Key takeaways
Nurtec ODT (rimegepant) and Aimovig (erenumab) are both medications used to prevent migraines in adults. They belong to the same drug class, CGRP receptor blockers, but they have different forms and uses. Nurtec ODT is an orally disintegrating tablet that can also treat migraines when they occur (in addition to preventing migraines), while Aimovig is an injection used only for migraine prevention. Nurtec ODT is taken as needed for migraine attacks or every other day for prevention, whereas Aimovig is injected once a month. Nurtec ODT is available only as a brand-name medication, and it dissolves on the tongue, making it a good option for those who have trouble swallowing pills. Aimovig is also brand-name only and comes as a prefilled syringe or autoinjector. Common side effects of Nurtec ODT include nausea and stomach pain, while Aimovig can cause injection site reactions and constipation. Aimovig requires proper injection technique and should be stored in the refrigerator.
