This antidepressant medication is prescribed for depression and is widely used off-label to treat insomnia because of its sedating properties. It works primarily by blocking serotonin receptors and inhibiting serotonin reuptake in the brain, with relatively little effect on other neurotransmitters. Unlike many sleep aids, it is generally not habit-forming.

Sertraline combined with trazodone may increase the risk of serotonin syndrome due to additive serotonergic effects.
