Which of the following is NOT typically a side effect of antidepressants?

Antidepressants can have various side effects, and understanding which effects are commonly associated with these medications is crucial for both practitioners and patients. Low blood pressure is not typically recognized as a standard side effect of most antidepressants. While some medications may have cardiovascular impacts that could theoretically lead to changes in blood pressure, they usually do not cause low blood pressure as a general rule among the majority of antidepressants.

In contrast, the other options listed are known side effects of antidepressants. Increased appetite may occur, particularly with certain types of antidepressants, leading to weight gain in some patients. Photosensitivity can be a side effect, especially with specific types of medications. Dry mouth is also a common complaint among those taking antidepressants, due to the anticholinergic effects these drugs can have, leading to reduced saliva production.

Therefore, understanding that low blood pressure is generally not associated with the use of antidepressants helps clarify why it is the correct choice in this context.
