Lithium Toxicity
Also known as Lithium poisoning · Lithium toxicity · SILENT · Nephrogenic diabetes insipidus lithium · Whole bowel irrigation
The lithium toxicity — the narrow therapeutic index (the therapeutic 0.6 to 1.2 mmol/L), the renal clearance (the handled like the sodium), and the no antidote. The acute overdose (the early GI, the delayed neuro) versus the chronic toxicity (the neuro-dominant, the more dangerous — the tremor, the hyperreflexia, the ataxia, the seizures, the coma, the SILENT). The charcoal the not-bind; the whole-bowel irrigation for the sustained-release; the normal saline (the restore the GFR, the NOT the diuretics); the haemodialysis for the severe (with the rebound).

Overview & definition
Lithium is a commonly prescribed mood stabiliser for bipolar disorder, with a narrow therapeutic index: maintenance concentrations of 0.6 to 0.8 mmol/L are generally accepted, and some authorities still favour 0.8 to 1.2 mmol/L.[4] It is excreted almost exclusively by the kidney as the free ion, so kidney function governs the risk of toxicity — impaired renal function from volume depletion, intercurrent illness, and drug interactions that reduce lithium clearance all precipitate poisoning.[1] There is no antidote. Toxicity is neuro-dominant — the central nervous system is the primary site of toxicity — and lithium is readily dialyzable.[1]
