Robaxin® (
methocarbamol) is a medication that is used to relieve pain associated with muscle spasms. The drug comes in the form of a tablet, as well as an injection -- the injectable form can also be used to treat tetanus (lockjaw). The medication is available in both brand-name and generic forms.
Robaxin tablets come in two different strengths: 500 mg (generic only) and 750 mg. For the first two to three days of treatment, the recommended starting dosage is 1500 mg (three 500-mg tablets or two 750-mg tablets) four times daily. Then, the dose should be lowered to 1500 mg twice daily, 1000 mg four times daily, or 750 mg six times daily.
The tablets are approved for individuals age 16 and older. The injectable form is not approved for children and adolescents under the age of 18, except to treat tetanus.
