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 are contraindicated inwomen who are over 35 years of age and smoke [see Contraindications (4)].
Norethindrone and ethinyl estradiol tablets (chewable) 0.4 mg/0.035 mg and ferrous fumarate tablets are dispensed in a blister card [see How Supplied/Storage and Handling (16)] . Norethindrone and ethinyl estradiol tablets (chewable) 0.4 mg/0.035 mg and ferrous fumarate tablets may be started using either a Day 1 start or a Sunday start (see Table 1). For the first cycle of a Sunday Start regimen, an additional method of contraception should be used until after the first 7 consecutive days of administration.
The Norethindrone and ethinyl estradiol tablets, USP may be swallowed whole or chewed. If Norethindrone and ethinyl estradiol tablets, USP are chewed, the patient should drink a full glass (8 ounces) of liquid immediately after swallowing.

Norethindrone and ethinyl estradiol tablets, USP (chewable) 0.4 mg/0.035 mg and ferrous fumarate tablets are available in blister cards.
Each blister card contains 28 tablets in the following order:
Norethindrone and ethinyl estradiol tablets (chewable) 0.4 mg/0.035 mg is contraindicated in females who are known to have or develop the following conditions:
Impaired Liver Function
Do not use norethindrone and ethinyl estradiol tablets (chewable) 0.4 mg/0.035 mg and ferrous fumarate tablets in women with liver disease, such as 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 norethindrone and ethinyl estradiol tablets (chewable) 0.4 mg/0.035 mg and ferrous fumarate tablets if jaundice develops.
Liver Tumors
Norethindrone and ethinyl estradiol tablets (chewable) 0.4 mg/0.035 mg and ferrous fumarate tablets are contraindicated in women with benign and malignant liver tumors [see Contraindications (4)]. Hepatic adenomas are associated with COC use. An estimate of the attributable risk is 3.3 cases/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 risk of liver cancers in COC users is less than one case per million users.
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 FEMCON Fe prior to starting therapy with the combination drug regimen ombitasvir/paritaprevir/ritonavir, with or without dasabuvir [see Contraindications (4)]. FEMCON Fe can be restarted approximately 2 weeks following completion of treatment with the Hepatitis C combination drug regimen.
Norethindrone and ethinyl estradiol tablets (chewable) 0.4 mg/0.035 mg and ferrous fumarate tablets are 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 norethindrone and ethinyl estradiol tablets (chewable) 0.4 mg/0.035 mg and ferrous fumarate tablets 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.
Studies suggest a small increased relative risk of developing gallbladder disease among COC users. Use of COCs may 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.
Carefully monitor prediabetic and diabetic women who take norethindrone and ethinyl estradiol tablets (chewable) 0.4 mg/0.035 mg and ferrous fumarate tablets. COCs may decrease glucose tolerance.
Consider alternative contraception for women with uncontrolled dyslipidemia. 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.
If a woman taking norethindrone and ethinyl estradiol tablets (chewable) 0.4 mg/0.035 mg and ferrous fumarate tablets develops new headaches that are recurrent, persistent, or severe, evaluate the cause and discontinue norethindrone and ethinyl estradiol tablets (chewable) 0.4 mg/0.035 mg and ferrous fumarate tablets if indicated.
Consider discontinuation of norethindrone and ethinyl estradiol tablets (chewable) 0.4 mg/0.035 mg and ferrous fumarate tablets in the case of increased frequency or severity of migraine during COC use (which may be prodromal of a cerebrovascular event).
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 contraceptive product.
Amenorrhea and Oligomenorrhea
Women who use norethindrone and ethinyl estradiol tablets (chewable) 0.4 mg/0.035 mg and ferrous fumarate tablets may experience amenorrhea. Some women may experience amenorrhea or oligomenorrhea after discontinuation of COCs, 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 tablets 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.
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 norethindrone and ethinyl estradiol tablets (chewable) 0.4 mg/0.035 mg and ferrous fumarate tablets use if pregnancy is confirmed.
Administration of COCs to induce withdrawal bleeding should not be used as a test for pregnancy [see Use in Specific Populations (8.1)].
Carefully observe women with a history of depression and discontinue norethindrone and ethinyl estradiol tablets (chewable) 0.4 mg/0.035 mg and ferrous fumarate tablets if depression recurs to a serious degree.
Norethindrone and ethinyl estradiol tablets (chewable) 0.4 mg/0.035 mg 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 Postmarketing Experience (6.2)].
The estrogen component of COCs may raise the serum concentrations of thyroxine-binding globulin, sec hormone-binding globulin, and cortisol-binding globulin. The dose of replacement thyroid hormone or cortisol therapy may need to be increased.
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.
In women with hereditary angioedema, exogenous estrogens may induce or exacerbate symptoms of angioedema.
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 norethindrone and ethinyl estradiol tablets (chewable) 0.4 mg/0.035 mg and ferrous fumarate tablets.
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 - 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 - 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 8-10 years of COC use.

