Drug Dose Calculator

Formula

The formula to calculate the drug dose is:

\[ \text{Dose} = \left( \frac{\text{Desired Amount (D)}}{\text{Amount on Hand (H)}} \right) \times \text{Quantity (Q)} \]

Where:

\( \text{Desired Amount (D)} \) is the dose prescribed.
\( \text{Amount on Hand (H)} \) is the available dose or concentration.
\( \text{Quantity (Q)} \) is the form and amount in which the drug is supplied (e.g., tablet, capsule, liquid).

Example

Let's say the desired amount is 500 mg, the amount on hand is 250 mg per tablet, and the quantity is 1 tablet. Using the formula:

\[ \text{Dose} = \left( \frac{500}{250} \right) \times 1 = 2 \text{ tablets} \]

So, the dose is 2 tablets.
