Detrusin Tolterodine Tartrate Clarithromycin
ModerateClarithromycin strongly slows the liver enzyme that breaks down tolterodine (Uritol), so more tolterodine stays in your blood. To lower the chance of side effects, the recommended Uritol dose is 2 mg a day.
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.
What to do: Ask your doctor or pharmacist to confirm your Uritol dose. Do not change it yourself.
