We report two cases of vasospastic angina associated with anaphylactic reaction caused by nonsteroidal anti-inflammatory drugs (NSAIDs). Both patients exhibited anaphylactic manifestations, such as general rash and urticaria, along with angina pectoris with electrocardiographic ST-segment elevations after suppository administration of diclofenac sodium or indomethacin, the most commonly used NSAIDs. Although these patients had normal coronary arteriograms, intracoronary administration of ergonovine or acetylcholine provoked diffuse coronary artery spasms accompanied by chest pain and ischemic ST-segment changes. It is therefore suggested that an allergic mechanism may be involved as a causative factor of the coronary artery spasm induced by NSAIDs.

Diclofenac sodium is a 2-arylacetic acid, nonsteroidal anti-inflammatory drug. It is widely used in pain management. Side effects such as urticaria, asthmatic attack, vasospastic angina, ischemic stroke, and Kounis syndrome may be seen after the use of diclofenac sodium. However, anaphylactic shock is rare. Anaphylactic shock secondary to injection of diclofenac sodium can be treated successfully with intramuscular injection of adrenaline. Because diclofenac sodium is commonly used in analgesic treatment in emergency departments, we present this case report to emphasize that anaphylactic shock may be seen after the use of that drug.
