💊 Baby Medicine Dose Calculator

Calculate the correct paracetamol and ibuprofen dose for your child — by weight, not by age

Quick Answer

The standard paracetamol dose for babies is 15 mg per kg of body weight, given every 4–6 hours (maximum 4 doses in 24 hours). Never give ibuprofen to babies under 6 months. Never give aspirin to any child. Always weigh your baby before calculating the dose — never estimate by age alone.

⚕️

Always consult your doctor first. This calculator is a reference guide based on IAP/WHO guidelines. Never exceed recommended doses. Paracetamol overdose can cause serious liver damage. Ibuprofen is not for babies under 6 months.

✅ Dosing Safety Rules

Dose by Weight, Not Age

Children of the same age can vary significantly in weight. Always use current weight for accurate dosing.

Minimum 4–6 Hours Apart

Paracetamol: minimum 4 hours between doses. Ibuprofen: minimum 6 hours between doses.

🚫
Never Double-Dose

If you're unsure whether you gave the medicine, do not give another dose. Keep a written log with times.

🚫
No Ibuprofen Under 6 Months

Ibuprofen is not recommended for babies under 6 months or children with kidney problems, dehydration, or stomach issues.

🚫
Never Give Aspirin to Children

Aspirin is linked to Reye's syndrome in children — a rare but serious condition. Never give aspirin to anyone under 18.

Use the Correct Syringe

Always use the dosing syringe or spoon included in the medicine pack. Kitchen spoons are not accurate.

👩‍⚕️ What Paediatricians Say About Medicine Dosing

The Indian Academy of Pediatrics (IAP) recommends weight-based dosing for all children's medicines — not age-based — because Indian children vary widely in size.

  • Always use paediatric drops or syrup — never crush adult tablets for children
  • Indian brand names: Calpol / Metacin = paracetamol; Brufen / Ibugesic = ibuprofen
  • Ibuprofen is not recommended for babies under 6 months or when a child is dehydrated
  • Store all medicines out of children's reach; check expiry dates before every use
