Diclofenac induced anaphylaxis: A case report from Nepal.

INTRODUCTION

Diclofenac is considered a generally safe medication, and cause few side effects like dyspepsia, diarrhea/constipation, nausea, and vomiting, stomach bleeding, rash, urticaria, photosensitivity reactions, acute renal failure, analgesic nephropathy, bone marrow and liver diseases. Rarely, it causes anaphylactic reaction.

CASE PRESENTATION: We report a case of 40 years male who developed anaphylactic reaction after intravenous infusion with diclofenac.

DISCUSSION: Both the pulmonary embolism and anaphylaxis guidelines emphasize the importance of a thorough evaluation when making a diagnosis. Mast cells secrete tryptase, a neutral protease that is specifically concentrated in the secretory granules of human mast cells (but not basophils), along with histamine, as a marker of mast cell activation.

CONCLUSION

Although intravenous diclofenac sodium is a safe and often used medicine, it can cause severe and perhaps fatal anaphylactic responses.
