Anaphylaxis after intramuscular injection of diclofenac sodium

Published:January 06, 2014DOI:https://doi.org/10.1016/j.ajem.2013.12.049
      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.
