Rectal bleeding induced by Dipyridamole.
Nineteen patients treated continuously with Dipyridamole were evaluated for rectal bleeding. Thirteen suffered from overt rectal bleeding and six served as controls. Hemorrhoids were found in all patients. Contact bleeding was found in 16. The bleeding continued despite rubber band ligation, and stopped only on withdrawal of the drug.
