6. Contents of the package and additional information

Clexanecontains an active ingredient called enoxaparin sodium. It belongs to a group of medications called “low molecular weight heparin” or LMWH.

How Clexane works

Clexaneacts in two ways:

1. Preventing existing blood clots from growing larger. This helps your body to break them down and prevent further damage.
2. Interfering with the formation of new blood clots.

What Clexane is used for

Clexanecan be used for:

• Treating blood clots
• Preventing blood clots from forming in the following situations:
• • before and after surgery
  • when you have a short-term illness and are unable to move for some time
  • if you have had a blood clot due to cancer, to prevent further clots from forming.
• Preventing blood clots from forming when you have unstable angina (a condition where not enough blood reaches the heart) or after a heart attack

• Preventing blood clots from forming in the tubes of the dialysis equipment (used in people with severe kidney problems).

Do not use Clexaneif:

• you are allergic to:
• • enoxaparin sodium or any of the other components of this medication (listed in section 6)
  • heparin or other low molecular weight heparins such as nadroparin, tinzaparin, or dalteparin.

The signs of an allergic reaction include: rash, difficulty breathing or swallowing, swelling of the face, lips, tongue, mouth, throat, or eyes.

• you have had a reaction to heparin that caused a severe decrease in the number of platelets in the last 100 days
• you have antibodies against enoxaparin in your blood
• you are bleeding heavily or have a high risk of bleeding due to:
• • stomach ulcer, recent brain or eye surgery, or cerebral hemorrhage.
• you are usingClexaneto treat blood clots, and will have in the next 24 hours:
• • lumbar or spinal puncture
  • surgery with spinal or epidural anesthesia.

Do not useClexaneif any of the above conditions apply. If you are unsure, consult your doctor or pharmacist before usingClexane.

Warnings and precautions

Do not interchangeClexanewith other “low molecular weight heparins” such as nadroparin, tinzaparina, or dalteparin. 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 useClexaneif:

• you have had a reaction to heparin that caused a severe decrease in the number of platelets

For patients undergoing percutaneous coronary intervention (PCI):

• Depending on when you were last administered an injection of Clexane, your doctor may decide to administer an additional dose of Clexane before a PCI procedure. It will be administered by intravenous injection.

1. Prevention of blood clot formation in dialysis apparatus tubes

• The usual dose is 100 UI (1 mg) per kilogram of body weight.
• Clexane is added to the tube that comes out of the body (arterial line) at the beginning of a dialysis session. This amount is usually sufficient for a 4-hour session. However, your doctor may perform a new injection of 50 UI to 100 UI (0.5 to 1 mg) per kilogram of body weight if necessary.

If you will be injecting Clexane yourself

If you can administer Clexane yourself, your doctor or nurse will show you how to do it. Do not attempt to inject yourself if you have not been shown 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 (which is called "subcutaneous injection"), it will help reduce pain and hematoma at the injection site.

Before injecting yourself with Clexane

• Prepare what you will need: syringe, cotton swab with alcohol or soap and water, and sharp object container
• 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 transparent. If not, use another syringe.
• Make sure you know the amount to be injected.
• Check in the area of your abdomen if the last injection caused redness, skin color change, swelling, pus, or pain that still persists. If this occurred, consult your doctor or nurse.

Instructions for injecting yourself with Clexane:

(Instructions for syringes without safety device)

Preparing the injection site

1. Choose a site on the right or left side of your abdomen. At least 5 cm from the navel and towards either side.
   • Do not inject within 5 cm of the navel or around it if there are scars or hematomas.
   • To inject, alternate the left and right sides of your abdomen, depending on where the last injection was administered.

1. Wash your hands. Clean (do not rub) the area where the injection will be made with a cotton swab with alcohol or 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 the injection will be made. It is best to do this in a recliner, a reclining chair, or a bed with pillows.

Selecting the dose

1. Remove the cap from the syringe needle carefully by pulling it. Dispose of the cap.
   • Do not press the plunger to remove air bubbles before injecting. This can result in 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 dose prescribed, 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 discard the excess medication by holding the syringe down (to keep the air bubble in the syringe) and expelling the excess into a container.
3. A drop may appear at the end of the needle. If this happens, you need to remove the drop before administering the injection by gently tapping the syringe with the needle pointing down. You are now ready to administer the injection.

Administering the injection

1. Hold the syringe with the hand that writes (like a pencil). With the other hand, gently pinch the area you cleaned on your abdomen, between your index finger and thumb, to form a fold in the skin.
   • Make sure to hold this fold of skin while the injection is administered.
2. Hold the syringe so that the needle points straight down (vertically at a 90-degree angle). Insert the entire needle into the fold of skin.

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

When you have finished

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

Change of anticoagulant medication

• Change from Clexane to medications that reduce blood clotting called vitamin K antagonists (such as warfarin)

Your doctor will ask you to have a blood test to determine a parameter called INR and will tell you when to stop taking Clexane.

• Change from vitamin K antagonists (such as warfarin) to Clexane

Stop taking the vitamin K antagonist. Your doctor will ask you to have a blood test to determine a parameter called INR and will tell you when to start taking Clexane.

• Change from Clexane to direct oral anticoagulants

Stop taking Clexane. Start taking the direct oral anticoagulant from 0 to 2 hours before the time when you would have had the next injection, and then continue as usual.

• Change from direct oral anticoagulants to Clexane

Stop taking the direct oral anticoagulant. Do not start taking Clexane until 12 hours after the last dose of the direct oral anticoagulant.

If you use more Clexane than you should

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

In case of overdose or accidental administration, consult your doctor immediately or go to the nearest hospital emergency department, 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 Clexane

If you forget to administer a dose, do it as soon as you remember. Do not use a double dose on the same day to compensate for the missed doses. To ensure that you do not forget any doses, it may be helpful to use a calendar.

If you interrupt treatment with Clexane

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

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

Like all medicines, this medicine may cause side effects, although not everyone will experience them.

Severe side effects
