'Dos and don'ts' in the management of hyponatremia.

Abstract

The management of hyponatremia has evolved in recent years, particularly with the introduction of tolvaptan for hyponatremia secondary to the syndrome of inappropriate antidiuretic hormone secretion (SIADH). This commentary presents a summary of recent international recommendations in the form of a series of didactic 'dos and don'ts', in order to provide concise, practical guidance for practising clinicians focused on the investigation and management of euvolemic hyponatremia (SIADH).
