Antidepresanlar are medications used to treat depression and other mood disorders. They work by balancing chemicals in the brain, such as serotonin and norepinephrine, which affect mood and emotions. Common types include SSRI (Selective Serotonin Reuptake Inhibitors) and SNRI (Serotonin-Norepinephrine Reuptake Inhibitors). These medications can help improve symptoms like sadness, anxiety, and lack of interest in daily activities. However, they may take several weeks to show effects and can have side effects. It's important for individuals to consult with a healthcare professional to find the right treatment for their needs.
