Paediatric dose calculator

Weight-based dose with a maximum cap, converted to ml for the syrup strength you prescribe.

For registered doctors only. This is arithmetic, not a prescription. Check the dose, frequency and maximum against a current paediatric formulary and the child's condition, kidney and liver function. Parents: please do not dose medicines with this tool; ask your doctor.

From your formulary for this medicine and indication.

Optional cap; the dose never goes above it.

Like "250 mg/5 ml" or "120mg/5ml".
