Route: Enteral

Formula basis: 90 mg/kg/day divided into 2 doses (per-day)

Maximum single dose: 1,000 mg per dose

Maximum daily dose: 2,000 mg/day

Amoxicillin — Reference Single Dose (q12h (2 divided doses))

Amoxicillin — Reference Schedule Total

Reference arithmetic only — not a prescription or administration instruction. A qualified clinician or pharmacist must verify the patient, indication, product, route, interval, and all applicable limits.

About

This Pediatric Dosing Calculator performs arithmetic for three narrowly defined, cited reference regimens. Each option states its indication or age scope, route, per-dose or per-day basis, interval, and separate single-dose and daily maximums. It is not a prescribing tool and does not determine whether a medicine is appropriate. Confirm the indication, current measured weight, age, formulation, concentration, route, allergies, contraindications, organ function, concurrent medicines, and local pediatric reference before any clinical use.

Formula

Per-dose regimen: Single dose = Weight (kg) × mg/kg/dose
Per-day regimen: Single dose = [Weight (kg) × mg/kg/day] / Number of divided doses
Single-dose and daily maximums are calculated separately; the lower applicable limit is used
