What is a 28 Day Prescription Refill?

A 28 Day Prescription Refill is a system where a patient’s medication is prescribed to last for 28 days, after which a new prescription is required to continue the medication. This system is designed to ensure that patients take their medication regularly and as prescribed, and it also allows healthcare providers to monitor the patient’s medication usage and make any necessary adjustments to the prescription. It is commonly used for chronic conditions that require ongoing medication.

Example Calculation 1

Let's assume the following value:

Using the formula:

\[ R = \frac{90}{28} \approx 3.21 \approx 4 \text{ refills (round up)} \]

The number of refills needed is 4.

Example Calculation 2

Let's assume the following value:

Using the formula:

\[ R = \frac{150}{28} \approx 5.36 \approx 6 \text{ refills (round up)} \]

The number of refills needed is 6.
