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 in women who are over 35 years of age and smoke [see Contraindications (4)].
Previfem® (norgestimate/ethinyl estradiol tablets) and Tri-Previfem® (norgestimate/ethinyl estradiol tablets) are indicated for use by females of reproductive potential to prevent pregnancy [see Clinical Studies (14)].
Tri-Previfem® (norgestimate/ethinyl estradiol tablets) is indicated for the treatment of moderate acne vulgaris in females at least 15 years of age, who have no known contraindications to oral contraceptive therapy and have achieved menarche. Previfem® (norgestimate/ethinyl estradiol tablets) should be used for the treatment of acne only if the patient desires an oral contraceptive for birth control [see Clinical Studies (14)].
Previfem® (norgestimate/ethinyl estradiol tablets) and Tri-Previfem® (norgestimate/ethinyl estradiol tablets) are dispensed in a blister pack tablet dispenser [see How Supplied/Storage and Handling (16)].
Previfem® (norgestimate/ethinyl estradiol tablets) and Tri-Previfem® (norgestimate/ethinyl estradiol 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.

Starting Previfem® or Tri-Previfem® after Childbirth
Previfem® and Tri-Previfem® come in a blister pack pill dispenser. Read the instructions below for using the blister pack pill dispenser.
The blister package consists of three parts, the calendar label, the sleeve and the blister pack containing 28 individually sealed pills. Note that the pills are arranged in four numbered rows of 7 pills, with the pre-printed days of the week printed above them. Refer to the sample of the blister pack below:
Previfem® consists of 21 blue “active” birth control pills and 7 light green “reminder” pills.
Tri-Previfem® consists of 7 white “active” pills, 7 light-blue “active” pills, 7 blue “active” pills and 7 light green “reminder” pills.
There are two ways to start taking birth-control pills, Sunday Start or Day 1 Start.
How to use Blister Cards for the 28 tablets
1. If Sunday Start, the patient discards the stickers and takes the first active pill on the first Sunday after their menstrual period begins. Due to the potential risk of becoming pregnant, use additional non-hormonal contraception (such as condoms and spermicide) for the first seven days of the patient’s first cycle pack of Previfem® or Tri-Previfem®.
2. If Day 1 Start, the patient picks the Days of the Week Sticker that starts the first day of their period. When the patient has picked the right sticker, they need to throw away the others and place the sticker on the blister card over the preprinted days of the week and make sure it lines up with the pills.
3. The patient removes the first pill by pushing down on the pill and waits 24 hours to take their next pill. The patient continues to take one pill each day until all the pills have been taken.
4. The pill should be taken at the same time each day.
5. After taking the last pill, the patient starts a new blister pack the very next day, no matter when their next period starts.
6. The patient should take the pills in each new package as before and start with the pill on the first row and take one pill each day, left to right, until the last pill has been taken.
| Take the tablet as soon as possible. Continue taking one tablet a day until the pack is finished. |
| Take the two missed tablets as soon as possible and the next two active tablets the next day. Continue taking one tablet a day until the pack is finished. Additional non-hormonal contraception (such as condoms and spermicide) should be used as back-up if the patient has sex within 7 days after missing tablets. |
| Day 1 start: Throw out the rest of the pack and start a new pack that same day. Sunday start: Continue taking one tablet a day until Sunday, then throw out the rest of the pack and start a new pack that same day. Additional non-hormonal contraception (such as condoms and spermicide) should be used as back-up if the patient has sex within 7 days after missing tablets. |
In case of severe vomiting or diarrhea, absorption may not be complete and additional contraceptive measures should be taken. If vomiting or diarrhea occurs within 3 to 4 hours after taking an active tablet, handle this as a missed tablet [see FDA-Approved Patient Labeling].
The timing of initiation of dosing with Tri-Previfem® for acne should follow the guidelines for use of Tri-Previfem® as an oral contraceptive. Consult the DOSAGE AND ADMINISTRATION section (2.1) for instructions.

Do not prescribe Previfem® or Tri-Previfem® to women who are known to have the following conditions:
Impaired Liver Function
Do not use Previfem® or Tri-Previfem® 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 Previfem® or Tri-Previfem® if jaundice develops.
