Which of the following is a common NIOSH hazard drug?

• A. Warfarin
• B. Amoxicillin
• C. Lisinopril
• D. Ibuprofen

Answer: (A)

Warfarin is listed as a hazardous drug by NIOSH because it has reproductive and toxicological risks that matter for workers who handle it. It’s a vitamin K antagonist with well-known teratogenic effects, and exposure to the drug can pose health hazards through skin contact, inhalation, or accidental ingestion during compounding, dispensing, or administration. Because of these potential risks, facilities treat warfarin as a hazardous drug and implement safer-handling practices, such as using protective equipment, engineering controls, spill management, and proper waste disposal to minimize worker exposure.

The other medications listed do not carry the same NIOSH hazardous-drug designation in the occupational-safety sense. Amoxicillin, lisinopril, and ibuprofen are common medications without the specific hazardous-drug classification used for protecting workers during handling.
