Desmopressin


Desmopressin is used to control the symptoms of a certain type of diabetes insipidus ('water diabetes'; condition in which the body produces an abnormally large amount of urine). Desmopressin is also used to control excessive thirst and the passage of an abnormally large amount of urine that may occur after a head injury or after certain types of surgery. Desmopressin is also used to control bed-wetting. Desmopressin is in a class of medications called hormones. It works by replacing vasopressin, a hormone that is normally produced in the body to help balance the amount of water and salt.
