The dosage is based on your medical condition and response to therapy.Your body will absorb this medication differently depending on whether you take it as a tablet or capsule, whether you take it with food or on an empty stomach, or if you sprinkle the contents of the capsule on food. Be sure to discuss this with your doctor to determine the best way to take your dose, especially when changes to your dose are being considered or if your doctor prescribes a different form of tizanidine (e.g., tablet or capsule).This medication may cause withdrawal reactions, especially if it has been used regularly for a long time or in high doses. In such cases, withdrawal symptoms (such as anxiety, tremor, increased blood pressure, heart rate and muscle tenseness) may occur if you suddenly stop using this medication.
