My co-pay was not the problem, it was the insurance company limiting my triptan usage to 4 a month. Merck paid for my medication when I was uninsured, but now I am insured and have not tried applying for a hardship through them (yet). I did however finally order the generic rizatriptan through a Canadian pharmacy and was please to find that for me it does work and the cost with no insurance is almost the same as my co-pay alone for 16 pills. In other words I am paying about $3.50 per pill in CA for generic, for what would cost me $33 per pill for brand name Maxalt in the US. I am so pleased. It does take about 2 and a half weeks from the time I order to get them, but other than that I have no problems. They do let you know that up front though.
