Uses For Minirin

Desmopressin nasal spray is used to treat central cranial diabetes insipidus. This is a condition that causes the body to lose too much fluid and become dehydrated. It is also used to control frequent urination and increased thirst caused by certain types of brain injury or brain surgery. The Stimate® nasal spray is used to treat bleeding in patients with hemophilia A or von Willebrand disease (Type I).

Desmopressin is similar to a hormone that is produced in the body. It acts on the kidneys to reduce the flow of urine. For bleeding, desmopressin increases the blood levels of factor VIII and von Willebrand factor. This results in less bleeding for patients who have low levels of these agents.

This medicine is available only with your doctor's prescription.

Before Using Minirin
