Medically reviewed on December 1, 2017
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)].
Indications and Usage for Tri-Linyah
Tri-Linyah Tablets are indicated for use by females of reproductive potential to prevent pregnancy [see Clinical Studies (14)].
Tri-Linyah 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. Tri-Linyah should be used for the treatment of acne only if the patient desires an oral contraceptive for birth control [see Clinical Studies (14)].
Tri-Linyah Dosage and Administration
How to Start Tri-Linyah
Tri-Linyah is dispensed in 28-tablet blister [see How Supplied/Storage and Handling (16)]. Tri-Linyah may be started using either a Day 1 start or a Sunday start (see Table 1). The plastic compact is pre-set for a Sunday start. Day 1 Start day-label stickers are available. 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.
How to Take Tri-Linyah
- After a first-trimester abortion or miscarriage, Tri-Linyah may be started immediately. An additional method of contraception is not needed if Tri-Linyah is started immediately.
- If Tri-Linyah is not started within 5 days after termination of the pregnancy, the patient should use additional non-hormonal contraception (such as condoms and spermicide) for the first seven days of her first cycle pack of Tri-Linyah.
- Do not start until 4 weeks after a second-trimester abortion or miscarriage, due to the increased risk of thromboembolic disease. Start Tri-Linyah, following the instructions in Table 1 for Day 1 or Sunday start, as desired. If using Sunday start, use additional non-hormonal contraception (such as condoms and spermicide) for the first seven days of the patient's first cycle pack of Tri-Linyah.[see Contraindications (4), Warnings and Precautions (5.1), and FDA-Approved Patient Labeling.]
- Do not start until 4 weeks after delivery, due to the increased risk of thromboembolic disease. Start contraceptive therapy with Tri-Linyah following the instructions in Table 1 for women not currently using hormonal contraception.
- Tri-Linyah is not recommended for use in lactating women [see Use in Specific Populations(8.3) ].
- If the woman has not yet had a period postpartum, consider the possibility of ovulation and conception occurring prior to use of Tri-Linyah. [See Contraindications(4) , Warnings and Precautions(5.1) , Use in Specific Populations (8.1and8.3), and FDA-Approved Patient Labeling].
If the patient starts pill-taking on Sunday,the first active pill should be taken on the first Sunday after the patient's menstrual period begins.Remove the first active pill at the top of the dispenser (Sunday) by pressing the pill through the blister foil.
If the patient will start pill-taking on "Day 1,"place a day-label sticker on the compact which starts with the day of the week the patient will take the first pill.Remove the first active pill at the top of the dispenser(Day 1)by pressing the pill through the blister foil.
Advice in Case of Gastrointestinal Disturbances
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].
Tri-Linyah Use for Acne
The timing of initiation of dosing with Tri-Linyah for acne should follow the guidelines for use of Tri-Linyah as an oral contraceptive. Consult the DOSAGE AND ADMINISTRATION section (2.1) for instructions.

