My mom uses ergotamine (cafergot generic) to help control her migraines, but now she's having trouble finding the medication. Apparently there's some sort of shortage of an ingredient or something. She's really worried that she'll run out and there won't be anything to take its place (she can't take triptans or any of the other migraine abortives) -- anyone know about this problem, or how she can find a safe, legitimate source of the medication? Thanks!
