Biphasic Anaphylactic Reaction to Ketorolac Tromethamine

Abstract

Ketorolac tromethamine is a recent injectable non-steroidal anti-inflammatory drug (NSAID) with analgesic properties approved for short-term pain management. In spite of its increasing use both in adults and children (1-2), relatively few allergic-like reactions have been reported (3–5). Reactions are often severe, and a death occurred following an intramuscular injection of ketorolac (6).
