1. What is Crusia and what is it used for

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

Crusia works in two ways:

1. Preventing existing blood clots from getting bigger. This helps your body to break them down and stop them from causing harm.
2. Stopping new blood clots from forming.

Crusia can be used to:

• Treat blood clots.
• Prevent blood clots from forming in the following situations:

• Before and after surgery.
• When you have an acute illness and are about to undergo a period of reduced mobility.
• If you have had a blood clot due to cancer, to prevent more clots from forming.
• When you have unstable angina (a condition where not enough blood reaches the heart).
• After a heart attack.

• Prevent blood clots from forming in the tubes of a dialysis machine (used in 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, problems swallowing or breathing, swelling of the 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 decrease in the number of cells involved in blood clotting (platelets) - this reaction is called heparin-induced thrombocytopenia - in the last 100 days or if you have antibodies against enoxaparin in your blood.
• If you are bleeding heavily or have a high risk of bleeding (such as a stomach ulcer, recent eye or brain surgery), including a recent hemorrhagic stroke.
• If you are using Crusia to treat blood clots and are going to have spinal or epidural anesthesia or a lumbar puncture within 24 hours.

Warnings and Precautions

Crusia should not be exchanged with other low molecular weight heparin medicines. This is because they are not exactly the same and do not have the same activity or instructions for use.

Consult your doctor or pharmacist before starting to use Crusia if:

• You have ever had a reaction to heparin that caused a severe decrease in the number of platelets.
• You are going to have spinal or lumbar anesthesia or a lumbar puncture (see "Surgery and anesthesia"): a delay must be observed between Crusia and the use of this procedure.
• You have had a heart valve implanted.
• You have endocarditis (an infection of the inner lining of the heart).
• You have a history of stomach ulcers.
• You have recently had a stroke.
• You have high blood pressure.
• You have diabetes or problems with the blood vessels in your eyes caused by diabetes (called diabetic retinopathy).
• You have recently had eye or brain surgery.
• You are an elderly person (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 levels of potassium in your blood (which could be checked with a blood test).
• You are currently using medicines that affect bleeding (see below - Use of Crusia with other medicines).

You may need to have a blood test before starting to use this medicine and while you are using it; this is to check the level of cells involved in blood clotting (platelets) and the levels of potassium in your blood.

Children and Adolescents

The safety and efficacy of enoxaparin in children and adolescents have not been established.

Use of Crusia with Other Medicines

Tell your doctor or pharmacist if you are using, have recently used, or might use any other medicines.

• Warfarin - used to reduce blood clotting.
• Aspirin (also known as acetylsalicylic acid or ASA), clopidogrel, or other medicines used to prevent blood clots from forming (see also section 3, "Change of anticoagulant treatment").
• Dextran injection - used as a blood substitute.
• Ibuprofen, diclofenac, ketorolac, and other medicines known as non-steroidal anti-inflammatory drugs used to treat pain and inflammation in arthritis and other diseases.
• Prednisolone, dexamethasone, and other medicines used to treat asthma, rheumatoid arthritis, and other diseases.
• Medicines that increase the level of potassium in your blood, such as potassium salts, diuretics, and some medicines used to treat heart problems.

Surgery and Anesthesia

If you are going to have a lumbar puncture or undergo surgery where spinal or epidural anesthesia is used, tell your doctor that you are using Crusia. See "Use of Crusia with other medicines". Also, tell your doctor if you have any problems with your spine or if you have 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 using this medicine.

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

If you are breastfeeding or plan to breastfeed, you should consult your doctor before using this medicine.

Driving and Using Machines

Crusia does not affect your ability to drive or use machines.

It is recommended that your healthcare professional records the trade name and batch number of the product you are using.

Crusia Contains Sodium

This medicine contains less than 23 mg of sodium (1 mmol) per dose; it is essentially "sodium-free".

3. How to use Crusia

Follow your doctor's or pharmacist's administration instructions for this medication exactly. If in doubt, consult your doctor or pharmacist again.

Using the medication

• Normally, your doctor or nurse will administer Crusia to you. This is because it must be administered by injection.
• When you return home, you may need to continue using Crusia and administer it yourself (see the instructions on how to do this).
• Crusia is usually administered by subcutaneous injection (under the skin).
• Crusia can be administered by intravenous injection (into your veins) after certain types of heart attacks and surgical operations.
• Crusia can be added to the tube coming out of your body (arterial line) at the start of the dialysis session.

Do not administer Crusia into a muscle (intramuscularly).

How much will be administered to you

• Your doctor will decide the amount of Crusia to be administered to you. The amount will depend on the reason for its use.
• If you have kidney problems, you may be administered a smaller amount of Crusia.

1. Treatment of blood clot formation:

• The usual dose is 150 UI (1.5 mg) per kilogram of body weight per day or 100 UI (1 mg) per kilogram of body weight twice a day.
• Your doctor will decide how long you will receive Crusia.

