Which medication is commonly used as a mood stabilizer in bipolar disorder?

Lithium is the standout mood stabilizer for bipolar disorder because it helps steady mood across both manic and depressive episodes and has robust evidence for reducing suicide risk. It works by modulating neuronal signaling in ways that calm extreme mood shifts over time, rather than just treating symptoms temporarily. Because it has a narrow therapeutic window, it requires regular blood tests to keep levels in the safe range and periodic checks of kidney and thyroid function, since lithium can affect those organs. Early signs of toxicity include tremor, nausea or vomiting, confusion, coordination problems, and blurred vision, so any of these warrant prompt medical attention and potential dose adjustment. The other medications listed aren’t mood stabilizers used for long-term bipolar management. An antipsychotic like haloperidol can help control acute mania or agitation but isn’t primarily used for maintenance mood stabilization. An antidepressant such as fluoxetine can treat depressive symptoms but may trigger mania if used alone in bipolar disorder. A benzodiazepine like clonazepam is helpful for anxiety or sleep issues but does not provide long-term mood stabilization.
