Botox For Overactive Bladder (OAB)

What is Botox for Overactive Bladder?

Botox, otherwise known as Botulinum toxin, is a neuro-toxic protein. When injected into the muscular wall of the bladder, this toxin interrupts the messages sent to the nerves, thus relaxing the bladder. This in turn will help you to hold more in your bladder – giving you more control and minimising leakage.

For those who experience urinary urgency, frequency and incontinence due to an overactive bladder, and when exercises and oral medications have not improved your symptoms – Botox treatment may be helpful.

How is Botox given?

Botox is generally well tolerated. A cystoscope is passed into the bladder through the urine pipe (urethra) and is used to inject the solution of Botulinum toxin. Tiny amounts of diluted Botulinum toxin solution are injected directly in 20 to 30 locations within the bladder muscle using a fine needle. The treatment takes about 20-30 mins and is a day case procedure.

What to expect afterwards

Botox does not work immediately. Patients usually see the positive effects within 2 weeks after treatment. During the first few days after the procedure, you may notice some localised soreness in your bladder, and/or a small amount of blood in your urine.


Botox treatment can provide good results for 6 to 9 months in approximately 2/3 of patients. The effects of Botox will wear off after time – hence this is usually a repeatable treatment. In about 7 in 100 people, Botox may be too effective – causing more paralysis to the bladder than was intended – reducing your ability to go to the toilet. In these rare cases you will need to pass a small catheter into your bladder and empty the urine this way (a process known as intermittent self -catheterisation ISC). This is only temporary, and will not last as long as the effect of the treatment.
