What is Aimovig?

Aimovig (full biological name erenumab-aooe) is a once-monthly, injectable medication that can be self-administered subcutaneously (under the skin) for the prevention of migraine in adults.

Aimovig works by blocking the effect of calcitonin gene-related peptide (CGRP) which is a small protein that is highly prevalent in the sensory nerves that supply the head and the neck. CGRP is involved in pain transmission and levels increase during a migraine attack. It may also play a causative role in the formation of migraine attacks. CGRP inhibitors are used to manage migraines and there are two types of CGRP inhibitors – monoclonal antibodies and CGRP receptor antagonists (gepants). Aimovig is a monoclonal antibody.

Aimovig was first FDA-approved on May 17, 2018. There is no Aimovig generic.

Before taking this medicine

Before you start using Aimovig, tell your healthcare provider about all your medical conditions, including if you are:

Pregnancy

It is not known if Aimovig will harm your unborn baby. However, having migraine headaches during pregnancy may cause complications such as preeclampsia (dangerously high blood pressure that can lead to medical problems in both mother and baby). The benefit of preventing migraines may outweigh any risks to the baby.

You may enroll yourself by calling 1-833-244-4083 or visiting https://www.genesispregnancyregistry.com/. Or you may talk to your doctor about how you can take part in this registry.
