What potential health risk is associated with antiviral medications that selectively kill human cells?

The correct answer highlights the fact that antiviral medications designed to selectively target and kill infected human cells can indeed lead to more serious toxicities. When antiviral treatments work by directly damaging infected cells, there is a possibility that they might also affect surrounding healthy cells, leading to unintended adverse effects on the body.

This can manifest in various ways, including damage to organs or systems that the medications were not intended to target. For instance, if a medication affects rapidly dividing cells, it may compromise the health of tissues that are essential for overall bodily function, leading to additional complications and health issues.

Understanding the pharmacodynamics of these medications is crucial because it can help clinicians anticipate and manage potential toxicities. This consideration is essential for ensuring patient safety and efficacy in treatment.

Other options, while they might raise valid concerns in certain contexts, do not directly address the specific health risk associated with antiviral medications targeting human cells as effectively as the choice indicating more serious toxicities.
