- 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).
