Overactive bladder (OAB) causes frequent urges to urinate, which may result in leaks or constant trips to the bathroom. This can make daily life feel unpredictable and, at times, quite frustrating. While there are several treatment options and urology supplies available to help manage symptoms, one procedure offers effective, long-lasting relief: Botox injections. Here, we'll review some important information about Botox injection for OAB and whether it's the right choice for you.
In this article, you’ll learn:
- What overactive bladder (OAB) is, including its common causes, symptoms, and how it affects daily life.
- How Botox injections work for OAB by relaxing bladder muscles, increasing capacity, and improving control to reduce leaks and urgency.
- Who’s a good candidate for Botox treatment, typically those who haven’t responded to medications or lifestyle changes.
- What to expect before, during, and after the procedure, including preparation steps, the injection process, and a short recovery time.
- How effective Botox is for OAB, with most patients seeing results in 1–2 weeks that last 6–9 months.
- How Botox compares to other OAB treatments, offering a long-lasting, minimally invasive option for moderate to severe symptoms.
- When to talk to your doctor if you experience ongoing urinary urgency, frequency, or leakage and want to explore whether Botox is right for you.
What Is Overactive Bladder (OAB)?
Overactive bladder is a fairly common condition that causes sudden, frequent urges to urinate. It happens when the bladder muscles contract involuntarily, even when the bladder isn’t full. Although several things can increase your risk for OAB, some of the most common include neurological disorders like multiple sclerosis or a stroke, spinal cord injury, diabetes, urinary tract infections, enlarged prostate, weakening pelvic floor muscles, and more. Working with your doctor will help you better understand the underlying cause and, therefore, the correct treatment option. If you experience any of the following symptoms of overactive bladder, it's important to see your doctor for diagnostic testing:
- Urgency incontinence
- Urinating more than eight times in 24 hours
- Waking up multiple times at night to urinate (nocturia)
- Accidental urine leakage following a sudden urge (urge incontinence)
Luckily, several effective treatments can make a significant difference in continence and quality of life. One increasingly popular option involves Botox injections into the bladder.
How Botox Works for Overactive Bladder
Botox is the brand name for onabotulinumtoxinA (or botulinum toxin), a purified form of a protein made by the Clostridium botulinum bacterium. While it’s best known for smoothing facial wrinkles, Botox is also widely used in medicine to treat various muscle and nerve-related conditions, including chronic migraines, muscle spasms, and an overactive bladder.
It works by blocking nerve signals that tell muscles to contract. When injected in small, controlled doses, Botox temporarily relaxes the targeted muscle, reducing unwanted movements or spasms. Therefore, Botox works as an effective treatment for OAB by targeting the root cause of the symptoms, overactive muscle contractions in the bladder. It can help individuals with:
- Bladder muscle relaxation: In people with OAB, the bladder’s detrusor muscle contracts too often, even when the bladder isn’t full. Botox blocks the nerve signals that trigger these unwanted contractions, allowing the muscle to relax.
- Increased bladder capacity: As the bladder relaxes, it can hold more urine comfortably. This reduces the feeling of urgency and the frequency of bathroom trips.
- Improved bladder control: With fewer involuntary contractions, there are fewer episodes of urge incontinence and better bladder control.
- Targeted and temporary effect: Botox is injected directly into the bladder wall through a minimally invasive cystoscopy procedure. Its effects are localized, so it won't affect muscles elsewhere in the body. Results typically last about six months (longer in some individuals), after which you can receive additional injections.
Botox has been FDA-approved as a treatment for overactive bladder for both men and women since January 2013. Still, it's always important to talk to your doctor about whether it's the right option for your specific circumstances.
Who's a Good Candidate for Botox Treatment?
Most individuals handle Botox injections in the bladder well, and it's typically used as a treatment for individuals who haven't experienced any relief from other options (i.e., medications or lifestyle modifications). You may be a good candidate for bladder Botox treatment if you:
- Have persistent overactive bladder symptoms such as frequency or urge incontinence.
