Top Myrbetriq FAQs Answered for 2024

Myrbetriq, a medication primarily used to treat overactive bladder (OAB), has gained significant attention for its efficacy and unique mechanism of action. As we move into 2024, many patients and healthcare providers have questions about this medication. Here are the top frequently asked questions (FAQs) about Myrbetriq answered.

1. What is Myrbetriq?

Myrbetriq (mirabegron) is a prescription medication used to treat adults with overactive bladder (OAB) with symptoms of urge urinary incontinence, urgency, and urinary frequency. It belongs to a class of drugs known as beta-3 adrenergic agonists, which work by relaxing the bladder muscle during the storage phase of the bladder fill-void cycle. This increases the bladder’s capacity and reduces the symptoms of OAB.

2. How does Myrbetriq work?

Myrbetriq works by stimulating beta-3 adrenergic receptors in the bladder. Unlike antimuscarinic drugs, which target the bladder’s nerve signals to reduce muscle contractions, Myrbetriq directly relaxes the bladder muscle, allowing it to store more urine. This helps reduce the frequency and urgency of urination, as well as episodes of incontinence.

3. Who can benefit from taking Myrbetriq?

Myrbetriq is primarily prescribed for adults experiencing symptoms of overactive bladder, including urgency, frequency, and urge urinary incontinence. It is particularly beneficial for those who have not responded well to antimuscarinic medications or who cannot tolerate their side effects. However, a healthcare provider should evaluate each patient’s specific situation to determine if Myrbetriq is the right treatment option.

4. What are the common side effects of Myrbetriq?

Like all medications, Myrbetriq can cause side effects. Common side effects include increased blood pressure, common cold symptoms (nasopharyngitis), urinary tract infection, headache, and gastrointestinal issues such as constipation or diarrhea. It is important to discuss any side effects experienced with a healthcare provider, as they can offer solutions or adjust the treatment plan if necessary.

5. Are there any serious side effects associated with Myrbetriq?

While serious side effects are less common, they can occur. These may include severe hypertension, urinary retention, and allergic reactions such as rash, itching, or swelling. Patients should seek immediate medical attention if they experience symptoms of a severe allergic reaction or any unusual changes in their health.

6. How should Myrbetriq be taken?

Myrbetriq is typically taken once daily, with or without food. It is important to swallow the tablet whole with water and not to crush, chew, or break it. Consistency in taking the medication at the same time each day helps maintain an even level in the bloodstream, optimizing its effectiveness.

7. Can Myrbetriq be used in combination with other medications?

Yes, Myrbetriq can be used in combination with other medications, such as antimuscarinics, to manage OAB symptoms more effectively. However, it is crucial to inform the healthcare provider about all the medications currently being taken, including over-the-counter drugs and supplements, to avoid potential interactions.

8. How long does it take for Myrbetriq to show results?

The onset of relief from OAB symptoms can vary among individuals. Some patients may start to notice improvements within a few weeks, while for others, it may take several months. It is important to continue taking the medication as prescribed and to have regular follow-ups with the healthcare provider to assess its effectiveness and make any necessary adjustments.

9. Is Myrbetriq safe for long-term use?

Clinical studies and real-world data suggest that Myrbetriq is safe for long-term use when taken as prescribed. Regular monitoring by a healthcare provider is essential to ensure its continued effectiveness and to manage any potential side effects.

10. Are there any contraindications for taking Myrbetriq?

Myrbetriq is contraindicated in patients with severe uncontrolled hypertension, as it can increase blood pressure. It is also not recommended for patients with known hypersensitivity to mirabegron or any of the inactive ingredients in the tablet. A thorough medical history and evaluation by a healthcare provider are crucial before starting Myrbetriq.

11. Can pregnant or breastfeeding women take Myrbetriq?

The safety of Myrbetriq in pregnant or breastfeeding women has not been well established. It is important for women who are pregnant, planning to become pregnant, or breastfeeding to discuss the potential risks and benefits with their healthcare provider before starting the medication.

12. How is Myrbetriq different from other OAB treatments?

Myrbetriq’s unique mechanism of action distinguishes it from antimuscarinic drugs, which have been the traditional treatment for OAB. By targeting the beta-3 adrenergic receptors, Myrbetriq offers an alternative for patients who may not tolerate or respond well to antimuscarinics, providing a different therapeutic approach to managing OAB symptoms.


Myrbetriq continues to be a valuable treatment option for overactive bladder, offering a unique mechanism of action and a favorable side effect profile for many patients. Understanding its uses, benefits, and potential risks can help patients and healthcare providers make informed decisions about managing OAB in 2024 and beyond. Always consult with a healthcare professional for personalized advice and treatment plans.
