TriNessa

TriNessa is a prescription birth control medication used:

• to prevent pregnancy
• to treat acne in females at least 15 years of age who have started having menstrual periods

Cigarette smoking increases the risk of serious cardiovascular side effects from oral contraceptive use. This risk increases with age and with heavy smoking (15 or more cigarettes per day) and is quite marked in women over 35 years of age. Women who use oral contraceptives such as TriNessa should be strongly advised not to smoke.

TriNessa® is indicated for the prevention of pregnancy in women who elect to use oral contraceptives as a method of contraception.

TriNessa® 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. TriNessa® should be used for the treatment of acne only if the patient desires an oral contraceptive for birth control.

Oral contraceptives are highly effective for pregnancy prevention. Table 2 lists the typical accidental pregnancy rates for users of combination oral contraceptives and other methods of contraception. The efficacy of these contraceptive methods, except sterilization, the IUD, and the Norplant® System, depends upon the reliability with which they are used. Correct and consistent use of methods can result in lower failure rates.

TriNessa® has not been studied for and is not indicated for use in emergency contraception.

In four clinical trials with TriNessa®, a total of 4,756 subjects completed 45,244 cycles, and the use-efficacy pregnancy rate was approximately 1 pregnancy per 100 women-years.

TriNessa® was evaluated for the treatment of acne vulgaris in two randomized, double-blind, placebo-controlled, multicenter, Phase 3, six (28 day) cycle studies. 221 patients received TriNessa® 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 changes from 55 to 31 (42% reduction) in patients treated with TriNessa® and from 54 to 38 (27% reduction) in patients similarly treated with placebo. Table 3 summarizes the changes in lesion count for each type of lesion in the ITT population. Based on the investigator's global assessment conducted at the final visit, patients treated with TriNessa® showed a statistically significant improvement in total lesions compared to those treated with placebo.

The following non-contraceptive health benefits related to the use of combination oral contraceptives are supported by epidemiological studies which largely utilized oral contraceptive formulations containing estrogen doses exceeding 0.035 mg of ethinyl estradiol or 0.05 mg mestranol.73–78

Effects on menses:

• increased menstrual cycle regularity
• decreased blood loss and decreased incidence of iron deficiency anemia
• decreased incidence of dysmenorrhea

Effects related to inhibition of ovulation:

• decreased incidence of functional ovarian cysts
• decreased incidence of ectopic pregnancies

Other effects:

• decreased incidence of fibroadenomas and fibrocystic disease of the breast
• decreased incidence of acute pelvic inflammatory disease
• decreased incidence of endometrial cancer
• decreased incidence of ovarian cancer

TriNessa® is available in a blister card (NDC 52544-248-28) with a tablet dispenser (unfilled).

This product (like all oral contraceptives) does not protect against HIV infection (AIDS) and other sexually transmitted diseases.

Oral contraceptives, also known as "birth control pills" or "the pill," are taken to prevent pregnancy. When taken correctly to prevent pregnancy, oral contraceptives have a failure rate of approximately 1% per year (1 pregnancy per 100 women per year of use) when used without missing any pills. The typical failure rate is approximately 5% per year (5 pregnancies per 100 women per year of use) when women who miss pills are included. For most women oral contraceptives are also free of serious or unpleasant side effects. However, forgetting to take pills considerably increases the chances of pregnancy.

TriNessa® may also be taken to treat moderate acne in females at least 15 years of age, who have started having menstrual periods, are able to take the pill and want to use the pill for birth control.

For the majority of women, oral contraceptives can be taken safely. But there are some women who are at high risk of developing certain serious diseases that can be fatal or may cause temporary or permanent disability. The risks associated with taking oral contraceptives increase significantly if you:

• smoke
• have high blood pressure, diabetes, high cholesterol
• have or have had clotting disorders, heart attack, stroke, angina pectoris, cancer of the breast or sex organs, jaundice or malignant or benign liver tumors.

