Baclofen (baclofen) — Uses, Dosage, Side Effects & Safety

Drug class: Skeletal muscle relaxant (centrally acting)

Overview

Baclofen is a prescription medicine used to treat muscle spasms caused by conditions such as multiple sclerosis, spinal cord injuries, or other neurological disorders. It helps relax muscles and reduce pain, stiffness, and muscle tightness. Baclofen works by acting on the central nervous system, specifically by stimulating GABA-B receptors in the spinal cord. This action decreases the transmission of nerve signals that cause muscle spasms. Patients should know that Baclofen may cause drowsiness or dizziness, especially when starting treatment or when the dose is increased. It is important to take Baclofen exactly as prescribed and not to stop taking it suddenly without consulting a healthcare provider, as this can lead to withdrawal symptoms.
