title: Dipyridamole-induced epistaxis.
abstract: The case history of a patient treated with dipyridamole who developed severe epistaxis, accompanied by alteration of the platelet aggregation tests, is presented. The bleeding did not respond to local therapy and stopped only after discontinuation of the drug and normalization of the platelet aggregation. Hemorrhage, especially in elderly patients, should be considered as a possible complication of dipyridamole administration.
