What is the FAA’s position on migraine headaches?
All forms of vascular headache—migraine, cluster, atypical, acephalgic, etc.—are disqualifying until the headaches are under good control with appropriate medication and the FAA Aeromedical Certification Division has approved the airman for return to flight status. If the symptoms occur less than twice per year and are not likely to interfere with the safe performance of crew duties, the FAA will approve treatment with abortive medications such as Imetrex.
