Giane Cyproterone Acetate + Ethinyl Estradiol Rifampicin
ModerateTaking rifampicin along with cyproterone acetate and ethinyl estradiol can make this tablet work less well. Rifampicin speeds up how the liver breaks down estrogen, so less of it stays in the body to do its job.
These medicines are often taken together with some care. Your doctor may change a dose, space them apart or check on you more often. Make sure your doctor and pharmacist know you take both.
