What happens if I miss a dose?
Missing a pill increases your risk of becoming pregnant.
If you miss one "active" pill, take two pills on the day that you remember. Then take one pill per day for the rest of the pack.
If you miss two "active" pills in a row in week one or two, take two pills per day for two days in a row. Then take one pill per day for the rest of the pack. Use back-up birth control for at least 7 days.
If you miss two "active" pills in a row in week three, or if you miss three pills in a row during any of the first 3 weeks, throw out the rest of the pack and start a new one the same day if you are a Day 1 starter. If you are a Sunday starter, keep taking a pill every day until Sunday. On Sunday, throw out the rest of the pack and start a new one that day.
If you miss two or more pills, you may not have a period during the month. If you miss a period for two months in a row, call your doctor because you might be pregnant.
If you miss any reminder pills, throw them away and keep taking one pill per day until the pack is empty. You do not need back-up birth control if you miss a reminder pill.
What happens if I overdose?
Seek emergency medical attention or call the Poison Help line at 1-800-222-1222. Overdose symptoms may include severe nausea or vaginal bleeding.
What should I avoid while taking ethinyl estradiol and norgestimate?
Do not smoke while using birth control pills, especially if you are older than 35. Smoking can increase your risk of blood clots, stroke, or heart attack caused by birth control pills.
Birth control pills will not protect you from sexually transmitted diseases--including HIV and AIDS. Using a condom is the only way to protect yourself from these diseases.
What other drugs will affect ethinyl estradiol and norgestimate?
Some drugs can make ethinyl estradiol and norgestimate less effective, which may result in pregnancy. Before using ethinyl estradiol and norgestimate, tell your doctor if you are using any of the following drugs:
- bosentan (Tracleer);
- St. John's wort;
- an antibiotic;
- HIV or AIDS medications;
- phenobarbital (Solfoton) and other barbiturates; or
- seizure medication.
This list is not complete and other drugs may interact with birth control pills. Tell your doctor about all medications you use. This includes prescription, over-the-counter, vitamin, and herbal products. Do not start a new medication without telling your doctor.
Where can I get more information?
Your pharmacist can provide more information about ethinyl estradiol and norgestimate.
Remember, keep this and all other medicines out of the reach of children, never share your medicines with others, and use this medication only for the indication prescribed.
