desmopressin nasal solution

How does this medication work? What will it do for me?

Desmopressin nasal solution belongs to 2 classes of medications: antidiuretics and antihemorrhagics. It can be used to treat central diabetes insipidus, a condition where the kidneys are unable to conserve water due to a lack of antidiuretic hormone (ADH). This condition causes frequent urination and thirst. It is also used to treat temporary increased thirst and urination that can occur after a head injury or certain types of brain surgery. For these uses, desmopressin nasal solution works by helping to reduce the amount of urine produced by the kidneys.

Desmopressin nasal solution may also be used to prevent bleeding for people with mild hemophilia A and mild von Willebrand's disease type I. Desmopressin nasal solution works by increasing certain components involved in blood clotting.

This medication may be available under multiple brand names and/or in several different forms. Any specific brand name of this medication may not be available in all of the forms or approved for all of the conditions discussed here. As well, some forms of this medication may not be used for all of the conditions discussed here.

Your doctor may have suggested this medication for conditions other than those listed in these drug information articles. If you have not discussed this with your doctor or are not sure why you are being given this medication, speak to your doctor. Do not stop using this medication without consulting your doctor.

Do not give this medication to anyone else, even if they have the same symptoms as you do. It can be harmful for people to use this medication if their doctor has not prescribed it.

Are there any other precautions or warnings for this medication?

Before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.

Cystic fibrosis (CF): People with cystic fibrosis are susceptible to decreased levels of sodium in the body. Changes in fluids and electrolytes caused by desmopressin may cause worsening symptoms of CF. If you have CF, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.

Effectiveness: Desmopressin is not effective in controlling excessive urination caused by kidney disease, psychiatric conditions, low blood potassium, or high blood calcium.

Fluid and electrolyte balance: Fluid intake should be adjusted in order to reduce the possibility of water retention and low levels of sodium in the blood, especially in children and seniors. Talk to your doctor about how much fluid intake is appropriate for you or your child. People who are taking this medication should be closely monitored by their doctor. Stop taking this medication and get medical attention if you have symptoms of low sodium in the blood such as headache, nausea, or vomiting.

People who are dehydrated should wait until they are properly hydrated before taking desmopressin.

Heart failure: Imbalance in fluid and electrolytes can cause heart failure to worsen. If you have heart failure, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.

Kidney and liver function: People with decreased kidney or liver function are at an increased risk for electrolyte and fluid imbalance. Desmopressin further increases the risk of developing low levels of sodium in the body. If you have decreased kidney or liver function, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.

Nasal problems: People who have nasal conditions such as inflammation of the nose, scarring, or swelling may not completely absorb the medication. In these circumstances, the desmopressin nasal solution should not be used. Talk to your doctor about alternatives you can use.

Tolerance: There are reports of changes in response to the medication over time, usually when the medication has been used for longer than 6 months. Some people may experience decreased responsiveness, while others may experience a shortened duration of effect. If you notice this, contact your doctor.

Pregnancy: This medication should not be used during pregnancy unless the benefits outweigh the risks. If you become pregnant while taking this medication, contact your doctor.

Breast-feeding: It is not known if desmopressin nasal solution passes into breast milk. If you are a breast-feeding mother and are taking desmopressin nasal solution, it may affect your baby. Talk to your doctor about whether you should continue breast-feeding.

Children: The safety and effectiveness of using this medication have not been established for children younger than 3 months of age.

Seniors: People over the age of 65 years may be more sensitive to the effects of this medication.
