Tizanidine is a short-acting medication, and its effects will be most noticeable between 1 and 6 hours after you take it. This medication should be taken only for daily activities that require relief from muscle spasticity.
In most cases, you may take up to three doses in one day if needed. Allow 6 to 8 hours to pass between doses.

Switching between tizanidine tablets and capsules, or changing the way you take it with regard to eating, can cause an increase in side effects or a decrease in therapeutic effect. Follow your doctor's instructions carefully. After making any changes in how you take tizanidine, contact your doctor if you notice any change in how well the medicine works or if it causes increased side effects.

You may have withdrawal symptoms such as dizziness, fast heart rate, tremors, anxiety, and increased spasticity when you stop using tizanidine after using it over a long period of time.
