Quetiapine 300mg Tablets

Doctors prescribe Quetiapine 300mg tablets to treat schizophrenia in adults and children aged 13 years and older. They also use it alone or with divalproex or lithium to manage manic or depressive episodes in individuals with bipolar disorder, a condition characterized by alternating periods of depression, mania, and other abnormal moods.

Moreover, doctors combine quetiapine with other medications to prevent depressive episodes in patients with bipolar disorder. Additionally, doctors use quetiapine extended-release alone to treat manic episodes in children with bipolar disorder starting at age 10. Furthermore, doctors use quetiapine extended-release with antidepressants to treat major depressive disorder in adults. In children and teenagers, quetiapine tablets help treat bipolar disorder and schizophrenia. Quetiapine, an atypical antipsychotic, alters the activity of specific natural chemicals in the brain.
