For those who are low income (too many of us), I just wanted to make sure you know about Patient Assistant Programs. These are programs designed to help with obtaining medications either free or at a significant discount direct from the manufacturer.
My doctor told me about it when I told her I couldn't afford the Advair she prescribed (discs are almost $300.00 which lasts less than a month). I went to their website, found the Patient Assistant Program information (it was well buried) and followed the instructions. Basically, all I had to do was fill out an online form, get an original prescription from my doctor for a 3-month supply with 3 refills (one years' worth of meds), and proof of income, either in the form of last years' tax return or a statement of income for the last complete month. I faxed everything in to them and 2 weeks later I received my first three months of Advair. That's $900.00 worth of meds and I'll receive 3 more of these packets for a total of $3600 in savings on medication I would never be able to afford.
This may or may not be common knowledge but, just in case you or someone you know is having problems obtaining medication, this might be the solution.