Although cardiovascular disease risks may be increased with oral contraceptive use after age 40 in healthy, non-smoking women (even with the newer low-dose formulations), there are also greater potential health risks associated with pregnancy in older women.

You should not take the pill if you suspect you are pregnant or have unexplained vaginal bleeding.

Do not use TriNessa® 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 combination oral contraceptives, including death from heart attack, blood clots or stroke. This risk increases with age and the number of cigarettes you smoke.

Most side effects of the pill are not serious. The most common side effects are nausea, vomiting, bleeding between menstrual periods, weight gain, breast tenderness, and difficulty wearing contact lenses. These side effects, especially nausea and vomiting, may subside within the first three months of use.

The serious side effects of the pill occur very infrequently, especially if you are in good health and are young. However, you should know that the following medical conditions have been associated with or made worse by the pill:

1. Blood clots in the legs (thrombophlebitis), lungs (pulmonary embolism), stoppage or rupture of a blood vessel in the brain (stroke), blockage of blood vessels in the heart (heart attack or angina pectoris) or other organs of the body. As mentioned above, smoking increases the risk of heart attacks and strokes and subsequent serious medical consequences.
2. In rare cases, oral contraceptives can cause benign but dangerous liver tumors. These benign liver tumors can rupture and cause fatal internal bleeding. In addition, some studies report an increased risk of developing liver cancer. However, liver cancers are rare.
3. High blood pressure, although blood pressure usually returns to normal when the pill is stopped.

The symptoms associated with these serious side effects are discussed in the detailed leaflet given to you with your supply of pills. Notify your healthcare professional if you notice any unusual physical disturbances while taking the pill. In addition, drugs such as rifampin, bosentan, as well as some seizure medicines and herbal preparations containing St. John's wort (Hypericum perforatum) may decrease oral contraceptive effectiveness.

Oral contraceptives may interact with lamotrigine (LAMICTAL®), a seizure medicine used for epilepsy. This may increase the risk of seizures so your healthcare professional may need to adjust the dose of lamotrigine.

Various studies give conflicting reports on the relationship between breast cancer and oral contraceptive use. Oral contraceptive use may slightly increase your chance of having breast cancer diagnosed, particularly after using hormonal contraceptives at a younger age. After you stop using hormonal contraceptives, the chances of having breast cancer diagnosed begin to go back down. You should have regular breast examinations by a healthcare professional and examine your own breasts monthly. Tell your healthcare professional if you have a family history of breast cancer or if you have had breast nodules or an abnormal mammogram. Women who currently have or have had breast cancer should not use oral contraceptives because breast cancer is usually a hormone-sensitive tumor.

Some studies have found an increase in the incidence of cancer of the cervix in women who use oral contraceptives. However, this finding may be related to factors other than the use of oral contraceptives. There is insufficient evidence to rule out the possibility that the pill may cause such cancers.

Taking the combination pill provides some important non-contraceptive benefits. These include less painful menstruation, less menstrual blood loss and anemia, fewer pelvic infections, and fewer cancers of the ovary and the lining of the uterus.

Be sure to discuss any medical condition you may have with your healthcare professional. Your healthcare professional will take a medical and family history before prescribing oral contraceptives and will examine you. The physical examination may be delayed to another time if you request it and the healthcare professional believes that it is a good medical practice to postpone it. You should be reexamined at least once a year while taking oral contraceptives. Your pharmacist should have given you the detailed patient information labeling which gives you further information which you should read and discuss with your healthcare professional.

