Hemicrania continua (HC) is a primary headache disorder characterized by a continuous, moderate to severe, unilateral headache and defined by its absolute responsiveness to indomethacin. However, some patients with the clinical phenotype of HC do not respond to indomethacin. We reviewed the records of 192 patients with the putative diagnosis of HC and divided them into groups based on their headaches' response to indomethacin. They were compared for age, gender, presence or absence of specific autonomic symptoms, medication overuse, rapidity of headache onset, and whether or not the headaches met criteria for migraine when severe. Forty-three patients had an absolute response and 122 patients did not respond to adequate doses of indomethacin. The two groups did not differ significantly in terms of age, sex, presence of rapid-onset headache, or medication overuse. Autonomic symptoms, based on a questionnaire, did not predict response. Eighteen patients could not complete a trial of indomethacin due to adverse events. Nine patients could not be included in the HC group despite improvement with indomethacin: one patient probably had primary cough headache, another paroxysmal hemicrania; three patients improved but it was uncertain if they were absolutely pain free, and four patients dramatically improved but still had a baseline headache. We found no statistically significant differences between patients who did and did not respond to indomethacin. All patients with continuous, unilateral headache should receive an adequate trial of indomethacin. Most patients with unilateral headache suggestive of HC did not respond to indomethacin.
