What Desmopressin is and what it is used for
The ingredient that makes the spray work (the active substance) is called desmopressin. Desmopressin is an antidiuretic, which reduces the amount of urine produced by the kidneys.
Desmopressin nasal spray is used to:
- treat and diagnose a chronic disease called diabetes insipidus which causes extreme thirst and continuous production of large volumes of dilute urine. Important: Not to be confused with diabetes mellitus (sugar diabetes)
- treat frequent urination during the night in adults (nocturia) associated with multiple sclerosis
investigate kidney function.
Before you use Desmopressin nasal spray
Do not use Desmopressin nasal spray if you:
- are allergic (hypersensitive) to desmopressin or any of the other ingredients in Desmopressin nasal spray (see section 6)
drink unusually large amounts of fluid (polydipsia)- suffer from heart problems, high blood pressure or other diseases needing treatment with diuretics (water tablets)
- are elderly (over the age of 65 years)
- suffer with alcohol abuse.
Check with your doctor or pharmacist before using Desmopressin nasal spray if you have:
kidney disease

Taking other medicines
Please tell your doctor or pharmacist if you are taking or have recently taken any other medicines, including medicines obtained without a prescription. Especially:
tricyclic antidepressants (used to treat depression e.g. amitriptyline or imipramine)
carbamazepine (used to treat epilepsy)
chlorpromazine (used to treat psychosis or schizophrenia)
indomethacin (painkillers called non-steroidal anti-inflammatory drugs (NSAIDs)).
Fluid intake
- Before you start treatment with this medicine, your doctor should give you advice about fluid intake.
- When using this medicine for nocturia or to investigate kidney function, keep your fluid intake to a minimum from 1 hour before a dose until 8 hours after a dose.
- Too much fluid intake may lead to a build up of water, which dilutes the salt in the body. This can occur with or without warnings or symptoms, which include unusually bad or prolonged headache, feeling or being sick, unexplained weight gain and in serious cases, fits or swelling of the brain. If you have any of these symptoms, stop the treatment and contact your doctor at once.

Instructions for use:
1. Blow your nose, then remove the dust cap on the spray bottle.
