What is desmopressin?
Desmopressin acetate is a synthetic drug that is a copy of a natural hormone. It acts by releasing von Willebrand factor stored in the lining of the blood vessels. Two brands of desmopressin acetate are Stimate® Nasal Spray, which is a high-concentration nasal spray, and DDAVP®, which comes in an injectable form. NOTE: Stimate® Nasal Spray is a high-concentration nasal spray. A low-concentration nasal spray is also available, but is used to treat diabetes insipidus and bed-wetting. The low-concentration nasal spray is NOT effective in treating VWD. People with VWD should only receive the high concentration form of desmopressin.1 Be sure to ask for Stimate® Nasal Spray by name.
