The impact of medications on urinary incontinence is often overlooked, but certain prescription and over-the-counter medications can contribute to bladder leaks or make existing symptoms worse. Understanding which medications may be linked to urinary incontinence can help you have informed conversations with your doctor and find the right combination of treatment, lifestyle changes, and incontinence supplies to better manage your symptoms. Here, we'll go over a few specific medications and their impact on UI.
Quick Overview: The Impact of Medications on Urinary Incontinence
- Certain prescription and over-the-counter medications can contribute to urinary incontinence by increasing urine production, relaxing bladder muscles, or affecting nerve signals involved in bladder control.
- Diuretics, blood pressure medications, antidepressants, muscle relaxants, opioids, antihistamines, and sleep aids are among the most common medications associated with bladder control problems.
- Never stop taking a prescribed medication on your own. If you notice new or worsening urinary symptoms, speak with your healthcare provider about possible alternatives or dosage adjustments.
- Managing medication-related incontinence may involve pelvic floor exercises, bladder training, lifestyle changes, prescription treatments, or other medical therapies, depending on the underlying cause.
- Using high-quality incontinence supplies can help reduce leaks, improve comfort, and provide greater confidence while you and your healthcare provider develop the most effective treatment plan.
Can Medications Cause Urinary Incontinence?
Simply put, yes, medications can cause urinary incontinence or make existing problems worse. While incontinence is often associated with aging, pregnancy, childbirth, or certain medical conditions, some prescription and over-the-counter medications can also affect how the bladder stores and releases urine. In some cases, urinary symptoms may begin shortly after starting a new medication or increasing the dosage.
Not everyone experiences medication-related incontinence, and many people take these medications without any problems. However, certain medications can interfere with normal urinary function by:
- Increasing urine production
- Relaxing the muscles that control urination
- Interfering with nerve signals
- Reducing bladder emptying
- Increasing drowsiness or dizziness
Although medication-related UI can affect anyone, some people are more likely to experience it than others. Risk factors include:
- Older adults, who are often more sensitive to medication side effects
- People taking multiple prescription medications
- Individuals with an overactive bladder or existing urinary incontinence
- People with neurological conditions, such as Parkinson's disease or multiple sclerosis
- Individuals with limited mobility or cognitive impairment
- Those who recently started a new medication or had their dosage changed
Medications That Can Contribute to Incontinence
There are certain medications and prescriptions that you may need to take for specific health conditions, but some of them may cause or contribute to incontinence as a side effect. Depending on how they work, medications may increase urine production, relax the muscles that help control urination, interfere with nerve signals between the brain and bladder, or make it more difficult to recognize the need to use the bathroom. Below are some of the most common medications associated with urinary incontinence.
Diuretics
Diuretics are commonly prescribed to treat high blood pressure, heart failure, and swelling caused by fluid retention. They work by helping the kidneys remove excess sodium and water from the body, which naturally increases urine production.
Since they cause the body to produce more urine, diuretics can make it difficult to reach the bathroom in time, especially for people who already have an overactive bladder or reduced mobility. As a result, they may worsen symptoms such as:
- Increased urinary frequency
- Sudden urinary urgency
- Urge incontinence
- Nighttime urination (nocturia)
Blood Pressure Medications
Certain blood pressure medications may also contribute to bladder control problems, although the effects vary depending on the type of medication. For example, alpha-blockers relax smooth muscle to improve urine flow in people with enlarged prostates. However, they can also relax the muscles in the bladder neck and urethra, making it more difficult to prevent urine leakage. This may increase the risk of stress urinary incontinence, particularly in women. Alpha-adrenergic may also increase the risk of urine leaks in people with stress incontinence.
Some calcium channel blockers may also reduce bladder muscle contractions, making it harder to completely empty the bladder. Over time, this can lead to urinary retention and, in some cases, overflow incontinence, where small amounts of urine leak because the bladder becomes overly full.
Antidepressants
Antidepressants may affect bladder function by altering the nerve signals and muscle activity involved in urination, but the effects depend on the specific drug. Some medications may relax the bladder or urethral muscles, increasing the likelihood of urine leakage, while others may make it more difficult to empty the bladder completely. Certain antidepressants may also cause sedation, making it harder to recognize the need to urinate promptly.
