Chronic Migraine and ketamine research
Where ketamine fits in the treatment of refractory chronic migraine and other chronic headache disorders.
Overview
Chronic migraine (≥15 headache days/month) is disabling and often resistant to standard preventives. A subset of patients exhausts conventional options and requires more aggressive interventions.
Conventional treatment
First-line includes lifestyle modification, trigger management, and preventive medications (topiramate, beta-blockers, anti-CGRP monoclonal antibodies, onabotulinum toxin A for chronic migraine specifically).
Where ketamine fits
Inpatient lidocaine and subanesthetic ketamine infusions are used in specialized headache centers for refractory chronic migraine. Multi-day infusion protocols are most common in this setting.
What current evidence suggests
Retrospective and small prospective studies support short-term benefit; high-quality randomized trials are limited. Most evidence comes from headache specialty centers.
Frequently asked questions
Is this the same as ketamine for depression?+
The medication is the same, but doses, protocols, and clinical setting differ. Headache protocols are typically multi-day continuous infusions.
Who's a candidate?+
Patients with refractory chronic migraine who have failed multiple preventive classes, evaluated by a headache specialist.
