Indications
Myrbetriq (Mirabegron) is a prescription medication used to treat overactive bladders and urinary incontinence. It helps patients relieve their symptoms such as frequent urination and sudden urges to go to the bathroom. It is the first in a new class of drugs that work by selectively activating β3-adrenergic receptors found in the bladder. It works by blocking a certain type of receptor called the muscarinic receptor in the bladder that is involved in OAB symptoms.
It can be used alone or together with other medicines (e.g., 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.
Myrbetriq is available in two strength 25 mg and 50 mg tablet both taken by mouth. These forms are both extended releases, meaning the medication is slowly released into the body over time after taking a dose.
Uses and Dosage
Patients should take Myrbetriq strictly according to the instructions of a physician or healthcare professional. It is important to swallow the tablets whole with a full glass of water; crushing or chewing the tablets may reduce the effectiveness of the medication.
The recommended starting dose of Myrbetriq (mirabegron) is 25 mg taken orally once daily, either with or without food. However, children must take Myrbetriq with food. Generally, efficacy can be expected within 8 weeks of treatment, and the dose may be increased to 50 mg once daily if necessary. It is important to take Myrbetriq exactly as prescribed and to swallow the tablets whole; do not crush, divide, or chew the tablets.
