Most cases of hyponatremia that occur out of the hospital are chronic and minimally symptomatic, except in marathon runners, users of 3,4-methylenedioxymethamphetamine MDMA, also known as “ecstasy”and people who drink water to excess; in these groups, severe symptoms usually indicate acute hyponatremia and require rapid correction. Am Heart J ; Hyonatremia formulas incorporate amounts of salt and hgponatremia infused and excreted 3940 ; these add precision, but at the price of complexity.

Successful long-term treatment of hyponatremia in syndrome of inappropriate antidiuretic hormone secretion with SR B, an orally active, nonpeptide, vasopressin V-2 receptor antagonist. Am J Med Sci ; SSRIs, anti-seizure medications, sulfonylureas, opioid narcotics Urine sodium is low in volume depletion, heart failure, and cirrhosis. The rate of change in serum sodium levels must be monitored every 2 to 3 hours, and the infusion adjusted as needed. Hypovolemia trumps plasma osmolality.

Use of these agents in practice would require similarly close monitoring of serum sodium levels. Step up your salt game.
