Uses
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). 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.

Before taking mirabegron:
- tell your doctor and pharmacist if you are allergic to mirabegron, any other medications, or any of the ingredients in mirabegron extended-release tablets. Ask your pharmacist or check the patient information for a list of the ingredients.

Your doctor may need to change the doses of your medications or monitor you carefully for side effects.
- tell your doctor if you have or have ever had bladder outlet obstruction (a blockage at the base of the bladder that stops urine from flowing freely out of the bladder and causes difficulty emptying the bladder and/or a weak urine stream), high blood pressure, or kidney or liver disease.
- tell your doctor if you are pregnant, plan to become pregnant, or are breastfeeding. If you become pregnant while taking mirabegron, call your doctor.

Dosage Of Mirabegron
Mirabegron comes as an extended-release (long-acting) tablet to take by mouth. It is usually taken with or without 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.
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 but does not cure the condition. 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.
Ask your pharmacist or doctor for a copy of the manufacturer’s information for the patient.

It is important for you to keep a written list of all of the prescription and nonprescription (over-the-counter) medicines you are taking, as well as any products such as vitamins, minerals, or other dietary supplements. You should bring this list with you each time you visit a doctor or if you are admitted to a hospital. It is also important information to carry with you in case of emergencies.
