I’m on the other side, I work for an orthopedic surgeon
It’s not one of the standard meds we give after surgery but it’s definitely one we have given
It’s a muscle relaxer so it would help with the pain somewhat but it’s not meant to be doing the heavy lifting in that department, likely they’re giving the meds to help with muscle issues related to surgery like spasms or like retractions
It can make you drowsy, in fact some people use them to help sleep through the night for for short terms
You don’t have to take it with food
The default template I have to write a script for muscle relaxers is to take it before bed
Hope any of this helps and hope everything is going well