HOW TO TAKE THE PILL

IMPORTANT POINTS TO REMEMBER

BEFORE YOU START TAKING YOUR PILLS:

1. BE SURE TO READ THESE DIRECTIONS:
   Before you start taking your pills.
   Anytime you are not sure what to do.
2. THE RIGHT WAY TO TAKE THE PILL IS TO TAKE ONE PILL EVERY DAY AT THE SAME TIME.
   If you miss pills you could get pregnant. This includes starting the pack late.
   The more pills you miss, the more likely you are to get pregnant.
3. MANY WOMEN HAVE SPOTTING OR LIGHT BLEEDING, OR MAY FEEL SICK TO THEIR STOMACH DURING THE FIRST 1–3 PACKS OF PILLS. If you feel sick to your stomach or have spotting or light bleeding, do not stop taking the pill. The problem will usually go away. If it doesn't go away, check with your healthcare professional.
4. MISSING PILLS CAN ALSO CAUSE SPOTTING OR LIGHT BLEEDING, even when you make up these missed pills.
   On the days you take 2 pills to make up for missed pills, you could also feel a little sick to your stomach.
5. IF YOU HAVE VOMITING OR DIARRHEA, OR IF YOU TAKE SOME MEDICINES, your pills may not work as well.
   Use a back-up method (such as a condom or spermicide) until you check with your healthcare professional.
6. IF YOU HAVE TROUBLE REMEMBERING TO TAKE THE PILL, talk to your healthcare professional about how to make pill-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 professional.

BEFORE YOU START TAKING YOUR PILLS

1. DECIDE WHAT TIME OF DAY YOU WANT TO TAKE YOUR PILL.
   It is important to take it at about the same time every day.
2. LOOK AT YOUR PILL PACK
   The pill pack has 21 "active" pills (with hormones) to take for 3 weeks. This is followed by 1 week of "reminder" dark green pills (without hormones).
   There are 7 white "active" pills, 7 light blue "active" pills, 7 blue "active" pills, and 7 dark green "reminder" pills.
3. ALSO FIND: 1) where on the pack to start taking pills, 2) in what order to take the pills.
4. BE SURE YOU HAVE READY AT ALL TIMES:
   ANOTHER KIND OF BIRTH CONTROL (such as a condom or spermicide) to use as a back-up method in case you miss pills.
   AN EXTRA, FULL PILL PACK.

WHEN TO START THE FIRST PACK OF PILLS

You have a choice of which day to start taking your first pack of pills. TriNessa® is available in a blister card with a tablet dispenser which is preset for a Sunday Start. Day 1 Start is also provided. Decide with your healthcare professional which is the best day for you. Pick a time of day that will be easy to remember.

Sunday Start:

Take the first white "active" pill of the first 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.

Use another method of birth control such as a condom or 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).

Day 1 Start:

Take the first white "active" pill of the first pack during the first 24 hours of your period.

You will not need to use a back-up method of birth control, since you are starting the pill at the beginning of your period.

WHAT TO DO DURING THE MONTH

WHAT TO DO IF YOU MISS PILLS

If you MISS 1 white, light blue, or blue "active" pill:

1. Take it as soon as you remember. Take the next pill at your regular time. This means you may take 2 pills in 1 day.
2. You do not need to use a back-up birth control method if you have sex.

If you MISS 2 white or light blue "active" pills in a row in WEEK 1 OR WEEK 2 of your pack:

1. Take 2 pills on the day you remember and 2 pills the next day.
2. Then take 1 pill a day until you finish the pack.
3. You COULD BECOME PREGNANT if you have sex in the 7 days after you miss pills. You MUST use another birth control method (such as a condom or spermicide) as a back-up method for those 7 days.

If you MISS 2 blue "active" pills in a row in THE 3RD WEEK:

1. If you are a Sunday Starter:
   Keep taking 1 pill every day until Sunday. On Sunday, THROW OUT the rest of the pack and start a new pack of pills that same day.
   If you are a Day 1 Starter:
   THROW OUT the rest of the pill pack and start a new pack that same day.
2. You may not have your period this month but this is expected. However, if you miss your period 2 months in a row, call your healthcare professional because you might be pregnant.
3. You COULD BECOME PREGNANT if you have sex in the 7 days after you miss pills. You MUST use another birth control method (such as a condom or spermicide) as a back-up method for those 7 days.

