General Info:

Zanaflex is a short-acting muscle relaxant. It works by blocking nerve impulses (pain sensations) that are sent to your brain. Zanaflex is used to treat spasticity by temporarily relaxing muscle tone.

Zanaflex is a short-acting medication that should be taken only for daily activities that require relief from muscle spasticity.

Do not use Zanaflex at a time when muscle tone is needed to assure safe balance and movement for certain activities. In some situations, it may endanger your physical safety to be in a state of reduced muscle tone.

Do not take more than three doses (36 mg) of Zanaflex in a 24-hour period. Too much of this medication can damage your liver. Zanaflex can cause side effects that may impair your thinking or reactions.