1. Prevention of blood clot formation in the following situations:

Surgery or periods of limited mobility due to illness

• The dose will depend on your likelihood of developing a clot. You will be administered 2,000 UI (20 mg) or 4,000 UI (40 mg) of Crusia per day.
• If you are going to have surgery, you will usually be given the first injection 2 or 12 hours before the operation.
• If you have reduced mobility due to illness, you will usually be administered 4,000 UI (40 mg) of Crusia per day.
• Your doctor will decide how long you will receive Crusia.

After having a heart attack

Crusia can be used in two different types of heart attacks, known as STEMI (ST-elevation myocardial infarction) or non-STEMI. The amount of Crusia administered to you will depend on your age and the type of heart attack you had.

Non-STEMI heart attack:

• The usual dose is 100 UI (1 mg) per kilogram of body weight every 12 hours.
• Usually, your doctor will also tell you to take aspirin (acetylsalicylic acid).
• Your doctor will decide how long you will receive Crusia.

STEMI heart attack if you are under 75 years old:

• You will be administered an initial intravenous injection of 3,000 UI (30 mg) of Crusia.
• At the same time, you will be administered a subcutaneous injection of Crusia. The usual dose is 100 UI (1 mg) per kilogram of body weight every 12 hours.
• Usually, your doctor will also tell you to take aspirin (acetylsalicylic acid).
• Your doctor will decide how long you will receive Crusia.

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

• The usual dose is 75 UI (0.75 mg) per kilogram of body weight every 12 hours.
• The maximum amount of Crusia administered in the first two injections is 7,500 UI (75 mg).
• Your doctor will decide how long you will receive Crusia.

For patients undergoing percutaneous coronary intervention (PCI):

Depending on when you last received an injection of Crusia, your doctor may decide to administer an additional dose of Crusia before a PCI procedure. This would be by intravenous injection.

1. Prevention of blood clot formation in dialysis tubes:

• The usual dose is 100 UI (1 mg) per kilogram of body weight.
• Crusia is added to the tube coming out of your body (arterial line) at the start of the dialysis session. This amount is usually sufficient for a 4-hour session. However, your doctor may administer an additional injection of 50 UI to 100 UI (0.5 to 1 mg) per kilogram of body weight if necessary.

Instructions for using the syringe

If you are going to inject Crusia yourself

If you can administer Crusia yourself, your doctor or nurse will show you how to do it. Do not attempt to inject yourself if you have not been taught how to do it. If you are unsure what to do, consult your doctor or nurse immediately. If the injection is performed correctly under the skin (subcutaneously), this will help reduce pain and bruising at the injection site.

Before injecting Crusia yourself

Prepare what you will need: syringe, cotton swab with alcohol or soap and water, and a container for sharp objects.

Check the expiration date of the medication. If it has expired, do not use it.

Check that the syringe is not damaged and that the medication solution is clear. If it is not, use another syringe.

Make sure you know the amount to be injected.

Check the area of your stomach where you last injected to see if there is any redness, skin color change, swelling, discharge, or pain that still persists. If this occurs, consult your doctor or nurse.

Instructions for injecting Crusia yourself:

(Instructions for syringes without a safety device)

Preparing the injection site

1. Choose an area on the right or left side of your stomach. At least 5 cm from your navel and towards either side.

Do not inject within 5 cm of your navel or around it if there are scars or bruises.

To inject, alternate the left and right sides of your stomach, depending on where you last injected.

1. Wash your hands. Clean (do not rub) the area where you will perform the injection with a cotton swab with alcohol or with soap and water.
2. Sit or lie down in a comfortable position so that you are relaxed. Make sure you can see the area where you will inject. The most suitable place is on a couch, a reclining chair, or in a bed with pillows.

Selecting the dose

1. Carefully remove the needle cap from the syringe by pulling it. Discard the cap.

Before injecting, do not press the plunger to eliminate air bubbles. This can cause a loss of medication.

Once you have removed the cap, do not touch anything with the needle. This will ensure that the needle remains clean (sterile).

1. When the amount of medication in the syringe matches the prescribed dose, there is no need to adjust the dose. You are now ready to administer the injection.
2. When the dose depends on your body weight, you may need to adjust the dose in the syringe to match the prescribed dose. In this case, you can get rid of the excess medication by keeping the syringe pointing downwards (to keep the air bubble in the syringe) and expelling the excess into a container.
3. A drop may appear at the tip of the needle. If this happens, you must eliminate the drop before administering the injection by gently tapping the syringe with the needle pointing downwards. You are now ready to administer the injection.

Administering the injection

1. Hold the syringe with the hand you write with (as if it were a pencil). With the other hand, gently pinch the area you cleaned on your stomach, between your index finger and thumb, to form a fold in the skin.

