Why is this medication prescribed?
Mirabegron is used alone or in combination with solifenacin (Vesicare) to treat overactive bladder (a condition in which the bladder muscles contract uncontrollably and cause frequent urination, urgent need to urinate, and inability to control urination) in adults. It is also used to treat neurogenic detrusor overactivity (a bladder control condition caused by brain, spinal cord or nerve problem) in children 3 years of age and older. Mirabegron is in a class of medications called beta-3 adrenergic agonists. It works by relaxing the bladder muscles to prevent urgent, frequent, or uncontrolled urination.
How should this medicine be used?
Mirabegron comes as an extended-release (long-acting) tablet and as an extended-release suspension to take by mouth. The tablets are usually taken with or without food once a day in adults and with food once a day in children. The suspension is usually taken with food once a day. Take mirabegron at around the same time every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take mirabegron exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Swallow the extend-release tablets whole with water; do not split, chew, or crush them.
It is important to use the oral dosing device to accurately measure and take your dose of the extended-release suspension. Ask your pharmacist for a device if it was not provided. Shake the bottle vigorously for 1 minute, then let it stand for 1 to 2 minutes until the foam on top of the suspension is gone. If the granules have not mixed well, shake the bottle vigorously again for 1 minute and let it stand until the foam is gone. Use the oral dosing device to draw up the suspension and ignore any bubbles in your measurement. Do not save the dose in the dosing syringe for later; use within 1 hour after preparation. After each use, wash the oral dosing device with mild soap, then rinse with tap water and allow it to air dry. If the suspension is not used for 2 or more days, shake the bottle for 1 minute each day.
Your doctor may increase your dose, depending on how well your symptoms are controlled and the side effects you experience. Talk to your doctor about how you are feeling during your treatment with mirabegron.
Mirabegron controls the symptoms of overactive bladder or neurogenic detrusor overactivity, but does not cure these conditions. It may take 8 weeks or longer before you feel the full benefit of mirabegron. Continue to take mirabegron even if you feel well. Do not stop taking mirabegron without talking to your doctor.
