PedsCalc

PedsCalc is a web-based pediatric dose calculator and clinical-reference toolkit for pediatricians, physicians, nurses, pharmacists, medical students, and caregivers. It brings about 150 pediatric calculators and guides—including 65 medication dose calculators—into one searchable resource for infants, children, and teens. Use PedsCalc for weight-based pediatric dosing and common medication math: mg/kg per dose, mg/kg/day, dose frequency, medication strength, and mg-to-mL conversion. Medication calculators cover acetaminophen (Tylenol), ibuprofen (Motrin/Advil), amoxicillin, Augmentin, cephalexin (Keflex), azithromycin, cefdinir, clindamycin, ondansetron, prednisolone, dexamethasone, oseltamivir, antihistamines, reflux medications, antifungals, antivirals, and other pediatric prescriptions. Pages provide formulas, common product concentrations, practical mL-per-dose conversions, related guidance, references, FAQs, and safety reminders where applicable. The broader pediatric calculator library includes: • Newborn and neonatal tools: AAP 2022 bilirubin, APGAR, New Ballard Score, neonatal hypoglycemia, gestational age, corrected age, feeding, glucose infusion rate, NAS assessments, and preterm growth references. • Growth and anthropometrics: pediatric BMI, BMI percentile, height and weight percentiles, head circumference, body surface area, CDC and WHO growth charts, Fenton and Olsen preterm growth tools, and midparental height prediction. • Fluids, renal, and laboratory math: Holliday-Segar IV maintenance fluids and 4-2-1 hourly rates, infusion and drip-rate conversion, dehydration and oral rehydration, pediatric eGFR by Schwartz, anion gap, corrected sodium, blood volume, and transfusion volume. • Emergency and acute care: pediatric vital signs, shock index, PECARN head injury, Glasgow Coma Scale, pediatric trauma and burn tools, PEWS, appendicitis and Kocher criteria, fever thresholds, and other bedside scores. • Respiratory and cardiology: Westley croup score, pediatric asthma and bronchiolitis assessments, QTc, oxygenation index, and PaO2/FiO2 ratio. • GI and inflammatory disease: PCDAI, PUCAI, PELD, and related pediatric reference calculators. Users can browse by medication or clinical category, search the calculator library, enter the patient-specific inputs required by a tool, review the displayed formula and result, and then compare the output with an authoritative reference or local protocol. The focused web interface is designed to make repeated pediatric calculations easier to find and work through on desktop or mobile browsers. PedsCalc is useful for clinicians checking prescribed weight-based math, nurses reviewing bedside calculations, pharmacists verifying concentration conversions, medical and nursing students learning pediatric formulas, and caregivers who need to understand a clinician-directed plan. Educational guides also explain pediatric dosage calculations, mg/kg conversions, liquid concentrations, dosing charts, clinical scores, and common calculator workflows in plain language. Core PedsCalc calculators are free and ad-supported on the web. An optional PedsCalc Pro subscription adds an ad-free experience, an installable home-screen web app, local notes, and quick history. Important: PedsCalc is a calculation and educational support resource, not a prescriber, diagnosis service, emergency service, or substitute for professional judgment. A calculator result does not determine whether a medicine or treatment is appropriate. Always verify the indication, patient age and weight, exact concentration, dose, route, interval, maximum dose, allergies, interactions, contraindications, renal or hepatic adjustments, current references, and local protocols with a qualified clinician or pharmacist before making a care decision.