If you MISS 3 OR MORE white, light blue, or blue "active" pills in a row (during the first 3 weeks):

1. If you are a Sunday Starter:
   Keep taking 1 pill every day until Sunday. On Sunday, THROW OUT the rest of the pack and start a new pack of pills that same day.
   If you are a Day 1 Starter:
   THROW OUT the rest of the pill pack and start a new pack that same day.
   
2. You may not have your period this month but this is expected. However, if you miss your period 2 months in a row, call your healthcare professional because you might be pregnant.
3. You COULD BECOME PREGNANT if you have sex in the 7 days after you miss pills. You MUST use another birth control method (such as a condom or spermicide) as a back-up method for those 7 days.

A REMINDER:

If you forget any of the 7 dark green "reminder" pills in WEEK 4:

THROW AWAY the pills you missed.

Keep taking 1 pill each day until the pack is empty.

You do not need a back-up method.

FINALLY, IF YOU ARE STILL NOT SURE WHAT TO DO ABOUT THE PILLS YOU HAVE MISSED:

Use a BACK-UP METHOD anytime you have sex.

KEEP TAKING ONE "ACTIVE" PILL EACH DAY until you can reach your healthcare professional.

INSTRUCTIONS FOR USE

1. Open the compact. Place the blister into the compact, with the tablets facing up, so that the V notch in the blister card matches up with the V-shaped post at the top of the compact. Press down firmly on each edge of the blister card and make sure that the edge of the card is firmly seated under each of the nibs inside the compact (see picture).
   There are 7 white "active" pills, 7 light blue "active" pills, 7 blue "active" pills and 7 dark green "reminder" pills.

2. If you are to start pill taking on Sunday, take your first white pill on the first Sunday after your menstrual period begins. If your period begins on Sunday, take your first pill that day. Remove the first pill at the top of the dispenser (Sunday) by pressing the pill through the hole in the bottom of the dispenser.
3. If you are to start pill taking on a day other than Sunday, the enclosed calendar label has been provided and will be placed over the calendar in the center of the blister card. To put the label in place, identify your correct starting day, locate that day printed in blue on the label, and line your blue starting day up with the first white pill which is directly under the V notch at the top of the dispenser. Remove the label from the backing. Press the center of the label down onto the center of the printed calendar. Remove that white pill by pressing the pill through the hole in the bottom of the dispenser.
4. Continue taking one pill daily, clockwise, until no pills remain in the outer ring.
5. The next day take the dark green pill from the inner ring that corresponds with the day of the week it happens to be. Take a dark green pill each day until all seven pills are taken. During this time your period should begin.
6. After you have taken all the dark green pills, begin a new blister card (see Step 1 above in "Instructions for Use") and take the first white "active" pill on the next day, even if your period is not yet over.

General

Women taking oral contraceptive combinations experience several non-contraceptive health benefits. These benefits include protection against two malignant neoplasms (endometrial carcinoma and ovarian cancer). In addition, use of oral contraceptive combinations decreases the frequency of benign breast tumors, decreases the risk of ovarian cysts, decreases the risk of ectopic pregnancy, increases menstrual regularity, decreases the incidence of iron deficiency anemia, decreases the incidence of dysmenorrhea, and decreases the incidence of pelvic inflammatory disease.[Ref]

A number of studies have suggested that use of oral contraceptives decreases the risk of ovarian cancer. Specifically, the risk of epithelial ovarian cancers is decreased by 40%. The protection against ovarian cancer may last for 10 to 15 years after discontinuation of oral contraceptives. After long term use (12 years), the risk of ovarian cancer is decreased by as much as 80%.

The risk of endometrial cancer is decreased by approximately 50%. Protection may last for 15 years after discontinuation and may be greatest for nulliparous women who may be at higher risk for endometrial carcinoma than other women.

