1. What DesmoMelt is what it is used for
Talk to your doctor or pharmacist before taking DesmoMelt. Take special care with DesmoMelt:
DesmoMelt are oral lyophiliates, they look like tables but are much softer and lighter. Intended for sublingual use (to be placed under the tongue where it will dissolve completely). They are reffered to as DesmoMelt or melt(s) in this leaflet.
DesmoMelt with food and drink: DesmoMelt is taken together with food, the intensity and duration of effect may be reduced.
DesmoMelt is available in two strengths: 120 or 240 micrograms. It contains Desmopressin acetate, an antidiuretic which reduces urine production.
All patients, in case of children their parents and, where applicable, responsible nursing staff should be carefully instructed to adhere to the fluid restrictions.
DesmoMelt is used to treat:
Other medicines and DesmoMelt: Please inform your doctor or pharmacist:
e DesmoMelt Do not take DesmoMelt:
Pregnancy, breast-feeding and fertility: 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. Blood pressure monitoring is recommended due to the increased risk of pre-eclampsia (a condition in pregnant women that can cause serious complications). Symptoms of pre-eclampsia include high blood pressure, oedema (swelling due to the build up of fluid).
DesmoMelt Always take this medicine exactly as your doctor has told you. Check with your doctor or pharmacist if you are not sure. The recommended dose is: The usual starting dose is one DesmoMelt 120 micrograms sublingually (under the tongue) at bedtime.

Like all medicines, this medicine can cause side effects, although not everybody gets them. You should avoid drinking large amounts of fluid while you are being treated with DesmoMelt, as this could lead to a build up of water which dilutes the salt in the body. This is a serious problem and may lead to convulsions. STOP TAKING DesmoMelt if you experience:
tightness or coughing If you experience any of the above side effects, you should contact your doctor or go to the nearest casualty department immediately. Common side effects may affect up to 1 in 10 people:

