How long can a patient utilize a prescription for a non-legend drug?

Patients can utilize a prescription for a non-legend drug indefinitely, as over-the-counter (OTC) products are often available without a prescription. Non-legend drugs, also known as over-the-counter medications, can typically be purchased directly from pharmacies and do not require a prescription for purchase by consumers. This means that once a non-legend drug is deemed safe and effective for general public use, there is no regulatory limit on how long a patient can continue to use it without needing to see a healthcare provider for a new prescription.

In contrast, other options suggest specific timeframes that are more applicable to legend drugs (prescription medications) where regulations mandate that prescriptions have a limited validity period or other constraints to ensure appropriate patient monitoring and safety. Therefore, the idea that a non-legend drug could be used indefinitely without the need for re-evaluation or a new prescription aligns with how OTC medications are intended to function in the healthcare system.
