BACKGROUND: Adverse drug reactions (ADR) in the pediatric emergency room of a tertiary care hospital in Spain are described and compared with the adult ward. METHODS: Identification of cases was carried out through review of admission diagnoses and selection of those included in a previous list of diagnoses considered as possible ADR, that were thereafter verified. RESULTS: During 25 months, in 47.107 pediatric consultations were detected 451 cases as suspicious of ADR (0.96%). The ADR was moderate in 29 and serious in 1, being hospitalized 4. In adults, there were 68,431 consultations, and 704 cases detected (1.03%); moderate 218, serious 34 and mortal 1, being hospitalized 101. The most common reactions were dermatological (43.9% in children, 19.5% in adults) and of digestive nature (28.5 and 36.6%, respectively). The drugs most frequently involved in children were antimicrobials (49.5%), drugs used in respiratory illnesses (19.9%), non-steroid anti-inflammatory drugs (NSAID) (10.4%) and vaccines (9.2%); only two recently marketed products were involved. In adults, drugs involved were NSAID (28.2%), cardiovascular drugs (15.9%), antimicrobials (14.5%) and drugs active in digestive system (11.1%). There were 10 cases of hypoglycemia in diabetic adults, probably by interaction of hypoglycemic agents with angiotensin-converting enzyme inhibitors, and 7 cases of gastrointestinal hemorrhage associated with ketorolac, that generated an alert; 12 recently marketed products were involved. CONCLUSIONS: Intensive monitoring in emergency ward measures ADR problem, estimates underreporting, but it has a moderate value to generate alert or to survey new products.
