BACKGROUND: Cutaneous adverse drug reactions (CADRs) are drug-induced skin reactions with or without systemic involvement, ranging from mild maculopapular exanthema (MPE) to life-threatening severe CADRs (S-CADRs). Due to their unpredictability and severity, early recognition of suspected causative drugs is highly recommended. However, the profile of CADRs remains unknown in China. OBJECTIVES: To assess the clinical profile, predominant causative drugs, and cost associated with CADRs in Shanghai, China. MATERIALS AND METHODS: Clinical records of inpatients admitted with a diagnosis of CADRs to the dermatology ward of Huashan Hospital from January 2007 to December 2016 were retrospectively studied. RESULTS: A total of 1,883 patients (1,231 female and 652 male), admitted with a diagnosis of CADR, were investigated. S-CADRs made up 21.99% of all cases (n=414), and urticaria (27.19%) was the most frequent reaction. Of the patients, 53.43% suffered from multiple drug-induced drug eruptions and the rest (45.83%) from single drug-induced drug eruptions. Overall, antimicrobials (28.85%) was the main drug group involved, and for S-CADRs, this was antiepileptic drugs (36.15%). The total cost for CADRs was RMB23,718,788.83 ($3,588,319.04). Both age and sex were related to admission cost (p=0.005 and p=7.84E-8, respectively). Antimicrobials were the most common treatment causing CADRs. CONCLUSION: The management of CADRs requires considerable medical cost. CADRs are not only a health problem but also a significant financial burden for affected individuals.
