Myrbetriq Granules

Generic name: Mirabegron
Drug class: Urinary antispasmodics

Usage of Myrbetriq Granules

Mirabegron is used alone or together with other medicines (eg, solifenacin succinate) to treat the symptoms of an overactive bladder (OAB), such as incontinence (loss of bladder control), a strong need to urinate right away, or a frequent need to urinate. It is also used to treat neurogenic detrusor overactivity (NDO). Mirabegron works on the muscles of the bladder to increase the amount of urine your bladder can hold and prevent them from causing incontinence.

This medicine is available only with your doctor's prescription.
