Ectopic ADH secretion

  • Alternative Names

    SIADH; Syndrome of inappropriate antidiuretic hormone secretion


    Treatment is aimed at removing the cause of the problem (for example, surgery to remove a tumor producing ADH).

    Limiting fluid intake is another common treatment. This helps prevent excess water from building up in the body.

    Patients in the hospital with ectopic ADH that does not respond to other treatments may be given tolvaptan by mouth (orally) and conivaptan through a vein (intravenous). These treatments block the effects of ADH.
