How to use Clexane

Having this medicine
• Before you use Clexane your doctor or nurse may carry out a blood test
• While you are in hospital your doctor or nurse will normally give you
Clexane. This is because it needs to be given as an injection
• When you go home you may need to continue to use Clexane and give it to
yourself (see below instructions on how to do this)
• Clexane is usually given by injection underneath the skin (subcutaneous)
If you are not sure why you are receiving Clexane or have any questions
about how much Clexane is being given to you, speak to your doctor,
pharmacist or nurse.
How much will be given to you
• Your doctor will decide how much to give you. The amount of Clexane
given to you will depend on the reason it is being used
• If you have problems with your kidneys, you may be given a smaller
amount of Clexane

If you are aged 75 years or older
• Your doctor or nurse will give you injections of Clexane under your skin
(subcutaneous injection)
• The usual dose is 0.75mg for every kilogram of your weight, every 12
hours
• The maximum amount of Clexane given for the first two injections is 75mg
For patients having an operation called Percutaneous Coronary
Intervention (PCI)
• Depending on when you were last given Clexane, your doctor may decide
to give an additional dose of Clexane before a PCI operation. This is by
injection into your vein (intravenous using Clexane Multidose Vial or
60, 80 or 100mg Pre-filled syringes)
3) Stop blood clots forming in the tubes of your dialysis machine
The usual dose is 1 mg for every kilogram of your weight
Clexane 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 0.5 to 1mg for every kilogram of
your weight if necessary

1) Treating blood clots that are in your blood

a) Unstable angina
• The usual amount is 1mg for every kilogram of weight, every 12 hours
• Clexane will usually be given for 2 to 8 days. Your doctor will normally
ask you to take aspirin as well

1) Wash your hands and the area that you will inject with soap and water.
Dry them.

2) 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.

How to give 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.

8) Remove the needle by pulling it straight out. You can now let go of the
skin fold.

9) Drop the used syringe - needle first - into the sharps bin provided. Close
the container lid tightly and place the container out of reach of children.
When the container is full, give it to your doctor or home care nurse
for disposal. Do not put it in the household rubbish.
3) 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.
Remember: Do not inject yourself within 5 centimetres 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 were last injected.
4) Carefully pull off the needle cap from the Clexane syringe. Throw away
the cap. The syringe is pre-filled and ready to use.

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

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).

Blood Tests
Using Clexane may affect the results of some blood tests. If you are going to
have a blood test, it is important to tell your doctor you are having Clexane.

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

Before injecting yourself with Clexane
b) After an operation or long periods of bedrest due to illness
• The usual dose is 20mg or 40mg each day. The dose will depend on
how likely you are to develop a clot
• If you have a low to medium risk of getting a clot, you will be given
20mg of Clexane each day. If you are going to have an operation, your
first injection will usually be given 2 hours before your operation
• If you have a higher risk of getting a clot, you will be given 40mg each
day. If you are going to have an operation, your first injection will usually
be given 12 hours before your operation
• If you are bedridden due to illness, you will be normally be given 40mg
of Clexane each day for 6 to 14 days

7) Press down on the plunger with your finger. This will send the medication
into the fatty tissue of the stomach. Make sure you hold the skin fold
throughout the injection.

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

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.



Frequency unknown

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.



Frequency unknown
• 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.



Frequency unknown
• Feeling tired, faint, dizzy, having pale skin.
These could be symptoms of anaemia.
• You notice yellowing of your skin or eyes and your urine becomes darker
in colour. This could be a liver problem.
Other side effects that you should discuss with your nurse or doctor if
you are concerned about them:
Very common (affects more than 1 in 10 people)
• Changes in the results of blood tests done to check how your liver is
working. These usually go back to normal after you stop having Clexane.
Rare (affects less than 1 in a 1000 people)
• Changes in the potassium levels 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.
Frequency unknown
• If Clexane is used for a long period of time (more than 3 months), it may
increase the risk of you getting a condition called ‘osteoporosis’. This is
when your bones are more likely to break
• Headache
• Hair loss

What Clexane is and what it is used for

The name of your medicine is either Clexane 20mg/0.2ml Syringe/ Clexane
40mg/0.4ml Syringe/ Clexane 60mg/0.6ml Syringe/ Clexane 80mg/0.8ml
Syringe/ Clexane 100mg/1ml Syringe (called Clexane in this leaflet). 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)

Clexane is a registered trademark of Aventis Pharma SA.

