Baclofen belongs to a class of medications called skeletal muscle relaxants. Baclofen is an antispasmodic agent that acts on spinal cord nerves and decreases the number and severity of muscle spasms in patients with certain conditions affecting the spinal cord.

Baclofen is used in adults and children at least 12 years old to treat certain types of spasticity (muscle stiffness and tightness) and muscle pain in people with multiple sclerosis or a spinal cord injury or other spinal cord diseases.

Baclofen relieves pain and improves muscle movement.

Do not use baclofen at a time when you need muscle tone for safe balance and movement during certain activities. Baclofen may make you drowsy. Do not drive or operate heavy machinery until you know how this medicine affects you.

Do not stop using this medicine suddenly, or you could have unpleasant withdrawal symptoms.

Ask your doctor about the safe use of alcoholic beverages while you are taking baclofen. Alcohol can make the side effects from baclofen worse.

Take baclofen exactly as prescribed by your doctor. Follow all directions on your prescription label and read all medication guides or instruction sheets. Your doctor may occasionally change your dose.

Shake the oral suspension (liquid).

Measure a dose with the supplied measuring device (not a kitchen spoon).

Shake and pour the entire oral granules packet to dissolve in your mouth or swallow whole at once, with or without liquids.

You may also mix the granules with liquids (milk, or apple juice) or soft food (apple sauce, yogurt, or pudding).

The oral granules can also be given through a feeding tube. Ask your doctor or pharmacist if you do not understand these instructions.

Call your doctor if your symptoms do not improve, or if they get worse.

You may have withdrawal symptoms if you stop using baclofen suddenly. Ask your doctor before stopping the medicine.

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.
