Venesa Dienogest Clarithromycin
ModerateClarithromycin is a CYP3A4 inhibitor, which means it slows down the CYP3A4 enzyme that the body uses to break down progestogens such as Dienogest. Other medicines in this group include azole antifungals (ketoconazole, itraconazole, fluconazole), cimetidine, verapamil, other macrolides (erythromycin, roxithromycin), diltiazem, protease inhibitors (ritonavir, saquinavir, indinavir, nelfinavir) and some antidepressants (nefazodone, fluvoxamine, fluoxetine). When Dienogest is taken with clarithromycin, the level of the hormone in your blood can go up, and this may cause more side effects.
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.