Although these side effects are not common for everyone, it's important to speak with your doctor if bladder symptoms begin after starting or changing an antidepressant.
Sedatives and Sleeping Medications
Sedatives, anti-anxiety medications, and sleep aids can reduce alertness and slow reaction times. While they don't directly affect the bladder itself, they may make it harder to wake up when the bladder is full or reach the bathroom quickly enough.
This can increase the risk of:
- Functional incontinence
- Bedwetting (nocturnal enuresis)
- Falls while rushing to the bathroom, particularly in older adults
If you experience adverse effects from these types of medications, your doctor may be able to prescribe an alternative brand to help reduce the risk of urinary incontinence while fulfilling the intended benefits.
Muscle Relaxants
Muscle relaxants are prescribed to relieve muscle spasms and stiffness, but they can also relax muscles involved in bladder control. In some cases, this reduced muscle tone may contribute to urine leakage, especially in people who already have weakened pelvic floor muscles or stress incontinence. These medications may also cause drowsiness or dizziness, making it more difficult to respond quickly when the urge to urinate occurs.
Opioid Pain Medications
Prescription opioids, such as those used to treat moderate to severe pain, are more commonly associated with urinary retention than with urinary incontinence. They can reduce bladder muscle contractions, making it difficult to fully empty the bladder.
When urine remains in the bladder, it can eventually lead to overflow incontinence. Opioids can also cause constipation, which places additional pressure on the bladder and may worsen urinary symptoms.
Antihistamines and Cold Medications
Many allergy medications and over-the-counter cold remedies contain antihistamines, which can interfere with normal bladder emptying by relaxing the bladder muscle and tightening the bladder outlet. This may increase the risk of urinary retention, particularly in older adults and people with enlarged prostates. Some combination cold medications may also contain decongestants, which can further make urination more difficult.
Parkinson's Disease and Other Neurological Medications
Medications used to treat neurological conditions such as Parkinson's disease may also influence bladder function, especially anticholinergics. While many help improve movement and muscle control, they can sometimes alter the nerve signals involved in bladder storage and emptying.
In some people, these medications may contribute to:
- Increased urinary urgency
- More frequent urination
- Difficulty emptying the bladder
- Episodes of urge incontinence
Since neurological disorders themselves often affect bladder function, it can sometimes be difficult to determine whether the condition, the medication, or a combination of both causes symptoms.
What Should You Do If Medications Are Worsening Your Incontinence?
If you notice that you're experiencing leakage of urine after starting a new medication, it can be tempting to stop taking it. However, you should never stop taking a prescribed medication because you suspect it is contributing to urinary incontinence. Many medications are essential for managing serious health conditions, and stopping them abruptly can be dangerous.
For any new or worsening bladder symptoms after starting a medication or changing your dosage, talk to your doctor. They can review your medications, determine whether they may be contributing to your symptoms, and recommend safer alternatives or adjustments if appropriate.
Treatment for Urinary Incontinence
While there are some medications that can cause UI, there are also several treatment options that can help address symptoms. Some of the most impactful include:
- Lifestyle changes (weight loss, smoking cessation, and limiting bladder irritants)
- Bladder training and scheduled bathroom visits
- Kegels to strengthen the pelvic floor muscles
- Physical therapy for pelvic floor muscle strengthening
- Adjusting or changing medications that contribute to incontinence (under a healthcare provider's guidance)
- Prescription medications for an overactive bladder
- Vaginal estrogen therapy (for some postmenopausal women)
- Medical devices, such as pessaries
- Bulking agent injections around the urethra
- Botox® injections into the bladder muscle
- Nerve stimulation therapies
- Catheterization (for certain cases of overflow incontinence)
- Surgery, such as sling procedures or bladder neck suspension
- Absorbent products, including pads, protective underwear, and other incontinence supplies for day-to-day management
Adjusting your treatment plan may be enough to help mitigate adverse reactions from medications and can greatly improve your quality of life. Byram Healthcare also carries a range of high-quality incontinence products to help maximize comfort and minimize the risk of leaks.
