Percocet, nausea, and wisdom teeth--HELP?

So I just had my wisdom teeth out yesterday. I am in sooooo much pain so the doctor prescribed percocet for the pain and some random anti-biotic to prevent infection. I am so nauseous from the percocet that I can't even take the anti-biotic. I have taken the percocet with food but the nausea just keeps persisting. Now because i can't take the anti-biotic I am afraid of getting an infection. Someone help please! I need to get rid of this nausea!!!!!! Thanks in advance.
