I wondering if Diltiazem is expensive from the compounding pharmacy. I was shocked when the rectiv cream turned out to be $500!!! (I did use the $40 coupon, but it's still crazy expensive.) And then I only used it 3 times before giving up entirely because the side effects incapacitated me. I really wish I knew someone I could pass that cream onto. I'm too frugal to just throw it out, so its sitting there in my drawer with the rest of my museum of stuff that didn't help my fissue pain.
