I have suffered migraines my whole life. The current medications covered by my insurance (emitrex, maxalt) give me horrible side effects. The newer prophylactic migraine medications like Emgality, Amovig are not covered. They are in a family of drugs called calcitronin gene related peptide antagonists CGRP inhibitors. I can't afford any of these new wonder drugs without insurance coverage. I am new to the "grey research drugs" . Does anyone know of a source for any research CGRP antagonist drugs?
