Dinosen Dienogest Cimetidine
ModerateCimetidine is a known CYP3A4 inhibitor, meaning it slows down the CYP3A4 enzyme that the body uses to break down Dienogest. Other medicines in this group include azole antifungals (ketoconazole, itraconazole, fluconazole), verapamil, macrolide antibiotics (erythromycin, clarithromycin, roxithromycin), diltiazem, protease inhibitors (ritonavir, saquinavir, indinavir, nelfinavir) and some antidepressants (nefazodone, fluvoxamine, fluoxetine). When Dienogest is taken with Cimetidine, the level of Dienogest, which is a progestogen, in the blood may go up, and this can lead to 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.
