http://www.medications.com/effect/view/24538 Given Zanaflex after 6 back surgeries. Dosage take 2 tabs (4mg) 4 times a day. Total dosage 24hrs (8mg x 4 = 32mg.) This seems high to me. What happens is my stomach does not digest food, mobility slows way down; can not urinate, pass gas.

I have instructions to take 1/2 as needed thoughout the day not to exceed 4mg per day total. It is great for helping me sleep but if I take too much at bedtime-then I have the hallucinations.
