Methocarbamol is approved for several medical uses, including:

1. Muscle Spasms: It is commonly prescribed to alleviate muscle spasms resulting from injuries, strains, or other musculoskeletal conditions.
2. Pain Relief: Methocarbamol can help reduce pain associated with muscle injuries or conditions like back pain.

How It Works

Methocarbamol works by depressing the central nervous system, which helps to relax muscles. In simpler terms, it alters the way the brain and spinal cord send messages to the muscles, reducing the feeling of tightness and discomfort. This action helps to ease muscle spasms and allows for better movement and function.

• Pediatric Patients: For children aged 16 years and older, the adult dosage applies. For younger children, the dosage is determined by a healthcare provider based on weight and condition.
