Are triptans effective and safe when taken during the aura phase of migraine?

CLINICAL HISTORY A 28-year-old woman has migraine with visual aura about two times per month. The visual aura lasts about 30 minutes and is followed by a hemicranial throbbing headache, which becomes severe associated with nausea, light, and noise sensitivity with a duration of up to 24 hours. Questions.—Would an oral triptan or sumatriptan administered subcutaneously be more effective if given during the aura than if given when the headache was mild or moderate to severe? Is there any risk of prolongation of the aura or neurologic deficit if a triptan is given during the migraine aura?
