Abstract: BACKGROUND:Off-label drug (OLD) use is common in neonates. OBJECTIVE:There is a dearth of information associating the OLD use and the risk of medication errors in critically ill neonates. Hence, the present study was carried out. METHODS:Drug prescriptions in neonates admitted to the intensive care unit of a tertiary care hospital between September 2018 and June 2019 were evaluated. Details on their demographics, reason for admission in intensive care unit, drug-related information and serum creatinine were extracted. United States Food and Drug Administration approved drug labels were compared. World Health Organization (WHO) anatomy, therapeutic and chemical (ATC) classification was used for drug categorization. We assessed the risk of medication errors in the adult population using a validated tool: medication risk score (MERIS). RESULTS:One hundred and seventy-one neonates with 2394 prescriptions were included in this study. Seventy one percent of the neonates in the present study received at least one OLD/unlicensed prescription item. A trend in increased numbers of OLD/unlicensed drug use in more premature and lower birth weight neonates were observed. Medication risk score was significantly higher in neonates receiving OLD/unlicensed drugs compared to those with only labelled drugs. Very and extreme pre-term (along with very low and extremely low birth weight) neonates were at higher risk of medication errors compared to others. Presence of OLD/unlicensed prescribed items is associated with a potentially increased risk of medication errors by an odds ratio of 20.4 compared to labelled drugs. CONCLUSION:Significant proportions of critically ill neonates received at least one OLD/unlicensed drug and such use was associated with potentially increased risk of medication errors.