Liver Tumors
Previfem® and Tri-Previfem® 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 Previfem® or Tri-Previfem® prior to starting therapy with the combination drug regimen ombitasvir/paritaprevir/ritonavir, with or without dasabuvir [see Contraindications (4)]. Previfem® or Tri-Previfem® can be restarted approximately 2 weeks following completion of treatment with the Hepatitis C combination drug regimen.
Previfem® and Tri-Previfem® 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 Previfem® and Tri-Previfem® 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 Previfem® or Tri-Previfem®. 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 Previfem® or Tri-Previfem® develops new headaches that are recurrent, persistent, or severe, evaluate the cause and discontinue Previfem® or Tri-Previfem® if indicated.
Consider discontinuation of Previfem® or Tri-Previfem® 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.
In clinical trials of norgestimate and ethinyl estradiol tablets 0.25 mg/0.035 mg and norgestimate and ethinyl estradiol tablets 0.18 mg/0.035 mg, 0.215 mg/0.035 mg, 0.25 mg/0.035 mg, the frequency and duration of breakthrough bleeding and/or spotting was assessed in 1,647 patients (21,275 evaluable cycles) and 4,826 patients (35,546 evaluable cycles), respectively. A total of 100 (7.5%) women discontinued norgestimate and ethinyl estradiol tablets 0.25 mg/0.035 mg and 231 (4.8%) women discontinued norgestimate and ethinyl estradiol tablets 0.18 mg/0.035 mg, 0.215 mg/0.035 mg, 0.25 mg/0.035 mg, at least in part, due to bleeding or spotting. Based on data from the clinical trials, 14-34% of women using norgestimate and ethinyl estradiol tablets 0.25 mg/0.035 mg experienced unscheduled bleeding per cycle in the first year; for norgestimate and ethinyl estradiol tablets 0.18 mg/0.035 mg, 0.215 mg/0.035 mg, 0.25 mg/0.035 mg, the respective numbers were 13-38%. The percent of women who experienced breakthrough/unscheduled bleeding tended to decrease over time.
Amenorrhea and Oligomenorrhea
Women who use Previfem® or Tri-Previfem® may experience amenorrhea. Some women may experience amenorrhea or oligomenorrhea after discontinuation of COCs, especially when such a condition was pre-existent.
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 epidemiological 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 Previfem® or Tri-Previfem® 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 Previfem® or Tri-Previfem® if depression recurs to a serious degree.
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.
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.
The following serious adverse reactions with the use of COCs are discussed elsewhere in labeling:
Adverse reactions commonly reported by COC users are:
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 rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice.
Norgestimate and Ethinyl Estradiol Tablets 0.25 mg/0.035 mg:
The safety of norgestimate and ethinyl estradiol tablets 0.25 mg/0.035 mg was evaluated in 1,647 healthy women of child-bearing potential who participated in 3 clinical trials and received at least 1 dose of norgestimate and ethinyl estradiol tablets 0.25 mg/0.035 mg for contraception. Two trials were randomized active-controlled trials and 1 was an uncontrolled open-label trial. In all 3 trials, subjects were followed for up to 24 cycles.

Norgestimate and Ethinyl Estradiol Tablets 0.18 mg/0.035 mg, 0.215 mg/0.035 mg, 0.25 mg/0.035 mg:
The safety of norgestimate and ethinyl estradiol tablets 0.18 mg/0.035 mg, 0.215 mg/0.035 mg, 0.25 mg/0.035 mg was evaluated in 4,826 healthy women of child-bearing potential who participated in 6 clinical trials and received at least 1 dose of norgestimate and ethinyl estradiol tablets 0.18 mg/0.035 mg, 0.215 mg/0.035 mg, 0.25 mg/0.035 mg for contraception. Two trials were randomized active-controlled trials and 4 were uncontrolled open-label trials. In 3 trials, subjects were followed for up to 24 cycles; in 2 trials, subjects were followed for up to 12 cycles; and in 1 trial, subjects were followed for up to 6 cycles.
