What is trazodone?
Trazodone is an antidepressant that belongs to a group of drugs called selective serotonin reuptake inhibitors (SSRIs). It affects chemicals in the brain that may be unbalanced in people with depression.
Trazodone is used to treat major depressive disorder. It may help to improve your mood, appetite, and energy level as well as decrease anxiety and insomnia related to depression.
Trazodone works by helping to restore the balance of a certain natural chemical (serotonin) in the brain.
