Can quetiapine trigger psychosis?

Quetiapine is not known to trigger psychosis, which is a severe mental health condition characterized by a loss of touch with reality, such as hallucinations, delusions, or disorganized thinking.

In fact, quetiapine is often used to treat psychosis, along with other conditions such as bipolar disorder, major depressive disorder, and anxiety disorders. It works by blocking the activity of certain neurotransmitters in the brain, including dopamine and serotonin, which can help to regulate mood and behavior.

However, quetiapine can cause side effects, some of which may be similar to symptoms of psychosis, such as confusion, agitation, and disorientation. These side effects may be more common when starting the medication or when the dosage is increased, and may improve over time.

It is important to use quetiapine only under the guidance of a healthcare provider, who can help determine the appropriate dosage and monitor for potential side effects and interactions. If you are experiencing symptoms of psychosis or other severe mental health conditions, it is important to seek medical attention immediately.


There are various forms of drugs available, such as tablets or liquids, and each may have a separate patient information leaflet (PIL) for different doses. It is important to refer to the PIL for the specific form and dose of the drug that you have been prescribed.
