Allergic reactions, including anaphylactoid shock due to contrast material, are not uncommon. However, persistent anaphylactoid shock refractory to conventional therapy is rare. We present a case of refractory anaphylactoid shock during coronary angiography unresponsive to aggressive standard therapy in a patient on beta‐blockers. Significant clinical improvement was noted upon administration of glucagon. Since beta‐blockers are commonly used in patients with coronary artery disease, this potentially life‐threatening complication has to be kept in mind with any procedure involving contrast media in patients on beta‐blockers. Immediate access to glucagon by keeping it in the procedure room may be lifesaving in these situations. © 1996 Wiley‐Liss, Inc.
