Maintenance doses for bipolar are typically around what relative to those in schizophrenia?

• A. Twice as high
• B. About half
• C. The same
• D. One quarter

Answer: (B)

In maintenance treatment, the amount of medication needed to keep symptoms from flaring differs because the goals are different. For schizophrenia, keeping psychosis suppressed over the long term often requires higher levels of antipsychotic exposure, so maintenance doses tend to be higher. In bipolar disorder, the aim is to prevent mood episodes (mania, depression, or mixed states), and many patients achieve stability with lower antipsychotic exposure. Using higher doses increases the risk of extrapyramidal symptoms, weight gain, metabolic problems, sedation, and other side effects without giving proportional extra benefit for mood stabilization. For this reason, maintenance doses in bipolar disorders are typically about half of those used in schizophrenia.
