Desmopressin nasal spray used for nocturnal enuresis carries which safety warning?

• A. No safety warnings apply
• B. Hyponatremia risk is managed with caution
• C. Black box warning for hyponatremia
• D. Desmopressin nasal spray is never recommended

Answer: (C)

Desmopressin nasal spray for nocturnal enuresis carries a black box warning for hyponatremia, a potentially dangerous drop in blood sodium. The medicine works by mimicking vasopressin to reduce urine production, but this antidiuretic effect can lead to water retention. If fluid intake isn’t limited after taking the dose, serum sodium can fall, which in children can cause headaches, confusion, seizures, or other serious problems. That’s why this warning is emphasized: it signals the highest level of safety concern and the need for strict dosing and fluid-management instructions, along with education for caregivers about recognizing symptoms of hyponatremia and seeking urgent care if they occur. In contrast, claims that no safety warnings exist or that this warning is unnecessary are incorrect, and saying the medication is never recommended ignores appropriate, monitored use with proper precautions.
