Dosage and strength
Mirabegron comes as 25mg and 50mg slow-release tablets.
The usual dose is 50mg, taken once a day.
If you have kidney or liver problems, your doctor may recommend a lower dose of 25mg taken once a day.
How to take it
You can take mirabegron at any time, but take it at the same time each day.
Swallow the tablets whole with a drink of water. Do not chew or crush them.
You can take mirabegron with or without food.
How long to take it for
Usually, treatment with mirabegron is long term.
Do not stop taking it without talking to your doctor first. Your symptoms may come back or get worse.
However, if you no longer have bladder problems, your doctor will advise you to stop taking it.
If you forget to take it
If you forget to take a dose of mirabegron, take it as soon as you remember unless your next dose is due in less than 6 hours. In this case skip the missed dose and take your next one at the usual time.
Do not take 2 doses to make up for a missed dose.
If you forget doses often, it may help to set an alarm to remind you. You could also ask your pharmacist for advice on other ways to help you remember to take your medicine.
If you take too much
If you take more than your prescribed dose of mirabegron, it's unlikely to harm you.
If you take an extra dose you might get some of the common side effects, such as increased heart rate, or headache and dizziness.
