FAQ
Common questions about desmopressin
Below you’ll find answers to a few commonly asked questions about desmopressin.
What is desmopressin’s mechanism of action? And how does the drug work?
Desmopressin is a human-made form of a hormone in your body called antidiuretic hormone (ADH). When you don’t have enough ADH in your body, it will cause excess urination. Desmopressin works by replenishing ADH in your body. This lowers the amount of urine your body makes by increasing the amount of water that’s reabsorbed in your kidneys. To treat bleeding disorders, desmopressin works by increasing the level of a protein in your blood that helps you stop bleeding.
Desmopressin nasal spray starts working within 30 minutes. Desmopressin oral tablet starts working about 1 hour after you take your dose. Desmopressin injection starts working within 30 minutes after it’s given.
If you’d like to know more about this, talk with your doctor or pharmacist.
Is desmopressin safe for older adults?
Maybe. Older adults (age 65 years and older) may not clear desmopressin from their bodies as easily as younger adults. This can cause the medication to build up in the body and increase the risk of side effects. Due to this risk, doctors may prescribe desmopressin at a dosage that’s on the low end of the recommended range for older adults.
Also, older adults should pay special attention to their fluid intake while taking desmopressin. Drinking too much fluid may raise the risk of low sodium levels in your blood. Your doctor will discuss with you how much fluid you can drink while taking this drug.
If you have concerns about taking desmopressin given your age, talk with your doctor.
Uses
Uses of desmopressin
The Food and Drug Administration (FDA) approves prescription drugs such as desmopressin for certain conditions. Approved uses for desmopressin are described below. These uses differ based on the form of desmopressin prescribed.
Use for diabetes insipidus
Doctors may prescribe desmopressin nasal spray, oral tablet, and injection for treating central diabetes insipidus. Desmopressin nasal spray and oral tablet are used for this purpose in children ages 4 years and older and adults. Desmopressin injection as a subcutaneous injection (injection under your skin) or an intravenous (IV) injection (injection given into a vein) is used for this purpose in children ages 12 years and older and adults. It’s usually prescribed as a long-term treatment.
Diabetes insipidus is a condition where your kidneys cannot conserve water. This results in extreme thirst and frequent urination. There are different types of diabetes insipidus. Desmopressin is approved to treat central diabetes insipidus, which is caused by damage to certain parts of the brain. This damage causes irregular amounts of antidiuretic hormone (ADH) to be made, stored, or released. Low levels of ADH cause large amounts of fluid to be released in your urine. Desmopressin treats central diabetes insipidus by replenishing ADH in your body.
Doctors may not prescribe desmopressin nasal spray in certain situations, such as for:
- nephrogenic diabetes insipidus (rare disorder in which your kidneys can’t concentrate your urine)
- nighttime bedwetting
- people with conditions that make it difficult to use nasal sprays, such as severe nasal congestion
- people with decreased consciousness
- people who require unique dosages of desmopressin
Doctors may not prescribe desmopressin injection in certain situations, such as for nephrogenic diabetes insipidus.
Use for nighttime bedwetting
Doctors may prescribe desmopressin oral tablet to help prevent nighttime bedwetting. It’s used for this purpose in children ages 6 years and older and adults. It’s usually prescribed for up to 6 months.
Nighttime bedwetting occurs when there’s a loss of bladder control during the night. One of the causes of bedwetting is hormonal imbalances. ADH is a hormone that tells your body to slow down the production of urine overnight. People who don’t make enough ADH can have nighttime bedwetting. Desmopressin treats bedwetting by replenishing ADH in your body.
It’s important to note that desmopressin nasal spray is not approved for nighttime bedwetting.
Use for certain bleeding disorders
Doctors may prescribe desmopressin injection for treating hemophilia A and von Willebrand disease (Type I). It’s given as an intravenous (IV) infusion (an injection into your vein given over time) for this purpose in adults and children ages 3 months and older. It’s usually prescribed as a long-term treatment.
Bleeding occurs when your blood vessel is damaged. When this happens, small cells called platelets form a plug at the injury site. Then, small proteins called clotting factors are turned on to help the platelets stick to the opening. This forms a sticky plug that stops blood from flowing out. Desmopressin treats bleeding disorders by increasing the levels of a specific clotting factor called factor VIII.
Doctors may not prescribe desmopressin injection in certain situations, such as for treatment of severe type I von Willebrand disease or if you have certain abnormal results on a factor VIII blood test.
Interactions and warnings
Interactions and warnings for desmopressin
Below, you’ll find information about desmopressin’s possible interactions and warnings.
Interactions of desmopressin
Certain things may affect how a drug works. These include getting vaccines, consuming alcohol or certain foods, or taking the drug with other medications. This effect is called a drug interaction.
Before you use desmopressin, ask your doctor to check for possible interactions. Be sure to tell them about any of the following you take or use:
- prescription or over-the-counter drugs
- vitamins, herbs, or supplements
To learn about drug-condition interactions, see the “Warnings for desmopressin” section below.
Warnings for desmopressin
Some people should not use desmopressin, and others should use it cautiously.
Boxed warning: Risk of low sodium levels
Desmopressin injection has a boxed warning about the risk of hyponatremia (low sodium levels in the blood). Boxed warnings are the most serious warnings from the Food and Drug Administration (FDA).
Sodium is an electrolyte that helps maintain the balance of water in and around your cells. It also plays a role in muscle and nerve function, and it helps maintain blood pressure levels. Having too little sodium in your blood can be dangerous and life threatening if it’s not diagnosed and treated. It can lead to seizures, coma, stopped breathing, or death. Because of this risk, your doctor will not prescribe desmopressin injection if you have health conditions or take medications that affect your sodium and water balance.
Your doctor will order tests to check your sodium levels before and during treatment with desmopressin.
If you experience any symptoms of hyponatremia, such as weakness, fatigue, muscle cramps, confusion, or overactive reflexes, tell your doctor. They’ll likely order tests to check your sodium levels. And if your levels are low, your doctor may recommend stopping desmopressin either temporarily or permanently.
To learn more, talk with your doctor or pharmacist.
Other warnings
Desmopressin could cause harm to people with certain health conditions. This effect is called a drug-condition interaction. Other factors can also affect whether desmopressin is a safe option for you. These warnings may differ based on the form of desmopressin you use or take.
Ask your doctor about specific warnings for desmopressin, and be sure to tell your doctor about your:
- current health, including any allergies to medications
- past health conditions or surgeries

If you’ve had an allergic reaction to desmopressin or any of its ingredients, your doctor will likely not prescribe desmopressin. They can tell you about medications that are safer options for you.
A mild allergic reaction may cause the following symptoms:
A severe allergic reaction may cause the following symptoms:
- swelling under your skin, usually in your hands, feet, eyelids, or lips

If you have an allergic reaction to desmopressin, call your doctor right away. If you have severe symptoms, call 911 or a local emergency number.
