Formula

#
Core Formula
Volume=Desired DoseDose on Hand×Vehicle Volume\text{Volume} = \frac{\text{Desired Dose}}{\text{Dose on Hand}} \times \text{Vehicle Volume}

How it works: Calculates the required volume of a liquid or number of tablets for a specific dose.

Worked Example

Desired: 500mg, On-hand: 250mg per 5mL -> (500/250) * 5 = 10 mL.

Frequently Asked Questions

What is the "Desired Dose"?

The Desired Dose is the amount of medication ordered by the physician (e.g., 500 mg).

What is the "Vehicle"?

The vehicle is the form the medication comes in, such as 5 mL of liquid or 1 tablet.

Can I use different units?

Yes, but ensure the "Desired Dose" and "Dose on Hand" use the same units (e.g., both mg or both mcg) before calculating.
