Sad to say, I'm jealous your insurance covers 13! I'm dealing with the same thing. After I asked for nausea relief, Dr. Berntsen prescribed me 10 pills of Zofran, generic permitted, and one refill. I went to fill it, and learned that even for the generic form, ondansetron, my drug insurance (SilverScript, which I had chosen through my Medicare part D) required Prior Authorization before covering it, which would entail getting my surgeon to call them and justify it, and, even then, it could take 2 weeks for the insurance to decide on the request. I was having it filled in the evening, and had thrown up earlier that evening. I was desperate enough that I just paid for it all myself to get some relief. Just the 10 generic pills cost me $55-something at Dillon's (grocery store chain in Kansas) pharmacy. The pharmacist said the older alternatives to it were more likely to give side effects of drowsiness, dry mouth, and (something else I forgot). I am already spending so many hours a day in bed, that I don't want to take on additional sedation.
My mom mentioned that she got a MUCH better rate for a med (not for nausea) at Walgreens by buying their store membership card. I called up Walgreens to see if I could save by transferring the Rx to them. There, the 10 pills would have been over $100 (!) without the membership. The membership was $20, then the pills would have been $29.99, I think she said, BUT that they were forbidden from selling the membership card to people with Medicare Part D. So, I guess I just have to fork over the moolah at Dillon's. *insert steaming mad icon here, lol* I will think about asking the surgeon's office to try to help me get prior approval for the refill, although I am not sure I will need the refill.
Edited just to add this correction: I realized I already had refilled it, and paid cash the second time as well. I am unsure if I will seek assistance in getting a new Rx for nausea, be it ondansetron or a different med.
