Complete patient guide for uses, dosage, side effects, and safety information
Quick Facts
What Is Minirin Injection Used For?
Minirin Injection is a synthetic form of vasopressin, a hormone that helps regulate water balance in the body. It is used to treat various conditions related to fluid regulation and bleeding disorders.
Primary Uses
Minirin Injection is primarily used for treating cranial diabetes insipidus, conducting diagnostic tests for kidney function in adults, increasing blood clotting factor VIII in patients with mild to moderate hemophilia A and von Willebrand's disease (excluding type IIB), and managing excessive bleeding in patients with certain platelet defects.
How It Works
Minirin Injection works by mimicking the action of vasopressin, which reduces urine production and helps the kidneys concentrate urine.
Good to know: Minirin Injection is not addictive.