DesmoMelt is indicated for the treatment of primary nocturnal enuresis.
Posology
The recommended initial dose for children (from 5 years of age) and adults (up to 65 years of age) with normal urine concentrating ability who have primary nocturnal enuresis, is 120 micrograms at bedtime administered sublingually. If this dose is not sufficiently effective, the dose may be increased up to 240 micrograms, administered sublingually. Fluid restriction should be observed.
DesmoMelt is intended for treatment periods of up to 3 months. The need for continued treatment should be reassessed by means of a period of at least 1 week without DesmoMelt.
In the event of signs or symptoms of water retention and/or hyponatraemia (headache, nausea/vomiting, weight gain, and, in severe cases, convulsions) treatment should be interrupted until the patient has fully recovered. When restarting treatment strict fluid restriction should be enforced (see section 4.4).
If adequate clinical effect is not achieved within 4 weeks following appropriate dose titration the medication should be discontinued.
Special Populations
Elderly patients (65 years of age and older)
The initiation of treatment in patients over 65 years of age is not recommended (see section 4.3 and 4.4).
Renal impairment
DesmoMelt is contraindicated in patients with moderate and severe renal insufficiency (see section 4.3).
Hepatic impairment
No dose adjustment is needed for patients with hepatic impairment (see section 5.2).
Paediatric population
DesmoMelt is indication for treatment in this population (see section 4.2 above). Dose recommendations are the same as in adults.
Method of administration
Sublingual use, place the melt under the tongue where it dissolves without the need for water.
Food intake may reduce the intensity and duration of the antidiuretic effect at low doses of desmopressin (see section 4.5).
• Hypersensitivity to the active substance or to any of the excipients listed in section 6.1
• Known or suspected cardiac insufficiency and other conditions requiring treatment with diuretic agents. DesmoMelt should only be used in patients with normal blood pressure.
• Habitual or psychogenic polydipsia (resulting in a urine production exceeding 40 ml/kg/24 hours)
• Desmopressin should not be prescribed to patients over the age of 65
• Moderate and severe renal insufficiency (creatinine clearance below 50ml/min)
• Known hyponatremia
• Syndrome of inappropriate ADH secretion (SIADH)
Special warnings:
Care should be taken with patients who have reduced renal function and/or cardiovascular disease or cystic fibrosis. In chronic renal disease the antidiuretic effect of DesmoMelt would be less than normal.
When DesmoMelt is used for the treatment of enuresis, the fluid intake must be limited to a minimum from 1 hour before until the next morning (at least 8 hours) after administration. Treatment without concomitant reduction of fluid intake may lead to water retention and/or hyponatraemia with or without accompanying warning signs and symptoms (headache, nausea/vomiting, weight gain, and, in severe cases, convulsions).
All patients and, when applicable, their guardians should be carefully instructed to adhere to the fluid restrictions.
Precautions:
Severe bladder dysfunction and outlet obstruction should be considered before starting treatment.
Elderly patients and patients with serum sodium levels in the lower range of normal may have an increased risk of hyponatraemia.
Treatment with desmopressin should be interrupted during acute intercurrent illnesses characterised by fluid and/or electrolyte imbalance (such as systemic infections, fever, gastroenteritis).
Desmopressin should be used with caution in patients with conditions characterised by fluid and/or electrolyte imbalance.
Precautions must be taken in patients at risk for increased intracranial pressure.
Precautions to avoid hyponatraemia including careful attention to fluid restriction and more frequent monitoring of serum sodium must be taken in case of concomitant treatment with drugs, which are known to induce SIADH, e.g. tricyclic antidepressants, selective serotonin reuptake inhibitors, chlorpromazine and carbamazepine, case of concomitant treatment with NSAIDs.
Pharmacodynamic interactions
Substances which are known to induce SIADH e.g. tricyclic antidepressants, selective serotonin reuptake inhibitors, chlorpromazine and carbamazepine, as well as some antidiabetics of the sulfonylurea group particularly chlorpropamide, may cause an additive antidiuretic effect leading to an increased risk of water retention and/or hyponatraemia (see section 4.4).
NSAIDs may induce water retention and/or hyponatraemia.
Pharmacokinetic interactions
Concomitant treatment with loperamide may result in a 3-fold increase of desmopressin plasma concentrations, which may lead to an increased risk of water retention and/or hyponatraemia. Although not investigated, other drugs slowing intestinal transport might have the same effect.
A standardised 27% fat meal significantly decreased the absorption (rate and extent) of desmopressin tablets. No significant affect was observed with respect to pharmacodynamics (urine production and osmolality).
Food intake may reduce the intensity and duration of the antidiuretic effect at low oral doses of desmopressin tablet.
Pregnancy:
Caution should be exercised when prescribing to pregnant women.
Data on a limited number (n=53) of exposed pregnancies in women with diabetes insipidus indicate rare cases of malformations in children treated during pregnancy. To date, no other relevant epidemiological data are available. Animal studies do not indicate direct or indirect harmful effects with respect to pregnancy, embryonal/fetal development, parturition or postnatal development.
Caution should be exercised when prescribing to pregnant women. Blood pressure monitoring is recommended due to the increased risk of pre-eclampsia.
Breastfeeding:
Results from analyses of milk from nursing mothers receiving high dose desmopressin (300 micrograms intranasally) indicate that the amounts of desmopressin that may be transferred to the child are considerably less than the amounts required to influence diuresis. Therefore it is not considered necessary to stop breastfeeding.
DesmoMelt has no or negligible influence on the ability to drive and use machines.
The most serious adverse reaction with desmopressin is hyponatraemia, which is associated with headache, nausea, vomiting, decreased serum sodium, weight increase, malaise, abdominal pain, muscle cramps, dizziness, confusion, decreased consciousness and in severe cases convulsions and coma.
The cause of the potential hyponatraemia is the anticipated antidiuretic effect. The hyponatraemia is reversible and in children it is often seen to occur in relation to changes in daily routines affecting fluid intake and/or perspiration. In both adults and children special attention should be paid to the precautions addressed in section 4.4.

In case of hyponatraemia, the treatment of hyponatraemia should be individualised (see section 4.9).
Caution should be taken when substances with increased risk of water retention are taken concurrently with DesmoMelt, since the concurrent use may increase the risk of hyponatraemia (see section 4.4).
Anaphylactic reactions, Psychomotor hyperactivity and some Psychiatric reactions such as abnormal behaviour, emotional disorder, depression, hallucination & insomnia, have not been seen in clinical trials but spontaneous reports have been received.
In children, psychiatric disorders including affect lability, aggression, anxiety, mood swings & nightmare are generally reversed upon treatment discontinuation.
Isolated cases of allergic skin reactions and more severe general allergic reactions have been reported.
Other special populations:
Elderly patients and patients with serum sodium levels in the lower range of normal may have an increased risk of developing hyponatraemia (see section 4.4).
Reporting of suspected adverse reactions
Reporting suspected adverse reactions after authorisation of the medicinal product is important. It allows continued monitoring of the benefit/risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions via the Yellow Card Scheme, website: www.mhra.gov.uk/yellowcard.
Symptoms:
Overdose of DesmoMelt leads to a prolonged duration of action with an increased risk of water retention and/or hyponatraemia.
Treatment:
Although the treatment of hyponatraemia should be individualised, the following general recommendations can be given. Hyponatraemia is treated by discontinuing the desmopressin treatment, fluid restriction and symptomatic treatment if needed.
