What is a notable side effect of the use of SNRIs related to energy levels?

SNRIs, or Serotonin-Norepinephrine Reuptake Inhibitors, function by increasing the levels of both serotonin and norepinephrine in the brain. Norepinephrine, in particular, plays a significant role in regulating arousal and alertness, which often leads to increased energy and focus in patients. This energizing effect is one reason SNRIs are utilized in treating conditions such as depression and anxiety, where fatigue and lack of motivation are prevalent symptoms.

The increase in norepinephrine can help alleviate symptoms associated with low energy levels, promoting a more active and engaged state in patients. Understanding the impact of these neurotransmitters is crucial for managing symptoms effectively and tailoring treatment to enhance overall functioning in individuals suffering from mood disorders.
