switch From a Different Birth Control Tablet
    When switching from another birth control pill, finish all the tablets, then MERZEE should be started on the same day that a new pack of the previous birth control tablet would have been started.

    When You Switch From Another Type of Birth Control Method
    When switching from a transdermal patch or vaginal ring, finish the 21 days of use, wait 7 days, then MERZEE should be started when the next application would have been due.

    When switching from an injection, MERZEE should be started when the next injection would have been due. When switching from an intrauterine device or an implant, MERZEE should be started on the day of removal.

    What to Do During the Month
    1. Take one capsule at the same time every day until the pack is empty.
    Do not skip capsules even if you are spotting or bleeding between monthly periods or feel sick to your stomach (nausea).

    2. Do not skip capsules even if you do not have sex very often.
    When you finish a pack of capsules, start the next pack on the day after your last maroon capsule. Do not wait any days between packs.

    What to Do if You Miss Capsules
    MERZEE may not be as effective if you miss any pink capsules, especially if you miss the first few or the last few pink capsules in a pack.

    If you miss 1 pink capsule:
    1. Take the capsule as soon as you remember. Take the next capsule at your regular time. This means you may take two capsules in one day.
    2. You do not need to use a back-up birth control method if you have sex.

    If you miss 2 pink capsules in a row in week 1 OR week 2 of your pack:
    1. Take two capsules on the day you remember and two capsules the next day.
    2. Then take one capsule a day until you finish the pack.
    3. You could become pregnant if you have sex in the 7 days after you restart your capsules. You must use another birth control method (such as a condom and spermicide) as a back-up for those 7 days.

    If you miss 2 pink capsules in a row in week 3 or week 4 of your pack:
    1. If you are a Day 1 Starter:
    Throw out the rest of the MERZEE pack and start a new pack that same day.

    If you are a Sunday Starter:
    Keep taking one capsule every day until Sunday. On Sunday, throw out the rest of the pack and start a new pack of capsules that same day.

    2. You could become pregnant if you have sex in the 7 days after you restart your capsules. You must use another birth control method (such as a condom and spermicide) as a back-up for those 7 days.

    3. You may not have your period this month but this is expected. However, if you miss your period two months in a row, call your healthcare provider because you might be pregnant.

    If you miss 3 or more pink capsules in a row during any week:
    1. If you are a Day 1 Starter:
    Throw out the rest of the capsule pack and start a new pack that same day.

    If you are a Sunday Starter:
    Keep taking 1 capsule every day until Sunday. On Sunday, throw out the rest of the pack and start a new pack of capsules that same day.

    2. You could become pregnant if you have sex on the days when you missed capsules or during the first 7 days after you restart your capsules. You must use another birth control method (such as a condom and spermicide) as a back-up the next time you have sex and for the first 7 days after you restart your capsules.
    3. You may not have your period this month but this is expected. However, if you miss your period two months in a row, call your healthcare provider because you might be pregnant.

    If you miss any of the 4 maroon capsules in Week 4:
    1. Throw away the capsules you missed.
    2. Keep taking one capsule each day until the pack is empty.
    3. You do not need a back-up method.
    4. Start the next pack of MERZEE as scheduled.

    Finally, if you are still not sure what to do about the capsules you have missed:
    1. Use a back-up method (such as a condom and spermicide) anytime you have sex.
    2. Contact your healthcare provider and continue taking one active pink capsule each day until otherwise directed.

    Who should not take MERZEE?
    Your healthcare provider will not give you MERZEE if you have:
     Ever had blood clots in your arms, legs (deep vein thrombosis), lungs (pulmonary embolism), or eyes (retinal thrombosis)
     Ever had a stroke
     Ever had a heart attack
     Certain heart valve problems or heart rhythm abnormalities that can cause blood clots to form in the heart
     An inherited problem with your blood that makes it clot more than normal
     High blood pressure that medicine cannot control
     Diabetes with kidney, eye, nerve, or blood vessel damage
     Ever had certain kinds of severe migraine headaches with aura, numbness, weakness or changes in vision, or have any migraine headaches if you are over age 35
     Ever had breast cancer, which may be sensitive to female hormones
     Liver disease, including liver tumors
     Take any Hepatitis C drug combination containing ombitasvir/paritaprevir/ritonavir, with or without dasabuvir. This may increase levels of the liver enzyme “alanine aminotransferase” (ALT) in the blood.

    Also, do not take birth control pills if you:
     Smoke and are over 35 years old
     Are or suspect you are pregnant
     Have any unexplained bleeding from the vagina
    Birth control pills may not be a good choice for you if you have ever had jaundice (yellowing of the skin or eyes) caused by pregnancy, also called cholestasis of pregnancy.

    Tell your healthcare provider if you have ever had any of the above conditions (your healthcare provider may recommend another method of birth control).

    What else should I know about taking MERZEE?
    Birth control pills do not protect you against any sexually transmitted infection, including HIV, the virus that causes AIDS.

    Do not skip any pills, even if you do not have sex often.

