Olanzapine — Uses, Dosage, Side Effects & Safety

Drug class: Mental Health & Psychiatry

Overview

Olanzapine is an atypical antipsychotic medication used to treat mental health conditions such as schizophrenia and bipolar disorder. It helps manage symptoms like hallucinations, delusions, mood swings, and agitation. Olanzapine works by balancing certain chemicals in the brain, particularly dopamine and serotonin, which are involved in mood, behavior, and thinking. This helps improve mood stability, reduce psychotic symptoms, and prevent relapses. Key points for patients: Olanzapine may take several days to weeks to show full benefits. It is important to take it regularly as prescribed, even if you feel better. Do not stop taking olanzapine suddenly without consulting your healthcare provider, as this can cause withdrawal symptoms or relapse.
