What is the most important information I should know about trospium (Sanctura XR)?

You should not take this medicine if you are allergic to trospium, or if you have untreated or uncontrolled narrow-angle glaucoma, a blockage in your digestive system, or if you are unable to urinate.

Take trospium on an empty stomach, at least 1 hour before a meal.

Avoid drinking alcohol within 2 hours before or after you take trospium. Drinking alcohol can increase certain side effects of trospium.

Avoid becoming overheated or dehydrated during exercise and in hot weather. Trospium can decrease sweating, which makes it easier for you to have heat stroke. Drink plenty of fluids while you are taking this medication.

Before using trospium, tell your doctor if you regularly use other medicines that make you sleepy (such as cold or allergy medicine, sedatives, narcotic pain medicine, sleeping pills, muscle relaxers, and medicine for seizures, depression, or anxiety). They can add to sleepiness caused by trospium.
