Which adverse effect is particularly detrimental for individuals taking antipsychotic or antidepressant medications?

• A. Overheating
• B. Hypothermia
• C. Dizziness only
• D. Nausea only

Answer: (A)

Overheating is the key risk because many antipsychotic and antidepressant medications blunt the body’s ability to regulate temperature. They can cause anticholinergic effects and autonomic changes that reduce sweating and impair heat dissipation, and some alter central temperature control. In hot environments or with exercise, this makes dangerous heat buildup more likely, potentially leading to heat exhaustion, heat stroke, dehydration, and organ stress. Dizziness or nausea can occur with these drugs but aren’t typically life-threatening temperature regulation problems, and hypothermia isn’t a common risk here. So overheating stands out as the most serious adverse effect to monitor in these patients.
