SSRIs, or serotonin reuptake inhibitors, regulate the amount of serotonin in the brain to help treat depression. These antidepressants help those struggling with depression symptoms but stopping SSRI usage can be very challenging. It is essential you speak to your doctor before you stop taking your prescribed SSRI antidepressant medication, as there are many withdrawal symptoms associated with SSRI drug withdrawals, which is called SSRI discontinuation syndrome.
