Update: I took my scrip to the Walgreens pharmacy, a bit of heaven for those of us accustomed to the third world country that is the Duane Reade pharmacy experience. As it turns out, Imitrex has lowered its price to match the price of the generic.
I decided to stick with the name brand after reading a few online comments from people who've tried the generic and found it doesn't work as well. I can't say I'm that surprised, as the generic manufacturing company is named Dr. Reddy's Laboratories, which just reminds me of Dr. Funke's 100% Natural Good-Time Family-Band Solution from "Arrested Development," so I just cannot take it seriously. But maybe I just need to take an Euphorazine.
