Lithium has been commonly used for the treatment of several mood disorders particularly bipolar disorder in the last 60 years. This study aimed to analyze patients with lithium intoxication referred to Loghman- Hakim teaching hospital. This is a cross sectional study that has been done on 108 patients with lithium intoxication during 2001 to 2010. Necessary data were collected by checklists and then analyzed by statistical methods in SPSS version 20. 39.8% of patients were male and most of them were in age group 20-40 years (47.2%). The rate of lithium use in 66.7% of patients was lower than 20 grams and the level of lithium in blood was 1 mEq/lit in 44.4% of patients. The rate of recovery has been significantly relation with BUN, creatinin, Intubation, pCO2 and pH. There was a significant relation between hospitalized with pH, pCO2, Na, absorbent materials, intubation and bicarbonate. Results showed that we should note to the rate and time of lithium used and also severity of signs in management and treatment of patients with the lithium toxicity.
