Patient leaflet - Crusia 12 000 IU (120 mg)/0.8 ml solution for injection in Pre-filled syringe

1. What Crusia is and what it is used for

Crusia contains the active substance called enoxaparin sodium that is a low molecular weight heparin (LMWH).

Crusia works in two ways.

  1. 1) Stopping existing blood clots from getting any bigger. This helps your body to break them down and stops them from causing you harm
  2. 2) Stopping blood clots from forming in your blood.

Crusia can be used to:

  • Treat blood clots that are in your blood.
  • Stop blood clots from forming in your blood in the following situations:

    • Before and after an operation
    • When you have an acute illness and face period of limited mobility
    • When you have unstable angina (a condition when not enough blood gets to your heart)
    • After a heart attack
  • Stop blood clots forming in the tubes of your dialysis machine (used for people with severe kidney problems).

2. What you need to know before you use Crusia

Do not use Crusia

  • If you are allergic to enoxaparin sodium or any of the other ingredients of this medicine (listed in section 6). Signs of an allergic reaction include: rash, swallowing or breathing problems, swelling of your lips, face, throat or tongue.
  • If you are allergic to heparin or other low molecular weight heparins such as nadroparin, tinzaparin or dalteparin. • If you have had a reaction to heparin that caused a severe drop in the number of your clotting cells (platelets) - this reaction is called heparin-induced thrombocytopenia - within the last 100 days or if you have antibodies against enoxaparin in your blood.
  • If you are bleeding heavily or have a condition with a high risk of bleeding (such as stomach ulcer, recent surgery of the brain or eyes), including recent bleeding stroke.
  • If you are using Crusia to treat blood clots in your body and going to receive spinal or epidural anaesthesia or lumbar puncture within 24 hours.

Warnings and precautions

Crusia should not be used interchangeably with other medicines belonging to the group of low molecular weight heparins. This is because they are not exactly the same and do not have the same activity and instructions for use.

Talk to your doctor or pharmacist before using Crusia if:

  • you have ever had a reaction to heparin that caused a severe drop in the number of your platelets
  • you are going to receive spinal or epidural anesthesia or lumbar puncture (see Operations and Anaesthetics): a delay should be respected between Crusia use and this procedure
  • you have had a heart valve fitted
  • you have endocarditis (an infection of the inner lining of the heart)
  • you have history of gastric ulcer
  • you have had a recent stroke
  • you have high blood pressure
  • you have diabetes or problems with blood vessels in the eye caused by diabetes (called diabetic retinopathy)
  • you have had an operation recently on your eyes or brain
  • you are elderly (over 65 years old) and especially if you are over 75 years old
  • you have kidney problems
  • you have liver problems
  • you are underweight or overweight
  • you have high level of potassium in your blood (this may be checked with a blood test)
  • are currently using medicines which affect bleeding (see section below – Other medicines)

You may have a blood test before you start using this medicine and at intervals while you are using it; this is to check the level of the clotting cells (platelets) and potassium in your blood.

Children and adolescents

The safety and efficacy of enoxaparin has not been evaluated in children or adolescents.

Other medicines and Crusia

Tell your doctor or pharmacist if you are taking or might take/use any other medicines.

  • Warfarin – used for thinning the blood
  • Aspirin (also known as acetylsalicylic acid or ASA), clopidogrel or other medicines used to stop blood clots from forming (see also in section 3, “Changing of anticoagulant medicine”)
  • Dextran injection – used as a blood replacer
  • Ibuprofen, diclofenac, ketorolac or other medicines known as non-steroidal anti-inflammatory agents which are used to treat pain and swelling in arthritis and other conditions
  • Prednisolone, dexamethasone or other medicines used to treat asthma, rheumatoid arthritis and other conditions
  • Medicines which increase potassium level in your blood such as potassium salts, water pills, some medicines for heart problems.

Operations and Anaesthetics

If you are going to have a spinal puncture or an operation where an epidural or spinal anaesthetic is used, tell your doctor that you are using Crusia. See “Do not use Crusia”. Also, tell your doctor if you have any problem with your spine or if you ever had spinal surgery.

Pregnancy and breastfeeding

If you are pregnant, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.

