Take Zanaflex exactly as prescribed by your medical professional's advice.
Control the dose. A single dose of 8 mg of Tizanidine (generic form of Zanaflex) reduces the muscular tautness in patients with spasticity for a period of several hours. The effect peaks at approximately 1 to 2 hours and dissipates between 3 to 6 hours. Effects are depend on the dose.
Although single dose of less than 8 mg have not been demonstrated to be effective in controlled clinical studies, the dose-related nature of tizanidine's common adverse events make it prudent to begin treatment with single oral dose of 4 mg. Increase the dose gradually (2 to 4 mg steps) to optimum effect.
The dose can be repeated at 6 to 8 hour intervals, as needed, to a maximum of three dose in 24 hours. The total dose (per day) should not exceed 36 mg.
Experience with single dose exceeding 8 mg and dose (per day) exceeding 24 mg is limited. There is essentially no experience with repeated, single, day time doses larger than 12 mg or doses (per day) greater than 36 mg (injury is possible).
