1. what clexane is and what it is used for
Clexane contains a medicine called enoxaparin sodium. This belongs to a group of medicines called Low Molecular Weight Heparins.
Clexane works in two ways.
-
1) Stopping existing blood clots from getting any bigger. This helps your body to break them down and stop them causing you harm.
-
2) Stopping blood clots forming in your blood.
Clexane can be used to:
- Treat blood clots that are in your blood
- Stop blood clots forming in your blood in the following situations:
- Unstable angina (where not enough blood gets to your heart)
- After an operation or long periods of bed rest due to illness
- After you have had a heart attack
- Stop blood clots forming in the tubes of your dialysis machine (used for people with kidney problems)
2. before you use clexane
Do not have this medicine and tell your doctor, pharmacist or nurse if:
- You are allergic (hypersensitive) to enoxaparin sodium or any of the other ingredients of Clexane (listed in Section 6: Further information)
Signs of an allergic reaction include: a rash, swallowing or breathing problems, swelling of your lips, face, throat or tongue
- You are allergic to heparin or other Low Molecular Weight Heparins such as tinzaparin or dalteparin
- You have a problem with bruising or bleeding too easily
- You have an ulcer in your stomach or gut (intestine)
- You have had a stroke caused by bleeding in the brain
- You have an infection in your heart
- You are using the medicine called heparin to treat blood clots
Do not have this medicine if any of the above apply to you. If you are not sure, talk to your doctor, pharmacist or nurse before having Clexane.
Take special care with Clexane
Check with your doctor or pharmacist or nurse before using this medicine if:
- You have high blood pressure
- You have kidney problems
- You have had a heart valve fitted
- You have ever had bruising and bleeding caused by the medicine ‘heparin’
- You have ever had a stroke
- You have ever had a stomach ulcer
- You have recently had an operation on your eyes or brain
- You are a diabetic or have an illness known as ‘diabetic retinopathy’ (problems with the blood vessels in the eye caused by diabetes)
- You have any problems with your blood
- You are underweight or overweight
- You are elderly (over 65 years old) and especially if you are aged over 75 years old
If you are not sure if any of the above applies to you, talk to your doctor or pharmacist or nurse before using Clexane.
Taking or using other medicines
Please tell your doctor, pharmacist or nurse if you are taking or have recently taken any other medicines. This includes medicines you buy without a prescription, including herbal medicines. This is because Clexane can affect the way some other medicines work. Also some medicines can affect the way Clexane works.
In particular, do not have this medicine and tell your doctor if:
- You are using the medicine called heparin to treat blood clots
Tell your doctor if you are taking any of the following medicines:
- Warfarin – used for thinning the blood
- Aspirin, dipyridamole, clopidogrel or other medicines – used to stop blood clots forming
- Dextran injection – used as a blood replacer
- Ibuprofen, diclofenac, ketorolac or other medicines – used to treat pain and swelling in arthritis and other illnesses
- Prednisolone, dexamethasone or other medicines – used to treat asthma, rheumatoid arthritis and other conditions
- Water tablets (diuretics) such as spironolactone, triamterene or amiloride. These may increase the levels of potassium in your blood when taken with Clexane
Your doctor may change one of your medicines or take regular blood tests to check that taking these medicines with Clexane is not causing you any harm.
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 Clexane. Tell also your doctor if you have any problem with your spine or if you have ever had spinal surgery.
Pregnancy and breast-feeding
Talk to your doctor before you use this medicine if you are pregnant, might become pregnant, or think you may be pregnant.
You should not use this medicine if you are pregnant and have a mechanical heart valve as you may be at increased risk of developing blood clots. Your doctor should discuss this with you.
You should not breast-feed whilst using Clexane. If you are planning to breast-feed, talk to your doctor, pharmacist or nurse.
Ask your doctor or pharmacist for advice before taking any medicine if you are pregnant or breastfeeding.
3. how to use clexane
if clexane is used for a long period of time, it may increase the risk of you getting a condition called ‘osteoporosis’. this is when your bones are more likely to break.
5. how to store and dispose of clexane
KEEP ALL MEDICINES OUT OF THE SIGHT AND REACH OF CHILDREN.
Do not store above 25°C. Do not refrigerate or freeze.
The expiry date can be found on the syringe blister container and on the box. It is given as “EXP” followed by the month and year. Clexane should not be used after the end of that month. If you are not sure when this is check with your doctor, pharmacist or nurse.
If your doctor tells you to stop taking the medicine, please take them back to the pharmacist for safe disposal. Only keep the medicine if your doctor tells you to.
If the medicine becomes discoloured or shows any signs of deterioration, you should seek the advice of your pharmacist.
Medicines should not be disposed of via wastewater or household waste. If you are using this medicine at home you will be given a container (a sharps bin) to use for disposal.

4. POSSIBLE SIDE-EFFECTS
Like all medicines, Clexane can cause side-effects, although not everybody gets them.
Tell a nurse or doctor or go to hospital straight away if you notice any of the following side-effects:
Very common (affects more than 1 in 10 people)
- Bleeding a lot from a wound.
