The premonitory phase of migraine and migraine management

Abstract

Objective: The objective was to determine, through a literature review, whether treatment during the premonitory phase of migraine is a potentially useful migraine management strategy. Methods: A general literature review was done with regard to the nature of migraine premonitory symptoms, their frequency, their reliability in predicting migraine attacks, and the effectiveness of medication treatment when given during the premonitory phase. Results: Many different symptoms have been reported as premonitory symptoms that occur before migraine attacks. Up to 87% of patients with migraine may experience premonitory symptoms, although some studies have provided estimates as low as 33%. In selected patients, premonitory symptoms may be relatively reliable predictors of a migraine attack to follow. Both naratriptan (open-label study) and domperidone (double-blind, randomized, placebo-controlled study) have been reported to be effective when given during the premonitory phase. Conclusions: More research is needed, but there is some evidence that medication treatment during the premonitory phase has the potential to be helpful in selected patients with migraine.
