Botulinum toxin is widely known by one of its trade names, Botox. It is a strong toxic substance which is used in cosmetic surgery and for medical purposes.
- For overactive bladder (OAB) symptoms, botulinum toxin is injected into the bladder wall to reduce the nerve activity that causes the symptoms. This treatment may improve the symptoms of urgency, frequency of urinating, and urgency incontinence.
- Botulinum toxin blocks nerve endings and relaxes the smooth muscle in the prostate.
The effect of the toxin will wear off after 4–9 months. As symptoms return, you will need to have another treatment.
