What is desmopressin?
Desmopressin is a lab-modified version of vasopressin, a natural hormone. The Czech chemist Miroslav Zaoral engineered it in the 1960s to last longer and lose vasopressin's blood-pressure-raising effect, while keeping its effects on water retention and clotting. It was first approved in the late 1970s as DDAVP for central diabetes insipidus, and later for bedwetting and two bleeding disorders.
Does desmopressin work?
The FDA reviewed the trials and approved it for central diabetes insipidus, bedwetting and bleeding disorders. Most of the rigorous efficacy trials behind those uses are decades old.
What we found. 8+ completed randomized trials counted on the record. 3 study rows listed below, and each stands for a group of studies, so the number shows with a plus sign until every trial is listed.
| Study | Tested in | Status | What it shows |
|---|---|---|---|
| Original registration studies in central diabetes insipidus | People | Completed. Approved in the 1970s | Early clinical studies showed an antidiuretic, or water-retaining, effect in central diabetes insipidus |
| Clotting studies in hemophilia A and von Willebrand disease | People | Completed. Approved | Trials showed a temporary rise in factor VIII and von Willebrand factor, two clotting factors |
| Bedwetting (nocturnal enuresis) trials | People | Completed. Approved | Randomized trials in children showed fewer bedwetting episodes than placebo |
Is desmopressin safe?
The main safety concern on the record is water retention. It can lead to dangerously low sodium levels when fluid intake is not managed, especially in older people. The record says large updated trials in night-time urination problems, with modern safety monitoring, would strengthen the evidence for newer versions of the medicine. What is known here describes the prescription medicine. A vial from outside that system is the next subject.
Is desmopressin legal?
- United States
- Approved by the FDA as DDAVP since the late 1970s, first for central diabetes insipidus. Later approvals added bedwetting and two bleeding disorders, mild hemophilia A and von Willebrand disease.
- European Union
- Approved by the EMA. The record says only "equivalent indications".
- Sport
- Banned in sport at all times. WADA's 2026 Prohibited List names desmopressin in class S5, diuretics and masking agents.

What is in a vial sold as desmopressin?
The record describes desmopressin as a routine prescription medicine that specialists have used for decades. It holds no sign of desmopressin sold outside pharmacies. If a vial reached you another way, the studies on this page did not test it, and the checklist lists what to ask the seller.
What don't we know?
- What modern trials would show. Most of the rigorous efficacy trials are decades old.
- Whether it does better or worse than the alternatives in some of its uses. Newer comparison data are weaker.
- What is in any vial that did not come from a pharmacy.
The other side
Desmopressin comes with a prescription and a doctor's care. The record calls it a routine medicine that several kinds of specialists have used for decades. The gap on this page is about how old the trials are.
What would change this record?
- Large, updated randomized trials in nocturia or nocturnal polyuria, two night-time urination problems, with modern safety monitoring. The record says they would strengthen the evidence for newer versions of the medicine.
Change log
