CLEXANE 4 000IU [40 MG]/0.4ML SYRINGES, ENOXAPARIN SODIUM 4 000IU [40 MG]/0.4ML SYRINGES - patient leaflet, side effects, dosage

1. what clexane is and what it is used for

Clexane contain the active substance called enoxaparin sodium. This belongs to a group of medicines called ‘low molecular weight heparin’ or LMWH.

How Clexane works

Clexane works in two ways:

• 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 ) Stopping new blood clots from forming in your blood.

What Clexane is used for

Clexane can be used to:

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

o before and after an operation

o when you have a short-term illness and will not be able to move around for some time.

o if you have experienced a blood clot due to cancer to prevent further clots from forming.

• Stop blood clots from forming when you have unstable angina (where not enough blood gets to your heart) or after a heart attack
• Stop blood clots from forming in the tubes of your dialysis machine (used for people with severe kidney problems).

2. what you need to know before you use clexane

Do not use Clexane if:

• you are allergic to:

o enoxaparin sodium or any of the other ingredients of this medicine (listed in section 6) o heparin or other low molecular weight heparins such as nadroparin, tinzaparin or dalteparin. Signs of an allergic reaction include: rash, difficulty breathing or swallowing, swelling of the face, lips, tongue, oral cavity, throat or eyes.

• you have had a reaction to heparin that caused a severe drop in the number of your clotting cells (platelets) within the last 100 days
• you have antibodies against enoxaparin in your blood
• you are bleeding heavily or have a condition with a high risk of bleeding, such as:

o stomach ulcer, recent surgery of the brain or eyes, or recent bleeding stroke.

• you are using Clexane to treat blood clots and are going to have within 24 hours: o a spinal or lumbar puncture o an operation with epidural or spinal anaesthesia.

Do not use Clexane if any of the above apply to you. If you are not sure, talk to your doctor or pharmacist befo re using Clexane.

Warnings and precautions

Clexane should not be interchanged with other ‘low molecular weight heparins’ such as nadroparin, tinzaparin or dalteparin. 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 Clexane if:

• you have ever had a reaction to heparin that caused a severe drop in the number of your clotting cells (platelets)
• you have had a heart valve fitted
• you have endocarditis (an infection of the inner lining of the heart)
• you have a 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 levels of potassium in your blood (this may be checked with a blood test)
• you are currently using medicines which affect bleeding (see section 2, ‘Other medicines and Clexane’)
• you have any problem with your spine or you have had spinal surgery.

If any of the above apply to you (or you are not sure), talk to your doctor or pharmacist before using Clexane.

For patients receiving doses higher than 210mg/day, this medicine contains more than 24mg sodium (main component of cooking/table salt) in each dose. This is equivalent to 1.2% of the recommended maximum daily intake of sodium for an adult.

Tests and checks

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

Giving yourself an injection of Clexane

If you are able to give Clexane 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 Clexane

• 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 stomach 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 Clexane: Preparing the injection site

• 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.

• 2) Wash your hands. Cleanse (do not rub) that you will inject with an alcohol swab and water.

  the area or soap

  
  

• 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) 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).

• 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.

• 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.

• 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) 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) 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.

  
  

• 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.

• 4) Remove the needle from the injection site by pulling it straight out. You can now let go of the skin fold.

When you have finished

• 1) To avoid bruising, do not rub the injection site after you have injected yourself.

• 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.

Changing anticoagulant medicine

• Changing from Clexane to blood thinners called vitamin-K antagonists (such as warfarin) Your doctor will ask you to have blood tests called INR and tell you when to stop Clexane.
• Changing from blood thinners called vitamin-K antagonists (such as warfarin) to Clexane Stop taking the vitamin-K antagonist. Your doctor will ask you to have blood tests called INR and tell you when to start Clexane.
• Changing from Clexane to treatment with direct oral anticoagulants

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

• Changing from treatment with direct oral anticoagulant to Clexane

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

If you use more Clexane than you should

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

If you forget to use Clexane

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 Clexane

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

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

4. POSSIBLE SIDE EFFECTS

o cramping pain, redness, warmth, or swelling in one of your legs – these are symptoms of deep vein thrombosis

o 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.

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

Giving yourself an injection of Enoxaparin If you are able to give Enoxaparin 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 Enoxaparin

• 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 stomach 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 Clexane: Preparing the injection site

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.

• 2) Wash your hands. Cleanse (do not rub) that you will inject with an alcohol swab and water.

  the area or soap

  
  

• 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) 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).

• 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.

• 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.

• 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) 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) 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.

  
  

• 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.

• 4) Remove the needle from the injection site by pulling it straight out. You can now let go of the skin fold.

When you have finished

• 1) To avoid bruising, do not rub the injection site after you have injected yourself.

• 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.

Changing anticoagulant medicine

• Changing from Enoxaparin to blood thinners called vitamin-K antagonists (such as warfarin) Your doctor will ask you to have blood tests called INR and tell you when to stop Enoxaparin.
• Changing from blood thinners called vitamin-K antagonists (such as warfarin) to Enoxaparin Stop taking the vitamin-K antagonist. Your doctor will ask you to have blood tests called INR and tell you when to start Enoxaparin.
• Changing from Enoxaparin to treatment with direct oral anticoagulants

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

• Changing from treatment with direct oral anticoagulant to Enoxaparin

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

If you use more Enoxaparin than you should

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

If you forget to use Enoxaparin

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 Enoxaparin

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

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