Tolterodine 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.

Tolterodine is an antimuscarinic (anticholinergic) agent. It works by blocking a chemical that causes contractions of the bladder.

Do NOT use tolterodine if:

you are allergic to any ingredient in tolterodine or to fesoterodine
you have uncontrolled narrow-angle glaucoma, trouble urinating, or have slowed emptying of your stomach
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.
