What Is Paroxetine?
Paroxetine is an antidepressant in the selective serotonin reuptake inhibitor (SSRI) class, prescribed primarily for depression, anxiety disorders, and similar conditions.
This medication works by increasing serotonin levels in the brain, which can help improve mood and energy levels. Brand names include Paxil and Seroxat. For a detailed overview, visit the Paroxetine Side Effects page.
