title: Anaphylaxis manifested by hypotension alone.
abstract: Three instances of life-threating adverse reations to intravenous contrast media and penicillin have been presented. Hypotension was the major presenting sign, and was prolonged and relieved only by copious dluid therapy. In 1 case the onset of hypotension was delayed for an hour. Urologists should be aware of the variety and proper treatment of drug reactions.
