Which of the following is part of the management of antidiuretic hormone dysfunction?

• A. Fluid restriction, demeclocycline (1200 mg/day), captopril (12.5 mg/day), propranolol (30-120 mg/day), correct electrolytes
• B. Fluid excess and hydration
• C. Desmopressin therapy
• D. Observation only

Answer: (A)

Managing antidiuretic hormone dysfunction depends on the specific disorder, with SIADH being a common focus. In SIADH, excessive ADH causes water retention and dilutional hyponatremia, so treatment aims to reduce water excess and counter the ADH effect. Fluid restriction limits further water retention and helps correct the sodium imbalance. Demeclocycline works by blunting the kidney’s response to ADH, promoting free water excretion and helping to resolve hyponatremia when fluid restriction alone isn’t enough. Correcting electrolytes is essential because hyponatremia and related imbalances drive symptoms and require careful management to avoid rapid shifts that can harm the brain. Desmopressin would worsen hyponatremia by increasing ADH activity, so it’s not used in SIADH. Fluid excess or hydration would continue to worsen the hyponatremia, and observation alone would not treat the underlying issue.
