Patient leaflet - Demovo 360 micrograms/ml oral solution

1. What Demovo is and what it is used for

The ingredient that makes

Demovo work (the active

substance) is called

desmopressin. Desmopressin

is very similar to a substance

that is produced naturally

in the body (the pituitary

hormone vasopressin), which

temporarily reduces the

amount of urine produced

by the body. This medicine

is intended for oral use only.

This medicine is used to treat:

  • Central diabetes insipidus,

    a disease characterised

    by causing extreme thirst

    and continuous production

    of large volumes of dilute

    urine as a result of

    insufficient production of

    the hormone vasopressin.

  • Bed-wetting (involuntary

    nightly urination or primary

    nocturnal enuresis) in

    patients older than 5 years

    with normal capacity to

    concentrate urine.

2. What you need to know before you take Demovo

Do not take Demovo:

  • 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)

    Warnings and precautions

    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.

Other medicines and Demovo

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.

Demovo with food and drink

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.

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.

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.

Driving and using machines

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).

Demovo contains sodium

This medicine contains less than 1 mmol sodium (23 mg) per ml, that is to say

essentially ‘sodium free’.

3. How to take Demovo

Always take this medicine exactly as your doctor or pharmacist has told you. Check with your doctor or pharmacist if you are not sure.
