DETROL LA

TOLTERODINE is used to treat overactive bladder. This medicine reduces the amount of bathroom visits. It may also help to control wetting accidents.

This medicine may be used for other purposes; ask your health care provider or pharmacist if you have questions.

Your health care provider needs to know if you have any of these conditions:

• difficulty passing urine
• glaucoma
• intestinal obstruction
• kidney disease
• liver disease
• memory problems like dementia
• an unusual or allergic reaction to tolterodine, other medicines, foods, dyes, or preservatives
• pregnant or trying to get pregnant
• breast-feeding

Do not take this medication if you are allergic to tolterodine, if you have untreated or uncontrolled narrow-angle glaucoma, or if you have a blockage of the urinary tract, stomach, or intestines.

Before taking tolterodine, tell your doctor if you have a personal or family history of "Long QT syndrome."

Do not crush, chew, break, or open a controlled-release capsule. Swallow the pill whole. It is specially made to release medicine slowly in the body. Breaking or opening the pill would cause too much of the drug to be released at one time.

Tolterodine can cause side effects that may impair your thinking or reactions. Be careful if you drive or do anything that requires you to be awake and alert.

Avoid drinking alcohol. It can increase some of the side effects of tolterodine.

There are many other medicines that can interact with tolterodine. Tell your doctor about all the prescription and over-the-counter medications you use. This includes vitamins, minerals, herbal products, and drugs prescribed by other doctors. Do not start using a new medication without telling your doctor. Keep a list with you of all the medicines you use and show this list to any doctor or other healthcare provider who treats you.

Side effects that you should report to your doctor or health care professional as soon as possible:

• allergic reactions like skin rash, itching or hives, swelling of the face, lips, or tongue
• confusion
• difficulty passing urine
• fast, irregular heartbeat
• hallucinations
• memory problems
• swelling in feet, hands

Side effects that usually do not require medical attention (report to your doctor or health care professional if they continue or are bothersome):

• changes in vision
• constipation
• dry eyes, mouth
• headache
• dizziness, drowsiness
• stomach upset

This list may not describe all possible side effects. Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088.

It may take 2 or 3 months to notice the full benefit from this medicine. Your health care professional may also recommend techniques that may help improve control of your bladder and sphincter muscles. These techniques will help you need the bathroom less frequently.

You may need to limit your intake tea, coffee, caffeinated sodas, and alcohol. These drinks may make your symptoms worse. Keeping healthy bowel habits may lessen bladder symptoms. If you currently smoke, quitting smoking may help reduce irritation to the bladder muscle.

You may get drowsy or dizzy. Do not drive, use machinery, or do anything that needs mental alertness until you know how this drug affects you. Do not stand or sit up quickly, especially if you are an older patient. This reduces the risk of dizzy or fainting spells.

Your mouth may get dry. Chewing sugarless gum or sucking hard candy, and drinking plenty of water, will help.

This medicine may cause dry eyes and blurred vision. If you wear contact lenses you may feel some discomfort. Lubricating drops may help. See your eye doctor if the problem does not go away or is severe.
