Quetiapine, marketed under the brand name Seroquel, is a widely prescribed atypical antipsychotic medication used to treat schizophrenia, bipolar disorder, and major depressive disorder [1].
When does Seroquel patent expire?
The primary patents protecting Seroquel expired in the United States in 2011, allowing for the introduction of generic versions of quetiapine [2].
Who makes generic quetiapine?
Numerous pharmaceutical manufacturers produce generic quetiapine. These companies include Teva Pharmaceuticals, Mylan Pharmaceuticals, Aurobindo Pharma, and various others [3].
How does quetiapine work?
Quetiapine is thought to exert its effects by altering the activity of certain neurotransmitters in the brain, including dopamine and serotonin. By balancing these chemicals, it helps to manage symptoms of psychiatric disorders [1].
What are the side effects of quetiapine?
Common side effects associated with quetiapine use can include drowsiness, dizziness, dry mouth, constipation, weight gain, and blurred vision [1]. More serious side effects, though less common, can include movement disorders, metabolic changes, and a condition called neuroleptic malignant syndrome [4].

Quetiapine is available in immediate-release and extended-release formulations. Dosing varies significantly depending on the condition being treated and individual patient response, with titration typically required [1].
What is the cost of quetiapine?
The cost of quetiapine can vary widely. Branded Seroquel is generally more expensive than its generic counterparts. The price of generic quetiapine is influenced by the manufacturer, dosage, and insurance coverage [5].

Can quetiapine be used for other conditions?
While primarily approved for schizophrenia, bipolar disorder, and major depressive disorder (as an adjunct therapy), off-label uses of quetiapine have been explored for conditions like anxiety and insomnia, though these are not FDA-approved indications [1].
What are the alternatives to quetiapine?
Alternative medications for schizophrenia and bipolar disorder include other atypical antipsychotics like olanzapine, risperidone, and aripiprazole, as well as older typical antipsychotics. For depression, alternative adjunct therapies or different antidepressant classes may be considered [1].