- Undiagnosed abnormal uterine bleeding[see Warnings and Precautions (5.8)]
- Pregnancy, because there is no reason to use COCs during pregnancy[ see Warnings and Precautions (5.9)and Use in Specific Populations (8.1)]
- Breast cancer or other estrogen- or progestin-sensitive cancer, now or in the past[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)]
Warnings and Precautions
Thrombotic Disorders and Other Vascular Problems
- Stop Tri-Linyah if an arterial thrombotic event or venous thromboembolic (VTE) event occurs.
- Stop Tri-Linyah if there is unexplained loss of vision, proptosis, diplopia, papilledema, or retinal vascular lesions. Evaluate for retinal vein thrombosis immediately[see Adverse Reactions (6.2)] .
- If feasible, stop Tri-Linyah at least 4 weeks before and through 2 weeks after major surgery or other surgeries known to have an elevated risk of VTE as well as during and following prolonged immobilization.
- Start Tri-Linyah 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 cases per 10,000 woman-years. The risk of VTE is highest during the first year of use of COCs and when restarting hormonal contraception after a break of 4 weeks or longer. The risk of thromboembolic disease due to COCs gradually disappears after 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). This risk increases with age, particularly in women over 35 years of age who smoke.
- Use COCs with caution in women with cardiovascular disease risk factors.
Do not use Tri-Linyah 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 Tri-Linyah if jaundice develops.
Tri-Linyah is 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.
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 Tri-Linyah prior to starting therapy with the combination drug regimen ombitasvir/paritaprevir/ritonavir, with or without dasabuvir [see Contraindications (4)]. Tri-Linyah can be restarted approximately 2 weeks following completion of treatment with the Hepatitis C combination drug regimen.
High Blood Pressure
Tri-Linyah 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 Tri-Linyah 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.
Carbohydrate and Lipid Metabolic Effects
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.
Consider discontinuation of Tri-Linyah in the case of increased frequency or severity of migraine during COC use (which may be prodromal of a cerebrovascular event).
Bleeding Irregularities and Amenorrhea
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.
I In clinical trials of norgestimate and ethinyl estradiol tricycle tablets, 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 231 (4.8%) women discontinued norgestimate and ethinyl estradiol tricycle tablets, at least in part, due to bleeding or spotting. Based on data from the clinical trials, 13-38% of women using norgestimate and ethinyl estradiol tricycle tablets experienced unscheduled bleeding per cycle in the first year. The percent of women who experienced breakthrough/unscheduled bleeding tended to decrease over time.
Amenorrhea and Oligomenorrhea
Women who use Tri-Linyah 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.
COC Use Before or During Early 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 Tri-Linyah 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)].
Carcinoma of the Breast and Cervix
5.11.1 Tri-Linyah is contraindicated in women who currently have or have had breast cancer because breast cancer may be hormonally sensitive [see Contraindications (4)] There is substantial evidence that COCs do not increase the incidence of breast cancer. Although some past studies have suggested that COCs might increase the incidence of breast cancer, more recent studies have not confirmed such findings.
5.11.2 Some studies suggest that COC use has been associated with an increase in the risk of cervical cancer or intraepithelial neoplasia. However, there continues to be controversy about the extent to which such findings may be due to differences in sexual behavior and other factors.
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.
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 Tri-Linyah.
- 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)]
- Irregular uterine bleeding
- Breast tenderness
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 rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice.
The safety of tri-cycle norgestimate and ethinyl estradiol Tablets was evaluated in 4,826 healthy women of child-bearing potential who participated in 6 clinical trials and received at least 1 dose of tri-cycle norgestimate and ethinyl estradiol Tablets 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.
Infections and Infestations: Urinary tract infection;
Neoplasms Benign, Malignant and Unspecified (Incl. Cysts and Polyps): Breast cancer, benign breast neoplasm, hepatic adenoma, focal nodular hyperplasia, breast cyst;
Immune System Disorders: Hypersensitivity;
Metabolism and Nutrition Disorders: Dyslipidemia;
Psychiatric Disorders: Anxiety, insomnia;
Nervous System Disorders: Syncope, convulsion, paresthesia, dizziness;
Eye Disorders: Visual impairment, dry eye, contact lens intolerance;
Ear and Labyrinth Disorders: Vertigo;
Cardiac Disorders: Tachycardia, palpitations;
Vascular Events: Deep vein thrombosis, pulmonary embolism, retinal vascular thrombosis, hot flush;
Arterial Events: Arterial thromboembolism, myocardial infarction, cerebrovascular accident;
Respiratory, Thoracic and Mediastinal Disorders: Dyspnea;
Gastrointestinal Disorders: Pancreatitis, abdominal distension, diarrhea, constipation;

No drug-drug interaction studies were conducted with Tri-Linyah.
Effects of Other Drugs on Combined Oral Contraceptives
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]).
Effects of Combined Oral Contraceptives on Other Drugs
7.2.2 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.
Interference with Laboratory Tests
Concomitant Use with HCV Combination Therapy – Liver Enzyme Elevatio
Do not co-administer Tri-Linyah with HCV drug combinations containing ombitasvir/paritaprevir/ritonavir, with or without dasabuvir, due to potential for ALT elevations [see Warnings and Precautions (5.3)].
USE IN SPECIFIC POPULATIONS
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 Tri-Linyah 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 Tri-Linyah Tablets 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.
The pharmacokinetics of Tri-Linyah 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).]

Tri-Linyah - Clinical Pharmacology
Mechanism of Action
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.
Acne is a skin condition with a multifactorial etiology, including androgen stimulation of sebum production. While the combination of ethinyl estradiol and norgestimate increases sex hormone-binding globulin (SHBG) and decreases free testosterone, the relationship between these changes and a decrease in the severity of facial acne in otherwise healthy women with this skin condition has not been established.
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 Tri-Linyah. 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).
The effect of food on the pharmacokinetics of Tri-Linyah has not been studied.
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.
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.
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,(17 )-(-);18,19-Dinor-5 -17-pregnan-20-yn,3 ,17 -dihydroxy-13-ethyl,(17 ), various hydroxylated metabolites and conjugates of these metabolites.
Carcinogenesis, Mutagenesis, Impairment of Fertility
In four clinical trials with tri-cycle norgestimate and ethinyl estradiol tablets, 4,756 women aged 15 to 41 years were studied for 24 cycles, providing a total of 45,244 cycles of exposure. The racial demographic was about 87-90% Caucasian, 6-10% African-American, with the remainder Asian ( 1%) or Other (2-5%). There were no exclusions on the basis of weight; the weight range for women treated was 80-310 lbs, with a mean weight of about 132 lbs. The pregnancy rate was approximately 1 pregnancy per 100 women-years.
Tri-cycle norgestimate and ethinyl estradiol tablets were evaluated for the treatment of acne vulgaris in two randomized, double-blind, placebo-controlled, multicenter, six- (28 day) cycle studies. Two hundred twenty- one patients received tri-cycle norgestimate and ethinyl estradiol tablets and 234 patients received placebo. Mean age at enrollment for both groups was 28 years. At the end of 6 months, the mean total lesion count changed from 55 to 31 (42% reduction) in patients treated with tri-cycle norgestimate and ethinyl estradiol tablets and from 54 to 38 (27% reduction) in patients similarly treated with placebo. Table 4 summarizes the changes in lesion count for each type of lesion. Based on the investigator's global assessment conducted at the final visit, patients treated with tri-cycle norgestimate and ethinyl estradiol tablets showed a statistically significant improvement in total lesions compared to those treated with placebo.

