Introduction

Prophylactic treatment of migraine is treatment designed to decrease the frequency and severity of migraine attacks. A wide variety of pharmacological and non-pharmacological therapies are available and the choice of drug should depend upon individual situation and other co-existing medical problems. Pharmacological agents are taken on daily basis for weeks or months; occasionally shorter courses are sufficient. Patients should be given an adequate trial of prophylactic agents for at least two months, before it can be deemed a failure.
