I've been using Sumatriptan injectable ever since it became the generic for Imitrex. (at least 20 years) Now my pharmacy is unable to fill it. The pharmacist tells me it looks like the company, Prasco, is no longer making it. I was lucky that he got me a few doses, but they were the entire kit vs just the cartridges. That sure wastes a lot. Now he can't even get those. Switched pharmacies and they were able to get me two kits. Not sure what I'm going to do if that pharmacy can no longer order them. I've already checked with two other pharmacies nearby and both said they are unable to order it.
