what are ssris

SSRIs, or selective serotonin reuptake inhibitors, are a type of antidepressant medication that are commonly prescribed to treat depression and other mental health conditions. They work by increasing levels of serotonin in the brain, which is a neurotransmitter that carries signals between nerve cells and is thought to have a positive influence on mood, emotion, and sleep. SSRIs block the reuptake of serotonin, meaning more of it is available to pass messages between nearby nerve cells. They are considered relatively safe and cause fewer side effects than other types of antidepressants. SSRIs are usually taken in tablet form and are often used in combination with talking therapies such as cognitive behavioral therapy.
