What the studies show
Reduces wet nights during treatment; relapse on stopping is common, and alarm training has more durable effect.
Several well-run randomised trials in people, pointing the same way. You can plan around this. It still says nothing about whether the effect is worth the side effects for you.

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.
