Yes, it does. It's a muscle relaxer.
My neurologist told me zanaflex makes people feel very sleepy.
I am seeing my regular Dr. who but he specializes in Fibro.. And the pain medication really seemed to help lastnight, but this morning I am so sore.....I am waiting on the Dr's office to call in a refill of Cymbalta for me...... So right now I'm just relying on the Zanaflex.
I take 40mg on Cymbalta. I believe the Zanaflex is the same type medication. I can believe it knocked you out! Have you considered the new drug that was the first approved drug for fibro...Lyrica. You start slow, and work up to the dose that relieves your nerve pain. There are some side effects, and some people gain weight on it, but it has helped my fibro and diabetic neuropathy a lot. Is this a GP you are seeing, or a rheumatologist who specialises in fibro? A specialist would be best. Good luck.
