For patients with normovolemic (euvolemic), asymptomatic hyponatremia, free water restriction (< 1 L/d) is generally the treatment of choice. When treating patients with overtly symptomatic hyponatremia (eg, seizures, severe neurological deficits), hypertonic (3%) saline should be used. Pharmacologic agents can be used in some cases of more refractory SIADH, allowing more liberal fluid intake. Demeclocycline has been the drug of choice to increase the diluting capacity of the kidneys by achieving vasopressin antagonism and functional diabetes insipidus.
