Augmentin Dose Calculator
for Children
Paediatric amoxicillin/clavulanate dosing for acute otitis media using the current Malaysian National Antimicrobial Guideline.
Amoxicillin / clavulanate
NAG paediatric AOM dosing
Dose is based on the amoxicillin component.
| Formulation ratio | Amoxicillin dose | Frequency | Maximum |
|---|---|---|---|
| 14:1 | 80–90 mg/kg/day | BD | 3 g/day |
| 7:1 | 40–50 mg/kg/day | BD | 3 g/day |
The calculator uses 90 mg/kg/day for 14:1 and 50 mg/kg/day for 7:1 — the upper ends of the exact dose ranges stated by NAG. NAG gives 7–10 days below 2 years and 5–7 days above 2 years; SetelDoc displays 7 days, which falls within both published ranges.

Augmentin paediatric-dose FAQ
What dose does NAG use for 14:1 Augmentin in paediatric AOM?
NAG gives 80–90 mg/kg/day based on the amoxicillin component, orally in 2 divided doses, with a maximum amoxicillin dose of 3 g/day.
What dose does NAG use for 7:1 Augmentin in paediatric AOM?
NAG gives 40–50 mg/kg/day based on the amoxicillin component, orally in 2 divided doses, with a maximum amoxicillin dose of 3 g/day.
Why does SetelDoc calculate 90 mg/kg/day or 50 mg/kg/day?
Those are the upper ends of the respective NAG ranges: 80–90 mg/kg/day for 14:1 and 40–50 mg/kg/day for 7:1. This is a SetelDoc calculator choice and is labelled separately from the full NAG ranges.
How long is treatment for AOM?
Current NAG lists 7–10 days below 2 years and 5–7 days above 2 years. SetelDoc displays 7 days because it falls within both published ranges.
Are 228 mg/5 mL and 457 mg/5 mL the same ratio?
Yes. The current Malaysian NPRA Augmentin product insert states 228 mg/5 mL contains 200 mg amoxicillin + 28.5 mg clavulanate, and 457 mg/5 mL contains 400 mg amoxicillin + 57 mg clavulanate. Both are approximately 7:1.
