Myrbetriq is an overactive bladder medication used to improve symptoms such as urinary incontinence and frequent or urgent urination. The main active ingredient in Myrbetriq is mirabegron, which belongs to the drug class urinary antispasmodics. This medication can be used alone, but it is often combined with solifenacin succinate. In addition to overactive bladder, Myrbetriq is also indicated for treating neurogenic detrusor overactivity in children three and up.

How long does it take for Myrbetriq to work?

This medication usually begins to work within three to four hours. After taking Myrbetriq, the muscles in the bladder will begin to relax. Still, mirabegron is typically used for the long-term management of overactive bladder, so you may not see significant improvements in symptoms until four to eight weeks into your treatment period. Continue checking in with your healthcare provider, informing your doctor if symptoms do not improve or worsen.

What is Myrbetriq prescribed for?

Myrbetriq (mirabegron) is approved for two primary uses. First, Myrbetriq may be used to treat symptoms of overactive bladder (OAB). This drug relaxes the muscles surrounding the bladder to alleviate spasms and incontinence. The second indication for mirabegron is for treating neurogenic detrusor overactivity in children. However, this drug is not approved for use in children under the age of 3. Special cases may occur, so talk to your doctor to ensure Myrbetriq is right for you or your child.

How long does mirabegron stay in your system?

Myrbetriq is a long-term treatment, so you should not stop taking this drug without first notifying your physician. Mirabegron stays in an adult’s system for around 10 days, but it may clear out of a child’s body within six. Make sure you are approved to stop taking mirabegron before doing so to avoid symptoms coming back.
