Description
Desmopressin injection is used to treat bleeding in patients with hemophilia A or von Willebrand disease (Type I). It is also used to treat central cranial diabetes insipidus. This is a condition that causes the body to lose too much fluid and become dehydrated. Desmopressin injection is used to control frequent urination and increased thirst caused by certain types of brain injury or brain surgery.
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.
This product is available in the following dosage forms:
- Solution
Before Using
In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For this medicine, the following should be considered:
Allergies
Tell your doctor if you have ever had any unusual or allergic reaction to this medicine or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.
Pediatric
Appropriate studies performed to date have not demonstrated pediatric-specific problems that would limit the usefulness of desmopressin injection in children. However, the safety and efficacy of desmopressin injection have not been established for children younger than 12 years of age with diabetes insipidus, and for children younger than 3 months of age with hemophilia A or von Willebrand disease.
Geriatric
Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of desmopressin injection in the elderly. However, elderly patients are more likely to have age-related kidney problems, which may require caution and an adjustment in the dose for patients receiving desmopressin.

There are no adequate studies in women for determining infant risk when using this medication during breastfeeding. Weigh the potential benefits against the potential risks before taking this medication while breastfeeding.
