Description
Desmopressin is used to treat patients who awaken 2 or more times at night to urinate caused by nocturnal polyuria, a condition wherein your body makes too much urine at night. Your doctor may tell you to collect and measure your urine and the times that you urinate for 24 hours to determine if you have nocturnal polyuria.
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
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 have not been performed on the relationship of age to the effects of desmopressin in the pediatric population. Safety and efficacy have not been established.
Geriatric
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 hyponatremia (low sodium in the blood), which may require caution and an adjustment in the dose for patients receiving desmopressin.
