Enter the dosage ordered, concentration, and patient weight to determine the volume to administer.

Dosage Calculation Formula

The following formula is used to calculate the volume to administer from the dosage and concentration.

Volume to Administer = Dosage / Concentration

Variables:

  • Volume to Administer is the amount of medication to administer (mL)
  • Dosage is the prescribed amount of medication (mg)
  • Concentration is the strength of the medication solution (mg/mL)

To calculate the volume to administer, divide the dosage by the concentration.

What is Dosage Calculation?

Dosage calculation refers to the process of determining the correct amount of medication to administer to a patient based on various factors such as the prescribed dosage, the concentration of the medication, and the patient’s weight. Proper dosage calculation is crucial to ensure the effectiveness of the medication while minimizing potential side effects.

How to Calculate Dosage?

The following steps outline how to calculate the dosage using the given formula.


  1. First, determine the prescribed dosage and the concentration of the medication.
  2. Next, determine the patient’s weight if the dosage is weight-based.
  3. Use the formula from above: Volume to Administer = Dosage / Concentration.
  4. Finally, calculate the volume to administer by plugging in the values.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem:

Use the following variables as an example problem to test your knowledge.

Dosage Ordered = 200 mg

Con centration = 50 mg/mL
