Botox (onabotulinumtoxinA) for
Overactive Bladder (OAB)

Botox (onabotulinumtoxinA) is an FDA-approved treatment for overactive bladder (OAB), especially when other treatments, like medications or behavioral therapies, haven’t provided sufficient relief.

How the Procedure Works

Botox works by temporarily relaxing the bladder muscle (detrusor), reducing involuntary contractions that cause urgency and leakage. It allows the bladder to hold more urine and reduces the number of times you feel the urge to go.

Completed in an outpatient setting, using a cystoscope, Botox is injected into several sites in the bladder wall using a tiny needle. Local anesthetic or light sedation is typically used. The procedure takes 10-20 minutes.

Advantages of Botox

  • Significant reduction in urgency and incontinence episodes

  • Improved quality of life

  • Effective even for patients who found oral medications ineffective

Recovery

  • Results begin within 5-7 days, with effect in about 2 weeks

  • Improvement lasts 6 months on average

  • Repeat treatments are scheduled as needed
