A List of 50 Uncommon PREVENTIVE Migraine Medications
Posted on April 23 2023,

Below is a list of 50 PREVENTIVE migraine medications. This list is for chronic, refractory migraine patients that have not responded to first, second, or third-line preventive medications.
Many of these medications are not well-studied for migraine, may have serious adverse effects, and/or are not well-tolerated.
The ONLY purpose of this list is to start a conversation with your neurologist about the medications below. It is possible that some of these drugs will only be prescribed at a headache center specifically for chronic, refractory cases.
Every week, we will add a description to at least one medication with the available studies. Bookmark this page and come back to it on a semi-weekly basis. After every medication on this list is described with sources, we will move on to acute migraine medications that are less commonly used.
