Benefits
- Definitive treatment for central diabetes insipidus — replaces deficient ADH and normalizes urine output and thirst in >95% of patientsstrong
- Reduces bedwetting episodes in primary nocturnal enuresis — effective in 60-70% of children, with 25-30% achieving full drynessstrong
- Hemostatic agent for type 1 von Willebrand disease — raises vWF and factor VIII levels 3-5 fold, controlling bleeding without blood productsstrong
- Treats mild hemophilia A (factor VIII >5%) — transiently raises factor VIII levels sufficient for minor surgical procedures and bleeding episodesstrong
- Reduces nocturia episodes in adults — Nocdurna/Noctiva sublingual formulations specifically approved for nocturia due to nocturnal polyuriastrong
Dosage Protocols
| Route | Dosage Range | Frequency | Notes |
|---|---|---|---|
| Intranasal spray (diabetes insipidus) | 10-40 mcg | 1-3 times daily, divided doses | DDAVP nasal spray delivers 10 mcg per spray. Adjust dose to control thirst and urine output. Fluid intake must be restricted to prevent hyponatremia. |
| Oral tablet (diabetes insipidus/nocturnal enuresis) | 0.1-0.4 mg | 2-3 times daily (DI); at bedtime (enuresis) | Oral bioavailability is ~5% but dose is adjusted accordingly. For enuresis, start 0.2 mg at bedtime and titrate to 0.6 mg. Restrict evening fluids. |
| Sublingual melt (Nocdurna) | 27.7 mcg (women) or 55.3 mcg (men) | Once daily, 1 hour before bedtime | Specifically approved for nocturia due to nocturnal polyuria. Gender-specific dosing. Contraindicated in patients at risk for hyponatremia; monitor sodium at 1 week and 1 month. |
| Intravenous or subcutaneous (hemostatic) | 0.3 mcg/kg | Single dose; may repeat once at 12-24 hours | For von Willebrand disease type 1 or mild hemophilia A. Infuse IV over 15-30 minutes. Check vWF/factor VIII response with test dose before relying on for surgery. Tachyphylaxis limits repeated dosing. |

Side Effects
- Hyponatremia — the most serious risk; water retention without adequate fluid restriction can cause dilutional hyponatremia, seizures, and cerebral edema, especially in children and elderlyserious
- Headache — the most common adverse effect, reported in 10-25% of patients across formulationscommon
- Nausea and abdominal pain — gastrointestinal complaints in 5-15% of patients, particularly with oral formulationscommon
- Nasal congestion, rhinitis, and epistaxis — with intranasal formulations, occurring in 3-10% of patientscommon
- Facial flushing — transient vasodilation particularly with IV desmopressin, seen in 5-10% of patientscommon
- Tachyphylaxis — reduced hemostatic response with repeated doses over 24-48 hours due to depletion of vWF/factor VIII storesrare
