Charlotte 24 Fe Oral: Uses, Side Effects, Interactions

This combined hormone medication is utilized to prevent pregnancy. It comprises two hormones: norethindrone (a progestin) and ethinyl estradiol (an estrogen). In the fourth week, there are four inactive pills, each containing a small amount of iron (ferrous fumarate). These inactive pills do not contain any hormones and are included to help maintain the daily pill-taking routine. However, they do not contain enough iron to address iron deficiency. In addition to its contraceptive effects, birth control pills can regulate periods, reduce menstrual blood loss and pain, lower the risk of ovarian cysts, and treat acne. It's important to note that using this medication does not provide protection against sexually transmitted diseases such as HIV, gonorrhea, and chlamydia.
