Question

scenario: a 45-year-old patient with bipolar disorder is on quetiapine but experiences substantial weight gain.
question: what is the best approach to address this side effect?

• switch to a different antipsychotic with a lower risk of weight gain.
• add a weight-loss medication.
• increase the dose of quetiapine.
• advise the patient to increase physical activity.

Explanation:

To address the weight - gain side effect of quetiapine in a bipolar - disorder patient, we need to consider the root cause. The weight gain is a side effect of the current antipsychotic (quetiapine). Switching to a different antipsychotic with a lower risk of weight gain targets the source of the problem. Adding weight - loss medication may have its own side effects and doesn't address the underlying issue of the antipsychotic's side effect. Increasing the quetiapine dose is likely to worsen the weight - gain problem as higher doses may intensify side effects. Advising increased physical activity is a good general measure but is not the most direct way to address the medication - related side effect compared to switching the medication to one with a lower weight - gain risk.

Answer:

A. Switch to a different antipsychotic with a lower risk of weight gain.
