Review Lithium's mechanism of action in treating bipolar disorder, as well as lithium toxicity.
Lithium is a mood stabilizing drug used to treat bipolar disorder. It has a narrow therapeutic range, and toxicity symptoms start to show up above a blood level of 1.5. Things that can cause lithium toxicity include fluid loss like dehydration and diuretics, low sodium levels, decreased kidney function, or the specific use of NSAIDs or thiazide diuretics. Early signs of lithium toxicity include GI distress, which includes nausea, vomiting, and diarrhea. Late signs of toxicity are neurological problems, like loss of coordination, sedation, confusion, or seizures. Lithium is also teratogenic and should not be given during pregnancy.