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

Page 1

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.

c) After you have had a heart attack
Clexane can be used for two different types of heart attack called NSTEMI or
STEMI.
The amount of Clexane given to you will depend on your age and the kind of
heart attack you have had.

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.

i) NSTEMI type of heart attack
• The usual amount is 1mg for every kilogram of weight, every 12 hours
• Clexane will usually be given for 2 to 8 days. Your doctor will normally ask
you to take aspirin as well
ii) STEMI type of heart attack
If you are under 75 years old
• 30mg of Clexane will be given as an injection into your vein (intravenous
injection using Clexane Multidose Vial or 60, 80 or 100mg Pre-filled
syringes)
• At the same time, you will also be given Clexane as an injection under
your skin (subcutaneous injection). The usual dose is 1mg for every
kilogram of your weight.
• Then you will be given 1mg for every kilogram of your weight every 12
hours after that
• The maximum amount of Clexane given for the first two injections is 100mg

How to use Clexane

Having this medicine
• Before you use Clexane your doctor or nurse may carry out a blood test
• While you are in hospital your doctor or nurse will normally give you
Clexane. This is because it needs to be given as an injection
• When you go home you may need to continue to use Clexane and give it to
yourself (see below instructions on how to do this)
• Clexane is usually given by injection underneath the skin (subcutaneous)
If you are not sure why you are receiving Clexane or have any questions
about how much Clexane is being given to you, speak to your doctor,
pharmacist or nurse.
How much will be given to you
• Your doctor will decide how much to give you. The amount of Clexane
given to you will depend on the reason it is being used
• If you have problems with your kidneys, you may be given a smaller
amount of Clexane

If you are aged 75 years or older
• Your doctor or nurse will give you injections of Clexane under your skin
(subcutaneous injection)
• The usual dose is 0.75mg for every kilogram of your weight, every 12
hours
• The maximum amount of Clexane given for the first two injections is 75mg
For patients having an operation called Percutaneous Coronary
Intervention (PCI)
• Depending on when you were last given Clexane, your doctor may decide
to give an additional dose of Clexane before a PCI operation. This is by
injection into your vein (intravenous using Clexane Multidose Vial or
60, 80 or 100mg Pre-filled syringes)
3) Stop blood clots forming in the tubes of your dialysis machine
The usual dose is 1 mg for every kilogram of your weight
Clexane 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 0.5 to 1mg for every kilogram of
your weight if necessary

1) Treating blood clots that are in your blood

a) Unstable angina
• The usual amount is 1mg for every kilogram of weight, every 12 hours
• Clexane will usually be given for 2 to 8 days. Your doctor will normally
ask you to take aspirin as well

1) Wash your hands and the area that you will inject with soap and water.
Dry them.

2) 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.

How to give 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.

Page 2

8) Remove the needle by pulling it straight out. You can now let go of the
skin fold.

9) Drop the used syringe - needle first - into the sharps bin provided. Close
the container lid tightly and place the container out of reach of children.
When the container is full, give it to your doctor or home care nurse
for disposal. Do not put it in the household rubbish.
3) 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.
Remember: Do not inject yourself within 5 centimetres 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 were last injected.
4) Carefully pull off the needle cap from the Clexane syringe. Throw away
the cap. The syringe is pre-filled and ready to use.

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

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

Before injecting yourself with Clexane
b) After an operation or long periods of bedrest due to illness
• The usual dose is 20mg or 40mg each day. The dose will depend on
how likely you are to develop a clot
• If you have a low to medium risk of getting a clot, you will be given
20mg of Clexane each day. If you are going to have an operation, your
first injection will usually be given 2 hours before your operation
• If you have a higher risk of getting a clot, you will be given 40mg each
day. If you are going to have an operation, your first injection will usually
be given 12 hours before your operation
• If you are bedridden due to illness, you will be normally be given 40mg
of Clexane each day for 6 to 14 days

7) Press down on the plunger with your finger. This will send the medication
into the fatty tissue of the stomach. Make sure you hold the skin fold
throughout the injection.

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




• The usual dose is 1.5mg for every kilogram of your weight, each day
• Clexane will usually be given for at least 5 days
2) Stopping blood clots forming in your blood in the following
situations:

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 1 mg/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 0.5 mg/kg (50 IU/kg) for double vascular access or 0.75 mg/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).

Revision date: 14/10/2014

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 30-50 ml/min) or mild renal impairment (creatinine clearance 50-80 ml/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.
