Quetiapine
Seroquel (quetiapine) is the only product on this shelf, listed in five tablet strengths from 25 mg to 300 mg for Schizophrenia and Bipolar I Disorder.
Key points
- The label carries a boxed warning that elderly patients with dementia-related psychosis face an increased risk of death from antipsychotics, and quetiapine is not approved for that use.
- For bipolar I mania, it is indicated both as monotherapy and as an adjunct to lithium or divalproex.
- The suicidality warning notes no increased risk in patients over 24, with a reduction in risk in those aged 65 and older.
How does Quetiapine work?
Quetiapine is an atypical antipsychotic that blocks receptors for dopamine and serotonin, the two chemical messengers involved in psychotic symptoms and mood swings. It appears under Antidepressants on this shelf because of its listed use in major depressive disorder.
For someone taking it, that means a reduction in hallucinations and delusions in schizophrenia, and a calming of the elevated, irritable state of a manic episode. The full effect on mood can take one to two weeks to build.
