Aimovig® (Erenumab) Auto-Injector Pen
Aimovig® (erenumab) is a prescription monoclonal antibody designed to help prevent migraine attacks in adults. It works by blocking the calcitonin gene-related peptide (CGRP) receptor, a key pathway involved in migraine development. The medication is supplied as a single-use prefilled auto-injector pen for convenient once-monthly self-administration.
