What describes Behind-The-Counter (BTC) medications?

Behind-The-Counter (BTC) medications are a specific category of nonprescription medications that, while not requiring a prescription, do necessitate oversight from a pharmacist during the sale. This classification is essential for regulating certain drugs that have the potential for misuse or require monitoring due to their effects or ingredients.

In this case, BTC medications bridge the gap between over-the-counter (OTC) drugs and prescription medications. They are available to consumers but are more strictly controlled, often requiring customers to provide identification or meet other criteria before the drug can be sold. This is particularly relevant for medications that can be abused or that have specific sale restrictions, such as pseudoephedrine, which is commonly used in the manufacture of illicit drugs.

Thus, the correct answer accurately captures this definition, highlighting the unique nature of BTC medications that distinguishes them from both freely available nonprescription medications and those requiring a prescription.
