Urigin Tolterodine Tartrate Erythromycin
ModerateErythromycin is a strong CYP3A4 inhibitor, meaning it slows down the CYP3A4 enzyme the body uses to break down Tolterodine. Other medicines that do this include Ketoconazole, Itraconazole, Miconazole, Clarithromycin, Cyclosporine and Vinblastine. If you take Tolterodine (Uritol) together with any of these, the recommended dose of Uritol is 2 mg daily.
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.