    If you miss a period, you could be pregnant. However, some women miss periods or have light periods on birth control pills, even when they are not pregnant. Contact your healthcare provider for advice if you:
     Think you are pregnant
     Miss one period and have not taken your birth control pills every day
     Miss two periods in a row

    Birth control pills should not be taken during pregnancy. However, birth control pills taken by accident during pregnancy are not known to cause birth defects.

    You should stop MERZEE at least four weeks before you have surgery and not restart it until at least two weeks after the surgery, due to an increased risk of blood clots.

    If you are breastfeeding, consider another birth control method until you are ready to stop breastfeeding. Birth control pills that contain estrogen, like MERZEE, may decrease the amount of milk you make. A small amount of the pill's hormones pass into breast milk.

    Tell your healthcare provider about all medicines and herbal products that you take. Some medicines and herbal products may make birth control pills less effective, including:
     barbiturates
     bosentan
     carbamazepine
     felbamate
     griseofulvin
     oxcarbazepine
     phenytoin
     rifampin
     St. John’s wort
     topiramate

    Use a back-up or alternative birth control method when you take medicines that may make birth control pills less effective.

    Birth control pills may interact with lamotrigine, an anticonvulsant used for epilepsy. This may increase the risk of seizures, so your healthcare provider may need to adjust the dose of lamotrigine.

    If you have vomiting or diarrhea, your birth control pills may not work as well. Use another birth control method, like a condom and spermicide, until you check with your healthcare provider.

    Women on thyroid hormone replacement therapy may need increased doses of thyroid hormone.

    If you are scheduled for any laboratory tests, tell your healthcare provider that you are taking birth control pills. Certain blood tests may be affected by birth control pills.

    What are the most serious risks of taking MERZEE?
    Like pregnancy, birth control pills increase the risk of serious blood clots, especially in women who have other risk factors, such as smoking, obesity, or age greater than 35. This increased risk is highest when you first start taking birth control pills and when you restart the same or different birth control pills after not using them for a month or more.
    It is possible to die from a problem caused by a blood clot, such as a heart attack or a stroke.

    Some examples of serious blood clots are blood clots in the:
    Legs (deep vein thrombosis)
    Lungs (pulmonary embolus)
    Eyes (loss of eyesight)
    Heart (heart attack)
    Brain (stroke)

    Women who take birth control pills may get:
    High blood pressure
    Gallbladder problems
    Rare cancerous or noncancerous liver tumors  


    All of these events are uncommon in healthy women.

    Call your healthcare provider right away if you have:
    Persistent leg pain
    Sudden shortness of breath
    Sudden blindness, partial or complete
    Severe pain or pressure in your chest
    Sudden, severe headache unlike your usual headaches
    Weakness or numbness in an arm or leg, or trouble speaking
    Yellowing of the skin or eyeballs


    What are the common side effects of birth control pills?
    The most common side effects of birth control pills are:
     Spotting or bleeding between menstrual periods
     Nausea
     Breast tenderness
     Headache

    These side effects are usually mild and usually disappear with time.
    Less common side effects are:
    Acne
    Less sexual desire
    Bloating or fluid retention
    Blotchy darkening of the skin, especially on the face
    High blood sugar, especially in women who already have diabetes
    High fat (cholesterol, triglyceride) levels in the blood
    Depression, especially if you have had depression in the past. Call your healthcare provider immediately if you have any thoughts of harming yourself
    Problems tolerating contact lenses
    Weight gain

    This is not a complete list of possible side effects. Talk to your healthcare provider if you develop any side effects that concern you. You may report side effects to the FDA at 1-800-FDA-1088.

    No serious problems have been reported from a birth control pill overdose, even when accidentally taken by children.


    Do birth control pills cause cancer?
    It is not known if hormonal birth control pills cause breast cancer. Some studies, but not all, suggest that there could be a slight increase in the risk of breast cancer among current users with longer duration of use.

    If you have breast cancer now, or have had it in the past, do not use hormonal birth control because some breast cancers are sensitive to hormones.


    Women who use birth control pills may have a slightly higher chance of getting cervical cancer. However, this may be due to other reasons such as having more sexual partners.

    What should I know about my period when taking MERZEE?
    Irregular vaginal bleeding or spotting may occur while you are taking MERZEE. Irregular bleeding may vary from slight staining between menstrual periods to breakthrough bleeding, which is a flow much like a regular period. Irregular bleeding occurs most often during the first few months of oral contraceptive use, but may also occur after you have been taking the pill for some time. Such bleeding may be temporary and usually does not indicate any serious problems. It is important to continue taking your pills on schedule. If the bleeding occurs in more than one cycle, is unusually heavy, or lasts for more than a few days, call your healthcare provider.

    Some women may not have a menstrual period but this should not be cause for alarm as long has you have taken the pills according to direction.

    What if I miss my scheduled period when taking MERZEE?
    It is not uncommon to miss your period. However, if you go two or more months in a row without a period, or you miss your period after a month where you did not take all your pills correctly, call your healthcare provider because you may be pregnant. Also notify your healthcare provider if you have symptoms of pregnancy such as morning sickness or unusual breast tenderness. Stop taking MERZEE if you are pregnant.

    What if I want to become pregnant?