If you are pregnant and have a mechanical heart valve, you may be at an increased risk of developing blood clots. Your doctor should discuss this with you.

If you are breast-feeding or plan to breast-feed, you should ask your doctor for advice before taking this medicine.

Driving and using machines

Crusia does not affect the ability to drive and operate machinery.

It is advised that the trade name and batch number of the product you are using are recorded by your healthcare professional.

Crusia contains sodium

This medicine contains less than 1 mmol sodium (23 mg) per dose, that is to say essentially “sodium free”.

3. How to use Crusia

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

Having this medicine

  • Your doctor or nurse will normally give you Crusia. This is because it needs to be given as an injection.
  • When you go home, you may need to continue to use Crusia and give it yourself (see instructions below on how to do this).
  • Crusia is usually given by injection underneath the skin (subcutaneous).
  • Crusia can be given by injection into your vein (intravenous) after certain types of heart attack or operation.
  • Crusia can be added to the tube leaving the body (arterial line) at the start of the dialysis session.

Do not inject Crusia into a muscle.

How much will be given to you

  • Your doctor will decide how much Crusia to give you. The amount will depend on the reason it is being used.
  • If you have problems with your kidneys you may be given a smaller amount of Crusia.
  • Treating blood clots that are in your blood

    • The usual dose is 150 IU (1.5 mg) for every kilogram of your weight each day or 100 IU (1 mg) for every kilogram of your weight twice a day.
    • Your doctor will decide how long you should receive Crusia.
  • Stopping blood clots forming in your blood in the following situations:

    ❖Operation or periods of limited mobility due to an illness

    • The dose will depend on how likely you are to develop a clot. You will be given 2,000 IU (20 mg) or 4,000 IU (40 mg) of Crusia each day.
    • If you are going to have an operation your first injection will be usually given 2 hours or 12 hours before your operation.
    • If you have restricted mobility due to illness, you will normally be given 4,000 IU (40 mg)

      of Crusia each day.

    • Your doctor will decide how long you should receive Crusia.

❖After you have had a heart attack

Crusia can be used for two different types of heart attack called STEMI (ST segment elevation myocardial infarction) or Non STEMI (NSTEMI). The amount of Crusia given to you will depend on your age and the kind of heart attack you have had.

NSTEMI type of heart attack:

  • The usual dose is 100 IU (1 mg) for every kilogram of weight every 12 hours.
  • Your doctor will normally ask you to take aspirin (acetylsalicylic acid) as well.
  • Your doctor will decide how long you should receive Crusia.

STEMI type of heart attack if you are under 75 years old:

  • An initial dose of 3,000 IU (30 mg) of Crusia will be given as injection into your vein.
  • At the same time you will also be given Crusia as an injection underneath your skin (subcutaneous injection). The usual dose is 100 IU (1 mg) for every kilogram of your weight, every 12 hours.
  • Your doctor will normally ask you to take aspirin (acetylsalicylic acid) as well.
  • Your doctor will decide how long you should receive Crusia.

STEMI type of heart attack if you are 75 years old or older:

  • The usual dose is 75 IU (0.75 mg) for every kilogram of your weight, every 12 hours.
  • The maximum amount of Crusia given for the first two injections is 7,500 IU (75 mg).
  • Your doctor will decide how long you should receive Crusia.

For patients that have an operation called percutaneous coronary intervention (PCI):

Depending on when you were last given Crusia, your doctor may decide to give an additional dose of Crusia before a PCI operation. This is by injection into your vein.

  1. 3.

    Stopping blood clots from forming in the tubes of your dialysis machine

    • The usual dose is 100 IU (1 mg) for every kilogram of your weight.
    • Crusia is added to the tube leaving the body (arterial line) at the start of the dialysis session. This amount is usually enough for a 4-hour session. However, your doctor may give you a further dose of 50 IU to 100 IU (0.5 to 1 mg) for every kilogram of your weight, if necessary.

Instructions for use of the syringe

How to give yourself an injection of Crusia

If you are able to give Crusia to yourself, your doctor or nurse will show you how to do this. Do not try to inject yourself if you have not been trained how to do so. If you are not sure what to do, talk to your doctor or nurse immediately. Performing the injection properly under the skin (called “subcutaneous injection”) will help reduce pain and bruising at the injection site.

