Clinical Details

Official title: An Open-label Observational Safety Study During Administration of Topiramate, for the Prophylaxis of Migraine

Study design: Time Perspective: Prospective

Primary outcome: The primary outcome is effectiveness of topiramate based on the frequency of migraine headaches during the monotherapy with topiramate.

Secondary outcome: Safety of topiramate (number of SAEs, AEs, Laboratory findings)

Detailed description: Previous studies have shown that topiramate is effective in preventing migraine headaches. This is a 6-month observational study to evaluate additional safety data of topiramate in the prevention of migraine in adult patients. The study duration is 6-months, with 5 study visits during the study.
