Abstract

AIM:

To monitor and evaluate the pattern of ADRs to oseltamivir in pediatric population suffering from H1N1 influenza at a tertiary care hospital.

MATERIALS AND METHODS:

Children offered oseltamivir for treatment and chemoprophylaxis were monitored for adverse events by direct questioning for symptoms and clinical examination on day 5 and day 10. Assessment of neurological events was done by asking the parents or guardians regarding development of specific symptoms. Adverse events obtained were analyzed for severity, causality and age-group wise.

RESULTS:

Out of 191 children (median age, 3 years), 69 (36.1%) developed ADRs. Most common symptoms were vomiting (16.2%) followed by diarrhea (12.0%), ear disorders (8.9%), and insomnia (6.8%). The incidence of neuropsychiatric symptoms was 12.6% which were mild-to-moderate on severity scale. There was no significant difference in the incidence of adverse events between children less than 1 year and other age groups.

CONCLUSION:

Oseltamivir is well tolerated in Indian children with suspected or confirmed H1N1 influenza. Our study also indicates safety of oseltamivir in infants.

KEYWORDS:
