What is a common adverse effect linked to Selective Serotonin Reuptake Inhibitors (SSRIs)?

Selective Serotonin Reuptake Inhibitors (SSRIs) are commonly prescribed for the treatment of depression and anxiety disorders. One well-known adverse effect associated with the use of SSRIs is gastrointestinal disturbances, including diarrhea. This can occur due to increased serotonin levels in the intestines, which can affect motility and lead to changes in bowel habits.

Diarrhea may not be experienced by all patients using SSRIs, but it is reported frequently enough to be considered a common adverse effect. This highlights the importance of monitoring gastrointestinal symptoms when initiating treatment with SSRIs.

The other options do not accurately reflect common adverse effects associated with SSRIs. Increased energy production is not typically linked with SSRIs as they may induce fatigue in some individuals. Enhanced cognitive function is usually not a direct result of SSRIs, and while some may experience improvement in their mood and cognitive clarity over time, cognitive enhancement is not an established or direct effect. Lastly, hypersomnia, or excessive daytime sleepiness, could occur for some patients, but it is not as common as diarrhea with this class of medications. Thus, diarrhea stands out as a well-documented and frequent adverse effect among SSRIs.
