Hyponatremia in association with second-generation antipsychotics: a systematic review of case reports

Background: Hyponatremia is generally defined as a serum sodium level = 60 years. The average patient age was 47 years, and the average time to the hyponatremia event was 17 days. The average serum sodium was 138 mmol/L at baseline, 112 mmol/L at treatment nadir, and 138 mmol/L after treatment discontinuation.Conclusion: Hyponatremia can result from the use of SGAs in patients with schizophrenia and can be avoided with proper management of treatment. Physicians, psychiatrists, and other healthcare workers should be aware of the potential for severe hyponatremia with the use of commonly prescribed SGAs. SGA-induced hyponatremia is generally reversible after discontinuing treatment
