Most children with pain are managed by either acetaminophen or ibuprofen. However, no study has so far investigated if children are prescribed adequate doses of acetaminophen or ibuprofen in emergency department. Aim of this retrospective study was to investigate the prevalence of under-dosage of these drugs in children presenting with pain in emergency department. Children initially prescribed with acetaminophen or ibuprofen for pain management were included. The χ 2 automatic interaction detection method was used considering the percentage variation from the minimum of the appropriate dose as dependent variable while prescribed drug, age, gender, body weight, type of hospital (pediatric or general), and availability of internal guidelines on pediatric pain management in the emergency department as independent variables. Data on 1471 children managed for pain were available. Under-dosage was prescribed in 893 subjects (61%), of whom 577 were prescribed acetaminophen and 316 ibuprofen. The use of acetaminophen suppositories, body weight <12 kg or >40 kg, and the use of oral ibuprofen identified clusters of children associated with under-dosage prescription.
Conclusion: Prescription of acetaminophen and ibuprofen was frequently under-dosed. The use of suppositories, lower and higher body weight, and the use of ibuprofen were associated with under-dosage. Under-dosing may reflect prescription of anti-pyretic doses.

What is Known:
• Pain is frequent in children presented to emergency department.
• International recommendations on pain management are often not implemented.
What is New:
• Acetaminophen and ibuprofen were frequently underdosed in children prescribed for pain in the Italian emergency departments.
• Under-dosage may be related to the habit of using acetaminophen and ibuprofen in the recommended range for fever treatment.
