> I wonder how that latter price compares to the price in the US
My guess is not favourably for the US. My wife was diagnosed with MS about a year before we moved to America and, since I knew we were moving and was thinking about insurance, I asked the pharmacist once what they billed the govt per dose (monthly). We paid $40 out of pocket and the govt paid $1300 AUD.
Our insurance in the US pays nearly $10k USD/m for the same drug.
