Chronic cluster headache remains refractory to medical therapy in at least 30% of those who suffer from this condition. The lack of alternative medical therapies that are as effective as, or more effective than, lithium carbonate makes new therapies necessary for this highly disabling condition. Based on a previous report, we gave oral anticoagulants to three patients with chronic cluster headache. Two of them remained cluster headache-free while taking warfarin. In the third patient, the use of warfarin for three weeks initially increased the frequency and intensity of cluster headache attacks but subsequently induced a prolonged remission. In spite of the paucity of data available, oral anticoagulation appears to be a promising therapy for chronic cluster headache.

Isolated reports of a possible positive effect of anti-coagulant drugs, among them heparin, warfarin and acenocumarol, in migraine prophylaxis are found in the literature. We report the case of a 37 years old man suffering from refractory chronic cluster headache that presented remission with the administration of warfarin for the treatment of deep venous thrombosis associated to arterial thrombosis.
