MediHelp feature
Drug dosing reference with the source next to every dose
Find the label dose by indication, age and kidney function, and calculate a mg/kg dose with every step and its source shown.
Short answer
MediHelp's Dosing Reference shows the label dose by indication, age and kidney function, with the source beside it. The Dosing Calculator turns a mg/kg label dose into a volume and shows the formula, your inputs, the arithmetic and the source. Both show label information and do not replace the prescriber's judgement.
What it does
- Dose by indication, age and kidney function. Adult, paediatric, elderly and renal dosing from the label.
- A calculator that shows its work. Formula, your inputs, the arithmetic and the source on one screen.
- Sources on screen. A compact Sources panel sits next to the clinical data.
- Free clinical calculators. Creatinine clearance, eGFR, body size, Child-Pugh, corrected calcium and anion gap, each with its formula and citations.
How to use it
- Pick the medicine and the indication. Choose the patient group, such as age or kidney function.
- Read the label dose and the source. Check the band, the interval and any limits.
- Calculate if the dose is in mg/kg. Enter the weight and read every step of the arithmetic.
Example
- You enter
- Amoxicillin, creatinine clearance 20 mL/min
- You see
- 250-500 mg every 12 hours; every 24 hours below 10 mL/min. Do not use the 875 mg tablet when clearance is below 30 mL/min (FDA label).

Where the information comes from
Doses are label information from official product information such as FDA and EMA labels, shown with the source. Where a label and your local protocol differ, follow the prescriber and your local protocol.
Frequently asked questions
Where do the doses come from?
From the product label, for example FDA and EMA labels, with the source shown next to the dose.
Does it adjust for kidney function?
It shows the label's renal dosing bands. The free creatinine clearance and eGFR calculators help you estimate kidney function.
Does the calculator show how it got the answer?
Yes. It shows the formula, your inputs, the arithmetic and the source.
Can I rely on it for a prescription?
It is a reference. The prescriber and the pharmacist remain responsible for the final dose, checked against the label and local guidance.
MediHelp is a reference and education tool for healthcare professionals and students. It supports, and does not replace, clinical judgement or the official product label. Check anything that affects a patient against the source.
