Aimovig (erenumab-aooe) is a once-monthly, self-administered injection used to prevent migraines in adults. It helps prevent migraines before they start and reduces the number of migraine days per month. Aimovig is given as an injection under the skin (subcutaneous injection) using a single-dose prefilled autoinjector or a single-dose prefilled syringe.

How it works?

Aimovig works by blocking the effect of calcitonin gene-related peptide (CGRP), a small protein involved in migraines that increases during a migraine attack. By blocking CGRP, Aimovig stops interaction between CGRP and the CGRP receptor which helps to prevent migraines.
