Is Seroquel a sleeping pill?

Seroquel (generic name: quetiapine) is another antipsychotic that is sedating and can cause moderate weight gain. In addition to Desyrel, many doctors offer Seroquel to their depressed patients for sleep because it is effective at tiny doses, it is not at all addictive, and research studies have demonstrated that Seroquel can sometimes help relieve unipolar major depression when added to antidepressants. (Neither Desyrel nor Seroquel are licensed as sleeping medications.)
