Methocarbamol Tablet

Detail Description

What is methocarbamol?

Methocarbamol is a muscle relaxer. It works by blocking nerve impulses (or pain sensations) that are sent to your brain.

Methocarbamol is used together with rest and physical therapy to treat skeletal muscle conditions such as pain or injury.

Methocarbamol injection is sometimes used in the treatment of tetanus, (lockjaw) which causes painful tightening of the muscles.
