Therapeutic class: Skeletal muscle relaxant acting via the central nervous system

Common strengths: 500 mg tablets are the most frequent; some products are available as 750 mg tablets.

Robaxin (methocarbamol) is prescribed for short-term relief of painful muscle spasm following strains, sprains, and other acute musculoskeletal events. Best outcomes usually combine medication with rest, graded movement and physiotherapy.

The the mechanism enabling it and operation

Methocarbamol depresses certain central nervous system pathways that contribute to muscle spasm. It does not directly act on the skeletal muscle fibers but reduces the neural input that sustains spasm and associated pain. A sedative effect is common and may partly account for symptom relief.
