Mirabegron is a prescription medicine used to treat overactive bladder with symptoms of urgency (a strong need to urinate that is difficult to control), frequency (urinating often), and leakage (accidental urination due to a sudden or uncontrollable urge) in adults. Mirabegron works by relaxing the muscles around your bladder. 

This increases the volume of urine that your bladder can hold, and reduces your need to pass urine as frequently or as urgently.

Mirabegron (Myrbetriq) may also be used for purposes not listed in this medication guide.
