Q:

Is it possible to use Emgality to treat migraines after they start?

Anonymous

A:

Migraine symptoms are supposed to be treated once they start. Emgality is approved for preventing headaches.

Emgality works by blocking the action of a protein called calcitonin gene-related peptide (CGRP). CGRP can play a role in causing migraine headaches. By stopping CGRP from working, Emgality helps prevent migraine headaches. But the drug isn’t likely to relieve symptoms once you already have a migraine headache.

Talk to your doctor about the treatment of migraines. They can suggest the best treatment for you based on your health. They may recommend over-the-counter drugs. They may suggest some non-medication treatments, such as applying an ice pack or staying quiet until your symptoms improve.