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 serious adverse reactions with the use of COCs are discussed elsewhere in the labeling:
The following adverse reactions are commonly reported by COC users. Because these reactions are voluntarily reported by from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure:
Consult the labeling of concurrently used drugs to obtain further information about interactions with hormonal contraceptives or the potential for enzyme alterations.
Substances decreasing the plasma concentrations of COCs and potentially diminishing the efficacy of COCs:
Drugs or herbal products that induce certain enzymes, including cytochrome P450 3A4 (CYP3A4), may decrease the plasma concentrations of COCs and potentially diminish 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, rifabutin, rufinamide, aprepitant, and products containing St. John’s wort. Interactions between hormonal 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.
Colesevelam:
Colesevelam, a bile acid sequestrant, given together with a COC, has been shown to significantly decrease the AUC of EE. The drug interaction between the contraceptive and colesevelam was decreased when the two drug products were given 4 hours apart.
Substances increasing the plasma concentrations of COCs:
Co-administration of atorvastatin or rosuvastatin and certain COCs containing EE increase AUC values for EE by approximately 20 to 25%. Ascorbic acid and acetaminophen may increase plasma EE concentrations, possibly by inhibition of conjugation. CYP3A4 inhibitors, such as itraconazole, fluconazole, grapefruit juice, 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/or progestin have been noted in some cases of co-administration with HIV protease inhibitors (decrease [e.g., nelfinavir, ritonavir, darunavir/ritonavir, (fos)amprenavir/ritonavir, lopinavir/ritonavir, and tipranavir/ritonavir] or increase [e.g., indinavir and atazanavir/ritonavir])/HCV protease inhibitors (decrease [e.g., nevirapine] or increase [e.g., etravirine]).
COCs containing EE may inhibit the metabolism of other compounds (e.g., cyclosporine prednisolone, theophylline, tizanidine, and voriconazole) and increase their plasma concentrations. COCs have been shown to decrease plasma concentrations of acetaminophen, clofibric acid, morphine, salicylic acid, temazepam and lamotrigine. Significant decrease in plasma concentration of lamotrigine has been shown, 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 the serum concentration of thyroid-binding globulin increases with use of COCs [see Warnings and Precautions (5.11)].
There is little or no increased risk of birth defects in women who inadvertently use COCs during early pregnancy. Epidemiologic studies and meta-analyses have not found an increased risk of genital or non-genital birth defects (including cardiac anomalies and limb reduction defects) following exposure to low dose COCs prior to conception or during early pregnancy.
Do not use COCs to induce withdrawal bleeding as a test for pregnancy. Do not use COCs during pregnancy to treat threatened or habitual abortion.
Advise the nursing mother to use other forms of contraception, when possible, until she has weaned her child. COCs can reduce milk production in breastfeeding mothers. This is less likely to occur once breastfeeding is well-established; however, it can occur at any time in some women. Small amounts of oral contraceptive steroids and/or metabolites are present in breast milk.
Safety and efficacy of norethindrone and ethinyl estradiol tablets (chewable) 0.4 mg/0.035 mg and ferrous fumarate tablets have been established in women of reproductive age. Efficacy is expected to be the same in post-pubertal adolescents under the age of 18 years as for users 18 years and older. Use of this product before menarche is not indicated.
Norethindrone and ethinyl estradiol tablets (chewable) 0.4 mg/0.035 mg and ferrous fumarate tablets have not been studied in postmenopausal women and is not indicated in this population.
The pharmacokinetics of norethindrone and ethinyl estradiol tablets (chewable) 0.4 mg/0.035 mg and ferrous fumarate tablets have not been studied in women 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)].
Norethindrone and ethinyl estradiol tablets, USP (chewable) 0.4 mg/0.035 mg and ferrous fumarate tablets are combinational contraceptive containing the progestational compound norethindrone and the estrogenic compound ethinyl estradiol. The packaging includes 21 white to off white tablets composed of norethindrone and ethinyl estradiol followed by 7 brown ferrous fumarate (placebo) tablets. The chemical name for norethindrone is 17-hydroxy-19-nor-17α-pregn-4-en-20-yn-3-one and for ethinyl estradiol the chemical name is 19-nor-17α-pregna-1,3,5(10)-trien-20-yne-3,17-diol. The structural formulas are:
The active white to off white (norethindrone and ethinyl estradiol tablets (chewable)) tablets contain 0.4 mg norethindrone and 0.035 mg ethinyl estradiol, and the following inactive ingredients: dibasic calcium phosphate dihydrate, lactose monohydrate, magnesium stearate, maltodextrin, povidone, sodium starch glycolate, spearmint flavor and sucralose.
The brown (ferrous fumarate tablets) tablets contain crospovidone, ferrous fumarate, microcrystalline cellulose, magnesium stearate, and pregelatinized starch (maize). The ferrous fumarate tablets do not serve any therapeutic purpose.
COCs lower the risk of becoming pregnant primarily by suppressing ovulation. Other possible mechanisms may include cervical mucus changes that inhibit sperm penetration and endometrial changes that reduce the likelihood of implantation.
No specific pharmacodynamic studies were conducted with norethindrone and ethinyl estradiol tablets (chewable) 0.4 mg/0.035 mg and ferrous fumarate tablets.
Absorption
Ethinyl estradiol and norethindrone are rapidly absorbed with maximum plasma concentrations occurring within 2 hours after norethindrone and ethinyl estradiol tablets (chewable) 0.4 mg/0.035 mg and ferrous fumarate tablets administration (see Table 1). Norethindrone appears to be completely absorbed following oral administration; however, it is subject to first-pass metabolism resulting in an absolute bioavailability of approximately 65 percent. Large intersubject variability is reflected in a 3- to 5-fold variation in norethindrone bioavailability. Ethinyl estradiol bioavailability is approximately 43 percent due to small-intestinal and hepatic first-pass metabolism.

