Seroquel, generically known as quetiapine, is an oral antipsychotic medication used to treat mental health conditions. Seroquel can be used to treat bipolar disorder, schizophrenia, and major depressive disorder. It was developed in the early 1990s by AstraZeneca and has since become one of the most prescribed medications for these psychiatric illnesses.

Quetiapine belongs to a group called anti-psychotic drug (atypical type). Anti-psychotic drugs work by balancing dopamine and serotonin levels in the brain to help alleviate symptoms like hallucinations, delusions and thought disorders.

Seroquel (Quetiapine) is a medication used to reduce hallucinations and improve concentration. It can help improve cognitive functioning, reduce anxiety, and increase engagement in daily activities. Seroquel can help regulate mood, improve sleep quality, increase appetite, and increase energy levels. Furthermore, Quetiapine can help prevent or reduce the severity and frequency of mood swings.

Uses and Dosage

Seroquel (Quetiapine) is available in the form of tablets and should be taken orally as prescribed by your doctor, typically 2 or 3 times per day with or without food. Seroquel (Quetiapine) tablets should be swallowed whole, as chewing, crushing, or breaking the tablet can reduce its effectiveness. It is important to follow your doctor's instructions for taking this medication for the best results.

The dosage of Seroquel (quetiapine) is based on the individual patient's medical condition and response to treatment.
