Tri-Previfem is an oral contraceptive that also works for treating acne. It is a triphasic birth control pill, meaning there are three different "phases" of pills in each pack, each with a different amount of the progesterone hormone. Tri-Previfem prevents pregnancy by stopping ovulation and altering cervical mucus and the lining of the uterus. Potential side effects include breakthrough bleeding, breast tenderness, and headache.
