Pediatric Dosage Calculator & Essential Formulary
Evidence-based milligram and milliliter pediatric dosing calibrated to the Indian Academy of Pediatrics (IAP) List of Essential Medicines for Children and India's National List of Essential Medicines (NLEM 2022).
First-line antipyretic & analgesic for fever and mild-to-moderate pain across all ages.
The IAP List of Essential Medicines for Children strictly includes only Paracetamol and Ibuprofen as essential non-opioid antipyretics:
- Never Give Aspirin: Aspirin in children with viral infections carries a known risk of Reye’s syndrome (fatal brain swelling and liver failure).
- Mefenamic Acid Caution: Although present in adult lists, pediatric guidelines avoid routine Mefenamic acid due to a narrow safety margin and seizure/toxicity risks in overdose.
- Nimesulide Banned: Banned by the Government of India for pediatric use under 12 years due to acute hepatotoxicity.
Enter Child's Weight
Pediatric medicine cannot be accurately dosed by age alone. Enter your child's weight above to generate precise milligram and milliliter measurements conforming to national guidelines.

Clinical Dosing Protocols & Evidence-Based Methodology
Curated by Dr. Zahoor Hussain Daraz (MBBS, MD Paediatrics, SCHP Sydney, PGPN Boston, Master's Paediatric Emergency Apollo)
In pediatric medicine, child weight in kilograms is the single most critical determinant of therapeutic efficacy and safety. Age-based approximations on medication boxes are generalized estimates and frequently lead to sub-therapeutic underdosing (prolonging febrile discomfort) or dangerous accidental overdosing.
Target dose is 15 mg/kg per dose (therapeutic threshold 10–15 mg/kg). Minimum dosing gap is 4 hours; max 4 doses in 24 hours. Daily maximum ceiling is 60 mg/kg/day or 4,000 mg.
Target dose is 10 mg/kg per dose(therapeutic threshold 5–10 mg/kg). Minimum dosing gap is 6–8 hours; max 3 doses in 24 hours. Contraindicated under 3 months or < 5 kg.
Frequently Asked Questions: Child Fever & Pain Medications
❓ How do I calculate the correct Paracetamol (Calpol / Crocin) dose for my child?
Pediatric paracetamol must always be calculated by weight (kg) rather than age. The clinical standard is 15 mg per kilogram of body weight per single dose (within a safe range of 10–15 mg/kg), given every 4 to 6 hours as needed. Never exceed 4 doses (or 60 mg/kg) in any 24-hour period.
❓ Why does the Indian Academy of Pediatrics (IAP) only include Paracetamol and Ibuprofen as essential pain/fever medicines?
According to the IAP List of Essential Medicines for Children, Paracetamol and Ibuprofen adequately treat over 95% of childhood fever and inflammatory pain with the highest proven safety margins. Other NSAIDs like Aspirin are avoided due to fatal Reye’s syndrome risk, Nimesulide is banned under 12 years for hepatotoxicity, and Mefenamic Acid has a narrower therapeutic index with seizure risks in accidental overdose.
❓ What is the difference between Paracetamol 120 mg/5 mL, 125 mg/5 mL, and 250 mg/5 mL?
In India, standard pediatric syrups contain either 120 mg or 125 mg per 5 mL (approximately 24–25 mg/mL), which are ideal for babies and toddlers. Forte or DS (Double Strength) formulations contain 250 mg per 5 mL (50 mg/mL), allowing older or heavier children (>15 kg) to take smaller liquid volumes. Always check your bottle label before measuring.
❓ Why is Aspirin strictly prohibited for children and teenagers with viral fevers?
Aspirin (acetylsalicylic acid) given to children during viral infections (such as flu, chickenpox, or colds) can trigger Reye’s syndrome—a rare but often fatal disorder characterized by acute brain edema and fatty liver failure. Paracetamol is the safe antipyretic of choice.
❓ Can I give Paracetamol and Ibuprofen together to reduce fever faster?
Do not routinely combine or alternate paracetamol and ibuprofen without explicit instruction from your pediatrician. Alternating increases the risk of dosing confusion and accidental overdose. Paracetamol is the preferred first-line antipyretic. If fever remains high, consult Dr. Zahoor before adding ibuprofen.
❓ What is the WHO and IAP recommended treatment for acute childhood diarrhea?
The cornerstone protocol consists of WHO Low-Osmolarity ORS (245 mOsm/L) given in frequent sips to replace fluid loss (approx. 10 mL/kg after every loose stool) PLUS Zinc Sulphate dispersible tablets (10 mg daily for infants <6 months; 20 mg daily for children ≥6 months) for 14 continuous days to rebuild gut mucosa and prevent recurrence.
❓ Is Ibuprofen safe for infants under 3 months?
No. Ibuprofen is strictly contraindicated for infants younger than 3 months or weighing under 5 kg. For infants between 3 and 6 months, ibuprofen should only be given under direct pediatric supervision. Always ensure the infant is well-hydrated before giving ibuprofen.
❓ Why is using a domestic kitchen spoon dangerous for child medicine?
Kitchen teaspoons vary drastically in size (ranging anywhere from 2.5 mL to 8 mL). Using kitchen spoons is one of the leading causes of pediatric accidental poisoning and underdosing. Always use a calibrated oral syringe or medicine dropper supplied with the medicine.
❓ What should I do if my baby vomits after taking fever medicine?
If the child vomits immediately (within 10 minutes) and the entire liquid dose is visible, you may repeat the dose once. However, if more than 15–20 minutes have passed, significant absorption has likely occurred—do not repeat the dose; wait for the next scheduled interval (4–6 hours) to prevent toxicity.
❓ When does a fever in a child require immediate emergency pediatric care?
Seek emergency pediatric evaluation immediately if: the baby is under 3 months with a temperature of 38°C (100.4°F) or higher; the child has difficulty breathing or chest indrawing; shows extreme lethargy or unresponsiveness; develops a non-blanching purple rash; or has a convulsion/seizure.
