It acts to help control the mania, hypomania, depression, and psychosis associated with the condition.?? Lithium is a naturally occurring element that was found, in the late 1800s, to have mood-stabilizing properties. The first paper on using lithium to treat what was then called manic depression was published in 1949. The FDA approved lithium in 1970. Even now, the specific way lithium helps people with bipolar disorder is complex and not fully understood. When Is Lithium Prescribed? This drug is formally approved to treat manic episodes of bipolar disorder when symptoms such as grandiosity, racing thoughts, hypersexuality, delusions, hallucinations, and decreased need for sleep appear. However, it has also been shown to help with depressive symptoms, psychotic features, and mixed episodes. Some research has shown that lithium can also be useful in treating unipolar depression (depression without the mania seen in bipolar disorder) when added to one or more other depression medications, so doctors sometimes prescribe it for this, too.??

All patients should be screened for kidney problems before starting lithium and should be screened regularly while taking it as well.

If kidney problems develop later, your doctor may consider discontinuing lithium, since it may be possible to reverse the damage once you stop taking the medication.
