Nasal Imitrex would cost ? if you had to buy it retail with out health care. I would like an estimate of the cost to fill a script for nasal imitrex. My loved one had a horrific mirgraine, 13+ hours, and she could not take anything orally to recover from it. I was wondering, if we had a script and it happend again, we might fill it and pay for it all out of pocket. I would like to know an estiamte of what that cost would be, thank you.
