For a 90-day supply of medication, what is the refill timing?

When considering the refill timing for a 90-day supply of medication, it's important to understand how refills work in relation to the quantity of medication prescribed. A standard practice is that refills should occur shortly before the patient runs out of medication, ensuring they maintain consistent therapy without interruption.

A 90-day supply is designed to last for three months. Refills would typically be set to allow the patient to request the next supply when they have approximately 7-10 days of medication remaining. This timing helps prevent gaps in treatment.

The correct answer suggests a refill timing of 80-90 days, aligning with this standard practice. It ensures that by the time the patient reaches the end of this supply, a refill can be initiated. This timing minimizes the risk of running out of the medication before a refill can be obtained.

In contrast, other options propose refill timings that either occur too early or too late in relation to when the medication would be almost depleted, which could compromise the patient's treatment continuity.
