Desmopressin promotes water retention and can cause water intoxication and hyponatremia. Daily weight and intake-output monitoring help identify excess fluid retention, while headache, nausea, confusion, or sudden weight gain should be reported promptly. Forcing large amounts of fluid can increase the risk. Symptom improvement does not mean endogenous antidiuretic hormone production has recovered, and persistent very high urine output suggests inadequate control rather than effectiveness.
In-depth explanation
Clinical reasoning summary
Desmopressin can cause excessive water retention and hyponatremia. Teach daily weight and intake-output monitoring and prompt reporting of headache, nausea, confusion, or sudden weight gain. Do not stop the medication or force fluids without provider guidance.