The incidence of hospitalization for pelvic inflammatory disease is approximately 50% lower in women taking oral contraceptives. The reason for the decrease in the frequency (or severity) of pelvic inflammatory disease in women taking oral contraceptives has not been fully elucidated.

Some recent studies have suggested that the decrease in frequency of functional ovarian cysts reported with some older formulations may not occur in women taking newer low dose formulations.

One recent study (The Nurses' Health Study) has suggested that long term use of oral contraceptives is safe and does not adversely affect long term risk for mortality.[Ref]

Gastrointestinal

A relatively common gastrointestinal side effect is nausea, which occurs in approximately 10% of treated women and may be more frequent during the first cycles of therapy. Some early reports suggested an association between oral contraceptive use and gallbladder disease.[Ref]

Cases of oral contraceptive-induced esophageal ulceration and geographic tongue have been reported rarely.

More recent studies have suggested that the risk of gallbladder disease is minimal.[Ref]

Oncologic

The World Health Organization committee also noted that some studies "have found a weak association between long-term use of oral contraceptives and breast cancer diagnosed before the age of 36, and perhaps up to the age 45....It is unclear whether this observed association is attributable to bias, the development of new cases of cancer, or accelerated growth of existing cancers."

The World Health Organization committee further concluded that there is no increased risk of breast cancer in women over the age of 45 who have previously taken oral contraceptives. In addition, studies suggest that use of oral contraceptives does not place specific groups of women (like those with a family history of breast cancer) at higher or lower risk, and variations in the hormonal content of oral contraceptives do not influence the risk of breast cancer.

In general, studies evaluating the potential risk of cervical cancer in patients taking oral contraceptives have been complicated by the large number of confounding factors which make investigations into the epidemiology of this neoplasm difficult. Some studies have suggested that women taking oral contraceptives are at increased risk of dysplasia, epidermoid carcinoma, and adenocarcinoma of the cervix. However, other studies have not found such an association.[Ref]

A number of studies have examined a possible relationship between the use of oral contraceptives and the development of breast cancer. Many of the studies have reported conflicting results. A committee of the World Health Organization evaluated these studies and the risks of breast cancer and concluded that: "Numerous studies have found no overall association between oral contraceptive use and risk of breast cancer." In addition, the same committee also examined a possible relationship between oral contraceptive use and neoplasms of the uterine cervix and concluded that: "There are insufficient data to draw any firm conclusions regarding the effects of combined oral contraceptives on the risk of cervical adenocarcinoma."[Ref]

Cardiovascular

Oral contraceptive combinations have been studied extensively for oncologic side effects. A number of studies have examined a possible relationship between the use of oral contraceptives and the development of breast cancer. Many of the studies have reported conflicting results. A committee of the World Health Organization evaluated these studies and the risks of breast cancer and concluded that: "Numerous studies have found no overall association between oral contraceptive use and risk of breast cancer." In addition, the same committee also examined a possible relationship between oral contraceptive use and neoplasms of the uterine cervix and concluded that: "There are insufficient data to draw any firm conclusions regarding the effects of combined oral contraceptives on the risk of cervical adenocarcinoma."[Ref]

Detailed information concerning the effects of oral contraceptive therapy on lipid metabolism is available in the Endocrine paragraph of this side effect monograph.

Some early investigations of women taking high dose estrogen combinations (50 mcg or more of ethinyl estradiol or equivalent daily) suggested that such women may be at increased risk of cardiovascular complications (myocardial infarction, stroke, and vascular thrombosis, including venous thromboembolism). However, more recent large investigations of women taking low dose estrogen combinations have suggested that oral contraceptive use is not associated with an increased risk of serious cardiovascular complications in healthy non smoking women up to the age of 45. (For women aged 35 to 44 who smoke or who have preexisting systemic diseases that may affect the cardiovascular system, use of oral contraceptives is not recommended.)

