Quetiapine, commonly sold under the brand name Seroquel, is a type of prescription medication called an antipsychotic drug. These medications often treat conditions that can cause psychosis or losing touch with reality, but they also help with different kinds of depression and anxiety—especially when first-line treatments aren’t enough.
There are two types of antipsychotic drugs. “Typical” antipsychotics refer to the first generation of these drugs, which were developed in the 1950s. “Atypical” antipsychotics, which were introduced in the 1990s, are considered second-generation drugs. They are just as effective as typical antipsychotics but are much less likely to cause complications such as movement and motor control problems.
Quetiapine is an atypical antipsychotic. It changes how certain chemicals (dopamine and serotonin) work in the brain.
Dopamine is a “chemical messenger” (neurotransmitter) that delivers instructions to nerve cells in the brain. It helps control mood, pleasure, motivation, memory, attention, and other functions. Serotonin is also a chemical messenger. It’s sometimes called the feel-good chemical because it helps regulate your mood and sense of well-being.
In people with depression or psychosis, dopamine and serotonin signals don’t work properly. Quetiapine works by blocking these abnormal signals.
Quetiapine (Seroquel) treats depressionHow quetiapine works
The goal of a antipsychotic is to work more efficiently than a typical drug on making you feel better and more confident. That’s because the abnormal signals that occur in a person with schizophrenia or depression are more likely to happen in someone with both schizophrenia and depression.
Dopamine and serotonin are important brain chemicals. They also play a role in motor control, attention, and memory.
People with schizophrenia and depression often lose touch with reality because of a lack of dopamine and serotonin. Quetiapine works only on making people feel better.
Quetiapine (Seroquel) helps with hallucinations, delusions, and social problemsHow long does quetiapine take to work for you?
Quetiapine may start to work within a couple of weeks for people with schizophrenia or depression to lose their appetite and achieve better results. It may take several weeks for quetiapine to see the full effects of an antipsychotic drug on a person’s mental health.
However, people with schizophrenia and depression usually take an antipsychotic for only a few weeks. Quetiapine works best when started within the first one to two weeks of beginning an antipsychotic drug. If you take an antipsychotic for only a few weeks, your risk of movement problems will decrease.
Can you take quetiapine for a long time?
Quetiapine is a long-term treatment. It’s important to talk to a doctor before taking an antipsychotic drug, since it can be dangerous if you take it for too long.
Quetiapine (Seroquel) works best when started a few weeks after beginning an antipsychotic drugDoes quetiapine make you confident or confident at all?
Quetiapine helps people with hallucinations and delusions for about four weeks. However, it can take up to two years for the medication to be as effective as it is for treating a person’s mental health.
If someone takes an antipsychotic for more than four weeks, the risk of movement problems increases. Quetiapine also helps people with psychosis lose touch with reality because of a lack of serotonin.
Quetiapine works only on first-line antipsychotic drugs. It doesn’t protect you from sexually transmitted diseases, such as HIV or the introduction of gonolasporomas.
How long does quetiapine last?
Quetiapine is effective for about 4-6 weeks for losing your appetite and improving the amount of energy you have. It may take several weeks for quetiapine to feel noticeable.

Balancing these chemicals’ levels in the brain can work to reduce symptoms of schizophrenia, bipolar disorder, and major depressive disorder (depression).
Quetiapine is prescribed in conjunction with other medications and psychotherapy (“talk therapy”).
Quetiapine is available as an oral tablet and an extended-release tablet.

Side EffectsThe use of quetiapine can lead to various side effects in some individuals.
As a group of medications used to treat clinically diagnosed psychotic disorders (i.e., mental/mood disorders), antipsychotics are regularly prescribed for the treatment of conditions including schizophrenia, major depressive disorder, and various forms of psychosis. Seroquel and Zyprexa are two medications that fall into the classification of antipsychotics; both drugs may help individuals who need them achieve reduced psychotic symptoms such as hallucinations, delusions, and manic and depressive episodes. In the United States alone, about 7 million people take antipsychotic medications such as Seroquel and Zyprexa to help manage their symptoms. There are benefits and potential drawbacks to using each, some of which we will cover below. Continue reading to learn about what Seroquel and Zyprexa are, how Seroquel and Zyprexa differ from one another and how they are similar, and how DNA testing can help you decide whether Seroquel or Zyprexa may be better for you.
Seroquel vs Zyprexa: What are They?
According to the National Institute of Mental Health, about three out of every 100 people will experience a form of psychosis at some point in their lives. The term “psychosis” may refer to hallucinations (such as hearing, seeing, smelling, tasting, or having a sensation about something that is not real or present) but could also include paranoia, delusions, and disordered thoughts and speech. Medications such as Seroquel and Zyprexa were developed to address the parts of the brain associated with hallucinogenic thoughts and psychosis and help reduce or eliminate them. There are various ways to treat psychosis; some people seek talk therapy in the form of cognitive behavioral therapy (CBT) with individual or group therapy. Others layer on antipsychotic medications such as Seroquel or Zyprexa.
Both Quetiapine (Seroquel) and Olanzapine (Zyprexa) may be helpful for the aforementioned conditions and the symptoms associated with them, but how they interact with individuals depends on individualized metabolisms, body chemistry makeup, and many other factors.
