Uses of This Medicine:

Desmopressin 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 bedwetting (nocturnal enuresis), and the 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.

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

Before Using This Medicine:

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.

Children—

Appropriate studies performed to date have not demonstrated pediatric-specific problems that would limit the usefulness of desmopressin in children. However, safety and efficacy have not been established for diabetes insipidus in children younger than 4 years of age, and for bedwetting in children younger than 6 years of age.

Older adults—

Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of desmopressin 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.

Breast-feeding—

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.
