Prescribing Notes

  • A single dose of desmopressin is also used as part of a test following fluid deprivation in the differential diagnosis of thirst and polyuria.
  • For nephrogenic diabetes insipidus, the usual treatment is a thiazide diuretic. Caution if due to lithium – refer to endocrinologist.
  • Desmopressin injection (4 micrograms/mL) may be indicated in unconscious patients (dose 1-4 micrograms daily by subcutaneous, intramuscular or intravenous injection).
  • Measurement of plasma sodium should be undertaken to guard against excessive water intake which would be reflected by a low plasma sodium. The frequency of monitoring should be individualised and more frequent monitoring will be required during the stabilisation phase.
