Patient information: uses, side effects, how to take - TriNessa Kit NDA019653
What is the most important information I should know about MonoNessa or TriNessa?
Do not use MonoNessa or TriNessa 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 MonoNessa or TriNessa?
MonoNessa or TriNessa is a birth control pill (oral contraceptive) used by women to prevent pregnancy.
TriNessa 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"). TriNessa should only be used to treat acne in women who want to take birth control pills to prevent pregnancy.
How does MonoNessa or TriNessa 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 MonoNessa or TriNessa.
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.

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 MonoNessa or TriNessa?
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 MonoNessa or TriNessa, 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 MonoNessa or TriNessa
- Take 1 pill every day at the same time. Take the pills in the order directed on your pill dispenser.
- Do not skip your pills, even if you do not have sex often. If you miss pills (including starting the pack late) you could get pregnant. The more pills you miss, the more likely you are to get pregnant.
- If you have trouble remembering to take MonoNessa or TriNessa, talk to your healthcare provider. When you first start taking MonoNessa or TriNessa, spotting or light bleeding in between your periods may occur. Contact your healthcare provider if this does not go away after a few months.
- You may feel sick to your stomach (nauseous), especially during the first few months of taking MonoNessa or TriNessa. If you feel sick to your stomach, do not stop taking the pill. The problem will usually go away. If your nausea does not go away, call your healthcare provider.
- Missing pills can also cause spotting or light bleeding, even when you take the missed pills later. On the days you take 2 pills to make up for missed pills (see What should I do if I miss any MonoNessa or TriNessa pills? below), you could also feel a little sick to your stomach.
- It is not uncommon to miss a period. However, if you miss a period and have not taken MonoNessa or TriNessa according to directions, or miss 2 periods in a row, or feel like you may be pregnant, call your healthcare provider. If you have a positive pregnancy test, you should stop taking MonoNessa or TriNessa.
- If you have vomiting or diarrhea within 3–4 hours of taking your pill, take another pill of the same color from your extra pill dispenser. If you do not have an extra pill dispenser, take the next pill in your pill dispenser. Continue taking all your remaining pills in order. 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.
- If you have vomiting or diarrhea for more than 1 day, your birth control pills may not work as well. Use an additional birth control method, like condoms and a spermicide, until you check with your healthcare provider.
- Stop taking MonoNessa or TriNessa at least 4 weeks before you have major surgery and do not restart after the surgery without asking your healthcare provider. Be sure to use other forms of contraception (like condoms and spermicide) during this time period.
Before you start taking MonoNessa or TriNessa:
- Decide what time of day you want to take your pill. It is important to take it at the same time every day and in the order as directed on your pill dispenser.
- Have backup contraception (condoms and spermicide) available and if possible, an extra full pack of pills as needed.
When should I start taking MonoNessa or TriNessa?
If you start taking MonoNessa or TriNessa and you have not used a hormonal birth control method before:
- There are 2 ways to start taking your birth control pills. You can either start on a Sunday (Sunday Start) or on the first day (Day 1) of your natural menstrual period (Day 1 Start). Your healthcare provider should tell you when to start taking your birth control pill.
- If you use the Sunday Start, use non-hormonal back-up contraception such as condoms and spermicide for the first 7 days that you take MonoNessa or TriNessa. You do not need back-up contraception if you use the Day 1 Start.
If you start taking MonoNessa or TriNessa and you are switching from another birth control pill:
- Start your new MonoNessa or TriNessa pack on the same day that you would start the next pack of your previous birth control method.
- Do not continue taking the pills from your previous birth control pack.
If you start taking MonoNessa or TriNessa and previously used a vaginal ring or transdermal patch:
- Start using MonoNessa or TriNessa on the day you would have reapplied the next ring or patch.
If you start taking MonoNessa or TriNessa and you are switching from a progestin-only method such as an implant or injection:
- Start taking MonoNessa or TriNessa on the day of removal of your implant or on the day when you would have had your next injection.
If you start taking MonoNessa or TriNessa and you are switching from an intrauterine device or system (IUD or IUS):
- Start taking MonoNessa or TriNessa on the day of removal of your IUD or IUS.
- You do not need back-up contraception if your IUD or IUS is removed on the first day (Day 1) of your period. If your IUD or IUS is removed on any other day, use non-hormonal back-up contraception such as condoms and spermicide for the first 7 days that you take MonoNessa or TriNessa.
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 MonoNessa or TriNessa? " above. Follow these instructions for either a Sunday Start or a Day 1 Start.
