Why is this medication prescribed?
Baclofen is used to treat pain and certain types of spasticity (muscle stiffness and tightness) from multiple sclerosis, spinal cord injuries, or other spinal cord diseases. Baclofen is in a class of medications called skeletal muscle relaxants. Baclofen acts on the spinal cord nerves and decreases the number and severity of muscle spasms caused by multiple sclerosis or spinal cord conditions. It also relieves pain and improves muscle movement.
How should this medicine be used?
Baclofen comes as a tablet and a solution (liquid) to take by mouth. It usually is taken 3 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.
Use an oral syringe (measuring device) to accurately measure and take your dose of baclofen solution. Ask your pharmacist for an oral syringe if one is not included with your medication.
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. Abruptly stopping this medication can cause seizures, fever, confusion, muscle stiffness, or hallucinations. Your doctor probably will want to decrease your dose gradually.
Other uses for this medicine
This medication is sometimes prescribed for other uses; ask your doctor or pharmacist for more information.
What special precautions should I follow?
Before taking baclofen,
- tell your doctor and pharmacist if you are allergic to baclofen, any other medications, or any of the ingredients in baclofen tablets and oral solution. Ask your pharmacist for a list of the ingredients.
- tell your doctor and pharmacist what other prescription and nonprescription medications, vitamins, nutritional supplements, and herbal products you are taking or plan to take. Be sure to mention any of the following: antidepressants, medications for anxiety, medications for mental illness, medications for seizures, sedatives, sleeping pills, or tranquilizers. Your doctor may need to change the doses of your medications or monitor you carefully for side effects.
- tell your doctor if you have or have ever had epilepsy, a stroke, a rheumatic disease, cerebral palsy, Parkinson's disease, a psychiatric condition such as schizophrenia or a confusional state, or kidney disease.
- 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 baclofen may make you drowsy. Do not drive a car or operate machinery until you know how this medication affects you.
- ask your doctor about the safe use of alcoholic beverages while you are taking baclofen. Alcohol can make the side effects from baclofen worse.
What should I do if I forget a dose?
Take the missed dose as soon as you remember it. However, if it is almost time for the next dose, skip the missed dose and continue your regular dosing schedule. Do not take a double dose to make up for a missed one.
What side effects can this medication cause?
Baclofen may cause side effects. Tell your doctor if any of these symptoms are severe or do not go away:
- difficulty falling asleep or staying asleep
- frequent urination
Some side effects can be serious. If you experience either of the following symptoms, call your doctor immediately:
- seeing things or hearing voices that do not exist
If you experience a serious side effect, you or your doctor may send a report to the Food and Drug Administration's (FDA) MedWatch Adverse Event Reporting program online (http://www.fda.gov/Safety/MedWatch) or by phone (1-800-332-1088).
What should I know about storage and disposal of this medication?
Keep this medication in the container it came in, tightly closed, and out of reach of children. Store the tablets at room temperature and away from excess heat and moisture (not in the bathroom). Store the oral solution in the refrigerator.
It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. http://www.upandaway.org
Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. See the FDA's Safe Disposal of Medicines website (http://goo.gl/c4Rm4p) for more information if you do not have access to a take-back program.

What other information should I know?