Common Adverse Reactions (≥ 2% of subjects): The most common adverse reactions reported by at least 2% of the 4,826 women were the following in order of decreasing incidence: headache/migraine (33.6%), breast issues (including breast pain, enlargement, and discharge) (8.0%), vaginal infection (7.1%), abdominal/gastrointestinal pain (5.6%), mood disorders (including mood alteration and depression) (3.8%), genital discharge (3.2%), and changes in weight (including weight fluctuation, increased or decreased) (2.5%).
Adverse Reactions Leading to Study Discontinuation: Over the trials, between 9 to 27% of subjects discontinued the trial due to an adverse reaction. The most common adverse reactions (≥1%) leading to discontinuation were: metrorrhagia (4.3%), nausea/vomiting (2.8%), headache/migraine (2.4%), mood disorders (including depression and mood altered) (1.1%), and weight increased (1.1%).
Serious Adverse Reactions: breast cancer (1 subject), carcinoma of the cervix in situ (1 subject), hypertension (1 subject), and migraine (2 subjects).
The following additional adverse drug reactions have been reported from worldwide postmarketing experience with norgestimate/ethinyl estradiol. Because these reactions are reported voluntarily 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.
No drug-drug interaction studies were conducted with norgestimate and ethinyl estradiol tablets.
Substances decreasing the plasma concentrations 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 ethinyl estradiol (EE) increase AUC values for EE by approximately 20-25%. Ascorbic acid and acetaminophen may increase plasma EE concentrations, possibly by inhibition of conjugation. CYP3A4 inhibitors such as itraconazole, voriconazole, 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., boceprevir and telaprevir]) or with non-nucleoside reverse transcriptase inhibitors (decrease [e.g., nevirapine] or increase [e.g., etravirine]).
The use of contraceptive steroids may influence the results of certain laboratory tests, such as coagulation factors, lipids, glucose tolerance, and binding proteins.
Do not co-administer Previfem® or Tri-Previfem® with HCV drug combinations containing ombitasvir/paritaprevir/ritonavir, with or without dasabuvir, due to potential for ALT elevations [see Warnings and Precautions (5.3)].
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 administer 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 norgestimate and ethinyl estradiol tablets have been established in women of reproductive age. Efficacy is expected to be the same for post-pubertal adolescents under the age of 18 and for users 18 years and older. Use of this product before menarche is not indicated.
There was no significant difference between norgestimate and ethinyl estradiol tablets 0.18 mg/0.035 mg, 0.215 mg/0.035 mg, 0.25 mg/0.035 mg and placebo in mean change in total lumbar spine (L1-L4) and total hip bone mineral density between baseline and Cycle 13 in 123 adolescent females with anorexia nervosa in a double-blind, placebo-controlled, multicenter, one-year treatment duration clinical trial for the Intent To Treat (ITT) population.
Norgestimate and Ethinyl Estradiol Tablets have not been studied in postmenopausal women and are not indicated in this population.
The pharmacokinetics of norgestimate and ethinyl estradiol tablets 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)].
There have been no reports of serious ill effects from overdosage of oral contraceptives, including ingestion by children. Overdosage may cause withdrawal bleeding in females and nausea.
Each of the following products is a combination oral contraceptive containing the progestational compound norgestimate and the estrogenic compound ethinyl estradiol. Norgestimate is designated as (18,19-Dinor-17-pregn-4-en-20-yn-3-one,17-(acetyloxy)-13-ethyl-, oxime,(17α)-(+)-) and ethinyl estradiol is designated as (19-nor-17α-pregna,1,3,5(10)-trien-20-yne-3,17-diol).
Previfem®
Each active blue tablet contains 0.25 mg of norgestimate and 0.035 mg of ethinyl estradiol. Inactive ingredients include FD&C Blue No. 1 HT Aluminum Lake, hypromellose, lactose monohydrate, magnesium stearate, polyethylene glycol, and pregelatinized starch.
Each light-green placebo tablet contains only inert ingredients, as follows: FD&C Blue No. 2, hypromellose, iron oxide yellow, lactose monohydrate, magnesium stearate, polyethylene glycol, and pregelatinized starch.