Food Effect:
Single-dose administration of norethindrone and ethinyl estradiol tablets (chewable) 0.4 mg/0.035 mg and ferrous fumarate tablets with food decreased the maximum norethindrone and ethinyl estradiol concentration by 53 percent and 47 percent, respectively; the extent of norethindrone and ethinyl estradiol absorption (AUC values) was not affected by food administration.
Distribution
Norethindrone is 36 percent bound to sex hormone-binding globulin (SHBG) and 61 percent bound to albumin. Ethinyl estradiol is not bound to SHBG but is highly (98.5 percent) bound to albumin. Volume of distribution of norethindrone and ethinyl estradiol ranges from 2 to 4 L/kg.
Metabolism
Norethindrone undergoes extensive biotransformation, primarily via reduction, followed by sulfate and glucuronide conjugation; less than 5 percent of a norethindrone dose is excreted unchanged; greater than 50 percent and 20 to 40 percent of a dose is excreted in urine and feces, respectively. 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, which is formed by the CYP3A4 isoform of cytochrome P450.
Excretion
Plasma clearance values for norethindrone and ethinyl estradiol are similar (approximately 0.4 L/hr/kg). Ethinyl estradiol and norethindrone are excreted in both urine and feces, primarily as metabolites. Ethinyl estradiol is excreted in urine and feces as glucuronides and sulfates, and about 28 to 43 percent undergoes enterohepatic circulation. The mean terminal elimination half-lives of norethindrone and ethinyl estradiol following single dose administration of norethindrone and ethinyl estradiol tablets (chewable) 0.4 mg/0.035 mg and ferrous fumarate tablets are approximately 9 hours and 17 hours, respectively.
[See Warnings and Precautions (5.10) and Use in Specific Populations (8.1).]
The data presented in Section 14 are from a clinical trial conducted with norethindrone 0.4 mg/ethinyl estradiol 35 mcg tablets. Norethindrone and ethinyl estradiol tablets (chewable) 0.4 mg/0.035 mg and ferrous fumarate tablets are bioequivalent to these norethindrone acetate/ethinyl estradiol tablets.
In a multicenter open-label clinical trial, 1,970 women, 98% of whom were 16 to 39 years of age, were studied for up to 31 cycles (28 days per cycle) to assess the efficacy of norethindrone /ethinyl estradiol tablets, completing the equivalent of 20,230 cycles of exposure. The racial demographic of all enrolled women was: Caucasian (56%), African-American (14%), and Other (30%) (Hispanic, Native American, etc.). Of treated women, 10% were lost to follow-up, 11% discontinued related to cycle control and 7% discontinued due to other adverse events
The pregnancy rate (Pearl Index [PI]) in all 1,970 women was 1.48 pregnancies per 100 women-years of use (95% confidence interval 0.94 to 2.22), based on 23 pregnancies that occurred after the onset of treatment of norethindrone /ethinyl estradiol tablets.
Norethindrone and ethinyl estradiol tablets, USP (chewable) 0.4 mg/0.035 mg and ferrous fumarate tablets are available in a 28-day regimen of blister pack (NDC: 79929-005-05) as follows:

What is the most important information I should know about norethindrone and ethinyl estradiol tablets (chewable) 0.4 mg/0.035 mg and ferrous fumarate tablets?
Do not use norethindrone and ethinyl estradiol tablets (chewable) 0.4 mg/0.035 mg and ferrous fumarate tablets 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.
What are norethindrone and ethinyl estradiol tablets (chewable) 0.4 mg/0.035 mg and ferrous fumarate tablets?
Norethindrone and ethinyl estradiol tablets (chewable) 0.4 mg/0.035 mg and ferrous fumarate tablets are birth control pills (oral contraceptive) used by women to prevent pregnancy.
How does norethindrone and ethinyl estradiol tablets (chewable) 0.4 mg/0.035 mg and ferrous fumarate tablets work for contraception?
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 28-day regimen of norethindrone 0.4 mg/ethinyl estradiol 35 mcg tablets, about 1 to 2 out of 100 women may get pregnant during the first year they use norethindrone and ethinyl estradiol tablets (chewable) 0.4 mg/0.035 mg and ferrous fumarate tablets.
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.

Does hormonal birth control cause cancer?
It is not known if hormonal birth control pills causes 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.
