How to Calculate Paracetamol Dosage for Baby

Calculating the correct paracetamol dosage for babies is crucial for their safety. This guide explains the proper method, provides a dosage calculator, and includes important safety information.

Introduction

Paracetamol (acetaminophen) is a common pain and fever medication, but its dosage for babies must be calculated carefully due to their smaller size and developing organs. The standard dosage for adults is 500mg every 4-6 hours, but babies require a much lower dose.

Always consult with a pediatrician or healthcare professional before administering any medication to a baby. This guide provides a method to calculate the appropriate dosage based on the baby's weight.

Dosage Formula

The standard formula for calculating paracetamol dosage for babies is:

Dosage (mg) = Baby's Weight (kg) × 15 mg/kg

This formula provides a starting point, but the actual dosage may vary based on the baby's condition and the healthcare provider's recommendation.

The maximum recommended dose for babies under 3 months is 15mg/kg, and for babies 3-12 months is 10-15mg/kg. For babies over 12 months, the adult dosage may be considered.

Step-by-Step Calculation

Determine the baby's weight in kilograms.
Multiply the baby's weight by 15 to get the recommended dosage in milligrams.
Divide the total dosage by the number of doses per day (typically 2-3 doses).
Administer the calculated dose at regular intervals.

Important: Never exceed the maximum recommended dosage. Always follow your pediatrician's instructions and never give paracetamol to a baby under 3 months without medical supervision.

Worked Examples

Example 1: Baby weighing 5 kg

Dosage = 5 kg × 15 mg/kg = 75 mg total

If giving 2 doses per day: 75 mg ÷ 2 = 37.5 mg per dose

Example 2: Baby weighing 8 kg

Dosage = 8 kg × 15 mg/kg = 120 mg total

If giving 3 doses per day: 120 mg ÷ 3 = 40 mg per dose

Example 3: Baby weighing 12 kg

Dosage = 12 kg × 15 mg/kg = 180 mg total

If giving 2 doses per day: 180 mg ÷ 2 = 90 mg per dose
