Benserazide induces migraine attacks. Irrelevance of concomitant hyperprolactinemia

Migrainous women underwent acute administration of sulpiride (25 mg i.v.) and benserazide (125 mg per os), both drugs increasing prolactin secretion. A similar increase in prolactin levels was found following the administration of the two drugs. A typical migraine attack was observed only in the 4 women given benserazide. These data, though being preliminary, stress the scarce or irrelevant role of prolactin in the pathogenesis of the migraine attack.
