Bipolar Medications Library


Updated April 28, 2014

Seroquel Drug Information: Classification and Use

Seroquel - generic quetiapine fumarate - is classed as an atypical antipsychotic medication. It is used to treat psychotic symptoms of such illnesses as schizophrenia and schizoaffective disorder, including hallucinations, delusions, catatonia and paranoia. It is also approved for use in treating acute manic episodes of bipolar disorder with or without psychotic features, and has some antidepressant effects. Seroquel was made more efficient for acute mania by adding Lithium or Depakote to the therapy.

Seroquel Drug Warnings: Complications

Treatment with Seroquel is associated with the risk of some serious complications. These include:
  • Neuroleptic Malignant Syndrome (NMS), a potentially fatal illness whose symptoms include high fever, muscle rigidity, profuse sweating and dark urine. Read more: Neuroleptic Malignant Syndrome.

  • Tardive Dyskinesia, a movement disorder that may not go away unless treated promptly. Symptoms include uncontrolled movements of the lips and tongue. Read more: Tardive Dyskinesia.
