NOTE: Because of its short duration, reserve tizanidine for activities and times when spasticity control is most important. Use tizanidine with caution when spasticity is beneficial to obtain increased function or to sustain posture and balance during movement.
Oral dosage Adults
SE: dry mouth, tiredness, and low energy. Dizziness and low blood pressure are also possible. Rare but serious tizanidine side effects include liver damage and hallucinations.
