Which drug is a mood stabilizing medication used to treat bipolar disorder?

• A. Lithium
• B. Haldol
• C. Prozac
• D. Xanax

Answer: (A)

Mood stabilization aims to keep mood swings from cycling between mania and depression. Lithium is the classic mood stabilizer used in bipolar disorder because it helps prevent both manic and depressive episodes and can reduce suicide risk. It works over time, so it’s not for immediate crisis, and it has a narrow therapeutic index, meaning blood levels must be regularly checked along with kidney and thyroid function. Patients on lithium need consistent hydration and salt intake, and should be aware of toxicity signs such as tremor, confusion, vomiting, or coordination problems, which require prompt medical attention. The other medications listed are not mood stabilizers: haloperidol is an antipsychotic, fluoxetine is an antidepressant, and alprazolam is a benzodiazepine anxiolytic; they may be used for symptoms or specific situations in bipolar treatment but do not serve the mood-stabilizing role that lithium does.
