text: If the person's lithium toxicity is mild or moderate, lithium dosage is reduced or stopped entirely. If the toxicity is severe, lithium may need to be removed from the body. The removal of lithium is done in a hospital emergency department. It may involve:
  *Gastric lavage. A tube is placed through the nose or mouth into the stomach. The tube is used to remove lithium that has not been digested yet. It may also be used to put medicines directly into the stomach to help stop lithium from being absorbed.
  *Use of an artificial kidney to clean the blood (dialysis). This is usually done only in the most severe cases.
  *Diuretic medications such as furosemide and hydration via intravenous normal saline appear to be effective in speeding the removal of lithium and also rehydrate patients who've lost fluids.
  *Hemodialysis. Hemodialysis is widely advocated as a means of reducing the risk of permanent neurological sequelae following lithium poisoning. Although hemodialysis clearly enhances the elimination of lithium, it is unclear whether this translates into improved patient outcomes.
  People may be sent home once their blood serum lithium level is less than 1.5 mEq/L and they have no symptoms.
