Which term refers to a medication that can be purchased without a prescription?

The term that refers to a medication that can be purchased without a prescription is OTC drug, which stands for "over-the-counter" drug. OTC medications are available for consumers to buy directly without the need for a healthcare provider's prescription. These drugs are typically considered safe and effective for use by the general public when used as directed on the label.

OTC drugs cover a wide range of products, including those for pain relief, cold and flu symptoms, allergies, and digestive issues. They are manufactured with a lower risk profile, allowing individuals to self-diagnose and treat minor health problems.

In contrast, prescription drugs require a healthcare provider's order because they may have more severe side effects, pose a higher risk for misuse, or need specific monitoring. Generic medications refer to drugs that are chemically identical to their brand-name counterparts but sold under their chemical names. Controlled substances refer to medications that are regulated by law due to their potential for addiction or abuse, and they also require a prescription. Therefore, OTC drug is the accurate choice for medications that don’t require a prescription.
