- that the use of the medicine in children is supervised by an adult controlling the dose taken.
Additionally, regarding the test of the ability of the kidneys to concentrate urine
The test of the ability of the kidneys to concentrate urine in children under 1 year of age should only be performed in a hospital under close medical supervision.
During the test of the ability of the kidneys to concentrate urine, fluid intake should be restricted to a maximum of 0.5 liters from 1 hour before administration to 8 hours after administration.

Children, the elderly, and patients with sodium levels in the blood at the lower limit of normal are at greater risk of developing hyponatremia.
To avoid hyponatremia, special precautions should be taken, including careful monitoring of fluid intake and more frequent measurement of sodium levels in the blood, especially when using medicines that can cause the syndrome of inappropriate antidiuretic hormone secretion (SIADH), such as tricyclic antidepressants, selective serotonin reuptake inhibitors, chlorpromazine, carbamazepine, oral hypoglycemic agents of the sulfonylurea group, especially chlorpropamide, and non-steroidal anti-inflammatory drugs.
In case of acute conditions with water and electrolyte disturbances, such as generalized infection, diseases with fever, gastroenteritis, a doctor should be consulted.
There is evidence, obtained after the marketing of this medicine, of cases of severe hyponatremia associated with the use of desmopressin nasal spray for the treatment of central diabetes insipidus.
