Background

Methocarbamol was developed in the early 1950s as a treatment for muscle spasticity and the associated pain. It is a guaiacol glyceryl ether.

Methocarbamol tablets and intramuscular injections are prescription medicines indicated in the United States as an adjunct to rest, physical therapy, and other measures for the relief of discomforts associated with acute, painful musculoskeletal conditions. In Canada, methocarbamol can be sold as an over the counter oral medicine at a lower dose that may be combined with acetaminophen or ibuprofen. A combination product with acetylsalicylic acid and codeine is available in Canada by prescription.

Methocarbamol was FDA approved on 16 July 1957.
