Mean daily dose, cumulative dose and duration of treatment are described only for intermittent administration.

Doses and duration of treatment are presented as mean (standard deviation), median (interquartile) and 2.5 – 97.5 percentile range (to exclude extreme values).

IV, intravenous; PO, per os; IM, intramuscular; SC, subcutaneous; IN, intranasal.

The total number of patients indicated for each molecule and used to calculate proportions is the total number of patients for whom we had data on dosing regimen.

87 neonates received acetaminophen by rectal route (0.4%) without detailed data on the dose prescribed.
