Aggressive treatment of hyponatremia should always be weighed against the risk of inducing CMP. A rare but serious complication, CMP can develop 1 to several days after aggressive treatment of hyponatremia. Aggressive management of hyponatremia is indicated in patients with severe symptoms such as seizures, stupor, coma, and respiratory arrest, regardless of the degree of hyponatremia. Emergent treatment should also be strongly considered for those with moderate-to-severe hyponatremia with a documented duration of less than 48 hours.
