Arixtra 2.5 mg / 0.5 ml solution for injection Pre-filled syringe – patient leaflet, side effects, dosage

1. What Arixtra is and what it is used for

Arixtra is a medicine that helps prevent blood clots from forming in the blood vessels (an antithrombotic agent).

Arixtra contains a synthetic substance called fondaparinux sodium. This stops a clotting factor Xa (“ten-A”) from working in the blood, and so prevents unwanted blood clots (thromboses) from forming in the blood vessels.

Arixtra is used to:

• prevent the formation of blood clots in the blood vessels

  of the legs or lungs after orthopaedic surgery (such as hip or knee surgery) or abdominal surgery

• prevent the formation of blood clots during and shortly after

  a period of restricted mobility due to acute illness

• treat some types of heart attack and severe angina

  (pain caused by narrowing of the arteries in the heart).

• treat blood clots in blood vessels that are near the surface

  of the skin of the legs (superficial-vein thrombosis).

2. What you need to know before you use Arixtra

Do not use Arixtra:

• if you are allergic to fondaparinux sodium or to any

  of the other ingredients of this medicine (listed in section 6)

• if you are bleeding excessively
• if you have a bacterial heart infection
• if you have very severe kidney disease.

→ Tell your doctor if you think any of these applies to you.

If they do, you must not use Arixtra.

Take special care with Arixtra:

Talk to your doctor or pharmacist before taking Arixtra:

• if you have previously had complications during treatment with heparin or heparin-like medicines causing a fall in the number of blood platelets (heparin-induced thrombocytopenia)

• if you have a risk of uncontrolled bleeding

  (haemorrhage) including:

  • stomach ulcer
  • bleeding disorders
  • recent bleeding into the brain (intracranial bleeding)
  • recent surgery on the brain, spine or eye
• if you have severe liver disease
• if you have kidney disease
• if you are 75 years old or older
• if you weigh less than 50 kg.

→ Tell your doctor if any of these applies to you.

How Arixtra is given

• Arixtra is given by injection under the skin (subcutaneously)

  into a skin fold of the lower abdominal area. The syringes are pre-filled with the exact dose you need. There are different syringes for the 2.5 mg and 1.5 mg doses. For step-by-step instructions please see over the page. To treat some types of heart attack, a health professional may give the first dose into a vein (intravenously).

• Do not inject Arixtra into muscle.

How long should Arixtra be taken for

You should continue Arixtra treatment for as long as your doctor has told you, since Arixtra prevents development of a serious condition.

If you inject too much Arixtra

Contact your doctor or pharmacist for advice as soon as possible, because of the increased risk of bleeding.

If you forget to take Arixtra

• Take the dose as soon as you remember. Do not inject a double dose to make up for a forgotten dose.

• If you are not sure what to do, ask your doctor

  or pharmacist.

Don’t stop using Arixtra without advice

STEP BY STEP GUIDE TO USING ARIXTRA

Instructions for use

These instructions are for both types of syringes (automatic and manual needle protection system). Where the instruction for a syringe is different this is clearly stated.

1. 1. Wash your hands thoroughly with soap and water and dry them with a towel.
2. 2.

   Remove the syringe from the carton and check that:

   • the expiry date has not passed

   • the solution is clear and colourless and doesn’t

     contain particles

   • the syringe has not been opened or damaged
3. 3. Sit or lie down in a comfortable position.

Choose a place in the lower

abdominal (tummy) area, at

least 5 cm below your belly

button (picture A).

Alternate the left and right

side of the lower abdominal

area at each injection. This will

help to reduce the discomfort at

the injection site.

If injecting in the lower abdominal

area is not possible, ask your

nurse or doctor for advice.

1. 4. Clean the injection area with an alcohol wipe.
2. 5. Remove the needle shield, by first twisting it (picture B1) and then pulling it in a straight line away from the body of the syringe (picture B2).

Discard the needle shield.

Important note

• Do not touch the needle or allow it to touch any surface before the injection.
• It is normal to see a small air bubble in this syringe. Do not try to remove this air bubble before making the injection - you may lose some of the medicine if you do.
• 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 (picture C).

1. 7. Hold the syringe firmly by the finger grip.

Insert the full length of the needle at right angles into the skin fold (picture D).

1. 8. Inject ALL of the contents of the syringe by pressing down on the plunger as far as it goes

(picture E).
