Pharmacist Analysis
There is evidence to suggest that saw palmetto, a commonly used herbal supplement, may reduce the effectiveness of contraceptive drugs due to the herb's potential antiestrogenic effects, which may interfere with the hormonal balance needed for effective contraception.
Contraceptive drugs work by regulating hormones in the body, preventing ovulation, and creating an unfavorable environment for fertilization. However, when saw palmetto is taken concomitantly, it may interfere with these hormonal processes, reducing the effectiveness of the contraceptive drugs.
While there is still much research to be done on the potential interactions between saw palmetto and contraceptive drugs, it is important to speak with a healthcare provider before taking any new supplements or making changes to current medications.

Saw Palmetto Overview
Norgestrel Overview
-
Progestin-only (norethindrone) oral contraceptives are used to prevent pregnancy. Progestin is a female hormone. It works by preventing the release of eggs from the ovaries (ovulation) and changing the cervical mucus and the lining of the uterus. Progestin-only (norethindrone) oral contraceptives are a very effective method of birth control, but they do not prevent the spread of AIDS and other sexually transmitted diseases.
