How does it work?

Dopamine is a chemical messenger (“neurotransmitter”) in the brain that is primarily involved in thinking, emotions, behavior and perception.

In some diseases, there can be too much dopamine, leading to unwanted symptoms. The main effect of quetiapine is to block the action of dopamine in the brain, resulting in a reduction in symptoms.

Quetiapine Seroquel Tablets also affect other neurotransmitters in the brain such as serotonin and its positive effects may also be related.

How is it used?

Seroquel tablets are taken regardless of meals and once or twice a day, depending on the condition.

What is Seroquel?

Seroquel is a potent and well-tolerated atypical antipsychotic that contains the active ingredient quetiapine.

Areas of application of Seroquel tablets

  • treatment of acute and chronic psychoses, including schizophrenia;
  • treatment of manic episodes in bipolar disorder;
  • treatment of moderate to severe depressive episodes associated with bipolar disorder (within 8 weeks).

Quetiapine Seroquel was developed in England by the chemical company ICI and patented in 1987. Its advantage over antipsychotics developed in the 1950s was a milder side effect profile. Short-term side effects of quetiapine include drowsiness, dry mouth, dizziness, and low blood pressure when standing. The duration of these effects is about six hours. The information about quetiapine warns against drinking it with grapefruit juice, since this juice blocks the metabolism of the drug in the intestines, which leads to an increase in the effect of the drug. Long-term side effects of Seroquel's active ingredient quetiapine include weight gain, high blood sugar and an increased risk of diabetes. With regular use of quetiapine, withdrawal symptoms occur when the drug is stopped, such as nausea, insomnia, headache, diarrhea, vomiting, dizziness, and irritability.

Seroquel for sleep

Quetiapine Seroquel tablets are often prescribed off-label at low doses, ie not for the treatment of mental illness. Most often, such use is due to the main side effect of the drug, namely drowsiness. The sleep benefits of Seroquel active ingredient quetiapine have been noted in war veterans, with military personnel reporting a decrease in nightmares and anxiety. Some even reported sleeping more than six hours for the first time since returning from the war. However, there have been reports of deaths in the United States of veterans taking quetiapine.

For depression, I was prescribed the antipsychotic Seroquel in combination with an antidepressant. One 25 mg tablet is enough for me to sleep well at night. Seroquel does not cause any side effects for me, which surprised me positively. If you only use one tablet a day, the price of the treatment is not so high.
