What Causes Insomnia While On Tizanidine?

default
Posted on Fri, 27 Oct 2017
Question: I took one dose of Tizanidine HC 2mg yesterday at 1:00 pm. It relieved my muscle pain, but left me wide awake all night last night. I cannot take this again. But now I am wondering if I can take acetomenophen tonight around 7:00 pm without any risk of interaction.

Brief Answer:
no, no interaction

Detailed Answer:
First, the tizanidine might be a 12 hr drug but it certainly is not a 24 hr one, so it is gone. Second, tylenol is pretty safe drug unless you try to overdose on it.

So, no, no interaction.
