1. What Danaparoid Sodium is and what it is used for

Danaparoid sodium, the active ingredient in Danaparoid Sodium, is a medicine that prevents blood from clotting (anticoagulant), and belongs to a group of medicines called heparinoids.

Danaparoid Sodium prevents the formation of blood clots in blood vessels, and is used in patients who have an increased risk of blood clot formation, and in patients who are allergic to another medicine called heparin.

You should ask your doctor if you are unsure why you have been given Danaparoid Sodium.

2. Before you are given Danaparoid Sodium

You should not be given Danaparoid Sodium if:

  • you are allergic (hypersensitive) to danaparoid sodium, or any of the other ingredients of Danaparoid Sodium.
  • you are being treated for blood clots, and are having a spinal or epidural anaesthetic
  • you are prone to bleeding easily, unless you cannot be given heparin
  • you have an ulcer, unless the ulcer is the reason for your operation
  • have had a stroke
  • are bleeding and it can't be stopped
  • you have severe kidney or severe liver disease, unless you cannot be given heparin
  • have very high blood pressure
  • have damage to the retina of the eye due to diabetes
  • have an infection of the inner lining and valves of the heart (acute bacterial endocarditis).
  • previous treatment with heparins (a group of medicines often used to treat blood clots) caused a large drop in the number of a type of blood cell called platelets, and if a blood test showed that this may happen with Danaparoid Sodium

    • have an active stomach ulcer
    • a history of asthma or allergy

as this medicine contains sodium sulphite (see Important Information about some of the Ingredients of Danaparoid Sodium, below).

Taking other medicines

Some medicines can affect the way Danaparoid Sodium works, or Danaparoid Sodium itself can affect how other medicines taken at the same time work. These include:

  • oral anticoagulants (medicines used to stop blood clots)
  • aspirin or anti-rheumatics
  • steroids.
  • Tell your doctor or pharmacist if you are taking or have recently taken any other medicines, including medicines obtained without a prescription.

Ask your doctor or pharmacist for advice before taking any medicine.

Danaparoid Sodium is not known to have any effects on the ability to drive, or use machinery.

Important information about some of the ingredients of Danaparoid Sodium

This medicine contains less than 1 mmol sodium (23mg) per dose - that is essentially ‘sodium free’.

  • Danaparoid Sodium contains sodium sulphite which may rarely cause severe hypersensitivity reactions and a difficulty in breathing (bronchospasm).

3. How Danaparoid Sodium is given

Adults and elderly

Danaparoid Sodium can be used in children, but the doctor will decide the dose as experience is limited.

If you are given more Danaparoid Sodium than you should

Danaparoid Sodium will be given to you by a doctor or nurse so you are unlikely to be given too much medicine. However, if too much Danaparoid Sodium is given you may bleed too much. This may be shown by:

  • nosebleeds, bleeding gums;
  • blackened stools (may indicate blood loss from stomach or intestines);
  • blood in the urine;

More about Danaparoid Sodium

Danaparoid Sodium contains a natural substance, derived from pig intestine, which prevents the formation of blood clots in blood vessels (thrombosis).

Blood clots which form in veins may restrict the blood flow causing tissue to die. Small parts of the clot can break off and may block the blood circulation in the lungs. A blood clot in the lungs may be very serious.

Patients who are bedridden have an increased risk of clot formation in the veins of the legs, especially if they have undergone an operation. These patients receive Danaparoid Sodium to prevent the formation of blood clots.
