Pharmacy & Dosing Suite
Evaluate precise IV infusion drip rates, convert solution concentrations, approximate pediatric weight adjustments, model pharmacokinetic half-life accumulation, and analyze tablet split savings.
Pediatric Dosing Calculator
Estimate pediatric dosages from adult recommendations using standard pediatric clinical rules: Clark's, Young's, Webster's, Fried's, and BSA methods.
Clark's Rule
Based on Weight (Lbs)Most common general historical rule for children above 1 year.
BSA Method
Clinical Gold StandardHighly reliable; correlates best with cardiac output and metabolic rate.
Young's Rule
Based on Age (1-12 yrs)Not appropriate for infants under 1 year of age.
Webster's Rule
Based on Modified AgeModified Young's formula giving slightly safer dosage margins.
Fried's Rule
Infants < 2 yrs (Months)Standard rule specifically designed for newborn infants and toddlers.
Critical Clinical Pediatric Safety Directive
These mathematical guidelines (Clark's, Young's, etc.) are historical clinical approximations. Pediatric physiology differs fundamentally from adults in renal clearance, hepatic metabolism, and body composition.
Always use drug-specific pediatric dosing standards (e.g. mg/kg per day or mg/kg per dose) verified in official pharmaceutical compendiums (like Lexicomp or Micromedex). Never split adult extended-release or highly concentrated doses for pediatric patients without consulting a pediatrician or clinical pharmacist.
