Arixtra® 7.5 mg/0.6 ml solution for injection – patient leaflet, side effects, dosage

1. What Arixtra is and what it is used for

Arixtra is a medicine that treats or helps to 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 treat adults with a blood clot in the blood vessels of their legs (deep vein thrombosis) and/or lungs (pulmonary embolism).

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 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.

^➔ Tell your doctor if any of these applies to you.

Children and adolescents

Arixtra has not been tested in children and adolescents under the age of 17 years.

Other medicines and Arixtra

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines. This includes medicines you bought without a prescription. Some other medicines may affect the way that Arixtra works or be affected by Arixtra.

Pregnancy and breast-feeding

Arixtra should not be prescribed to pregnant women unless clearly necessary. Breast-feeding is not recommended during treatment with Arixtra. 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.

Arixtra contains sodium

This medicinal product contains less than 23 mg of sodium in each dose and therefore is essentially sodium-free.

Arixtra syringe contains latex

The syringe needle shield contains latex that has the potential to cause allergic reactions in latex sensitive individuals.

^➔ Tell your doctor if you are allergic to latex before being treated with Arixtra.

3. How to use Arixtra

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

You should inject at about the same time each day.

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 5 mg, 7.5 mg and 10 mg doses. For step-by-step instructions please see over the page.
• 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

If you stop the treatment before your doctor told you to, the blood clot may not be treated properly and you may also be at risk of developing a new blood clot in a vein of your leg or in the lung. Contact your doctor or pharmacist before stopping.

If you have any further questions on the use of this medicine, ask your doctor or pharmacist.

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 to slightly yellow 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 Picture A 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.

  bubble before making the

  injection – you may lose some

  of the medicine if you do.
