Patients with inadequate antidiuretic hormone secretion (SIADH) are prone to hyponatremia. Tolvaptan is indicated in adults for the treatment of hyponatremia secondary to SIADH. However, urea is proposed as a good therapeutic option for increasing sodium levels. In this document we report the case of a patient with hyponatremia associated with SIAH who is treated with tolvaptan, achieving a highly variable plasma sodium concentration. It seems that urea can contribute to a better control of sodium levels with a slower, progressive and stable rise, providing greater safety to our patient and also achieving cost reduction.
