Pediatric Dosing Calculator

It performs source-specific milligram arithmetic for three exact reference regimens after the medicine, indication, route, completed age, and current measured kilogram weight have already been established. It does not prescribe a medicine or decide whether any regimen is appropriate.

The page contains only an amoxicillin acute-otitis-media high-dose twice-daily reference for completed ages 6–155 months, an ibuprofen oral-suspension mild-to-moderate-pain label branch for 6–23 months, and the acetaminophen injection 15 mg/kg q6h label branch for 24–155 months.

Those are clinical decisions that require diagnosis, contraindication, allergy, interaction, organ-function, duplicate-ingredient, and local-pathway review. Selecting an option here only identifies the exact cited arithmetic branch; it does not recommend treatment.

Each source branch has a completed-age range and uses weight-based arithmetic. Enter both completed-age fields, including zero, and confirm a current measured kilogram weight. The page does not import the Pediatric Weight estimate, use a parent estimate, or decide whether the weight is plausible or which special dosing-weight method applies.

mg/kg/dose describes one dose calculation. mg/kg/day describes a total or limit across 24 hours. They cannot be interchanged, and an absolute single-dose maximum can constrain the same regimen separately from its 24-hour limit.

After antibiotic treatment and this exact branch have been selected independently, the arithmetic uses 45 mg/kg/dose twice daily, usually no more than 1,000 mg for one dose and no more than the lower of 90 mg/kg/day or 2,000 mg/day. It does not select observation versus antibiotics, an alternative antibiotic, or treatment duration.

For completed ages 6–23 months, the selected label branch uses 10 mg/kg/dose every 6–8 hours, no more than four doses or 40 mg/kg in 24 hours. Because the interval is variable, the page does not invent a fixed planned daily total. It does not screen dehydration, kidney risk, gastrointestinal risk, NSAID hypersensitivity, interactions, or concomitant NSAIDs.

For completed ages 2–12 years, this page calculates only the 15 mg/kg q6h branch, with a 750 mg single-dose maximum and an all-route, all-product maximum of the lower of 75 mg/kg or 3,750 mg in 24 hours. It does not calculate the alternative q4h branch, infusion volume, or detect other acetaminophen exposure.

They represent different constraints. The raw weight-based single-dose arithmetic may be limited by an absolute single-dose maximum. A fixed schedule can then produce a schedule total, while the patient-specific 24-hour limit is calculated independently. A variable interval such as ibuprofen every 6–8 hours has no fixed schedule total.

No. Milliliters depend on the exact dispensed product concentration in mg/mL and an independently verified prescription or protocol. This page does not select a formulation or concentration and does not generate a household or clinical administration volume.

Allergy, contraindications, kidney or liver function, dehydration, gastrointestinal bleeding risk, interactions, duplicate ingredients, obesity, low weight, unusual body composition, special dosing-weight methods, formulation concentration, route, duration, and monitoring can all require independent review. Neonatal and unlisted regimens are not provided.

No. It is source-specific arithmetic only after a clinician has selected an exact medicine, indication, route, and regimen. It does not diagnose, prescribe, say to give or administer a medicine, determine duration, create dosing times, or replace the current label, prescription, pharmacist, or local protocol.
