If you experience unusual irritation, concern, anxiety, and sleep disorder, these are probably the signs of a psychosis. The psychosis symptoms may be reduced at the early stage, if Seroquel is taken in time.

General description

Seroquel is a medicine from the group of atypical antipsychotic agents of the new generation and provides a mild action and is well tolerated by most patients. The medicine contains quetiapine which interacts with many neurotransmitters and receptors in the brain.

The pharmacological action of Seroquel is conditioned by the influence on serotonin and dopamine receptors. A stimulation or inhibition of these receptors controls an agitation of neurons in the central nervous system, and this has a positive influence on the mental and emotional state of a human.

According to some reports, Seroquel is the most optimal choice in the treatment of psychoses in terms of the safety. It does not cause an intense sedative or agitating action. It acts softly and does not cause side effects during the use in the therapeutic doses.

Indications for the use

  • Treatment and prevention of acute/chronic schizophrenia
  • Treatment of manic episodes
  • Treatment and prevention of bipolar disorder
  • Treatment of acute psychoses
  • Treating depression (in combination with antidepressants)

In what dose is Seroquel used?

To treat acute psychoses and schizophrenia, Seroquel is used according to the following scheme:

  • 1 day: take 1 tablet of Seroquel 25 mg in the morning and evening
  • 2 day: take 1 tablet of Seroquel 50 mg in the morning and evening
  • 3 day: take 1 tablet of Seroquel 100 mg in the morning and evening
  • 4 day: take 1 tablet of Seroquel 150 mg in the morning and evening

Then, one daily dose is selected depending on the intensity of the antipsychotic effect. The maximal daily dose of Seroquel is 750 mg 2 times per day. If acute psychoses, the treatment usually lasts for 7-10 days. If schizophrenia or bipolar disorders, Seroquel may be used within 8 weeks.
