Adults The information below is derived from a clinical trial database for quetiapine consisting of over 4,300 patients.
This database includes 698 patients exposed to quetiapine for the treatment of bipolar depression, 405 patients exposed to quetiapine for the treatment of acute bipolar mania (monotherapy and adjunct therapy), 646 patients exposed to quetiapine for the maintenance treatment of bipolar I disorder as adjunct therapy, and approximately 2600 patients and/or normal subjects exposed to 1 or more doses of quetiapine for the treatment of schizophrenia.
Of these approximately 4,300 subjects, approximately 4000 (2300 in schizophrenia, 405 in acute bipolar mania, 698 in bipolar depression, and 646 for the maintenance treatment of bipolar I disorder) were patients who participated in multiple dose effectiveness trials, and their experience corresponded to approximately 2400 patient-years.
The conditions and duration of treatment with quetiapine varied greatly and included (in overlapping categories) open-label and double-blind phases of studies, inpatients and outpatients, fixed-dose and dose-titration studies, and short-term or longer-term exposure.
Adverse reactions were assessed by collecting adverse reactions, results of physical examinations, vital signs, weights, laboratory analyses, ECGs, and results of ophthalmologic examinations.
The stated frequencies of adverse reactions represent the proportion of individuals who experienced, at least once, an adverse reaction of the type listed.
5 WARNINGS AND PRECAUTIONS Cerebrovascular Adverse Reactions: Increased incidence of cerebrovascular adverse reactions (e.g., stroke, transient ischemic attack) has been seen in elderly patients with dementia-related psychoses treated with atypical antipsychotic drugs ( 5.3 ) Neuroleptic Malignant Syndrome (NMS): Manage with immediate discontinuation and close monitoring ( 5.4 ) Metabolic Changes: Atypical antipsychotics have been associated with metabolic changes.
These metabolic changes include hyperglycemia, dyslipidemia, and weight gain ( 5.5 ) Hyperglycemia and Diabetes Mellitus: Monitor patients for symptoms of hyperglycemia including polydipsia, polyuria, polyphagia, and weakness.
Monitor glucose regularly in patients with diabetes or at risk for diabetes Dyslipidemia: Undesirable alterations have been observed in patients treated with atypical antipsychotics.
Appropriate clinical monitoring is recommended, including fasting blood lipid testing at the beginning of, and periodically, during treatment Weight Gain: Gain in body weight has been observed;
clinical monitoring of weight is recommended Tardive Dyskinesia: Discontinue if clinically appropriate ( 5.6 ) Hypotension: Use with caution in patients with known cardiovascular or cerebrovascular disease ( 5.7 ) Increased Blood Pressure in Children and Adolescents: Monitor blood pressure at the beginning of, and periodically during treatment in children and adolescents ( 5.9 ) Leukopenia, Neutropenia and Agranulocytosis: Monitor complete blood count frequently during the first few months of treatment in patients with a pre-existing low white cell count or a history of leukopenia/neutropenia and discontinue quetiapine at the first sign of a decline in WBC in absence of other causative factors ( 5.10 ) Cataracts: Lens changes have been observed in patients during long-term quetiapine treatment.
Like all medications, Quetiapine Fumarate can cause side effects. However, not everyone who takes this medication will experience them. Many side effects are dose-dependent and may improve as your body adjusts to the medication. Others may require dose adjustment or medical attention.
