Minirin is used as an effective way to reduce nocturnal enuresis in children and adults, especially if the problem is caused by increased urine production at night. It is a primary treatment for this type of diabetes insipidus, as it helps compensate for a deficiency in the hormone vasopressin that results from problems with the pituitary gland or hypothalamus. In some cases, Minirin can be used to enhance the secretion of blood clotting factors in people with factor VIII deficiency or mild to moderate von Willebrand disease.
Minirin can also be used as part of medical tests to determine the kidneys' ability to concentrate urine, which helps doctors diagnose certain medical conditions.