Before injecting yourself with Crusia

  • Collect together the items that you need: syringe, alcohol swab or soap and water, and sharps container.

  • Check the expiry date on the medicine. Do not use if the date has passed.
  • Check the syringe is not damaged and the medicine in it is a clear solution. If not, use another

    syringe.

  • Make sure you know how much you are going to inject.
  • Check your abdomen to see if the last injection caused any redness, change in skin colour, swelling,

    oozing or is still painful. If so talk to your doctor or nurse.

Instructions on injecting yourself with Crusia:

(Instructions for syringes without safety device)

Preparing the injection site

  1. 1)

    Choose an area on the right or left side of your stomach. This should be at least 5 centimetres away from your belly button and out towards your sides.

    • Do not inject yourself within 5cm of your belly button or around existing scars or bruises.
    • Change the place where you inject between the left and right sides of your stomach, depending on the area you last injected.
JERINGAS-02�
  1. 2) Wash your hands. Cleanse (do not rub) the area that you will inject with an alcohol swab or soap and water.
  2. 3) Sit or lie in a comfortable position so you are relaxed. Make sure you can see the place you are going to inject. A lounge chair, recliner, or bed propped up with pillows is ideal.

Selecting your dose

  1. 1)

    Carefully pull off the needle cap from the syringe. Throw away the cap.

    • Do not press on the plunger before injecting yourself to get rid of air bubbles. This can lead to a loss of the medicine.
    • Once you have removed the cap, do not allow the needle to touch anything. This is to make sure the needle stays clean (sterile).
JERINGAS-04�
  1. 2) When the amount of medication in the syringe already matches your prescribed dose, there is no need to adjust the dose. You are now ready to inject.
  2. 3) When the dose depends on your body weight, you may need to adjust the dose in the syringe to match the prescribed dose. In that case, you can get rid of any extra medicine by holding the syringe pointing down (to keep the air bubble in the syringe) and ejecting the extra amount into a container.
  3. 4) A drop may appear at the tip of the needle. If this occurs, remove the drop before injecting by tapping on the syringe with the needle pointing down. You are now ready to inject.

Injecting

  1. 1)

    Hold the syringe in the hand you write with (like a pencil). With your other hand, gently pinch the cleaned area of your stomach between your forefinger and thumb to make a fold in the skin.

    • Make sure you hold the skin fold throughout the injection.
  2. 2) Hold the syringe so that the needle is pointing straight down (vertically at a 90° angle). Insert the full length of the needle into the skin fold.
JERINGAS-06�
  1. 3) Press down on the plunger with your thumb. This will send the medication into the fatty tissue of the stomach. Complete the injection using all of the medicine in the syringe.
  2. 4) Remove the needle from the injection site by pulling it straight out. Orient the needle away from the user and anyone else who is present. You can now let go of the skin fold.
JERINGAS-08�

When you have finished

  1. 1) To avoid bruising, do not rub the injection site after you have injected yourself.
  2. 2) Drop the used syringe into a sharps container. Close the container lid tightly and place the container out of reach of children. When the container is full, dispose of it as your doctor or pharmacist has instructed.

Any unused medicine or waste material should be disposed of in accordance with local requirements.

If you get the impression that the dose is either too strong (for example, you are experiencing unexpected bleeding) or too weak (for example, the dose doesn’t seem to be working), talk to your doctor or pharmacist.

Changing of anticoagulant treatment

  • Changing from Crusia to blood thinners called vitamin-K antagonists (e.g. warfarin)

    Your doctor will request you perform blood tests called INR and tell you when to stop Crusia accordingly.

  • Changing from blood thinners called vitamin-K antagonists (e.g. warfarin) to Crusia

    Stop taking the vitamin-K antagonist. Your doctor will request you perform blood tests called INR and tell you when to start Crusia accordingly.

  • Changing from Crusia to treatment with direct oral anticoagulant

    Stop taking Crusia. Start taking the direct oral anticoagulant 0-2 hours before the time you would have had the next injection, then continue as normal.

