How to use tolterodine oral
Read the Patient Information Leaflet if available from your pharmacist before you start using tolterodine and each time you get a refill. If you have any questions, ask your doctor or pharmacist.
Take this medication by mouth with or without food as directed by your doctor, usually once a day. Swallow the medication whole with a full glass of liquid. Do not crush or chew the medication. Doing so can destroy the long action of the drug and may increase side effects.
Use this medication regularly to get the most benefit from it. To help you remember, use it at the same time each day. The dosage is based on your medical condition (especially kidney and liver disease), response to treatment, and other medications you may be taking. Be sure to tell your doctor and pharmacist about all the products you use (including prescription drugs, nonprescription drugs, and herbal products). Ask your doctor or pharmacist for more details.
Do not increase your dose or take this medication more often than directed. Your condition will not improve any faster and your risk of serious side effects may be increased.
Tell your doctor if your condition persists or worsens.
Dry mouth, dry eyes, headache, constipation, stomach upset/pain, dizziness, drowsiness, tiredness, or blurred vision may occur. If any of these effects persist or worsen, tell your doctor or pharmacist promptly.
To relieve dry mouth, suck (sugarless) hard candy or ice chips, chew (sugarless) gum, drink water, or use a saliva substitute.
To prevent constipation, eat dietary fiber, drink enough water, and exercise. You may also need to take a laxative. Ask your pharmacist which type of laxative is right for you.
Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.
