Under which premise can a drug be classified as needing a prescription in Ohio?

A drug can be classified as needing a prescription in Ohio when it is labeled as "RX only." This designation indicates that the drug requires a healthcare provider's authorization for dispensation due to factors such as its potential for misuse, the need for professional oversight regarding its use, and the complexities involved with its administration. The "RX only" label typically correlates with the potential risks and benefits assessed by regulatory bodies like the FDA, ensuring that patients have the appropriate medical guidance necessary when using the substance.

The other options presented do not inherently establish the need for a prescription. For example, a drug marketed as a nutritional supplement does not automatically require a prescription, as these products are often available over-the-counter. Homeopathic products may also be sold without a prescription, depending on their classification and the applicable regulations, and drugs marketed without any restrictions would generally not be classified as prescription-only. Hence, the labeling of "RX only" is a clear and direct indicator that a prescription is necessary under Ohio law.
