Detrol reduces spasms of the bladder muscles.

Detrol is a prescription medicine used to treat symptoms of overactive bladder in adults, including:

• urge urinary incontinence: a strong need to urinate with leaking or wetting accidents;
• urgency: a strong need to urinate right away; or
• frequency: urinating often.

Detrol LA capsules did not help the symptoms of overactive bladder when studied in children.

Do not take Detrol if you are allergic to tolterodine or or fesoterodine (Toviaz), if you have untreated or uncontrolled narrow-angle glaucoma, or if you have a blockage of the urinary tract, stomach, or intestines.

Before you take Detrol, tell your doctor if you have kidney or liver disease, glaucoma, myasthenia gravis, or a personal or family history of "Long QT syndrome."

Do not crush, chew, break, or open a Detrol LA controlled-release capsule. Swallow it whole. Breaking or opening the pill may cause too much of the drug to be released at one time.

Detrol may impair your thinking or reactions. Be careful if you drive or do anything that requires you to be alert. Drinking alcohol can increase some of the side effects of Detrol.

There are many other drugs that can interact with Detrol. Tell your doctor about all medications you use. This includes prescription, over the counter, vitamin, and herbal products.
