Frequently Asked Questions (FAQ)

Can I drink alcohol with trospium?

Trospium normally makes you feel tired, and alcohol could worsen this. Take extra care to avoid drinking alcohol within 2 hours of taking the extended-release version, so that you do not feel extremely drowsy.

Should I take trospium with or without food?

Food can make this medication less effective, so you need to take trospium with water at least 1 hour before meals or on an empty stomach.

Can I just stop taking trospium?

If you stop taking trospium, your overactive bladder could get worse. Talk to your provider about other treatment options before you stop the medication.
