What condition is lithium (Lithane) commonly used to treat?

Lithium is a mood stabilizer that is primarily used in the treatment of bipolar disorder. It is highly effective in managing the manic and depressive episodes associated with this mental health condition. In addition to bipolar disorder, it has also shown utility in the treatment of major depressive disorder, especially when traditional antidepressants may not be effective on their own. Moreover, lithium is sometimes used to address mania and can have a role in treating certain cases of schizophrenia.

This broad application makes it a valuable medication in psychiatric care, as it not only helps stabilize mood but can also reduce the severity of manic episodes and prevent future relapses. The other conditions listed, such as heart failure and respiratory issues, chronic pain, and severe allergies, do not align with lithium's primary uses, which is why they are not applicable here. Understanding the specific indications for lithium can assist in recognizing its role in mental health management.
