Adverse reactions to antibiotics in hospitalized Iranian children.
OBJECTIVE
The aim of this study was to determine the frequency of adverse reactions to antibiotics by organ system in hospitalized children in the infectious ward of a pediatric diseases referral center in Iran.


METHODS
All patients treated with antibiotics were evaluated daily for the presence of ADRs during a 5-month period. For each suspected ADR, a specialized questionnaire was completed in order to obtain the information necessary for analysis of ADRs.


RESULTS
Among 300 patients, 65 ADRs were seen in 36 patients (12%) during their hospitalization. Pneumonia was the most common reason for administering antibiotics; ceftriaxone and rifampin were the most frequently implicated antibiotics in ADRs. There was a significant relationship between the number of drugs used and the rate of ADRs (p=0.0001). The most commonly affected organ systems were skin and appendages, and the gastrointestinal system. Maculopapular rashes were the most frequent skin ADRs.


CONCLUSIONS
As antibiotics are the most frequently used drugs in children, and also because of significant relationship between the number of drugs used and ADRs, limited use and careful selection of type and dose of antibiotics as well as close clinical observation are very important in minimizing ADRs.
