Zoloft is the brand name for sertraline, a selective serotonin reuptake inhibitor (SSRI) commonly prescribed to treat depression, anxiety disorders, panic attacks, and obsessive-compulsive disorder (OCD). It works by increasing the levels of serotonin in the brain, which can help improve mood and emotional well-being. Zoloft is typically taken as a daily oral medication and may take several weeks to show its full effects. Like all medications, it can have side effects, and it’s important to use it under the guidance of a healthcare professional.