Make sure to hold this skin fold while the injection lasts.

1. Keep the syringe so that the needle points straight down (vertically at a 90-degree angle). Insert the entire needle into the skin fold.

1. Press the plunger with your thumb. This will administer the medication into the fatty tissue of your stomach. Complete the injection using all the medication in the syringe.
2. Remove the needle from the injection site by pulling it straight out. Keep the needle away from yourself and others. You can now release the skin fold.

When you have finished

1. To avoid bruising, do not rub the injection site after injecting.
2. Place the used syringe in the container for sharp objects. Close the container lid tightly and keep it out of the reach of children. When the container is full, dispose of it as your doctor or pharmacist has instructed.

The disposal of unused medication and all materials that have come into contact with it will be carried out in accordance with local regulations.

If you think the dose is too high (for example, if you have an unexpected bleeding) or too low (for example, if the dose does not seem to be working), consult your doctor or pharmacist.

Instructions for syringes with a safety device:

Preparing the injection site

1. Choose an area on the right or left side of your stomach. At least 5 cm from your navel and towards either side.

Do not inject within 5 cm of your navel or around it if there are scars or bruises.

2. Remove the needle from the injection site by pulling it straight out and keeping your finger on the plunger. Keep the needle away from yourself and others. The safety system will be activated by firmly pressing the plunger. The protective sleeve will automatically cover the needle and emit an audible click that confirms the activation of the device. You can now release the skin fold.

When you have finished

1. To avoid bruising, do not rub the injection site after injecting.
2. Place the used syringe in the container for sharp objects. Close the container lid tightly and keep it out of the reach of children. When the container is full, dispose of it as your doctor or pharmacist has instructed.

The disposal of unused medication and all materials that have come into contact with it will be carried out in accordance with local regulations.

If you think the dose is too high (for example, if you have an unexpected bleeding) or too low (for example, if the dose does not seem to be working), consult your doctor or pharmacist.

Changing anticoagulant treatment

• Changing from Crusia to anticoagulant medications called vitamin K antagonists (e.g., warfarin)

Your doctor will request a blood test to determine a parameter called INR and will tell you when to stop treatment with Crusia.

• Changing from vitamin K antagonist medications (e.g., warfarin) to Crusia

Stop using the vitamin K antagonist. Your doctor will request a blood test to determine a parameter called INR and will tell you when to start using Crusia.

• Changing from Crusia to treatment with direct oral anticoagulants

Stop using Crusia. Start taking the direct oral anticoagulant 0-2 hours before the next scheduled injection, and then continue as usual.

• Changing from direct oral anticoagulant treatment to Crusia

Stop taking the direct oral anticoagulant. Do not start treatment with Crusia until 12 hours have passed since the last dose of the direct oral anticoagulant.

If you use more Crusia than you should

If you think you have used too much or too little Crusia, inform your doctor, nurse, or pharmacist immediately, even if you do not have any signs of problems. If a child accidentally injects or swallows Crusia, take them to the emergency department of a hospital immediately.

In case of overdose or accidental administration, consult your doctor or go to the emergency department of the nearest hospital, bringing this leaflet with you, or call the Toxicology Information Service, phone 91 562 04 20, indicating the medication and the amount administered.

If you forget to use Crusia

If you forget to administer a dose, do so as soon as you remember. Do not use a double dose on the same day to make up for missed doses. To ensure you do not miss any doses, it may be helpful to use a diary.

If you stop treatment with Crusia

If you have any other questions about using this medication, ask your doctor, pharmacist, or nurse.

It is essential that you continue to receive Crusia until your doctor decides to stop treatment. If you stop using it, a blood clot may form, which can be very dangerous.

4. Possible Adverse Effects

Like all medicines, this medicine may cause adverse effects, although not all people suffer from them.

Like other similar medicines (medicines to reduce blood clots), Crusia could cause bleeding, which could potentially put your life at risk. In some cases, the bleeding may not be evident.

If you notice any episode of bleeding that does not stop by itself or if you notice signs of excessive bleeding (unusual weakness, fatigue, paleness, dizziness, headache, or unexplained swelling), consult your doctor immediately.

Your doctor may decide to keep you under strict observation or change your medication.

Interrupt treatment with enoxaparin and inform your doctor or nurse immediately if you experience any of the following symptoms:

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

You should inform your doctor immediately

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

• cramp-like pain, redness, heat, or swelling in one of your legs - which are symptoms of deep vein thrombosis.
• difficulty breathing, chest pain, fainting, or coughing up blood - which are symptoms of pulmonary embolism.

• If you have a painful skin rash with dark red spots under the skin that do not disappear when pressed.

Your doctor may request a blood test to check the number of platelets.

General List of Possible Adverse Effects:

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

• Bleeding.
• Increased liver enzymes.

Common (may affect up to 1 in 10 people)
