Aceclofenac-Induced Drug Reaction with Eosinophilia and Systemic Symptoms Syndrome

Drug Reaction with Eosinophilia and Systemic Symptoms (DRESS) syndrome is a rare but severe and potentially life-threatening systemic clinical condition. We report a case of a 44-year-old female, who developed DRESS syndrome after taking two doses of aceclofenac, paracetamol, and thiocolchicoside fixed-dose combination. The patient presented with maculopapular rashes, itching, fever, pedal edema, swelling of the face and lips, difficulty in swallowing, loose stools, and vomiting for 4 days following drug intake. Laboratory and histopathological investigations supported the diagnosis following RegiSCAR criteria. The DRESS syndrome in this patient was definite as per Naranjo’s adverse drug reaction probability scale. The patient was adequately managed using systemic corticosteroids, antibiotics, and intravenous fluids. Aceclofenac is the most likely causative agent of DRESS syndrome in this patient. Early detection and withdrawal of the suspected drug along with adequate supportive treatment are the mainstay of management.
