I just recently had a surgery and am prescribed5/325 mg oxycodone/acetaminophen for pain. As it's helping with the pain, it's been making me very nauseous and difficult to eat but I am eating. It's been giving me very bad anxiety and I am prescribed .5 mg alprazolam for anxiety by a separate dr to take as needed only. Is it ok to take a xanax while on the percocet? Please help..
