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.
Before injecting yourself with Clexane
 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 abdomen 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
 Decide where you are going to inject the medicine. Change the place where you
inject each time from the right to the left side of your stomach. Clexane should be
injected just under the skin on your stomach, but not too near the belly button or
any scar tissue (at least 5 cm away from these)

Instructions on injecting yourself with Clexane:

4. Possible side-effects

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

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.

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.

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.

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.

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.

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.

Make sure you hold the skin fold throughout the injection.
6) Hold the syringe so that the needle is pointing downwards (vertically at a 90º angle).
Insert the full length of the needle into the skin fold.
7) Press down on the plunger with your thumb.
This will send the medication into the fatty tissue of the stomach. Make sure you
hold the skin fold throughout the injection.

8) Remove the needle by pulling it straight out.
You can now let go of the skin fold.
To avoid bruising, do not rub the injection site after you have injected yourself.
9) Drop the used syringe - the needle end 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.
If you have too much or too little Clexane
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.

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

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.

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.

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.

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.

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.

Make sure you hold the skin fold throughout the injection.
6) Hold the syringe so that the needle is pointing downwards (vertically at a 90º angle).
Insert the full length of the needle into the skin fold.
7) Press down on the plunger with your thumb.
This will send the medication into the fatty tissue of the stomach. Make sure you
hold the skin fold throughout the injection.

8) Remove the needle by pulling it straight out.
You can now let go of the skin fold.
To avoid bruising, do not rub the injection site after you have injected yourself.
9) Drop the used syringe - the needle end 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.
If you have too much or too little Clexane
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.

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

1. What Clexane is and what it is used for

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.

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)
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.

 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.

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

Before injecting yourself with Clexane
 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 abdomen 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
 Decide where you are going to inject the medicine. Change the place where you
inject each time from the right to the left side of your stomach. Clexane should be
injected just under the skin on your stomach, but not too near the belly button or
any scar tissue (at least 5 cm away from these)

Instructions on injecting yourself with Clexane:

4. Possible side-effects

following side-effects:
Very common (affects more than 1 in 10 people)
• Bleeding a lot from a wound.

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.

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

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.

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.

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 20 mg (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 40 mg (4,000 IU) daily by subcutaneous
injection with the initial dose administered approximately 12 hours before surgery.

(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 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).

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.

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.
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.
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
