title: Reduction of migraine attacks during the use of warfarin.
abstract: Two recent reports on reduction of migraine attacks during treatment with vitamin K antagonists have caught my attention. Being a migraine sufferer myself, with considerable improvement of my headache during the use of warfarin, I became interested in the subject. Recently, a young man sought my advice for migraine attacks which had worsened after the withdrawal of warfarin. The previous reports on migraine and warfarin involved elderly patients. I report now on these two patients in their 30s, one of them being myself (case 1), who have experienced reduction of migraine attacks during the use of warfarin.
