This calculator helps you determine the correct dosage of a medication based on the patient's weight and the prescribed concentration of the drug. It's crucial to double-check all calculations with a healthcare professional before administering any medication.

Understanding Medication Dosing
Accurate medication dosing is paramount in healthcare. The "Dose Calibrator" assists in calculating two critical values:
Total Dose Required: This is the total amount of the active drug the patient needs, typically calculated based on their weight and the prescribed dosage per unit of weight (e.g., milligrams per kilogram or mg/kg). The formula is:
Total Dose Required (mg) = Patient Weight (kg) × Dosage per Kilogram (mg/kg)
Volume to Administer: Once the total dose is known, this calculation determines the actual volume of the medication solution to draw up and administer. This depends on the concentration of the medication, which is usually expressed in milligrams per milliliter (mg/mL). The formula is:
Volume to Administer (mL) = Total Dose Required (mg) / Concentration of Medication (mg/mL)
Example: A doctor prescribes 5 mg/kg of a medication for a patient weighing 70 kg. The available medication concentration is 250 mg/mL.
Calculate Total Dose Required: 70 kg × 5 mg/kg = 350 mg
Calculate Volume to Administer: 350 mg / 250 mg/mL = 1.4 mL
Therefore, you would need to administer 1.4 mL of the medication solution to deliver the correct dose of 350 mg.
