When two 4 mg dosage tablets were administered with zanaflex food, the mean maximal plasma concentration was dosage dosage increased by zanaflex approximately 30, and the median time to peak plasma concentration was increased by 25 minutes, to 1 hour and 25 minutes. The dosage Cmax, AUC, and half-life of dosage tizanidine increased by 12- fold, 33-fold, and 3-fold, respectively. Tell patients that they should zanaflex not dosage suddenly discontinue Zanaflex, because rebound hypertension and tachycardia may occur.
