Desmopressin Reference

Plain English

What it is

Desmopressin (brand names DDAVP and Stimate) is an FDA-approved prescription medicine. It is a man-made copy of vasopressin, a natural body hormone that helps the kidneys hold on to water.

What people use it for

Doctors prescribe it for central diabetes insipidus, a condition that causes very heavy urination and thirst. It is also approved for bedwetting in children (called primary nocturnal enuresis) and to help control bleeding in certain bleeding disorders, including hemophilia A and mild to moderate von Willebrand disease.

What the science shows

It is backed by decades of approved-label evidence in people, so its uses and risks are well documented. pepSmart shows label-reference information for it only. It is a prescription medicine, not a research peptide.

The catch

Because it makes the body keep water, it can cause low blood sodium (called hyponatremia) and water intoxication, which the label says can be fatal if it is not found and treated, with severe cases leading to seizures, coma, or trouble breathing. The label stresses limiting fluid intake to lower this risk, which matters most in older adults and young children. It is a different drug from plain vasopressin.
