Quetiapine — Uses, Dosage, Side Effects & Safety

Drug class: Atypical antipsychotic

Overview

Quetiapine is an atypical antipsychotic medication used to treat mental health conditions such as schizophrenia, bipolar disorder (including manic and depressive episodes), and as an add-on treatment for major depressive disorder in adults. It helps to balance certain chemicals in the brain, which can improve mood, thinking, and behavior. Quetiapine works by affecting neurotransmitters like dopamine and serotonin, which are involved in mood regulation and perception. It can help reduce hallucinations, delusions, mood swings, and improve concentration. Key points for patients: Quetiapine should be taken exactly as prescribed, and it may take several weeks to notice full benefits. Do not stop taking it suddenly without consulting your doctor, as this can cause withdrawal symptoms or worsening of your condition.
