Cytotoxic medications require special handling because they:

While patient counseling is important in the administration of many medications, it is not unique to cytotoxic drugs. Many pharmaceuticals require counseling to inform patients about side effects, interactions, and usage; therefore, this choice does not specifically address the rationale for special handling of cytotoxic medications.

Although some medications may cause visual disturbances as a side effect, this is not a characteristic that necessitates special handling protocols for cytotoxic medications. The handling guidelines are primarily focused on the reproductive and general health hazards posed by these drugs, rather than visual side effects.

While cytotoxic medications may indeed have specific ordering protocols to ensure proper management and safety, this aspect does not directly correlate with the need for special handling procedures. The focus of special handling is more about the health risks associated with exposure rather than the ordering process itself.
