What is a prescription?

A prescription is defined as an order for medication or treatment given by an authorized health care professional. This includes directives for specific medications, dosage, frequency, and duration that a patient needs to follow to receive appropriate care. The health care professional who issues the prescription, such as a physician or nurse practitioner, has the legal authority and training to determine what treatment is necessary based on the patient's medical condition.

The other options do not align with the formal definition of a prescription. Over-the-counter medications are available without a prescription and do not require an order from a health care professional. An informal recommendation from a pharmacist lacks the official authority needed for a prescription and does not include specific dosages or instructions. Lastly, a verbal agreement between a patient and a doctor does not equate to a prescription, as it lacks the documentation and specific instructions that are critical for safely administering medications or treatments.
