Selective serotonin reuptake inhibitors are a group of medications. They are usually called SSRIs. They are used to treat depression, anxiety disorders, and some other problems.
In many countries, SSRIs are prescribed more often than any other type of antidepressant.[1]
Examples of common SSRIs are fluoxetine (Prozac), paroxetine (Paxil), citalopram (Celena), and escitalopram (Lexapro).
