Baclofen is a muscle relaxer and an antispasmodic agent.

Baclofen is used to treat muscle pain, spasms, and stiffness in people with multiple sclerosis or spinal cord injury or disease.

Baclofen is given intrathecally (directly into the spinal cord) or orally (by mouth).

Before you begin taking baclofen, and each time you get a refill, read the Patient Information Leaflet if it is available from your pharmacist. If you have any concerns, consult your doctor or pharmacist.
