Abstract

OBJECTIVE To assess the effectiveness of prophylactic headache treatment in children and adolescents. DATA SOURCES PubMed, EMBASE, Cochrane Database of Clinical Trials, and bibliography of retrieved articles through August 11, 2012. STUDY SELECTION Randomized trials of headache treatment among children and adolescents (<18 years old). INTERVENTION Any placebo-controlled trial or comparisons between 2 or more active medications. MAIN OUTCOME MEASURE Number of headaches per month. RESULTS Among 21 included trials, there were 13 placebo-controlled and 10 active comparator trials (2 also included placebo). Twenty trials focused on episodic migraines and 1 on chronic daily headaches. Drugs more effective than placebo for episodic migraines (<15 headaches per month) included topiramate (difference in headaches per month, -0.71; 95% CI, -1.19 to -0.24) and trazodone (-0.60; 95% CI, -1.09 to -0.11). Ineffective drugs included clonidine, flunarizine, pizotifen, propranolol, and valproate. A single trial of fluoxetine for chronic daily headaches found it ineffective. Patients given placebo experienced a significant (P = .03) decline in headaches, from 5.6 (95% CI, 4.52-6.77; Q = 8.14 [Cochran Q is a measure of the heterogeneity of the included studies]) to 2.9 headaches per month (95% CI, 1.66-4.08; Q = 4.72). Among the 10 active comparator trials, flunarizine was more effective than piracetam (difference in headaches per month, -2.20; 95% CI, -3.93 to -0.47) but no better than…
