DDAVP Nasal Spray: Uses, Dosage, Side Effects, Precautions and Alternates

Quick overview

DDAVP Nasal Spray contains desmopressin acetate, a synthetic form of the hormone vasopressin, given as a spray into the nose. It is used to manage central diabetes insipidus, including excessive urine production and excessive thirst caused by vasopressin deficiency. The spray works by helping the kidneys hold on to water, reducing urine output and supporting normal fluid balance. It should be used exactly as directed, with fluid intake limited as advised by a doctor to avoid low sodium levels.

How DDAVP Nasal Spray works

Desmopressin is a man-made version of the natural hormone vasopressin. It acts on the kidneys to make them hold onto more water, which cuts down the amount of urine the body makes.

DDAVP Nasal Spray dosage

This spray does not work like typical cold or allergy nasal sprays — it should not be sniffed, because it only works when absorbed inside the nose. Gently blow your nose before using the spray if it feels blocked, since congestion can reduce how well the medicine is absorbed. Do not shake the bottle before use. The spray pump must be primed before first use by pressing down several times, and the bottle should be kept upright when spraying so the tube draws from the bottom of the liquid.

Replace the cap after each use. If you haven't used the spray for about a week, re-prime it before your next dose. Children should only use this spray under adult supervision to make sure the right amount is given.

If you miss a dose, take it as soon as you remember, but if it is almost time for your next dose, skip the missed one and go back to your normal schedule — do not double up. Limit the amount of fluids you drink while using this medicine, as directed by your doctor, to reduce the risk of low sodium levels. Older adults and young children should be watched closely for signs of drinking too much fluid.

Warnings and precautions

• This medicine can cause your body to retain too much water, which lowers your blood sodium to dangerous levels. This can cause seizures, coma, or even death if not treated. Your doctor may have you limit fluids you drink.
• This spray is only meant to be used in the nose and should not be swallowed or used any other way.
• Children and elderly patients are at higher risk of water retention and low sodium levels, so fluid intake needs to be carefully controlled in these groups.
• Do not use this medicine if you have ever had low blood sodium levels or certain heart, kidney, or fluid-balance conditions.
• Severe allergic reactions, though rare, have happened with this medicine and can include swelling of the face, mouth, or throat and trouble breathing.
• Changes in the lining of your nose from colds, scarring, or swelling may cause the medicine to be absorbed unevenly, making it less reliable.
• There are no well-controlled studies of this medicine in pregnant women. Animal studies did not show harm to the fetus, but you should discuss the benefits and risks with your doctor if you are or might be pregnant.
• Small amounts of the medicine may pass into breast milk. There have been no controlled studies in nursing mothers, so caution is advised if you are breastfeeding.
• This medicine should not be used if you have moderate to severe kidney problems, since the drug is removed from the body mainly through the kidneys and may build up and increase side effects.

When to see a doctor

• Get emergency help right away if you have signs of a serious allergic reaction, such as hives, difficulty breathing, or swelling of your face, lips, tongue, or throat.

• Seek medical help if you gain weight rapidly or notice swelling in your feet or ankles.
• Get medical attention right away if you have a seizure.
• If you suspect you've taken too much of this medicine, contact your doctor or emergency services right away, as overdose can cause headache, confusion, drowsiness, and dangerous fluid retention.
