Replaces the missing hormone; the standard treatment since the 1970s. Older trials, not modern RCTs, but the effect is unambiguous.

In context

Desmopressin is a synthetic analogue of the antidiuretic hormone vasopressin that concentrates urine without raising blood pressure. It is approved for diabetes insipidus, bedwetting, nocturia and some bleeding disorders. A Cochrane review of 14 trials found it reduces night-time voids by a little under one per night in men. Its serious risk is hyponatraemia — low blood sodium — in about 7.6% of older adults, which is why sodium is monitored. It is on WADA's list as a masking agent.

Desmopressin is approved (rx). Legal status differs by country — see the regulation section or the jurisdiction pages.
