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.
The medication used to treat this disorder is called desmopressin acetate (DDAVP), which is similar to the hormone antidiuretic hormone (ADH), also called vasopressin, produced by your body. DDAVP comes in several forms. Your doctor will work with you to prescribe the one that works best for you.
