Findings

What does this study add?

• 14% of patients used ≥2 preventative migraine medications and, therefore, would be immediately eligible for CGRP mAbs treatment.
• An additional 17.6% tried one preventative medication and would need to fail another to be eligible.
• Less than one-third of patients in need of a migraine prevention treatment have received one.
• Patients are more likely to take migraine prevention medication if they have health insurance, higher migraine-related symptoms, greater migraine-related disability, and are diagnosed.
