We describe the case report of a migraine sufferer who developed ergotamine-induced headache and subsequently replaced ergotamine with daily sumatriptan (100 mg p.o.). The features of the headache were unchanged except for the presence of superimposed migraine-like headaches that occurred every 24 h.
