Desmopressin, sold under the trade name DDAVP among others, is a medication used to treat diabetes insipidus, bedwetting, hemophilia A, von Willebrand disease, and high blood urea levels. In hemophilia A and von Willebrand disease, it should only be used for mild to moderate cases.
Desmopressin is used in several different conditions. It is a vasopressin analogue, which means that it is similar to a naturally occurring hormone called vasopressin. Vasopressin is also called antidiuretic hormone (ADH). ADH has an effect on your kidneys. It causes your kidneys to pass out less water in your urine, so your urine becomes more concentrated.
