Abstract Purpose Patterns of prescriptions are markedly influenced by regional disease entities, medical education, culture, economic status, and available pharmaceutical companies. Features of adverse drug reactions (ADRs) may vary in different countries. In this study, we analyzed the causative drugs and clinical manifestations of spontaneously reported ADRs in Korea. Methods Six Korean Regional Pharmacovigilance Centers collected 1418 cases of spontaneously reported adverse drug events (ADEs) by doctors, pharmacists, and nurses, and the clinical features and causative drugs were evaluated. The data were collected from general hospitals (76.5%), primary clinics, and pharmacies (23.5%). Results Based upon the World Health Organization (WHO)‐Uppsala Monitoring Center criteria (certain—13.7%, probable—46.1%, possible—32.1%), 91.9% of the collected events were suspected to be ADRs and 15.8% of patients experienced serious ADRs. The most prevalent causative drugs were antibiotics (31.6%), followed by contrast dyes (14.0%), non‐steroidal anti‐inflammatory drugs (NSAIDs) (11.1%), anti‐psychotics (5.4%), anti‐convulsants (5.2%), cardiovascular agents (4.8%), anti‐neoplastics (4.6%), and opiates and non‐opiate pain killers (3.5%). Among the antibiotics, cephalosporins (8.1%) were the most common, followed by anti‐tuberculosis agents (5.7%), quinolones (4.0%), vancomycin (3.1%), and penicillin (2.8%). The most common side effect was skin manifestations, which were seen in 42% of the patients, followed by neurologic manifestations (14%), gastrointestinal involvements (12.9%), generalized reactions (9.4%), and respiratory involvements (4.5%). Conclusion Antibiotics, contrast dyes, and NSAIDs were the most common causative drugs for ADRs, which reflects the prescription pattern and the prevalence of diseases in Korea. These data may be useful in establishing a Korean pharmacovigilance system. Copyright © 2009 John Wiley & Sons, Ltd.
