Used for:

  • Overactive bladder
  • Interstitial Cystitis / Painful bladder syndrome

The aim:

The aim of Botox is to reduce the sensation of suddenly and urgently needing to pass urine. In patients with Interstitial Cystitis/ painful bladder syndrome, the aim is to alleviate some the pain and also to minimise the urgency.

The procedure:

This can be done under sedation or under local anaesthetic. A cystoscope is placed into the bladder via the urethra (where the urine comes out) and the muscle of the bladder is injected multiple times with the botox.


  • The symptoms will return in 6 to 12 months (usually 9) as the botox wears off – close to 100%
  • You may have blood in the urine and pain and stinging when passing urine – close to 100%
  • The Botox will not help symptoms in about 10% of people
  • There is a risk of getting a urine infection – about 15%
  • There is a risk of having difficulty passing urine for a short time after the botox. About 4%
  • Severe reactions occur in 0.05% of people which includes allergy to botox and generalised weakness.
