What Arixtra is used for

Arixtra is used to prevent blood clots forming in patients who are recovering from orthopaedic or abdominal surgery. Arixtra is also used to treat blood clots once they have formed. Arixtra contains the medication fondaparinux sodium, a synthetic compound which helps prevent blood clots forming in blood vessels. This type of blood clot, also called deep venous thrombosis, or DVT, can occur in patients who are confined to bed after hip or knee surgery. Arixtra is also used to treat some types of heart attacks and severe angina (a pain caused by narrowing of the arteries in the heart).

Your doctor may have prescribed Arixtra for another reason. Ask your doctor if you have any questions about why Arixtra has been prescribed for you.

Arixtra is not addictive.

This medicine is available only with a doctor’s prescription.

How Arixtra is given

Follow all directions given to you by your doctor or pharmacist carefully.

They may differ from the information contained in this leaflet.

How much is given

The usual dose of Arixtra is 2.5 mg given once a day, starting after your operation. Arixtra may be given for up to 31 days.

How it is given

Arixtra is given to you as a subcutaneous injection (an injection just under the skin). To treat some types of heart attack, the health professional only may give the first dose intravenously (into a vein).

Arixtra should NOT be given as an intramuscular injection (an injection into the muscle).

The injections can be given by a doctor or nurse, or you may be taught how to give the subcutaneous injections to yourself.

Instructions on how to use the Arixtra syringe subcutaneously are given at the end of this leaflet.

Overdose

Immediately telephone your doctor or the Poisons Information Centre (telephone Australia 13 11 26) for advice, or go to Accident and Emergency at the nearest hospital, if you think that you or anyone else may have taken too much Arixtra. Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention.

Overdose may lead to an increased risk of bleeding.

  • chest pain or difficulty in breathing

These may be signs that a blood clot has formed.

Arixtra helps most people at risk of blood clots following surgery, but it may have unwanted side effects in some people. All medicines can have side effects.

Method of administration

Arixtra is administered by subcutaneous injection (an injection just under the skin). Arixtra is for single use in one patient only. Discard any residue.

The solution should be inspected visually for particles and discoloration prior to administration. If present, do not proceed with the injection.

Subcutaneous administration

The sites of subcutaneous injection should be on the fatty tissues on the abdominal area. It is important to alternate between the left and the right sides. To avoid the loss of medicinal product when using the pre-filled syringe do not expel the air bubble from the syringe before injection. The whole length of the needle should be inserted between the thumb and forefinger (see figures 2 and 3). The skin fold should be held throughout the injection.

Arixtra is intended for use under a physician’s guidance. Patient’s may self-inject only if their physician determines that it is appropriate, and with medical follow-up as necessary. Proper training in subcutaneous injection technique should be provided. Instructions for self-administration subcutaneously are included below.

The parts of the syringe with an automatic needle protection system are:

  1. Needle shield
  2. Plunger
  3. Finger-grip
  4. Security sleeve

To use the Arixtra syringe, remove the needle shield, by first twisting it and then pulling it straight off (figure 1).

Discard the needle shield.

For subcutaneous administration:

Gently pinch the skin that has been cleaned to make a fold. Hold the fold between the thumb and the forefinger during the entire injection (figure 2).

Insert the full length of the needle perpendicularly (at an angle of 90°) into the skin fold (figure 3).

Inject ALL of the content of the syringe by pressing down on the plunger as far as it goes (figure 4), and then release it: the needle will withdraw automatically from the skin into a security sleeve and then will be locked permanently (figure 5).

Discard the used syringe in a safe manner by using a sharps disposal container. This is usually available at the local community pharmacy.
