Migraine Prophylaxis With Topiramate and Bone Health in Women

Abstract

Antiepileptic drugs (AEDs) are commonly used for prevention of migraine headaches. Bone loss is a known complication, particularly associated with use of older AEDs. Topiramate is a newer AED, widely used for migraine prevention, but no evidence is currently available on its effect on bone metabolism. In a clinic-based pilot study, we evaluated bone health by examining biochemical and radiological markers of bone metabolism, in women with migraine. Osteopenia was noted in 53% of the patients and was associated with the duration of exposure to topiramate (P = .04).
