is prescribed for people with multiple sclerosis, spinal cord injuries,
and other disorders that produce protracted muscles spasms. The effect
of the drug peaks 1 to 2 hours after each dose and is gone within 3
to 6 hours, so it's best to schedule doses for shortly before the daily
activities when relief of spasticity is most important.
