Lithium Toxicity · California Poison Control System (CPCS)

WebLithium is excreted primarily in urine with less than 1% being eliminated with the feces. Lithium is filtered by the glomeruli and 80% of the filtered lithium is reabsorbed in the tubules, probably by the same mechanism responsible for sodium reabsorption. The renal clearance of lithium is proportional to its plasma concentration. Webcreases the risk of lithium toxicity.68 As lithium is renally cleared, diuretic medications may affect lithium levels. Thi-azide diuretics trigger an increase in reabsorption in the proximal tubule and can elevate lithium levels, whereas loop diuretics do not promote lithium reabsorption and do not generally affect lithium levels.69 Osmotic ... dewittbank.com
