After learning that my Valcyte (my nearly singular hope of living a life worth living) was going to be $6,000.00 a month WITH insurance, I called the manufacturer, Genentech, a division of McKesson and they, with no hassle whatsoever, gave me co-Pay card. With this card, I only pay $15 a MONTH for my Valcyte.
The least I can do is pass it on to my M.E. peeps!!
Good Luck, blessings, may the Force be with you and may you get the medicine you need:)
