Myrbetriq is a prescription medicine for adults used to treat overactive bladder (OAB) with symptoms of urgency, frequency and leakage.

What is Myrbetriq?

The first and only overactive bladder treatment in its class

If you're dealing with urges, frequency and leaks, ask your healthcare professional (HCP) if Myrbetriq® (mirabegron) may be an appropriate treatment option for you.

Myrbetriq (meer-BEH-trick) is a prescription medicine approved by the FDA (Food and Drug Administration) to treat overactive bladder (OAB) with symptoms of urgency, frequency and leakage in adults.

Myrbetriq is the first and only drug in its class for OAB.

Evaluated in clinical studies

The efficacy and safety of Myrbetriq have been evaluated in three 12-week studies and one long‑term (12-month) safety study.

In clinical trials, Myrbetriq was shown to be effective in treating symptoms of OAB within the first several weeks. Those taking Myrbetriq made fewer trips to the bathroom and had fewer leaks than those not taking Myrbetriq. Your results may vary.

If you have the overactive bladder symptoms of urgency, frequency and leakage, speak up and ask your doctor if Myrbetriq may be right for you.

How Myrbetriq Works

Myrbetriq works on a different pathway to increase bladder capacity

Your healthcare professional (HCP) may prescribe Myrbetriq® (mirabegron) for you because you have mentioned that you make too many trips to the bathroom, or have frequent leaks and accidents. Your HCP may also consider Myrbetriq as an option if you have tried other overactive bladder (OAB) management approaches that did not work for you. Before starting Myrbetriq, it's important that you understand how it works.

Myrbetriq is the only OAB treatment option in its class that targets the β3 pathway. When taken as directed, targeting this pathway can help relax the smooth muscle that surrounds the bladder and increase the bladder's ability to store urine. Watch the video below to learn more about how a healthy bladder functions, what causes OAB, and how Myrbetriq may help. After watching the video, if you still have questions or concerns, be sure to ask your HCP.
