Treatment of syndrome of<unk><unk><unk>  (SIADH) depends on the etiology. For immediate improvement, all patients with syndrome of<unk><unk><unk>  (SIADH) require strict restriction of their daily water intake and correction of serum sodium levels. The serum sodium can be corrected depending on the initial sodium levels of the patient. Mild cases can be managed easily with exclusive fluid restriction. Moderate cases of SIADH are treated with loop diuretics and normal saline; whereas, 3% hypertonic saline may be used in severe cases. In emergency settings, vasopressin-2 receptor antagonists (conivaptan or tolvaptan) are used. The definitive treatment of SIADH involves treatment of the underlying condition. Urea, demeclocycline, and lithium are also used in the treatment of SIADH.
