###Human: Does Seroquel extend the time of my derealization last longer? ###Assistant: Hello. Seroquel is Quetiapine and is an antipsychotic drug, but the drug is also used in mood disorders like bipolar disorder or resistant depression. The drug does not make a person schizophrenic. A lot of psychiatrists use this drug as augmentation therapy for depression or insomnia. If they have prescribed this drug, then remain relaxed. This will not cause any harm to your mental health but will help you. The drug is safe to use and has no severe side effects.
