Feanolla is a type of contraceptive pill, specifically classified as a progestogen-only pill (POP), also known as a mini pill. Unlike combined oral contraceptives that contain both estrogen and progestogen, Feanolla relies solely on progestogen. Its active ingredient is desogestrel, which works primarily by preventing the release of an egg from the ovary (ovulation). Additionally, it thickens the mucus in the cervix, making it more difficult for sperm to enter the womb, and alters the lining of the womb to prevent a fertilized egg from implanting. Feanolla is often prescribed to women who are sensitive to estrogen or who are breastfeeding, as it offers a hormone-based contraceptive option without containing estrogen. It's important for users to take the pill at the same time every day for it to be most effective.