However, some investigators have suggested that even the new low dose products may result in adverse effects on lipid metabolism and should prompt careful review of a woman's cardiovascular risk factors before a decision to use oral contraceptive combinations is made.

The frequency of both subarachnoid hemorrhage and thrombotic stroke has been reported by some investigators to be higher in women taking oral contraceptive hormones. However, other investigators have suggested that the risk of these effects for women using newer low dose formulations are very small for young women without underlying cardiovascular disease or other risk factors.[Ref]

Endocrine

Endocrine and metabolic effects include complex alterations in plasma lipid profiles and carbohydrate metabolism. In addition, oral contraceptive use has been reported to cause conception delay.[Ref]

All the progestins which occur in commercially available oral contraceptive combinations have adverse effects on lipid profiles. Specifically, these progestins exert antiestrogen and androgen effects and decrease HDL (and HDL2) cholesterol levels and increase LDL cholesterol levels. However, the estrogens in oral contraceptive combinations exert opposing effects. Consequently, alterations in lipid profiles are related to the relative amount and potency of the specific estrogen and progestin in a given product. (Norgestimate exerts strong progestin and antiestrogen effects.)

A number of investigations have suggested that oral contraceptive combinations may decrease glucose tolerance. However, some recent studies with low dose preparations have suggested that decreases in glucose tolerance due to oral contraceptive combinations are generally minimal.

Despite the potentially adverse effects of oral contraceptives on lipid levels and glucose tolerance, some investigators have suggested that young diabetic women without existing vascular disease or severe lipidemias may be candidates for low dose oral contraceptive combinations provided that they receive close monitoring for adverse metabolic effects.[Ref]

Hepatic

Hepatic side effects include focal nodular hyperplasia, intrahepatic cholestasis, liver cell adenomas, hepatic granulomas, hepatic hemangiomas and well-differentiated hepatocellular carcinomas, which have been reported rarely in association with estrogen therapy and therapy with oral contraceptive combinations.[Ref]

The rate of death due to hepatocellular carcinoma in the United States has not changed during the last 25 years (a time during which use of oral contraceptive hormones has increased dramatically).

A committee of the World Health Organization has reported that in developing countries where hepatitis B virus infection and hepatocellular carcinoma are common, "short term use of oral contraceptives does not appear to be associated with an increased risk. Data on the effects of long term use are scarce."

A recent Italian case-control study of women with hepatocellular carcinoma has suggested that the relative risk of hepatocellular carcinoma is 2.2 for oral contraceptive users compared to women who never used oral contraceptives.

A similar American case-control study from 1989 also reported a strong association between oral contraceptive use and hepatocellular carcinoma but concluded that: "If this observed association is causal, the actual number of cases of liver cancer in the United States attributable to oral contraceptive use is small. Therefore, these findings do not have public health importance in the United States and other Western nations."[Ref]

Hematologic

Cases of venous thrombosis, pulmonary embolism (sometimes fatal), and arterial thrombosis have been reported rarely.

Previous thrombotic disease is considered a contraindication to use of oral contraceptive combinations.[Ref]

A hematologic concern is the risk of thromboembolism that is associated with the use of exogenous estrogens. However, because the dose of exogenous estrogens is low in most commercially available preparations, the risk of thromboembolism is minimal for most women (except women who are over age 35 and smoke and women with a history of previous thrombotic diseases).[Ref]

Genitourinary

A common genitourinary side effect is breakthrough bleeding and spotting, especially during the first several cycles of oral contraceptive use. Non-hormonal causes of such bleeding should be excluded.[Ref]

Some women experience oligomenorrhea and amenorrhea following termination or oral contraceptive use.[Ref]

Psychiatric

Psychiatric side effects include depression and precipitation of panic disorder.[Ref]

Immunologic

Immunologic side effects include cases of oral contraceptive-induced systemic lupus erythematosus which have been reported rarely.[Ref]

Other

A case of fatal pulmonary venooclusive disease has been associated with oral contraceptive therapy.[Ref]