- Have tried lifestyle changes (like fluid management, bladder training, or pelvic floor exercises) without success.
- Have not responded well to oral medications (such as anticholinergics or beta-3 agonists), or experienced unwanted side effects from them.
- Are willing to undergo a minor in-office procedure using a cystoscope (a thin tube with a camera) to inject Botox in the bladder wall.
- Do not have an active UTI at the time of treatment.
- Are able to perform self-catheterization, if necessary, since a small number of people may temporarily have difficulty fully emptying their bladder after the injection.
Individuals who are experiencing stress incontinence typically do not see effective results from Botox, as the leaks aren't related to bladder spasms.
What Happens During a Bladder Botox Injection and How to Prepare
If your doctor has identified you as a good candidate for the use of Botox, it’s important to prepare properly to ensure a smooth and successful treatment. Before the procedure, your healthcare provider will review your medical history, current medications, and any previous treatments for OAB. You may also need to complete a urinalysis or urine culture to check for signs of infection. Any additional preparations will be given to you by your doctor when scheduling the procedure.
Most bladder Botox injections are done in a urologist’s office or outpatient clinic and are relatively quick (usually less than 30 minutes). You'll be able to go home the same day and won't need someone to pick you up, as you won't be under general anesthesia. Instead, a local anesthetic or numbing solution is placed in your bladder to keep you comfortable during the injection. The injection is done using a cystoscope that's inserted through the urethra and helps with precision for the injection sites, which can be up to 10 to 20 different places along the bladder wall. Once done, the scope is removed, and you can resume normal activities after leaving the office.
After the Procedure: Recovery and Follow-Up
Since only a local anesthesia is used and the injections typically don't cause lasting pain, recovery is relatively easy. Some people may experience a mild burning during urination, small traces of blood in the urine, or increased frequency for a day or two, but these are normal and should subside quickly. In very rare cases, allergic reactions may occur. Your doctor will discuss these risks with you before the procedure.
You'll also need to see your doctor or urologist for a follow-up treatment within one to two weeks. This will allow your doctor to test for any signs of urinary retention using an ultrasound or post-void residual test. If this occurs, your doctor will help you determine further steps to address retention.
Results and Effectiveness
Most patients begin to notice improvement within one to two weeks after the injection. The results may last between six and nine months, depending on your body’s response and how quickly the Botox wears off. Clinical studies show that Botox can:
- Reduce the number of daily bathroom trips
- Decrease urgency and leakage episodes
- Improve sleep quality and overall comfort
When symptoms gradually return, the treatment can be repeated. Many patients continue Botox therapy long-term with consistent results and high satisfaction rates.
Comparing Botox With Other Overactive Bladder Treatments
Botox is an excellent option for adults with moderate to severe OAB symptoms who haven’t found success with other therapies and want a long-lasting, minimally invasive solution. Still, it usually isn’t the first treatment option. Your doctor will likely try a variety of alternative treatments before recommending Botox, such as:
- Bladder training
- Pelvic floor exercises (such as Kegels)
- Scheduled voiding
- Fluid and diet management
- Weight management
- Anticholinergics
- Beta-3 agonists
- Nerve stimulation
In more serious cases, your urologist may recommend bladder augmentation surgery. However, this is typically only considered after Botox injections.
When to Talk to Your Doctor About Botox for Overactive Bladder
If you experience any overactive bladder symptoms, it's important to see your doctor. Although many people feel embarrassed to talk about the loss of bladder control, there are treatment options available. The sooner you schedule an appointment, the sooner you can work towards finding the right options to treat urinary incontinence and overactive bladder, regardless of your age or what's causing it.
Living with OAB can be frustrating and isolating, but effective treatment options like Botox injections can help you take back control of your daily life. Whether you’re just beginning to explore treatment options or ready to take the next step, it’s best to work closely with your healthcare provider to find the approach that fits your needs and lifestyle.
