—Orthostatic hypotension (OH) during diabetic autonomic neuropathy is frequent, treated with difficulty,1 and associated with a high death rate.2 Recently, indomethacin therapy has been proposed, but it is not devoid of side effects and exposes patients who already have a high risk of vascular diseases to clinostatic hypertension and coronary vasocon-striction.3 Metoclopramide dichlorhydrate therapy has been used with success in a case of severe OH after an extensive sympathectomy.4 Therapy with metoclopramide has frequent side effects, however.5 Domperidone, which antagonizes dopaminergic transmission, does not cross the blood-brain barrier6 and, theoretically, would be more easily tolerated. Therefore, we decided to treat a patient with diabetic OH by domperidone therapy.
