PurposeThe aim of this report is to increase awareness of a possible association between cranial nerve paresis and the use of sumatriptan in migraine sufferers, particularly in patients who have additional vascular risk factors.Patients and methodsWe describe a series of three cases where third nerve paresis developed in patients who were treated with the oral form of sumatriptan. All of the patients had a clear history of repetitive migraine headache and none of them had previous third nerve paresis.ConclusionAmong a variety of medications for the treatment of migraine, there are some drugs with vasoconstrictive effects, particularly triptans. These drugs may be a contributing factor for microvascular damage of the cranial nerves and other organs.
