I was at the emergency room last night and they gave me medicine one of them needs a prior authorization how can I get that or something that I can get filled

Call back out there and tell them what's going on and ask them if they can call in either a generic form of the medicine or a different kind of medication

What Hank says, or you can call your family Dr, if you have one and they will fix it. At least they do at the drs office I work for. Might be best this soon to call the ED back being its still fresh and they know what's going on. Your pharmacy should do that for you. Good luck!