Common (affects 1 to 10 people in a 100)
- A painful rash of dark red spots under the skin which do not go away when you put pressure on them. You may also notice pink patches on your skin. These are more likely to appear in the area you have been injected with Clexane.
Uncommon (affects 1 to 10 people in a 1,000)
- 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 inside your stomach.
Rare (affects less than 1 in a 1000 people)
- If you have an allergic reaction. The signs may include: a rash, swallowing or breathing problems, swelling of your lips, face, throat or tongue.
- If you have had a spinal puncture or a spinal anaesthetic and notice tingling, numbness and muscular weakness, particularly in the lower part of your body. Also if you lose control over your bladder or bowel (so you cannot control when you go to the toilet).
Tell a nurse or doctor as soon as possible if you notice any of the following side-effects:
Common (affects 1 to 10 people in a 100)
- You bruise more easily than usual. This could be because of a blood problem (thrombocytopenia).
- You have pain, swelling or irritation in the area you have been injected with Clexane. This normally gets better after a few days.
Rare (affects less than 1 in a 1000 people)
- If you have a mechanical heart valve, treatment with Clexane might not be sufficient to prevent blood clots. You may notice that you have difficulty breathing, tiredness or difficulty exercising, chest pain, numbness, feeling sick or loss of consciousness. This could be due to a blood clot on the heart valve.

4.2 Posology and method of administration
Adults:
Prophylaxis of venous thromboembolism:
In patients with a low to moderate risk of venous thromboembolism the recommended dosage is 20mg (2,000 IU) once daily by subcutaneous injection for 7 to 10 days, or until the risk of thromboembolism has diminished. In patients undergoing surgery, the initial dose should be given approximately 2 hours pre-operatively. In patients with a higher risk, such as in orthopaedic surgery, the dosage should be 40mg (4,000 IU) daily by subcutaneous injection with the initial dose administered approximately 12 hours before surgery.
Prophylaxis of venous thromboembolism in medical patients:
The recommended dose of enoxaparin sodium is 40mg (4,000 IU) once daily by subcutaneous injection. Treatment with enoxaparin sodium is prescribed for a minimum of 6 days and continued until the return to full ambulation, for a maximum of 14 days.
Treatment of venous thromboembolism:
Clexane should be administered subcutaneously as a single daily injection of 1.5mg/kg (150 IU/kg). Clexane treatment is usually prescribed for at least 5 days and until adequate oral anticoagulation is established.

(1) Not to be given for the first two doses – (maximum 100mg for the first two doses only, followed by 1mg/kg dosing for the remaining doses)
Please be aware that in some cases it is not possible to achieve an exact dose due to the graduations on the syringe and so some of the volumes recommended in this table have been rounded up to the nearest graduation.
When administered in conjunction with a thrombolytic (fibrin specific or non-fibrin specific) enoxaparin sodium should be given between 15 minutes before and 30 minutes after the start of fibrinolytic therapy. All patients should receive acetylsalicylic acid (ASA) as soon as they are identified as having STEMI and maintained under (75 to 325mg once daily) unless contraindicated.
The recommended duration of enoxaparin sodium treatment is 8 days or until hospital discharge, whichever comes first.
For patients managed with Percutaneous Coronary Intervention (PCI): If the last enoxaparin sodium SC administration was given less than 8 hours before balloon inflation, no additional dosing is needed. If the last SC administration was given more than 8 hours before balloon inflation, an IV bolus of 0.3mg/kg of enoxaparin sodium should be administered.
Prevention of extracorporeal thrombus formation during haemodialysis:
A dose equivalent to 1mg/kg (100 IU/kg) introduced into the arterial line at the beginning of a dialysis session is usually sufficient for a 4 hour session. If fibrin rings are found, such as after a longer than normal session, a further dose of 0.5 to 1mg/kg (50 to 100 IU/kg) may be given. For patients at a high risk of haemorrhage the dose should be reduced to 0.5mg/kg (50 IU/kg) for double vascular access or 0.75mg/kg (75 IU/kg) for single vascular access.
Elderly:
For treatment of acute ST-segment Elevation Myocardial Infarction in elderly patients >75 years of age, do not use an initial IV bolus. Initiate dosing with 0.75mg/kg SC every 12 hours (maximum 75mg for the first two doses only, followed by 0.75mg/kg dosing for the remaining doses).
For other indications, no dosage adjustments are necessary in the elderly, unless kidney function is impaired (see also section 4.2 Posology and method of administration: Renal impairment ; section 4.4 Special warnings and precautions for use: Haemorrhage in the elderly; Renal impairment, and Monitoring; section 5.2 Pharmacokinetic properties).

Children : Not recommended, as dosage not established.
Renal impairment: (See also section 4.4 Special warnings and precautions for use: Renal impairment and Monitoring ; section 5.2 Pharmacokinetic properties).
