What is the formula to calculate dosage based on weight in mg/kg?

The correct formula to calculate dosage based on weight in mg/kg is to multiply the weight in kilograms by the dosage in mg/kg. This approach provides a clear and practical means to determine the total medication dose required for a patient based on their body weight.

For instance, if a medication is prescribed at a dosage of 5 mg/kg and the patient weighs 70 kg, you would calculate the total dosage by multiplying 70 kg by 5 mg/kg, resulting in a total dosage of 350 mg. This method ensures that dosing is tailored to individual patient needs, promoting both safety and efficacy in medication administration.

Other formulas listed do not align with the standard practice for calculating dosages based on weight. For example, dividing weight by dosage or adding weight to dosage does not yield a relevant or useful figure for medication dosage. Understanding this correct formula is critical for ensuring accurate and effective patient care in a clinical setting.
