Abstract
Background: Headaches with marked, specific response to indomethacin occur in children, but the phenotypic spectrum of this phenomenon has not been well-studied. Methods: We reviewed pediatric patients with headache showing ≥80% improvement with indomethacin, from seven academic medical centers. Results: We included 32 pediatric patients (16 females). Mean headache onset age was 10.9 y (range 2–16 y). Headache syndromes included hemicrania continua (n = 13), paroxysmal hemicrania (n = 10), primary stabbing headache (n = 2), short-lasting unilateral neuralgiform headache attacks with conjunctival injection and tearing (n = 1), primary exercise headache (n = 1) and primary cough headache (n = 1). Adverse events were reported in 13, most commonly gastrointestinal symptoms, which often improved with co-administration of gastro-protective agents. Conclusion: Indomethacin-responsive headaches occur in children and adolescents, and include headache syndromes, such as primary cough headache, previously thought to present only in adulthood. The incidence of adverse events is high, and patients must be co-treated with a gastroprotective agent.