Tri-Previfem®
Each active white tablet contains 0.18 mg of norgestimate and 0.035 mg of ethinyl estradiol. Inactive ingredients include hypromellose, lactose monohydrate, magnesium stearate, polyethylene glycol, and pregelatinized starch.
Each active light-blue tablet contains 0.215 mg of norgestimate and 0.035 mg of ethinyl estradiol. Inactive ingredients include FD&C Blue No. 1 Aluminum Lake, hypromellose, lactose monohydrate, magnesium stearate, polyethylene glycol, and pregelatinized starch.
Each active blue tablet contains 0.25 mg of norgestimate and 0.035 mg of ethinyl estradiol. Inactive ingredients include FD&C Blue No. 1 Aluminum Lake, hypromellose, lactose monohydrate, magnesium stearate, polyethylene glycol, and pregelatinized starch.
Each light-green placebo tablet contains only inert ingredients, as follows: FD&C Blue No. 2, hypromellose, iron oxide yellow, lactose monohydrate, magnesium stearate, polyethylene glycol, and pregelatinized starch.
No specific pharmacodynamic studies were conducted with norgestimate and ethinyl estradiol tablets.
Absorption
Norgestimate (NGM) and EE are rapidly absorbed following oral administration. NGM is rapidly and completely metabolized by first pass (intestinal and/or hepatic) mechanisms to norelgestromin (NGMN) and norgestrel (NG), which are the major active metabolites of norgestimate.
Peak serum concentrations of NGMN and EE are generally reached by 2 hours after administration of norgestimate and ethinyl estradiol tablets. Accumulation following multiple dosing of the 250 mcg NGM / 35 mcg EE dose is approximately 2-fold for NGMN and EE compared with single dose administration. The pharmacokinetics of NGMN is dose-proportional following NGM doses of 180 mcg to 250 mcg. Steady-state concentration of EE is achieved by Day 7 of each dosing cycle. Steady-state concentrations of NGMN and NG are achieved by Day 21. Non-linear accumulation (approximately 8 fold) of NG is observed as a result of high-affinity binding to SHBG, which limits its biological activity (Table 3).

Food Effect
The effect of food on the pharmacokinetics of norgestimate and ethinyl estradiol tablets has not been studied.
Distribution
NGMN and NG are highly bound (>97%) to serum proteins. NGMN is bound to albumin and not to SHBG, while NG is bound primarily to SHBG. EE is extensively bound (>97%) to serum albumin and induces an increase in the serum concentrations of SHBG.
Metabolism
NGM is extensively metabolized by first-pass mechanisms in the gastrointestinal tract and/or liver. NGM’s primary active metabolite is NGMN. Subsequent hepatic metabolism of NGMN occurs and metabolites include NG, which is also active, and various hydroxylated and conjugated metabolites. Although NGMN and its metabolites inhibit a variety of P450 enzymes in human liver microsomes, under the recommended dosing regimen, the in vivo concentrations of NGMN and its metabolites, even at the peak serum levels, are relatively low compared to the inhibitory constant (Ki). EE is also metabolized to various hydroxylated products and their glucuronide and sulfate conjugates.
Excretion
The metabolites of NGMN and EE are eliminated by renal and fecal pathways. Following administration of 14C-norgestimate, 47% (45-49%) and 37% (16-49%) of the administered radioactivity was eliminated in the urine and feces, respectively. Unchanged NGM was not detected in the urine. In addition to 17-deacetyl norgestimate, a number of metabolites of NGM have been identified in human urine following administration of radiolabeled NGM. These include 18, 19-Dinor-17-pregn-4-en-20-yn-3-one,17-hydroxy-13-ethyl,(17α)-(-);18,19-Dinor-5β 17-pregnan-20-yn,3α,17β-dihydroxy-13-ethyl,(17α), various hydroxylated metabolites and conjugates of these metabolites.

Do birth control pills cause cancer?
Birth control pills do not seem to cause breast cancer. However, if you have breast cancer now, or have had it in the past, do not use birth control pills 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 if I want to become pregnant?
