Hydrocodone?? Is this safe??

My jellybean is 8wks1dy and i was rushed to the hospital this morning due to horrible head, tooth and ear aches!! Come to find out I have an infected tooth! The dr gave me amoxicillin for the the infection and Hydrocodone for the pain. I ask the nurse was this safe and she kind of blew me off with a simple "sure" so I googled and im having mixed emotions about it! Some say its ok if its in a low dose my bottle says Hydrocodone/Acetaminophen 5MG/325MG!! Is this ok???
