Which category of drugs can be obtained without a prescription?

Nonprescription drugs, also known as over-the-counter (OTC) medications, are the category of drugs that can be obtained without a prescription. These medications are typically considered safe and effective for the general public when used according to the directions on the label. They are formulated to treat minor ailments, such as headaches, colds, or digestive issues, and can be purchased directly from pharmacies, grocery stores, and other retail outlets.

In contrast, prescription drugs require authorization from a licensed healthcare provider due to their potential for misuse, side effects, or interactions that may necessitate professional oversight. Controlled substances are a subset of prescription drugs that are strictly regulated due to their potential for abuse and addiction. Emergency drugs are typically medications used in critical situations, often available only in hospital settings or for specific medical use. Thus, the availability of nonprescription drugs provides accessibility to common health remedies without the need for a healthcare provider's approval.
