Drug Interaction Report

Using trospium together with carvedilol may alter the effects of both medications. Contact your doctor if you experience drowsiness, dizziness, lightheadedness, confusion, blurred vision, dry mouth, or difficulty urinating. You may need a dose adjustment or need your blood pressure checked more often to safely use both medications. You should avoid activities requiring mental alertness until you know how the medications will affect you. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

Trospium should be taken on an empty stomach 1 hour before or 2 hours after a meal unless otherwise directed by your doctor. You may experience reduced absorption of trospium in the presence of food. This will make it easier for your body to absorb the medication.
