Cigarette smoking increases the risk of serious heart and blood vessel side effects from birth control pill use. This risk increases with age and with heavy smoking (15 or more cigarettes per day) and is quite significant in women older than 35 years of age. Women who use birth control pills are strongly advised not to smoke.
Microgestin Fe is used for:
Prevention of pregnancy. It may also be used to regulate the menstrual cycle. It does NOT protect against HIV infection (AIDS) and other sexually transmitted diseases (STDs). It may be used to treat certain conditions as determined by your doctor.
Microgestin Fe is a combination of 2 female sex hormones, estrogen and progestin. Microgestin Fe works by preventing the ovaries from releasing eggs. When there is no egg to be fertilized, pregnancy cannot occur. It also thickens the cervical mucus, making it difficult for sperm to enter the uterus.
Do NOT use Microgestin Fe if:
- you are allergic to any ingredient in Microgestin Fe
- you are pregnant or think you may be pregnant
- you have or have ever had abnormal growth or cancer of the breast, cervical or uterine cancer, or unexplained vaginal bleeding
- you have or have ever had stoppage or rupture of blood vessels in the brain (stroke); blockage of blood vessels (blood clots) in the legs, lungs, heart (heart attack or angina/chest pain), or other parts of the body; heart valve problems; or severe high blood pressure
- you have liver disease, liver tumors, or yellowing of the eyes or skin during pregnancy or during previous use of Microgestin Fe or a similar medicine
- you are currently taking acitretin, aprepitant, barbiturates (eg, phenobarbital), bosentan, carbamazepine, felbamate, griseofulvin, hydantoins (eg, phenytoin), modafinil, nevirapine, penicillins (eg, amoxicillin), protease inhibitors (eg, indinavir), rifamycins (eg, rifampin), St. John's wort, tetracyclines (eg, doxycycline), topiramate, or troglitazone
Contact your doctor or health care provider right away if any of these apply to you.

- An extra patient leaflet is available with Microgestin Fe. Talk to your pharmacist if you have questions about this information.
- Take Microgestin Fe by mouth with food.
- If you have trouble remembering to take Microgestin Fe, talk to your doctor about how to make pill-taking easier or about using another method of birth control.
