Pediatric Ibuprofen (Advil/Motrin) Dosage Calculator
Calculate exact Ibuprofen dosages for children. Supports various concentrations including drops, suspensions, and chewables to prevent dosing errors.
About
Ibuprofen is a common fever reducer and pain reliever for children, but it comes in highly varying concentrations. A critical error parents make is confusing "Infant Drops" (highly concentrated) with "Children's Suspension" (less concentrated), leading to potential overdose. This calculator standardizes the process by requiring the user to select the specific product type found on their bottle.
It covers major formulations found in Western markets, including Infant Drops (50mg/1.25ml), Standard Suspension (100mg/5ml), and Chewables. The logic applies the clinical standard of 10 mg/kg for high fever or pain, ensuring the volume matches the child's exact weight rather than a broad age range.
Formulas
Ibuprofen dosing is strictly weight-dependent. The calculator determines the total milligrams required and maps it to the volume of the selected concentration.
Standard Dose Formula:
Vml = Weight × 10 mg/kgConcentration mg/ml
Maximum daily dose should not exceed 40 mg/kg.
