Which of the following symptoms might indicate a serious adverse reaction from antiviral use?

Sepsis is a serious medical condition that results from the body's extreme response to an infection. It can occur when the immune system overreacts to infection, leading to widespread inflammation and potentially resulting in organ failure or death. When evaluating symptoms of severe adverse reactions to antiviral medications, the presence of sepsis is significant because it represents a life-threatening condition that requires immediate medical attention. In the context of antiviral use, if a patient develops signs of sepsis, such as fever, hypotension, increased heart rate, or confusion, it suggests a serious reaction that warrants further investigation and prompt intervention.

In contrast, fatigue, mild headache, and dry skin are generally not associated with severe adverse reactions. These symptoms can occur for a variety of reasons and are often mild or manageable side effects rather than indicators of a serious medical condition. Recognizing and understanding the implications of sepsis as a potential adverse reaction emphasizes the importance of monitoring patients closely for severe symptoms when they are undergoing antiviral therapy.
