Two figures in, a clear answer out. The dosage calculator uses dosage, frequency, liquid dose, total liquid dose and your weight to produce medicine concentration, total daily dose and dose, applying the standard relationship for this problem in the order the calculation actually needs it.
What Is the Dosage Calculator?
The dosage calculator gives you an estimate of medicine concentration, total daily dose and dose based on dosage, frequency, liquid dose, total liquid dose and your weight.
It is a quick reference figure rather than a diagnosis, and it is most useful for tracking how a number moves over time rather than for interpreting a single reading.
How the Dosage Estimate Is Worked Out
The calculation follows published reference relationships, so it is a reasonable approximation when the inputs are accurate. It assumes an average adult and does not account for individual variation.
If you are comparing two people, or the same person over a period of weeks, keep the method and the inputs identical. A change in the method can easily look like a change in the person.
What This Calculator Does Not Do
It does not diagnose anything, and it does not replace advice from a clinician. If a figure comes out at an extreme, or if it differs sharply from what you expect, that is a reason to speak to a professional rather than to adjust the inputs.
Nothing you type here is stored or sent anywhere. The whole calculation happens in your browser.
A Worked Example
Working through an example, with dosage set to 10, frequency set to 1, liquid dose set to 5, the calculator returns dose of 1,000, and medicine concentration of 200, and total daily dose of 1,000. Substitute your own figures and the same steps produce the same kind of answer.
Frequently Asked Questions
What do I need to work out medicine concentration?
Enter dosage, frequency, liquid dose, total liquid dose and your weight. The calculator then works through the relationship and reports medicine concentration, total daily dose and dose.
What does the dosage actually calculate?
It takes dosage, frequency, liquid dose, total liquid dose and your weight and converts them into medicine concentration, total daily dose and dose using the standard relationship for this problem. Each step is applied in turn, so every output is traceable back to the numbers you typed in.
How should I enter dosage?
Use the value you actually have, in the unit shown next to the field. Enter every value in the same unit system. The calculator assumes the figures you supply are consistent, so it cannot correct a mistake that happens before the calculation starts.
Is the answer exact?
It is as exact as the formula and the inputs allow. The method itself is the standard one for this problem, so the only sources of error are the figures you enter and the precision you ask for.
Do I have to fill in every field?
Only the fields a particular result depends on. If you leave one blank, the results that need it simply show a note instead of a number, and everything else still works.
