Quetiapine is an atypical antipsychotic drug that is used to treat patients with schizophrenia as well as mania and depression related to bipolar disorder. Extended-release quetiapine is prescribed to treat depression.

Quetiapine is prescribed to treat symptoms of schizophrenia. It is also prescribed to treat mania and depression symptoms associated with bipolar disorder. When prescribed as an extended-release tablet, quetiapine can be used to treat depression in adults.

Quetiapine is classified as an atypical antipsychotic. It works by increasing levels of serotonin and dopamine in the brain. Serotonin and dopamine are neurotransmitters that help regulate mood. Balancing these chemicals’ levels in the brain can work to reduce symptoms of schizophrenia, bipolar disorder, and major depressive disorder (depression).

Quetiapine is prescribed in conjunction with other medications and psychotherapy (“talk therapy”).

Quetiapine is available as an oral tablet and an extended-release tablet.

Follow your healthcare provider's instructions regarding dosage and schedule. Do not exceed the prescribed dose or frequency of use without consulting your provider.

Quetiapine is used to manage schizophrenia, bipolar disorder, and major depressive disorder (as an adjunct therapy). The effects can be noticeable within a few weeks, but it may take up to four to twelve weeks for the full therapeutic effect to occur.

Continue using quetiapine as prescribed, even if you start feeling better. Regular use according to your prescription is crucial for the management of your condition.

While quetiapine is primarily used for treating schizophrenia, bipolar disorder, and major depressive disorder, healthcare providers may prescribe it off-label for other conditions such as anxiety or insomnia.

Discuss any alternative uses of quetiapine with your healthcare provider.

Quetiapine is available in the following dosage forms:

• Oral tablets
  
• Extended-release tablets
  
  

Quetiapine is a prescription medication. You must have a valid prescription from a licensed healthcare provider to obtain it.
