Definition

Noun: A medication that can be purchased directly by a consumer from a pharmacy or retail store without the requirement of a prescription from a healthcare professional. These drugs are considered safe and effective for use by the general public when the directions on the label are followed.

Usage

This term is used to describe legally available medicines that do not require a doctor's authorization for purchase. It is often abbreviated as OTC drug. - Example: "For a mild headache, an over-the-counter drug like ibuprofen is usually sufficient." - Example: "Pharmacists can advise customers on which over-the-counter drug is most appropriate for their symptoms."

Advanced Usage