Severe renal impairment:
A dosage adjustment is required for patients with severe renal impairment (creatinine clearance < 30ml/min), according to the following tables, since enoxaparin sodium exposure is significantly increased in this patient population:
Dosage adjustments for therapeutic dosage range
Standard dosing | Severe renal impairment |
1mg/kg SC twice daily | 1mg/kg SC once daily |
1.5mg/kg SC once daily | 1mg/kg SC once daily |
For treatment of acute STEMI in patients <75 years of age | |
30mg-single IV bolus plus a 1mg/kg SC dose followed by 1mg/kg twice daily. (Max 100mg for each of the first two SC doses) | 30mg-single IV bolus plus a 1mg/kg SC dose followed by 1mg/kg once daily. (Max 100mg for first SC dose only) |
For treatment of acute STEMI in elderly patients >75 years of age | |
0.75mg/kg SC twice daily without initial bolus. (Max 75mg for each of the first two SC doses) | 1mg/kg SC once daily without initial bolus. (Max 100mg for first SC dose only) |
Dosage adjustments for prophylactic dosage ranges
Standard dosing | Severe renal impairment |
40mg SC once daily | 20mg SC once daily |
20mg SC once daily | 20mg SC once daily |
The recommended dosage adjustments do not apply to the haemodialysis indication.
Moderate and mild renal impairment:
Although no dosage adjustments are recommended in patients with moderate renal impairment (creatinine clearance 30–50ml/min) or mild renal impairment (creatinine clearance 50–80ml/min), careful clinical monitoring is advised.
Hepatic impairment: In the absence of clinical studies, caution should be exercised.
Body weight:
No dosage adjustments are recommended in obesity or low body weight (see also section 4.4 Special warnings and precautions for use: Low body weight and Monitoring ; section 5.2 Pharmacokinetic properties).
Clexane is administered by subcutaneous injection for the prevention of venous thromboembolic disease, treatment of deep vein thrombosis or for the treatment of unstable angina, non-Q-wave myocardial infarction and acute ST elevation myocardial infarction (STEMI); through the arterial line of a dialysis circuit for the prevention of thrombus formation in the extra-corporeal circulation during haemodialysis; and via intravenous (bolus) injection through an intravenous line only for the initial dose of acute STEMI indication and before PCI when needed. It must not be administered by the intramuscular route.
To avoid accidental needle stick after injection, the prefilled syringes are fitted with an automatic safety device.
Subcutaneous injection technique
The prefilled disposable syringe is ready for immediate use. Clexane should be administered when the patient is lying down by deep subcutaneous injection. The administration should be alternated between the left and right anterolateral or posterolateral abdominal wall. The whole length of the needle should be introduced vertically into a skin fold held between the thumb and index finger. The skin fold should not be released until the injection is complete.
Once the plunger is fully pressed down the safety device is activated automatically. This protects the used needle.
Note: The plunger has to be pressed down all the way for the safety device to be activated. Do not rub the injection site after administration.
Intravenous (Bolus) Injection Technique (for acute STEMI indication only):
For intravenous injection, either the Multidose Vial or 60mg, 80mg or 100mg prefilled syringes can be used. Enoxaparin sodium should be administered through an intravenous line. It should not be mixed or co-administered with other medications. To avoid the possible mixture of enoxaparin sodium with all other drugs, the intravenous access chosen should be flushed with a sufficient amount of saline or dextrose solution prior to and following the intravenous bolus administration of enoxaparin sodium to clear the port of drug. Enoxaparin sodium may be safely administered with normal saline solution (0.9%) or 5% dextrose in water.
- Initial 30mg bolus
For the initial 30mg bolus, using an enoxaparin sodium graduated prefilled syringe (60, 80 or 100mg), expel the excessive volume to retain only 30mg (0.3ml) in the syringe. The 30mg dose can then be directly injected into an injection site in the intravenous line.
- Additional bolus for PCI when last SC administration was given more than 8 hours before balloon insertion
For patients being managed with Percutaneous Coronary Intervention (PCI), an additional IV bolus of 0.3mg/kg is to be administered if last SC administration was given more than 8 hours before balloon inflation (see section 4.2 Posology and method of administration: Treatment of acute ST-segment Elevation Myocardial Infarction).
In order to assure the accuracy of the small volume to be injected, it is recommended to dilute the drug to 3mg/ml.
To obtain a 3mg/ml solution, using a 60mg enoxaparin sodium prefilled syringe, it is recommended to use a 50ml infusion bag (i.e. using either normal saline solution (0.9%) or 5% dextrose in water) as follows:
Withdraw 30ml from the infusion bag with a syringe and discard the liquid. Inject the complete contents of the 60mg enoxaparin sodium prefilled syringe into the 20ml remaining in the bag. Gently mix the contents of the bag. Withdraw the required volume of diluted solution with a syringe for administration into the intravenous line (using an appropriate injection site or port).
After dilution is completed, the volume to be injected can be calculated using the following formula [Volume of diluted solution (ml) = Patient weight (kg) x 0.1] or using the table below. It is recommended to prepare the dilution immediately before use and to discard any remaining solution immediately after use.
Volume to be injected through intravenous line after dilution is completed
Weight | Required dose (0.3mg/kg) | Volume to inject when diluted to a final concentration of 3mg/ml | Weight | Required dose (0.3mg/kg) | Volume to inject when diluted to a final concentration of 3mg/ml |
