PedsCalc

PedsCalc is a web-based pediatric calculator and medication-reference library for pediatricians, physicians, nurses, pharmacists, medical students, and caregivers. It organizes about 150 child-health tools—including about 65 pediatric medication dose calculators—into one searchable resource for infants, children, and adolescents.

Use PedsCalc for common weight-based medication math such as mg/kg per dose, mg/kg/day, dose frequency, product strength, and mg-to-mL conversion. The medication library includes calculators for commonly referenced pediatric medicines such as acetaminophen, ibuprofen, amoxicillin, Augmentin, cephalexin, azithromycin, cefdinir, clindamycin, ondansetron, prednisolone, dexamethasone, oseltamivir, antihistamines, reflux medicines, antifungals, antivirals, and other pediatric prescriptions. Individual pages may include formulas, common product concentrations, practical liquid-dose conversions, related guidance, references, FAQs, and safety reminders.

The broader pediatric clinical-calculator collection includes growth and anthropometric tools, newborn and neonatal calculators, maintenance-fluid and nutrition calculations, laboratory conversions, emergency and acute-care scores, respiratory tools, cardiology calculations, and gastrointestinal or inflammatory-disease calculators. Users can browse by medication or clinical category, search the library, enter the patient-specific inputs requested by a tool, review the displayed formula and result, and compare the output with an authoritative reference or local protocol.

PedsCalc is useful for clinicians checking prescribed weight-based math, nurses reviewing bedside calculations, pharmacists verifying medication-strength conversions, students learning pediatric formulas, and caregivers seeking to understand a clinician-directed plan. Plain-language guides cover pediatric dosage calculations, mg/kg conversions, liquid concentrations, growth charts, clinical scores, and common calculator workflows.

Many calculators are free and ad-supported in a modern web browser. Optional PedsCalc Pro adds an ad-free installable progressive web app with faster search, locally saved recent calculations, and local notes.

PedsCalc is an educational calculation and reference resource. It is not a prescriber, diagnostic service, emergency service, or substitute for professional judgment. A calculator result does not determine whether a medication 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 labeling and references, local protocols, and other patient-specific factors with an appropriate clinician or pharmacist. In an emergency, use local emergency services and established clinical protocols.
