Which of the following medications can be refilled without a prescriber’s authorization?

Over-the-counter medications can be refilled without a prescriber’s authorization because they do not require a prescription for dispensing. These medications are considered safe and effective for self-medication, and individuals can purchase them as needed without the involvement of a healthcare provider.

In contrast, Schedule II medications are strictly regulated and cannot be refilled at all; new prescriptions are required each time. Schedule III medications may be refilled, but only with the prescriber’s authorization and within the limits set by state and federal law. Similarly, controlled substances that have no refills also necessitate a new prescription from a healthcare provider to be dispensed again. Therefore, the only category in which refills can occur without prescriber input is for over-the-counter medications.
