Basics
Seroquel is the brand of the generic drug quetiapine, used to treat schizophrenia and major affective disorder (formerly called manic-depression).
Seroquel changes the degree of neurotransmitters (naturally occurring brain substances) as well as serotonin and dopamine.
Seroquel belongs to a category of medicines referred to as atypical antipsychotics.
The Food and Drug Administration (FDA) approved quetiapine in 1997 as the brand Seroquel for drug manufacturer AstraZeneca.

Side Effects

Weight gain is a well-known side effect of taking Seroquel, and doctors have prescribed the drug off-label to treat anorexia. However, a study printed in European Eating Disorders Review in 2012 found that Seroquel failed to help folks with eating disorder gain weight, nor did it help ease their symptoms of anxiety or depression.

Moreover, there’s not enough proof to indicate that the advantages of Seroquel for off-label uses outweigh the risks related to the drug, finished a study printed in the Journal of Psychosocial Nursing and Mental Health Services in 2013.
