It is very important that your doctor check you closely to make sure this medicine is working properly and does not cause unwanted effects.
Although you are using this medicine to prevent pregnancy, you should know that using this medicine while you are pregnant could harm the unborn baby. Your doctor may give you a pregnancy test before you start using this medicine to make sure you are not pregnant. If you think you have become pregnant while using the medicine, tell your doctor right away.
Call your doctor right away if you have severe lower abdominal or stomach pain 3 to 5 weeks after taking this medicine. You may have a pregnancy outside of the uterus (womb), which is called an ectopic pregnancy. An ectopic pregnancy can be a serious and life-threatening condition. It can also cause problems that may make it harder for you to become pregnant in the future.
You may have some blood spotting a few days after taking this medicine. If the bleeding continues for more than 1 week, check with your doctor right away.
This medicine may make your next monthly period later than expected by a few days. If your next period after taking this medicine is more than 1 week late, check with your doctor right away for a pregnancy test.
This medicine will not protect you from getting HIV/AIDS or other sexually transmitted infections. If this is a concern for you, talk with your doctor.
Your regular birth control method such as birth control pills or patch may not work as well while you are using this medicine. After using this medicine, you must use two forms of birth control. Use birth control pills or patch together with another form of birth control, such as a condom, diaphragm, or contraceptive foam or jelly, during any other times that you have sex in the same monthly period you used this medicine.
Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal (eg, St. John's wort) or vitamin supplements.
