Seroquel is the brand name of a drug called quetiapine, an antipsychotic medication that works by changing the actions of some natural chemicals (dopamine and serotonin) in the brain to improve mood, thinking, and behavior.
It was developed in 1985 and the US Food and Drug Administration originally approved it for medical use in the United States in 1997.
This medication is produced by AstraZeneca, an Anglo–Swedish multinational biopharmaceutical and pharmaceutical company.
It is used together with antidepressant drugs to treat the major depressive disorder (MDD) in adults. The major depressive disorder is the clinical term for a mood disorder described by protracted periods of low self-esteem, sadness, and in rare cases, the urge to commit suicide.
The symptoms of MDD are defined as lasting at least 12 days, however, they commonly go on much longer.
This medication is also used to treat bipolar disorder (once known as manic-depressive disorder or manic depression) in children who are at least 10 years old and adults.
Bipolar disorder causes serious shifts in energy, mood, behavior, and thinking — from the lows of depression to the highs of mania, on one extreme or the other.
Moreover, this antipsychotic medication is used to treat schizophrenia in children who are at least 13 years old and adults. Schizophrenia is a severe disorder that affects how a person feels, thinks, and acts.
This condition most commonly strikes between the ages of 16 and 30 and affects an estimated 1% of the population. Signs and symptoms of schizophrenia may include:
- lack of motivation;
- trouble speaking clearly;
- little desire to be around other people;
- trouble making sense;
- disorganized thinking;
- delusions – beliefs which are not true;
- hallucinations – imagined images or voices which seem real.
Also, prescribing this medication as a sleep aid is a fairly common practice by a lot of doctors. However, it is not approved for the treatment of dementia-related behavior problems.
For depressive episodes associated with bipolar disorder, the usual recommended initial dosage is 50 mg once per day, typically at bedtime.
Starting the second day, the usual recommended dose is 100 mg once per day, then increases to 200 mg once per day. The maximum dose is 300 mg per day.
For manic episodes associated with bipolar disorder, the usual recommended initial dose is 50 mg two times per day.
Starting the second day, the usual recommended dose is 100 mg per day. After day four of treatment, the usual recommended dose is 200 mg per day. The maximum dose is 800 mg per day.
For schizophrenia, the usual recommended initial dose is 25 mg two times per day. The dosage is increased to 300 to 400 mg per day.
If you miss a dose, take it as soon as you remember. Do not intake 2 doses at the same time unless your doctor tells you to.
If you take too much this antipsychotic medication, call the local Poison Control Center or doctor, or seek emergency medical attention.
