Which of the following is a major side effect of MAO inhibitors that requires immediate reporting?

1. Fatigue

2. Dry mouth

3. Severe headaches

4. Hallucinations

The correct answer is: Severe headaches

Severe headaches are a significant side effect of MAO inhibitors that necessitate immediate reporting because they can indicate a potentially dangerous condition known as hypertensive crisis. MAO inhibitors work by preventing the breakdown of certain neurotransmitters and compounds, which can lead to elevated levels of tyramine in the body. When a person taking MAO inhibitors consumes foods high in tyramine or certain medications, this can lead to a sudden and dangerous increase in blood pressure, manifesting as severe headaches. Given the severity of this side effect, it is critical for individuals on MAO inhibitors to be vigilant about any intense headaches, as they are not just a common discomfort but a signal of a serious medical emergency that needs prompt attention. Monitoring this aspect is essential for ensuring patient safety and preventing complications associated with high blood pressure. Other side effects, while they may require attention and management, do not pose the same immediate risk to health as severe headaches in this context.
