How is botulinum toxin A used for overactive bladder?

Dr. Darria Long Gillespie, MD
Emergency Medicine
Botulinum toxin A (Botox) is approved by the FDA for treating overactive bladder when symptoms cannot be controlled by anticholinergic drugs. It is also approved for people who are unable to take these drugs.

The toxin is injected into the bladder wall in an outpatient procedure, under local anesthetic. The treatment increases bladder's capacity and improves symptoms. The effects usually last for several months. Then the treatment must be repeated. People who receive these injections sometimes get urinary tract infections or have trouble emptying the bladder completely.
