Some medicines can interfere with how
birth control pills work. For example, you may not be
protected from pregnancy while you are taking other medicines that affect liver
metabolism. The vaginal ring and skin patch contain combination hormones and
may also interact with some medicines. The progestin-only pills, implant
(such as Implanon and Nexplanon), and shot (Depo-Provera) also contain hormones that may interact
with some medicines.
Taking medicines while you are using
hormonal birth control may increase your risk of problems. Some combinations of
medicine may affect the birth control hormones in your body, making them too
strong or too weak. This may increase your chance of getting pregnant. Or a new
medicine may be less likely to work because you have birth control hormones in
your body. Talk with your doctor or pharmacist to make sure that any medicines
you take are not causing problems when you are using hormonal birth
