Paediatric Weight-Based Dose & Ceiling Gate Calculator
Calculates paediatric single and daily dose (mg) with automatic adult-ceiling safety capping.
⚠️ Educational Calculation & Clinical Safety Safeguard: Never use household teaspoons for paediatric liquids; verify weight in kg (not pounds). Educational calculations do not replace clinician assessment, patient-specific laboratory monitoring, or institutional prescribing protocols.

Step-by-Step Mathematical Derivation & Explanation:
Validated Formula & Conversion Rules
Raw Dose = Weight (kg) × mg/kg/dose; Recommended Dose = min(Raw Dose, Adult Max Single Dose)Worked Clinical Example
18 kg child at 15 mg/kg/dose q6h (4/day): Single Dose = 18 × 15 = 270 mg (below 1000 mg cap); Daily = 1080 mg/day.
Rounding Rules, Assumptions & Source References
- Rounding Rule: Use calibrated oral syringe for volumes < 5 mL.
- Clinical Assumptions & Limitations: Validated only within the stated physiological input boundaries. For paediatric, renal (Cockcroft-Gault), and critical-care infusion calculations, always cross-check against official product labelling and institutional guidelines.
