What is quetiapine mainly used for?

Quetiapine is mainly used for the treatment of several mental health conditions, including:

  1. Schizophrenia: Quetiapine can help to reduce symptoms such as hallucinations, delusions, and disordered thinking in individuals with schizophrenia.
  2. Bipolar disorder: Quetiapine can help to regulate mood swings, reduce manic and depressive symptoms, and prevent relapse in individuals with bipolar disorder.
  3. Major depressive disorder: Quetiapine may be used as an adjunct treatment for depression in individuals who have not responded adequately to other antidepressant medications.
  4. Anxiety disorders: Quetiapine may be used off-label to treat anxiety disorders, such as generalized anxiety disorder and post-traumatic stress disorder (PTSD).

In addition, quetiapine may be used off-label to treat other conditions, such as insomnia and borderline personality disorder. However, the use of quetiapine for these conditions should be discussed with a healthcare provider, who can help determine the most appropriate treatment plan based on individual needs and medical history.


There are various forms of drugs available, such as tablets or liquids, and each may have a separate patient information leaflet (PIL) for different doses. It is important to refer to the PIL for the specific form and dose of the drug that you have been prescribed.
