Lithium Toxicity
Medically reviewed by Drugs.com. Last updated on Jul 7, 2024.
Lithium toxicity happens when the amount of lithium in your blood is too high. Lithium is a medicine that is used to treat depression and bipolar disorder. Toxicity can occur if you take a large dose of lithium at one time. Toxicity can also be caused by taking a slightly higher dose of lithium over time. It can also occur if you are dehydrated, or you take other medicines that cause lithium to build up in your blood. A decreased intake of sodium (salt) can also lead to lithium toxicity.
