Toviaz is used for:

Treating overactive bladder with symptoms of urinary frequency, urgency, and leakage. It may also be used for other conditions as determined by your doctor.

  • you are not able to empty your bladder (urinary retention)

  • you are taking a solid oral potassium product (eg, tablet)

Contact your doctor or health care provider right away if any of these apply to you.
