Uses for TriNessa 28
Ethinyl estradiol and norgestimate combination is used to prevent pregnancy. It is a birth control pill that contains two hormones, ethinyl estradiol and norgestimate, and when taken correctly, it can stop pregnancy. It works by preventing a woman's egg from fully developing each month. This means the egg cannot accept sperm, which prevents fertilization (pregnancy).
Ethinyl estradiol and norgestimate combination is also used to treat moderate acne in females (at least 15 years old) who have started their menstrual period and also want to use this medicine for birth control.
No contraceptive method is 100 percent effective. Other birth control methods, such as surgery to become sterile or abstaining from sex, are more effective than birth control pills. Talk to your doctor about your birth control options.
This medicine does not prevent HIV infection or other sexually transmitted diseases. It will not work as emergency contraception after unprotected sexual contact.
This medicine is available only with your doctor's prescription.

Precautions while using TriNessa 28
It is very important for your doctor to check your progress at regular visits to ensure this medicine is working properly and does not cause unwanted effects. These visits will usually be every 6 to 12 months, but some doctors may want to see you more often. Your doctor may also want to check your blood pressure while you are taking this medicine.
Even though you are using this medicine to prevent pregnancy, you should know that using this medicine while you are pregnant could harm your unborn baby. If you think you may be pregnant while using this medicine, tell your doctor right away. Make sure your doctor knows if you had given birth within 4 weeks before starting this medicine.
Do not use this medicine with treatments for hepatitis C virus infection, including ombitasvir/paritaprevir/ritonavir, with or without dasabuvir (Technivie®, Viekira Pak®).
This medicine will not protect you from getting HIV/AIDS, herpes, or other sexually transmitted diseases. Tell your doctor if you or your partner start having sexual intercourse with other people, or if you or your partner tests positive for a sexually transmitted disease. If this worries you, talk with your doctor.
Vaginal bleeding of various amounts may happen between your regular menstrual periods during the first 3 months of use. This is sometimes called spotting when slight, or breakthrough bleeding when heavier.
- If this happens, continue with your regular dosing schedule.
- The bleeding usually stops within 1 week. Check with your doctor if the bleeding lasts more than 1 week.
- If the bleeding continues after you have been taking hormonal contraceptives as directed for more than 3 months, check with your doctor.
Check with your doctor right away if you miss a menstrual period. Missed periods may happen if you skip one or more tablets and have not taken your pills exactly as directed. If you miss two periods in a row, talk to your doctor. You might need a pregnancy test.
If you think you may be pregnant, stop taking this medicine immediately and check with your doctor.
Do not use this medicine if you smoke cigarettes or if you are over 35 years old. If you smoke while using birth control pills, you increase your risk of blood clots, heart attacks, or strokes. Your risk is even higher if you are over 35, have diabetes, high blood pressure, high cholesterol, or are overweight. Talk with your doctor about ways to stop smoking. Keep your diabetes under control. Ask your doctor about diet and exercise to manage your weight and blood cholesterol levels.
Using this medicine may increase your risk of blood clotting problems. Check with your doctor right away if you experience pain in the chest, groin, or legs, especially the calves, difficulty breathing, a sudden severe headache, slurred speech, sudden unexplained shortness of breath, sudden loss of coordination, or changes in vision while using this medicine.
Using this medicine may increase your risk of breast cancer or cervical cancer. Discuss this risk with your doctor. Check with your doctor immediately if you experience abnormal vaginal bleeding.
Check with your doctor immediately if you wear contact lenses or if you experience blurred vision, difficulty reading, or any other changes in vision during or after treatment. Your doctor may want an eye doctor (ophthalmologist) to examine your eyes.
Check with your doctor right away if you have pain or tenderness in the upper stomach, dark urine or pale stools, or yellowing of the eyes or skin. These could be signs of a serious liver problem.
Using this medicine may increase your risk for gallbladder surgery. Discuss this risk with your doctor.
This medicine may make your skin more sensitive to sunlight. Wear sunscreen. Do not use sunlamps or tanning beds. Inform your doctor if you have a history of dark patches of skin around the forehead, nose, cheeks, and around the mouth, especially during pregnancy.
Check with your doctor before refilling an old prescription, especially after a pregnancy. You will need another physical examination, and your doctor may change your prescription.
Make sure any doctor or dentist who treats you knows that you are using this medicine. This medicine may affect the results of some medical tests. You may also need to stop using this medicine at least 4 weeks before and 2 weeks after having major surgery.
Do not take other medicines unless you have discussed them with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal (e.g., St. John's wort) or vitamin supplements.

Proper use of TriNessa 28
It is very important that you use this medicine exactly as directed by your doctor. Do not use more of it, do not use it more often, and do not use it for a longer time than your doctor ordered.
To make using oral contraceptives as safe and reliable as possible, you should understand how and when to take them and what effects may be expected.
This medicine comes with patient instructions. Read and follow these instructions carefully. Ask your doctor or pharmacist if you have any questions.
This medicine is available in blister packs with a Dialpak® tablet dispenser or a Veridate® tablet dispenser. Each blister pack contains 28 tablets with different colors that need to be taken in the same order as directed on the blister pack.
When you begin using this medicine, your body will require at least 7 days to adjust before a pregnancy will be prevented. Use a second form of contraception (eg, condom, spermicide, or diaphragm) for the first 7 days of your first cycle of pills.
Take this medicine at the same time each day with or without food. Birth control pills work best when no more than 24 hours pass between doses.
Do not skip or delay taking your pill by more than 24 hours. If you miss a dose, you could get pregnant. Ask your doctor for ways to help you remember to take your pills or about using another method of birth control.
You may feel sick or nauseated, especially during the first few months that you take this medicine. If your nausea is continuous and does not go away, call your doctor.

Your doctor may ask you to begin your dose on the first day of your menstrual period (called Day 1 start) or on the first Sunday after your menstrual period starts (called Sunday start). When you begin on a certain day it is important that you follow that schedule, even if you miss a dose. Do not change your schedule on your own. If the schedule that you use is not convenient, talk with your doctor about changing it. For a Sunday start, you need to use another form of birth control (eg, condom, diaphragm, spermicide) for the first 7 days.
You should begin your next and all subsequent 28-day regimens of therapy on the same day of the week as the first regimen began and follow the same schedule.
