What is a Prescription Refill?

A prescription refill is a continuation of a medication that a doctor has previously prescribed, allowing the patient to continue taking the medication without having to visit the doctor again. It is typically authorized for a certain number of refills, indicated on the prescription label, and can be obtained from a pharmacy once the initial supply has been used up. The pharmacist will only refill the prescription if the doctor has approved it and it is not expired.

Example Calculation 1

Let's assume the following values:

Use the formula:

\[ R = \frac{2 \times 30}{20} = \frac{60}{20} = 3 \]

The number of refills needed is 3.

Example Calculation 2

Let's assume the following values:

Use the formula:

\[ R = \frac{1 \times 90}{30} = \frac{90}{30} = 3 \]

The number of refills needed is 3.
