2.4 Dosage Recommendations in

Pediatric Patients Lopinavir and ritonavir tablets are not recommended for once daily dosing in pediatric patients younger than 18 years of age. Lopinavir and ritonavir 100/25 mg tablets should be considered only in children who have reliably demonstrated the ability to swallow the intact tablet.

Body surface area (BSA) can be calculated as follows: The lopinavir and ritonavir dose can be calculated based on weight or BSA: Based on Weight: Patient Weight (kg) × Prescribed lopinavir dose (mg/kg) = Administered lopinavir dose (mg) Based on BSA: Patient BSA (m 2 ) × Prescribed lopinavir dose (mg/m 2 ) = Administered lopinavir dose (mg) Tablet Dosage Recommendation in Pediatric Patients Older than 6 Months to Less than 18 Years: Table 5 provides the dosing recommendations for pediatric patients older than 6 months to less than 18 years of age based on body weight or body surface area for lopinavir and ritonavir tablets.