  • Changing from treatment with direct oral anticoagulant to Crusia

    Stop taking direct oral anticoagulant. Do not start treatment with Crusia until 12 hours after the final dose of direct oral anticoagulant.

Use in children and adolescents

The safety and efficacy of Crusia has not been evaluated in children or adolescents.

If you use more Crusia than you should

If you think that you have used too much or too little Crusia, tell your doctor, nurse or pharmacist immediately, even if you have no signs of a problem. If a child accidentally injects or swallows Crusia, take them to a hospital casualty department straight away.

If you forget to use Crusia

If you forget to give yourself a dose, have it as soon as you remember. Do not give yourself a double dose on the same day to make up for a forgotten dose. Keeping a diary will help to make sure you do not miss a dose.

If you stop using Crusia

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

It is important for you to keep having Crusia injections until your doctor decides to stop them. If you stop, you could get a blood clot which can be very dangerous.

4. Possible side effects

Like all medicines, this medicine can cause side effects, although not everybody gets them.

Like other similar medicines (medicines to reduce blood clotting), Crusia may cause bleeding which may potentially be life-threatening. In some cases the bleeding may not be obvious.

If you experience any bleeding event that does not stop by itself or if you experience signs of excessive bleeding (exceptional weakness, tiredness, paleness, dizziness, headache or unexplained swelling), consult your doctor immediately.

Your doctor may decide to keep you under closer observation or change your medicine.

Stop using Crusia and talk to a doctor or nurse at once if you get any signs of a severe allergic reaction (such as difficulty breathing, swelling of the lips, mouth, throat or eyes).

Stop using enoxaparin and seek medical attention immediately if you notice any of the following symptoms:

  • Any signs of a severe allergic reaction (such as difficulty breathing, swelling of the lips, mouth, throat or eyes).
  • A red, scaly widespread rash with bumps under the skin and blisters accompanied by fever. The symptoms usually appear at the initiation of treatment (acute generalised exanthematous pustulosis).

You should tell your doctor straight away

  • If you have any sign of blockage of a blood vessel by a blood clot such as:

    • cramping pain, redness, warmth, or swelling in one of your legs – these are symptoms of deep vein thrombosis
    • breathlessness, chest pain, fainting or coughing up blood – these are symptoms of a pulmonary embolism
  • If you have a painful rash of dark red spots under the skin which do not go away when you put pressure on them.

Your doctor may request you perform a blood test to check your platelet count.

Overall list of possible side effects:

Very common (may affect more than 1 in 10 people)

  • Bleeding.
  • Increases in liver enzymes.

Common (may affect up to 1 in 10 people)

  • You bruise more easily than usual. This could be because of a blood problem with low platelet counts.
  • Pink patches on your skin. These are more likely to appear in the area you have been injected with Crusia.
  • Skin rash (hives, urticaria).
  • Itchy red skin.
  • Bruising or pain at the injection site.
  • Decreased red blood cell count.
  • High platelet counts in the blood.
  • Headache.

Uncommon (may affect up to 1 in 100 people)

  • Sudden severe headache. This could be a sign of bleeding in the brain.
  • A feeling of tenderness and swelling in your stomach. You may have bleeding in your stomach.
  • Large red irregularly shaped skin lesions with or without blisters.
  • Skin irritation (local irritation).
  • You notice yellowing of your skin or eyes and your urine becomes darker in colour. This could be a liver problem.

Rare (may affect up to 1 in 1,000 people)

  • Severe allergic reaction. The signs may include: a rash, swallowing or breathing problems, swelling of your lips, face, throat or tongue.
  • Increased potassium in your blood. This is more likely to happen in people with kidney problems or diabetes. Your doctor will be able to check this by carrying out a blood test.
  • An increase in the number of eosinophils in your blood. Your doctor will be able to check this by carrying out a blood test.
  • Hair loss.
  • Osteoporosis (a condition where your bones are more likely to break) after long term use.
  • Tingling, numbness and muscular weakness (particularly in the lower part of your body) when you have had a spinal puncture or a spinal anaesthetic.
  • Loss of control over your bladder or bowel (so you cannot control when you go to the toilet).
  • Hard mass or lump at the injection site.