Patient Counseling Information
Counsel patients about the following information:
- Cigarette smoking increases the risk of serious cardiovascular events from COC use, and that women who are over 35 years old and smoke should not use COCs [see Boxed Warning].
- 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 [see Warnings and Precautions (5.1)].
- Tri-Linyah does not protect against HIV infection (AIDS) and other sexually transmitted infections.
- Tri-Linyah is not to be used during pregnancy; if pregnancy occurs during use of Tri-Linyah instruct the patient to stop further use[see Warnings and Precautions (5.9)] .
- Take one tablet daily by mouth at the same time every day. Instruct patients what to do in the event tablets are missed[see Dosage and Administration (2.2)] .
- Use a back-up or alternative method of contraception when enzyme inducers are used with Tri-Linyah[see Drug Interactions (7.1)] .
- COCs may reduce breast milk production; this is less likely to occur if breastfeeding is well established[see Use in Specific Populations (8.3)] .
- Women who start COCs postpartum, and who have not yet had a period, should use an additional method of contraception until they have taken an active tablet for 7 consecutive days[see Dosage and Administration (2.2)] .
- Amenorrhea may occur. Consider pregnancy in the event of amenorrhea at the time of the first missed period. Rule out pregnancy in the event of amenorrhea in two or more consecutive cycles[see Warnings and Precautions (5.8)] .
(norgestimate and ethinyl estradiol) Tablets
What is the most important information I should know about Tri-Linyah?
Do not use Tri-Linyah if you smoke cigarettes and are over 35 years old.
Smoking increases your risk of serious cardiovascular side effects from hormonal 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 is Tri-Linyah?
Tri-Linyah is a birth control pill (oral contraceptive) used by women to prevent pregnancy.
Tri-Linyah is also used to treat moderate acne vulgaris in females 15 years of age and older, who have no known history of allergies or problems taking birth control pills, and have started their menstrual cycle ("period"). Tri-Linyah should only be used to treat acne in women who want to take birth control pills to prevent pregnancy.
How does Tri-Linyah 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 clinical studies, about 1 out of 100 women may get pregnant during the first year they use Tri-Linyah.
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.
- smoke and are over 35 years of age
- had blood clots in your arms, legs, lungs, or eyes
- had a problem with your blood that makes it clot more than normal
- have certain heart valve problems or irregular heart beat that increases your risk of having blood clots
- had a stroke
- had a heart attack
- have high blood pressure that cannot be controlled by medicine
- have diabetes with kidney, eye, nerve, or blood vessel damage
- have certain kinds of severe migraine headaches with aura, numbness, weakness or changes in vision, or any migraine headaches if you are over 35 years of age
- have liver problems, including liver tumors

right away and talk to your healthcare provider. Use non-hormonal contraception when you stop taking Tri-Linyah.
What should I tell my healthcare provider before taking Tri-Linyah?
Tell your healthcare provider if you:
- are pregnant or think you may be pregnant
- are depressed now or have been depressed in the past
- had yellowing of your skin or eyes (jaundice) caused by pregnancy (cholestasis of pregnancy)
- are breastfeeding or plan to breastfeed. Tri-Linyah may decrease the amount of breast milk you make. A small amount of the hormones in Tri-Linyah may pass into your breast milk. Talk to your healthcare provider about the best birth control method for you while breastfeeding.
Tri-Linyah may affect the way other medicines work, and other medicines may affect how well Tri-Linyah works.
Know the medicines you take. Keep a list of them to show your healthcare provider and pharmacist when you get a new medicine.

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 Tri-Linyah?
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 Tri-Linyah, 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.

Start the first pill of your next pill dispenser the day after finishing your current pill dispenser. This will be 1 day earlier than originally scheduled. Continue on your new schedule.
