Summary
Quetiapine is used to treat schizophrenia, which is a mental disorder causing hallucinations and delusions, bipolar disorder, which involves extreme mood swings, and major depressive disorder, which is a severe form of depression.
Quetiapine works by affecting neurotransmitters, which are chemicals that transmit signals in the brain. It primarily targets dopamine and serotonin receptors, helping to balance these chemicals and reduce symptoms like hallucinations and mood swings.
Quetiapine is usually taken orally as a tablet, once or twice daily, with or without food. The starting dose for adults is typically 25 mg twice daily, and the maximum recommended dose is 800 mg per day.
Common side effects of Quetiapine include drowsiness, which is feeling very sleepy, dizziness, which is feeling lightheaded, dry mouth, and weight gain. These effects are usually mild to moderate.
Quetiapine can increase the risk of suicidal thoughts, especially in young people. It should not be used by those allergic to it or with severe liver problems. Caution is needed for heart conditions, and it's not recommended for elderly patients with dementia-related psychosis.
