Paracetamol Dose Calculator & Pediatric Safety Guide
Giving your child the right dose of paracetamol (acetaminophen) is essential for safely reducing fever and relieving pain. Because children grow at different rates, standard age-based dosing on medicine labels can easily lead to under- or over-dosing.
Use our interactive Paracetamol Dose Calculator below to determine the exact weight-based liquid dosage (in mL and mg) for your child, review safety interval rules, and learn when to consult a healthcare professional.

Fever Care Beyond Medication
Evidence-based home practices to keep your child comfortable during a fever
Lightweight Clothing
Dress your child in a single layer of loose, breathable clothing. Avoid heavy blankets which trap body heat.
Frequent Hydration
Offer small, frequent sips of water, breastmilk, formula, or oral rehydration fluids to prevent dehydration.
Comfortable Environment
Keep the room well-ventilated and pleasantly cool (around 18-20°C / 64-68°F).
Lukewarm Sponging Warning
Never use cold water, ice baths, or alcohol rubs! Use lukewarm water only if your child finds sponging comforting.
Emergency Fever Red Flags
Seek emergency medical care immediately if your child displays any of these warning signs
Core Rules for Safe Dosing
Essential guidelines every parent and caregiver must follow before giving paracetamol
Weight Over Age
Always use your child's current weight, rather than age, if you know it. Weight is a significantly more accurate measure for pediatric dosing.
Time Gap
Wait a minimum of 4 hours between doses (standard recommended interval is 4 to 6 hours).
Daily Limit
Adhere strictly to the maximum number of doses allowed within a 24-hour period (never exceed 4 doses in 24 hours).
Check Concentration
Look closely at the medicine bottle label to match the milligrams (mg) per milliliter (mL) correctly (e.g. 120 mg/5 mL vs 250 mg/5 mL).
Measuring & Giving Medicine Safely
How to accurately measure liquid medicine and prevent accidental overdosing
Use the Right Tool
Use only the oral syringe or dosing cup that came in the product box to ensure 100% measurement accuracy.
Check Label & Expiry
Verify the active ingredient name, mg/mL concentration, and expiration date before every single dose.
Avoid Dual Dosing
Do not give two different medicines containing paracetamol (e.g. multi-symptom cold syrup) at the same time.
Store Safely
Keep all medicines out of reach and sight of children in a locked cupboard or child-safe container.
