• if you are allergic (hypersensitive) to desmopressin or any of the other ingredients of this medicine (listed in section 6)
• if you drink unusually large amounts of fluid (have habitual or psychogenic polydipsia)
• if you take medicines which increase urine production (diuretics)
• if you suffer from heart problems
• if you suffer predisposition to or have low levels of sodium in your blood (hyponatremia)
• if you suffer from reduced kidney function
• if you have uncontrolled blood pressure
• if you suffer from the ‘Syndrome of Inappropriate High Secretion of Antidiuretic Hormone’ (SIADH)

Talk to your doctor or pharmacist before taking this medicine.

When taking this medicine, avoid excessive fluid intake because it may lead to a build-up of water in the body and / or decrease in blood sodium with or without side effects (see section 4 – Possible side effects).

Special care with this medicine is required to avoid build-up of water in the body and decreased blood sodium:

• if you are elderly
• if you have a medical condition causing fluid and / or electrolyte imbalance in the body, such as an infection, fever or stomach upset
• if you suffer from a serious bladder problem or impaired urine outflow
• if you suffer from asthma, epilepsy and migraine
• if you have reduced renal function and / or cardiovascular disease. In chronic renal disease, the antidiuretic effect of desmopressin would be less than usual.

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines, especially:

• Tricyclic or SSRI antidepressants (used to treat depression)
• Carbamazepine (used to treat epilepsy)
• Chlorpromazine (used to treat psychosis or schizophrenia)
• Medicines for pain and / or inflammation called non-steroidal anti-inflammatory drugs (NSAIDs) e.g. indomethacin, ibuprofen, acetylsalicylic acid
• Loperamide (used to treat diarrhoea)
• Diuretic agents

These medicinal products increase the risk of build-up of water, which dilutes the salt in the body.

• Dimeticone (used in the treatment of wind), due to decreased absorption of desmopressin.

At low doses, this medicine may be affected by food intake. If you notice that this medicine is less effective, then you should take it without food before increasing the dose.

When using this medicine for bed-wetting keep your fluid intake to a minimum from 1 hour before you take the Demovo dose until 8 hours after a dose.

If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.

It is preferable to avoid using this medicine during pregnancy.

Desmopressin passes into breast milk. If you are going to be treated with desmopressin, you should stop breast-feeding.

Demovo does not affect your ability to drive and use machines.

Demovo contains sodium methyl parahydroxybenzoate and sodium propyl parahydroxybenzoate, which may cause allergic reactions (possibly delayed).

This medicine contains less than 1 mmol sodium (23 mg) per ml, that is to say essentially ‘sodium free’.

Treatment of central diabetes insipidus:

Adults and Children: Your doctor will prescribe the dose most suitable for you. The usual starting dose is 0.25 ml (90 micrograms) three times daily. Subsequently, the doctor will adjust the dose according to individual patient response.

The usual daily dose is between 0.5 ml (180 micrograms) to 3 ml (1080 micrograms) of this medicine. The maintenance dose ranges from 0.25 to 0.5 ml (90 – 180 micrograms) of this medicine three times per day.

It is important to note if symptoms of build-up of water in the body and / or decreased blood sodium appear (see section 4 – Possible side effects). If so, treatment will be stopped and the dose will be changed.

Bed-wetting (involuntary nightly urination or primary nocturnal enuresis) in patients older than 5 years:

Adults and Children: The usual starting dose is 0.5 ml (180 micrograms) of this medicine one hour before bedtime. The dose may be increased up to 1 ml (360 micrograms) of this medicine if the starting dose is not enough. The need for continued treatment is normally checked every three months by introducing a treatment free period of at least one week.

Elderly: If the doctor decides to treat you, your blood sodium levels should be measured before and three days after starting the treatment and if the dose is increased or at any time your doctor finds it necessary.

Monitoring your fluid intake is important. If symptoms of build-up of water in the body and / or decreased blood sodium occur (see section 4 – Possible side effects), discontinue treatment. Once treatment is restored, fluid intake will be rigorously controlled.

1. Open the bottle (on first opening the seal is broken).

2. Insert the oral syringe into the pourer and turn the bottle upside down to fill it with the dose to be administered.

3. Take the oral syringe out of the bottle and check to see that the correct amount appears in the bottom of the syringe.
4. Hold the syringe to your mouth and release the dose into your mouth.

5. Rinse with water after each use and close the bottle. Keep the bottle in the outer carton to protect from light.

An overdose may lengthen the effect of desmopressin and increase the risk of water build up in the body and / or low levels of sodium in your blood. Symptoms may include headache, nausea and vomiting, weight gain and in severe cases convulsions. It is recommended to stop the treatment, restrict fluid intake and start symptomatic treatment if necessary.

If you take more Demovo than prescribed, contact your doctor or pharmacist immediately.

Do not take a double dose to make up for a forgotten dose.

Do not stop taking Demovo before completing the treatment as it may not have the expected effect. You should only change or stop your treatment if advised by your doctor.

If you get any side effects, talk to your doctor or pharmacist. This includes any possible side effects not listed in this leaflet. You can also report side effects directly via the Yellow Card Scheme. Website: www.mhra.gov.uk/yellowcard or search for MHRA Yellow Card in the Google Play or Apple App Store.
