Tolterodine
Tolterodine relaxes involuntary bladder contractions and may reduce urgency, frequency and leakage in overactive bladder. Infection or obstruction can cause similar symptoms. Immediate- and extended-release products have different instructions and should not be substituted without checking the treatment plan.
Key points
- New bladder symptoms should be assessed before antimuscarinic treatment.
- Urinary retention, severe constipation, narrow-angle glaucoma and long-QT risk can make tolterodine unsafe.
- Inability to urinate, severe abdominal swelling or a painful red eye with blurred vision needs urgent care.
Listings are for comparison only. Suitability and supply depend on clinician and pharmacy checks, stock, destination rules and prescription requirements.
Important safety checks
Bladder emptying, bowel function, glaucoma, liver or kidney disease, heart rhythm and other anticholinergic medicines require review. Dry mouth and constipation can occur. Reduced sweating can increase heat-illness risk.
When to seek urgent care
Seek urgent help for inability to urinate with severe lower-abdominal pain, severe abdominal swelling with vomiting or inability to pass stool, a painful red eye with halos or blurred vision, fainting with an irregular heartbeat, severe confusion or heat illness.
