My doctor prescribed Fosamax ™, taken once a week, for osteoporosis which I took for a year, paying my insurance company copay. When this first insurance company went into lengthy contractual debate with the clinic I was going to, we switched to another insurance company. When I went to get my prescription filled, this new company forced me to switch to another brand, Actonel, to be taken daily. When I asked my doctor about this she was not happy but told me she had to go along with the change from what she had prescribed – that health insurance companies had the power to change doctor’s prescriptions! I did the regular channels laid out by my insurance to request they uphold my physician’s orders of the weekly meds and was rebuffed by their statement that that was their policy, take it or leave it, in so many words. I’m still amazed that they can get away with this!
