A "legend" drug is typically defined as a medication that requires a prescription from a licensed healthcare provider before it can be dispensed to a patient. This classification arises from the phrase "Caution: Federal law prohibits dispensing without a prescription," which is often found on the labels of such medications. These drugs are usually regulated by laws to ensure that they are used safely and appropriately under medical supervision, as they may have significant potential for side effects, interactions, or abuse.

In contrast, over-the-counter medications can be purchased without a prescription, allowing consumers the freedom to self-medicate for minor health issues. Herbal supplements and homeopathic remedies are also available without a prescription but do not fall under the same stringent regulations as legend drugs, which are subject to specific approval processes and monitoring by health authorities. Therefore, the term "legend" specifically applies to substances that necessitate a prescription, highlighting their importance in veterinary and human medicine for safe and effective treatment.
