What is Seroquel?
Seroquel (quetiapine) is an antipsychotic medicine. It works by changing the actions of chemicals in the brain.
Seroquel is used to treat schizophrenia in adults and children who are at least 13 years old.
Seroquel is used to treat bipolar disorder (manic depression) in adults and children who are at least 10 years old.
Seroquel is also used together with antidepressant medications to treat major depressive disorder in adults.

Never take Seroquel in larger amounts, or for longer than recommended by your doctor. High doses or long-term use can cause a serious movement disorder that may not be reversible. Symptoms of this disorder include tremors or other uncontrollable muscle movements.
