If you’re taking or considering Myrbetriq for bladder issues, it’s essential to be informed—not just about how it helps, but also about potential downsides. As an overactive bladder medication, Myrbetriq (mirabegron) offers relief by calming the bladder muscle, reducing sudden urges, leaks, and frequent trips to the bathroom.
However, no medication is without its risks. Understanding Myrbetriq side effects can help you use it more safely and have productive conversations with your healthcare provider.
What Is Myrbetriq Used For?
Myrbetriq is a bladder control medication prescribed to treat overactive bladder (OAB). It works differently from older treatments by targeting beta-3 receptors in the bladder, helping it store urine more effectively. This makes it helpful for people who struggle with urgency, incontinence, or frequent urination—especially those who didn’t do well with anticholinergic medications, which can cause dry mouth or drowsiness.
But just like with any medication, it’s important to weigh the benefits against the possible downsides.
Most Common Myrbetriq Side Effects
Not everyone experiences side effects, but some symptoms are commonly reported among users. Many are mild and temporary, especially as your body adjusts to the medication. Still, being aware of them helps you respond early if anything feels off.
Here are the most common side effects:
- Increased blood pressure – One of the most consistently reported side effects, especially in people already managing hypertension.
- Headache – Some patients notice recurring or dull headaches, particularly during the first few weeks.
- Constipation – Slower digestion or harder stools can occur, due to changes in bladder and bowel muscle tone.
- Dry mouth – Less common than with anticholinergics, but still a possible discomfort.
- Urinary tract infections (UTIs) – Though not caused directly by Myrbetriq, relaxed bladder function can contribute to UTI risk in some individuals.
Most people who experience these effects find them manageable or temporary, but it’s still smart to track them and mention them at follow-up visits.
Serious or Less Common Side Effects
Though rare, some side effects may be more serious. These aren’t common, but if they occur, you should contact a healthcare provider immediately.
- Fast or irregular heartbeat (palpitations)
- Chest pain or pressure
- Swelling of the face, lips, or throat—a potential sign of an allergic reaction
- Liver function changes, typically seen in blood work before symptoms show
People with preexisting heart issues should be especially cautious, as some of these symptoms could worsen underlying conditions.
Long Term Side Effects
As this medication is often taken for months or years, it’s worth considering the long-term side effects of Myrbetriq. While long-term studies are still ongoing, there are some known concerns to watch for with extended use.
These may include:
- Sustained high blood pressure – Even small increases over time can raise cardiovascular risk, particularly in older adults.
- Liver enzyme changes – These may not cause symptoms but can show up in regular blood tests.
- Heart rhythm changes – Though rare, this could be problematic for people with arrhythmia or other cardiac issues.
If you’re taking Myrbetriq long-term, your doctor may recommend periodic blood pressure checks, liver function tests, or heart monitoring, depending on your overall health.
Managing Myrbetriq Side Effects
If you’re starting Myrbetriq or noticing mild side effects, here are a few practical tips to manage them:
- Stay hydrated, especially if you’re experiencing dry mouth or constipation.
- Monitor your blood pressure regularly, even if you don’t have hypertension.
- Report any new or worsening symptoms early, especially heart-related signs or allergic reactions.
- Stick to consistent dosing times to help your body adjust and reduce the risk of missed doses or overlap.
Alternatives to Consider
If the side effects become disruptive, don’t feel stuck. There are other treatment paths for OAB:
- Anticholinergic medications like oxybutynin or tolterodine, though they may have their own side effects, especially cognitive ones in older adults.
- Combination therapy, such as Myrbetriq with solifenacin, may offer better symptom control with balanced side effects.
- Non-drug options, like pelvic floor physical therapy or bladder training, can be effective when done consistently.
The right solution depends on your symptoms, medical history, and lifestyle. Don’t hesitate to talk with your doctor about switching or adjusting your plan.
Takeaways
Myrbetriq side effects range from mild symptoms like headaches or constipation to more serious issues such as increased blood pressure or heart changes. While many tolerate the drug well, it’s important to be aware of both immediate and long-term side effects—especially if you’re taking it regularly.
As a trusted overactive bladder medication, Myrbetriq works for many people, but it’s not always the best fit for everyone. If you experience persistent discomfort or are concerned about how it’s affecting your health, there are other bladder control medication options worth exploring.
