Sertraline is a selective serotonin reuptake inhibitor (SSRI) antidepressant commonly prescribed for several mental health conditions. It helps improve symptoms of depression, obsessive-compulsive disorder (OCD), panic disorder, post-traumatic stress disorder (PTSD), premenstrual dysphoric disorder (PMDD), social anxiety disorder, and generalized anxiety disorder. By increasing serotonin levels in the brain, sertraline can positively affect mood and emotional state. It is available under brand names such as Zoloft and is often prescribed as a first-line treatment due to its favorable safety profile compared to older antidepressants. Sertraline is also frequently chosen for its minimal impact on weight gain and cognitive function, making it widely used globally for its efficacy and well-established clinical benefits.
