Botox Q & A

How can BOTOX® help me?

BOTOX® works on the bladder muscle by blocking the nerve signals that trigger your overactive bladder. BOTOX® is a different treatment option when other types of medications do not work well enough or cannot be taken.

BOTOX® reduces bladder contractions and can:

  1. Reduce weekly urinary leakage episodes
  2. Increase bladder capacity
  3. Decrease pressure in your bladder

How is BOTOX® administered?

It is a prescription medication injected into the bladder muscle.

Is BOTOX® right for me?

Make an appointment and talk to your doctor about the symptoms you may be experiencing.

BOTOX® is used for those who want to:

  • Treat overactive bladder symptoms (strong need to urinate and leakage, wetting, frequency symptoms)
  • When other medications (anticholinergic) medications do not work well enough
  • To treat leakage of urine in adults with overactive bladder due to neurological condition, who still have leakage and cannot tolerate side effects after trying another medication.

What kind of results can I expect and how soon will I see them?

BOTOX® is proven to significantly reduce the number of weekly urinary leakage episodes – usually 6 weeks after treatment.

In trials, patients saw improvements as soon as 2 weeks after treatment, and lasted up to 10 months.

What are some of the common side effects with BOTOX® treatment?

Common side effects within the first 12 weeks:

  • Urinary tract infection (UTI)
  • Urinary retention (not being able to empty the bladder completely)
  • Hematuria (blood in urine)
  • Fatigue
  • Insomnia

What can I expect during my treatment of BOTOX®?

BOTOX® is a prescription medication injected into the bladder muscle by your urologist. Dr. Yamada will perform the procedure by first numbing your bladder and then administering the BOTOX® injection.

Before treatment:

  • Discuss the treatment with your doctor and the results you may expect
  • Instructions to stop taking antiplatelets (i.e. Aspirin like medications) for atleast 3 days before treatment
  • Given antibiotics 3 days before treatment to help prevent UTIs
  • Informed that some patients may have to begin using a catheter after treatment
  • Information on how to catheterize should the need arise


On treatment day:

  • Test to make sure patient does not have a UTI
  • Give antibiotics to prevent UTI
  • Explain options for anesthesia – no anesthesia, local, regional, or general
  • Administration of BOTOX® 
    • Small injections in bladder wall after anesthesia is administered
    • Can be done in office or at the hospital
  • Entire process can take less than an hour


After treatment:

  • Stay in office for about 30 minutes to check blood pressure and pulse rate and to ensure bladder is empty
  • Antibiotics given for 1-3 days after treatment
  • Check whether urine is left in bladder after you urinate
    • Usually 2 weeks after treatment and thereafter as Dr. Yamada considers medically appropriate
