What is Quetiapine?

How Quetiapine Tablet Works

Quetiapine is a medication that helps balance certain chemicals in the brain, which can improve mood, thinking, and behaviour. It is commonly used to treat conditions like schizophrenia, bipolar disorder, and sometimes depression.

Quetiapine works by affecting neurotransmitters (natural chemicals in the brain) called dopamine and serotonin. By balancing these, it can help reduce symptoms like hallucinations, mood swings, and excessive thoughts.

Think of it as a "stabiliser" for your brain, helping it stay balanced and calm, which can make it easier to manage emotions and feel more in control.

Can I Take Quetiapine with Other Medicines?

Quetiapine can interact with many drugs, such as:

• Alcohol
• Antibiotics like moxifloxacin
• Antidepressants
• Antifungal medications like itraconazole, ketoconazole
• Antihistamines like cetirizine or diphenhydramine
• Amiodarone
• Carbamazepine
• Grapefruit juice
• Opioid pain relievers like codeine, hydrocodone
• Phenytoin 
• Sotalol
• Thioridazine

Doctors use different doses of quetiapine depending on the condition being treated. 

For schizophrenia in adults, doctors usually start with 25mg twice a day, gradually increasing to 300-400 mg daily in divided doses. The maintenance dose ranges from 150 to 750mg per day.
