Enter the weight, age, and select the medication to calculate the correct dosage using the Carithers Dosage Calculator.

## Dosage Calculation Formula

The following formula is used to calculate the correct dosage based on weight and age.

Dosage (mg) = (Weight (kg) + Age (years)) * Dosage Factor

Variables:

- Weight is the body weight of the patient (kg)
- Age is the age of the patient (years)
- Dosage Factor is a constant that varies depending on the medication

To calculate the dosage, add the weight and age, then multiply by the dosage factor specific to the medication.

## What is Dosage Calculation?

Dosage calculation is a crucial process in medicine to ensure that patients receive the correct amount of medication. It involves considering the patient’s weight, age, and the specific medication’s requirements. Proper dosage calculation helps in maximizing the therapeutic effects while minimizing potential side effects.

## How to Calculate Dosage?

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

- First, determine the patient’s weight in kilograms and age in years.
- Next, identify the specific medication and its corresponding dosage factor.
- Use the formula from above: Dosage (mg) = (Weight (kg) + Age (years)) * Dosage Factor.
- Finally, calculate the dosage by plugging in the values.
- 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.

Weight = 70 kg

Age = 30 years

Dosage Factor = 0.1
