These rows are examples only. Use the calculator result and verify the actual product label before giving any medicine.
Low single dose = 5 × weight in kg
Target single dose = selected mg/kg × weight in kg
High single dose = 10 × weight in kg
Daily maximum = lesser of 40 × weight in kg or 1,200 mg
Liquid mL = (dose in mg ÷ concentration in mg) × 5
Low single dose = 200 mg
Target single dose = 200 mg or 400 mg, based on the chosen strategy
High single dose = 400 mg
Daily maximum = 1,200 mg
Tablet equivalents = dose in mg ÷ tablet strength in mg
No. It is an educational estimator for common nonprescription-style ranges. It cannot account for diagnosis, dehydration, drug interactions, kidney function, or all local product rules.
Children are commonly dosed by weight because size changes medicine exposure. Weight-based estimates help the calculator scale the dose more appropriately than age alone.
It withholds automatic dosing when important red flags are selected, such as pregnancy after 20 weeks, kidney disease, ulcer history, anticoagulant use, allergy, or age under 6 months.
Not always. Some products should not be split, and many strengths do not match the estimate exactly. Check whether the product is scored and follow the product directions.
Common pediatric estimates usually use 6 to 8 hours between doses, while common adult nonprescription use often uses 4 to 6 hours between doses.
A daily ceiling helps reduce the chance of exceeding common nonprescription-style use. More is not automatically better and may increase bleeding, stomach, or kidney risk.
This page treats pregnancy at 20 weeks or later as a stop flag. Use a clinician or pharmacist instead of an automatic estimate in pregnancy.
No. Chronic pain plans, inflammatory disease treatment, and prescription-strength dosing need clinician review. This calculator is aimed at common short-term estimate scenarios only.