You may stop taking the pill whenever you wish. Consider a visit with your healthcare provider for a pre-pregnancy checkup before you stop taking the pill.
What should I know about my period when taking Previfem® or Tri-Previfem®?
Your periods may be lighter and shorter than usual. Some women may miss a period. Irregular vaginal bleeding or spotting may happen while you are taking Previfem® or Tri-Previfem®, especially during the first few months of use. This usually is not a serious problem. It is important to continue taking your pills on a regular schedule to prevent a pregnancy.

Important Information about taking Previfem® or Tri-Previfem®
Before you start taking Previfem® or Tri-Previfem®:
When should I start taking Previfem® or Tri-Previfem®?
If you start taking Previfem® or Tri-Previfem® and you have not used a hormonal birth control method before:
If you start taking Previfem® or Tri-Previfem® and you are switching from another birth control pill:
If you start taking Previfem® or Tri-Previfem® and previously used a vaginal ring or transdermal patch:
If you start taking Previfem® or Tri-Previfem® and you are switching from a progestin-only method such as an implant or injection:
If you start taking Previfem® or Tri-Previfem® and you are switching from an intrauterine device or system (IUD or IUS):
Keep a calendar to track your period:
If this is the first time you are taking birth control pills, read, “When should I start taking Previfem® or Tri-Previfem®?” above. Follow these instructions for either a Sunday Start or a Day 1 Start.
Sunday Start:
You will use a Sunday Start if your healthcare provider told you to take your first pill on a Sunday.
Day 1 Start:
You will use a Day 1 Start if your doctor told you to take your first pill (Day 1) on the first day of your period.
Previfem® and Tri-Previfem® come in a blister pack pill dispenser. Read the instructions below for using your blister pack pill dispenser.
Your blister package consists of three parts, the calendar label, the sleeve and the blister pack containing 28 individually sealed pills. Note that the pills are arranged in four numbered rows of 7 pills, with the pre-printed days of the week printed above them. Refer to the sample of the blister pack below:
Previfem® consists of 21 blue “active” birth control pills and 7 light green “reminder” pills.
Tri-Previfem® consists of 7 white “active” pills, 7 light-blue “active” pills, 7 blue “active” pills and 7 light green “reminder” pills.
There are two ways to start taking birth-control pills, Sunday Start or Day 1 Start. Your healthcare professional will tell you which to use.
How to use Blister Cards for the 28 tablets
1. If Sunday Start, discard the sticker and take the first active pill on the first Sunday after your menstrual period begins. Due to the potential risk of becoming pregnant, use additional non-hormonal contraception (such as condom and spermicide) for the first seven days of your first cycle pack of Previfem® or Tri-Previfem®.
2. If Day 1 Start, pick the Days of the Week Sticker that starts the first day of your period. (This is the day you begin bleeding or spotting, even if it is midnight when bleeding begins.)When you have picked the right sticker, throw away the others and place the sticker on the blister card over the preprinted days of the week and make sure it lines up with the pills.
3. Remove the first pill by pushing down on the pill. Swallow the pill. You will take 1 pill every day, at the same time each day. Wait 24 hours to take your next pill. Continue to take 1 pill each day until all the pills have been taken.
4. It is important to take the correct pill each day and not miss any pills. To help you remember, take your pill at the same time as another daily activity, like turning off your alarm clock or brushing your teeth.
5. After taking the last pill, start a new blister pack the very next day, no matter when your next period starts.
6. Take the pills in each new package as before. Start with the pill on row #1 and take one pill each day, left to right, until the last pill has been taken.
Three Ways to Remember in What Order to Take the Pills
1. Follow the sticker with the days of the week (placed above the pills).
2. Always go from left to right.
3. Always finish all your pills.
What should I do if I miss any Previfem® or Tri-Previfem® pills?
If you miss 1 pill in Weeks 1, 2, or 3, follow these steps:
If you miss 2 pills in Week 1 or Week 2 of your pack, follow these steps:
If you miss 2 pills in a row in Week 3, or you miss 3 or more pills in a row during Weeks 1, 2, or 3 of the pack, follow these steps:
