Femcon Fe Side Effects Center
Medical Editor: John P. Cunha, DO, FACOEP
Femcon Fe (norethindrone and ethinyl estradiol) is a combination of female hormones used as contraception to prevent pregnancy. Femcon Fe is also used to treat severe acne. Femcon Fe is available in generic form. Common side effects of Femcon Fe include nausea (especially when you first start taking Femcon Fe), vomiting, headache, stomach cramping or bloating, dizziness, vaginal discomfort/irritation/itching, increased vaginal fluids or discharge, breast tenderness/enlargement, nipple discharge, freckles or darkening of facial skin, increased hair growth, loss of scalp hair, changes in weight or appetite, problems with contact lenses, or decreased sex drive. Acne may improve or get worse. Vaginal bleeding between periods (spotting) or missed/irregular menstrual periods may occur, especially during the first few months of use.
The dosage of Femcon Fe is one white tablet daily for 21 consecutive days, followed by one brown tablet daily for 7 consecutive days, taken at the same time each day. Take as prescribed. Femcon Fe may interact with acetaminophen, ascorbic acid, prednisolone, theophylline, St. John's wort, antibiotics, seizure medications, barbiturate sedatives, or HIV or AIDS medications. Tell your doctor all medications and supplements you use. Femcon Fe must not be used during pregnancy. If you become pregnant or think you may be pregnant, tell your doctor. If you have just given birth or had a pregnancy loss/abortion after the first 3 months, consult your doctor about birth control, and find out when it is safe to use birth control containing estrogen, such as this medication. This medication passes into breast milk. This may affect milk production and may have undesirable effects on a nursing infant. Consult your doctor before breastfeeding.
