Quetiapine is an atypical antipsychotic. It’s not completely known how Quetiapine works, but it’s thought to work by balancing out the levels of chemicals (dopamine and serotonin) in your brain to help control your thoughts, mood, and behaviors.

• Schizophrenia (adults and children): The typical starting dose is to take 25 mg by mouth twice daily. Your provider will raise your dose slowly over time. The typical maintenance dose ranges from 150 mg to 800 mg daily, divided into smaller doses and taken twice to three times throughout the day
• Bipolar I disorder (adults and children): The typical starting dose ranges from 25 mg to 50 mg by mouth twice daily, depending on age and whether or not you’re taking other medications for bipolar disorder. Your provider will raise your dose slowly over time. The typical maintenance dose ranges from 400 mg to 800 mg daily, divided into smaller doses and taken twice to three times throughout the day
