Which waste comprises expired, unused, or contaminated medications that require specialized disposal?

• A. Cytotoxic waste
• B. General medical waste
• C. Pharmaceutical waste
• D. Radioactive medical waste

Answer: (C)

Pharmaceutical waste is the category that covers expired, unused, or contaminated medications and requires specialized disposal because these substances can be hazardous to people and the environment if not handled properly. This waste includes drugs and related products that can contaminate water or soil and may pose risks of exposure or abuse if not disposed through proper channels, such as take-back programs or regulated hazardous-w waste streams or incineration, depending on local rules.

Cytotoxic waste is a safety-specific subset that focuses on highly toxic anticancer drugs and materials contaminated with them, not all medications. General medical waste refers to nonhazardous waste from patient care, which doesn’t require the special disposal methods used for pharmaceuticals. Radioactive medical waste involves materials with radioactivity and is governed by radiological controls. So for the broader group of expired, unused, or contaminated medications needing careful disposal, pharmaceutical waste is the appropriate category.
