Erenumab (brand name Aimovig) is a CGRP inhibitor that is approved for the treatment of migraines. It is administered via subcutaneous.

​

How does Aimovig (erenumab) work?

Erenumab works by blocking the action of the calcitonin gene-related peptide (CGRP), which is believed to play a role in the development of migraines. By blocking CGRP, erenumab can help reduce the frequency and severity of migraines.

​

What are the potential adverse effects and contraindications of erenumab?

Common adverse effects of erenumab may include injection site reactions, constipation, and muscle spasms. In rare cases, erenumab may cause serious allergic reactions, including anaphylaxis.

​

Erenumab should not be used in certain situations, such as during pregnancy or in people with a history of hypersensitivity reactions to the medication. It may also interact with certain medications, such as strong CYP3A4 inhibitors, so it's important to talk to your healthcare provider before taking erenumab for migraines.

​

What are CGRP inhibitors?

CGRP inhibitors are a class of medications that target the calcitonin gene-related peptide (CGRP), a molecule that is believed to play a role in the development of migraines. These medications work by blocking the action of CGRP or the CGRP receptor, which can help reduce the frequency and severity of migraines.

​

Who qualifies for CGRP inhibitor therapy under the PBS?

To qualify for CGRP inhibitor therapy under the PBS, patients must meet certain criteria, including:

• A diagnosis of chronic migraine or episodic migraine with at least four migraine days per month

• Previous failure of at least three other migraine prophylactic medications

• A positive response to a CGRP inhibitor trial

• Must be initially prescribed by a Neurologist
