What is a characteristic of drugs considered hazardous?

Drugs considered hazardous are identified based on specific criteria set forth by organizations such as NIOSH (National Institute for Occupational Safety and Health). These criteria encompass a variety of factors, including the drug's potential for causing adverse effects in healthcare workers, patients, and the environment. These drugs can pose significant risks during handling or administration if appropriate precautions are not taken. Hazardous drugs are defined not solely by their dosage forms or temperature requirements, but rather by their pharmacological effects and the potential for toxicity.

The classification of hazardous drugs is not limited to injectable forms, nor is it dependent on whether they need to be stored at room temperature. Additionally, the classification as a hazardous drug does not inherently correspond to it being a controlled substance; many hazardous drugs are not scheduled controlled substances. Therefore, the correct answer highlights the importance of safety standards established by recognized authorities in identifying and managing hazardous drugs.
