Loestrin 24 Fe

Loestrin Fe Side Effects Center

Medical Editor: John P. Cunha, DO, FACOEP

Loestrin 24 Fe (norethindrone acetate and ethinyl estradiol and ferrous sulfate) is used as contraception to prevent pregnancy. It is also used to treat severe acne. It contains a combination of female hormones that prevent ovulation. It also contains iron. This medication may be available in generic form. Common side effects include nausea, vomiting, headache, stomach cramping/bloating, dizziness, vaginal discomfort/irritation, increased vaginal fluids, or breast tenderness/enlargement. Acne may improve or get worse. Vaginal bleeding between periods (spotting) or missed/irregular periods may occur, especially during the first few months of use.

The dose of Loestrin 24 Fe is one white hormone tablet taken daily for 24 consecutive days followed by one brown iron tablet daily for 4 consecutive days. Withdrawal bleeding usually occurs within three days following discontinuation of white tablets and may not have finished before the next pack is started. Follow package or physician instructions. Loestrin 24 Fe may interact with acetaminophen, ascorbic acid (vitamin C), prednisolone, theophylline, St. John's wort, antibiotics, seizure medications, barbiturates, or HIV or AIDS medications. Tell your doctor all medications and supplements you use. Loestrin 24 Fe must not be used during pregnancy. 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 breast-feeding.
