Baclofen Oral (patient information)

Why this medication is prescribed
Baclofen acts on the spinal cord nerves and decreases the number and severity of muscle spasms caused by multiple sclerosis or spinal cord diseases. It also relieves pain and improves muscle movement.

This medication is sometimes prescribed for other uses; ask your doctor or pharmacist for more information.

How this medication should be used
Baclofen comes as a tablet to take by mouth. It usually is taken three times a day at evenly spaced intervals. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take baclofen exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor. This drug must be taken regularly for a few weeks before its full effect is felt.

Continue to take baclofen even if you feel well. Do not stop taking baclofen without talking to your doctor, especially if you have taken large doses for a long time. Your doctor probably will want to decrease your dose gradually.

Special precautions
Before taking baclofen:


 * tell your doctor and pharmacist if you are allergic to baclofen or any other drugs.

 * tell your doctor if you have or have ever had kidney disease, epilepsy, ulcers, a stroke, a rheumatic disease, cerebral palsy, Parkinson's disease, or a psychiatric condition.
 * tell your doctor if you are pregnant, plan to become pregnant, or are breast-feeding. If you become pregnant while taking baclofen, call your doctor immediately.
 * you should know that this drug may make you drowsy. Do not drive a car or operate machinery until you know how baclofen affects you.
 * remember that alcohol can add to the drowsiness caused by this drug.
