What is baclofen? 

Baclofen is a member of a group of medicines known as skeletal relaxants. Baclofen can be described as an antispasmodic drug that acts on spinal cord nerves and reduces the frequency and intensity of muscle spasms in patients suffering from specific conditions that affect the spinal cord.

Baclofen is prescribed to adults and children who are at least 12 to treat a variety of spasticity (muscle tightness and stiffness) and muscle pain for people suffering from MS, an injury to the spinal cord, or other diseases of the spinal cord.

Baclofen eases pain and increases muscle mobility.


Do not take baclofen when you require muscle strength for safety in balance and movement in specific tasks. Baclofen may make you feel sleepy. Don't drive or operate machines that are heavy until you understand what the effect of this medication is on you.

Don't stop taking the medicine abruptly, or you could experience uncomfortable withdrawal symptoms.

Discuss with your doctor the safety of drinking alcoholic drinks while taking baclofen. Alcohol can make the side effects of baclofen even more serious.
