Abstract

OBJECTIVE: Topiramate is an effective and generally well-tolerated migraine preventive therapy, as shown in three large, randomized, double-blind, placebo-controlled registration trials. Based upon efficacy/tolerability, topiramate 100 mg/day (50 mg BID) is the recommended target dose for most patients with migraine. To further assess the safety and tolerability of topiramate for migraine prevention, we analyzed safety data from 1,580 patients who participated in the three pivotal registration trials or an earlier pilot, randomized, double-blind, placebo-controlled trial.

METHODS: The safety population consisted of all patients who took >or=1 dose of study medication during the double-blind phase (topiramate 50 mg/day [N = 235], 100 mg/day [N = 386], 200 mg/day [N = 514], or placebo [N = 445]). Safety assessments included adverse event (AE) reports, physical examination, and clinical laboratory tests.

RESULTS: Paresthesia was the most common topiramate-associated AE (35%, 51%, and 49% of patients receiving topiramate 50 mg/day, 100 mg/day, or 200 mg/day, respectively [6% on placebo]). The most common topiramate-associated AE were generally mild or moderate in severity and occurred at consistently higher rates during the titration period, compared with the maintenance period of the double-blind phase. AEs leading to withdrawal from the recommended dose of topiramate 100 mg/day included paresthesia (8%), fatigue (5%), nausea (2%), and difficulty with concentration (2%). Serious AEs were infrequent, occurring in 2% of 1,135 topiramate-treated patients and 3% of 445 placebo-treated patients. Patients on topiramate experienced significant decreases in mean body weight compared with placebo.

CONCLUSIONS: Topiramate is generally safe and reasonably well tolerated for the prevention of migraine in adults. The most common topiramate-associated AEs were mild or moderate in severity and occurred more frequently during titration to target doses.
