Frequently asked questions

How do overactive-bladder medicines work?

Most relax the bladder muscle to reduce urgency and frequency. Newer ones (mirabegron) work differently with less dry mouth.

How long before they help?

It can take a few weeks. Bladder training and fluid habits alongside the medicine improve results.
