Side Effects

Drug information provided by: Micromedex

Healthy women who do not smoke cigarettes have almost no chance of having a severe side effect from taking oral contraceptives. For most women, more problems occur because of pregnancy than will occur from taking oral contraceptives. But for some women who have special health problems, oral contraceptives can cause some unwanted effects. Some of these unwanted effects include benign (not cancerous) liver tumors, liver cancer, or blood clots or related problems, such as a stroke. Although these effects are very rare, they can be serious enough to cause death. You may want to discuss these effects with your doctor.

Smoking cigarettes during the use of oral contraceptives has been found to greatly increase the chances of these serious side effects occurring. To reduce the risk of serious side effects, do not smoke cigarettes while you are taking oral contraceptives. Cigarette smoking increases the risk of serious cardiovascular side effects from oral contraceptive use. The 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.

Along with its needed effects, a medicine may cause some unwanted effects. Although not all of these side effects may occur, if they do occur they may need medical attention.

The following side effects may be caused by blood clots. Get emergency help immediately if any of the following side effects occur:
