Proactive Retreatment Scheduling

What to Expect

After Your Appointment

Ongoing Retreatment

Twice yearly BOTOX® treatment* frees you from daily overactive bladder (OAB) pills when they aren't working well enough or can't be tolerated

So you can tell your doctor, “See you in 6 months”

Although OAB is a chronic condition that requires ongoing care, just 1 BOTOX® treatment can last up to 6 months*

Understanding Potential Side Effects


BOTOX® Safety and Side Effects

Understand the risks as well as benefits

It's always important to consider the potential side effects of any medication and equally weigh the benefits and risks with your doctor before making a decision.

The most common side effects (≥ 5% and > placebo) in clinical trials for OAB were:

  • urinary tract infection
  • painful or difficult urination
  • temporary inability to fully empty your bladder

Nearly all patients could still urinate when they needed to after BOTOX® treatment; however, there have been instances where some people temporarily could not fully empty their bladder on their own. If you have difficulty fully emptying your bladder after receiving BOTOX®, you may need to use disposable self-catheters. A self-catheter is not like the kind you see in a hospital. It is much smaller (fits in your purse or pocket), easy to use, and you use it by yourself.

You should not receive BOTOX® if you currently have a urinary tract infection (UTI) or are not willing (or able) to use a disposable self-catheter if necessary.

This list is not a complete list of possible serious side effects. Please see Important Safety Information Including Boxed Warning. Talk to an OAB Specialist familiar with BOTOX® if you have any concerns.

1 in 100 people who started BOTOX®, treatment stopped due to side effects in clinical trials.*

*Discontinuation rate in BOTOX® pivotal trials due to adverse events: 1.4% for BOTOX® (n = 552) vs 1.7% for placebo (n = 542).
