Paroxetine — Uses, Dosage, Side Effects & Safety

Drug class: Selective Serotonin Reuptake Inhibitor (SSRI) Antidepressant

Overview

Paroxetine is a prescription medication used to treat depression, anxiety disorders (such as generalized anxiety disorder, panic disorder, and social anxiety disorder), obsessive-compulsive disorder (OCD), post-traumatic stress disorder (PTSD), and premenstrual dysphoric disorder (PMDD). It belongs to a group of medicines called selective serotonin reuptake inhibitors (SSRIs), which help balance chemicals in the brain that affect mood and emotions. Paroxetine works by increasing the levels of serotonin, a natural substance in the brain that helps maintain mental balance. This can improve mood, sleep, appetite, and energy levels, and may help restore interest in daily living. Key points for patients: Paroxetine may take several weeks to show its full effect. Do not stop taking it suddenly without consulting your doctor, as this can cause withdrawal symptoms. Always take it as prescribed and report any unusual changes in mood or behavior to your healthcare provider.
