What is Ajovy (fremanezumab-vfrm)?
Ajovy (fremanezumab) is an FDA (U.S. Food and Drug Administration) approved medication manufactured by Teva Pharmaceuticals USA, Inc. It is a calcitonin gene-related peptide (CGRP) antagonist used for the preventive treatment of migraine (episodic migraine or chronic migraine) in adults. Ajovy can help to lower the number of migraine headache days you have each month by 1.5 to 2 days per month. Ajovy works by binding to the calcitonin gene-related peptide (CGRP) ligand preventing it from binding to its receptor.

Ajovy injections can be given into your abdomen, thighs, or upper arms. When using Ajovy take it out of the refrigerator and let it reach room temperature for 30 minutes before injecting.
