What Desmopressin Spray is and what it is used for
Desmopressin Spray contains the active ingredient desmopressin which belongs to a group of medicines called “posterior pituitary lobe hormones, vasopressin and analogues”. Desmopressin is very similar to a natural hormone in the body which can reduce the amount of urine that the body produces.
Desmopressin Spray is used to treat diabetes insipidus; this is a condition which causes extreme thirst and the production of large volumes of dilute urine.
Desmopressin Spray can also be used to test how well your kidneys are working.

How to take Desmopressin Spray
Desmopressin Spray should only be used by the nasal route.
Always take Desmopressin Spray exactly as your doctor has told you. Check with your doctor or pharmacist if you are not sure. The recommended doses are given below.
Treatment of diabetes insipidus
Adults: 1 or 2 sprays each day (2 sprays should be given as one spray into each nostril).
Children and Adolescents below 18 years: 1 spray each day.
Your doctor may increase the dose to 4 sprays each day (taken as one spray into each nostril, in the morning and at bedtime).
To test how well your kidneys are working:
The dosage will depend on your weight and will vary from 1 to 4 sprays.
Before using the spray, you will be asked to empty your bladder. Samples of your urine will then be taken at regular intervals after you have used the spray. Your fluid intake will also be restricted during the first 12 hours after using the spray.
Instructions for use:
Before using Desmopressin Spray for the first time, you must prime the nozzle (i.e. fill it with the medicine). To do this remove the protective cap. Then hold the bottle upright (Figure 1) and pump the nozzle up and down 3 times, spraying into the air until an even mist is seen. Desmopressin Spray is now ready to use.
-
1. Blow your nose. Remove the protective cap.
-
2. Hold the bottle as shown in Figure 2.
-
3. Tilt your head back and insert the tip of the nozzle into your nostril, as shown. Spray into the nostril while breathing in slightly. When pressing the pump down, ensure that you apply even pressure and press down quickly to produce a consistent spray.
-
4. If necessary, spray into the other nostril in the same way.
-
5. Wipe the nozzle with a clean tissue and replace the protective cap. Store the bottle in an upright position.
If the spray is not used within 7 days of the previous dose, reprime by pressing the nozzle at least once before using.
Ensure that the dip-tube is in the liquid when using Desmopressin Spray. Hold the bottle as upright as possible when using (see figure 2).
Make sure you do not run out of Desmopressin Spray
The nasal spray has been designed to deliver 60 sprays of your medicine. However, it has also been designed to contain a ‘fill overage’ so there will always be a small amount of fluid left over in the bottle which it is not possible to use. Please make sure that your nasal spray is replaced in advance of you taking 60 sprays and within 4 weeks of first opening/using the product so that you can be certain that you will not run out of medicine, especially if you have to re-prime the spray between uses.
If you take more Desmopressin Spray than you should
Talk to your doctor or pharmacist straight away and also reduce your fluid intake. An overdose of this medicine can lead to headache, nausea (feeling sick), tummy cramps, and in severe cases it can cause fits.
If you forget to take Desmopressin Spray
Do not worry. Simply leave out that dose completely and then take your next dose at the right time. Do not take a double dose to make up for a forgotten dose.
If you stop taking Desmopressin Spray
The symptoms may return that you had before starting treatment.
