1.  hat Fragmin is and what it is used for
Fragmin is a solution for injection. Its active ingredient is
dalteparin sodium.
Fragmin belongs to a group of medicines called low
molecular weight heparins or antithrombotics, which help
prevent the formation of blood clots by thinning the blood.
Fragmin is used to treat blood clots (venous
thromboembolism) and to prevent their recurrence.
Venous thromboembolism is a condition where blood
clots develop in the legs (deep vein thrombosis) or the
lungs (pulmonary embolism), e.g. after surgery, prolonged
bed-rest or in patients with certain types of cancer.
Fragmin is also used to treat a condition known as
unstable coronary artery disease. In coronary artery
disease the coronary arteries (blood vessels to the heart)
are furred up and narrowed by patches of fatty deposits.
Unstable coronary artery disease means that a furred
up bit of the artery has ruptured and a clot has formed
on it, reducing the flow of blood to the heart. Patients
with this condition may be more likely to go on to have a
heart attack without treatment with blood thinning drugs
such as Fragmin.
Ask your doctor if you are unsure why you have been given

2.  hat you need to know before you are
given or use Fragmin
You should not be given or use Fragmin

•  you are allergic (hypersensitive) to the active
ingredient dalteparin sodium or a similar product or
any of the other ingredients of this medicine (listed in
section 6).
•  you have an active stomach ulcer or ulcer of the
duodenum (small intestine).
•  you have suffered from a brain haemorrhage (bleeding

bleed more easily (e.g. haemophilia, liver failure). Ask
your doctor if you are unsure.
•  you have a condition called septic endocarditis (an
infection and inflammation of the lining of the heart and
heart valves). Your doctor will have told you if you have
•  you have had a condition called “heparin-induced
thrombocytopenia” (a decrease in the number of clotting
cells (platelets) in your blood caused by heparin, which
may cause you to bruise and bleed more easily). Your
doctor will have told you if you have this.
•  you have an injury to, or have had an operation
involving your spine, head, eyes or ears.
If you are receiving Fragmin to treat blood clots, you should
not have a local, spinal or epidural anaesthetic.

experience; there are limited data from clinical trials, which
will help your doctor calculate the dose of Fragmin.

Other medicines and Fragmin

Tell your doctor, pharmacist or nurse if you are taking, have
recently taken or are planning to take or use any other
medicines. This includes medicines that you have bought
for yourself.
Some medicines can affect the way Fragmin works,
or Fragmin itself can reduce the effectiveness of other
medicines taken at the same time.
Medicines that increase the effect of Fragmin include:
Those used to thin your blood: (e.g. aspirin, dipyridamole,
glycoprotein receptor antagonists and warfarin).
Medicines called non-steroidal anti-inflammatory drugs
(NSAIDs) used to reduce pain and inflammation (e.g.
Some medicines for gout (e.g. sulfinpyrazone and
Etacrynic acid (a water retention tablet (diuretic)).
Solutions given to increase the blood volume (e.g.
Medicines known as cytostatics (used in cancer
Thrombolytic medications for treating transmural heart
attack (e.g. TPA-tissue plasminogen activator).
Medicines that can reduce the effect of Fragmin, include:
• Those for allergy and hay fever (e.g. antihistamines).
Those used for heart or circulation problems (e.g.
digoxin or digitoxin).

Antibiotics known as tetracyclines which are used to
treat bacterial infections.
• Vitamin C (e.g. some vitamin supplements).
Other medicines that may interfere with Fragmin include:
• Those used to treat angina (intravenous
• Antibiotics such as high dose penicillin which are
used to treat bacterial infections
• Anti-malarials (e.g. quinine)
• Tobacco smoking.
Please note that if you are being treated with Fragmin for
unstable coronary artery disease your doctor may adjust
your dose of aspirin accordingly.
Please tell your doctor or pharmacist if you are taking
or have recently taken any other low molecular weight
heparins or anti-thrombotics.

Pregnancy and breast-feeding

Fragmin has not been found to cause harmful effects
during pregnancy. The possibility of harm to the baby
appears remote. Tell your doctor if you are pregnant and
they will advise you.
Fragmin is not recommended for the prevention of blood
clots on artificial heart valves during pregnancy.
If you are receiving Fragmin to treat blood clots, you should
not have a local, spinal or epidural anaesthetic.
Ask your doctor or pharmacist for advice before being
given or using this medicine whilst breast-feeding.

Fragmin does not affect the ability to drive and operate

3. How Fragmin is given to you
Your medicine will usually be administered by a doctor
or nurse or you may be shown how to give the injection
yourself at home (See Section on How to Inject Fragmin).
The amount of Fragmin you receive will depend on your
body weight.
Fragmin is given as a single, once daily, subcutaneous
injection, which means it is injected beneath the skin. It is
usually injected into a skin fold in your abdomen (stomach),
or the outer aspects of your thigh. It should not be injected
into your muscles.

Use in adults and the elderly
To treat blood clots (venous thromboembolism)
• Deep Vein Thrombosis
The usual dose of Fragmin used to treat deep vein
thrombosis is 200 IU (units) for every kilogram you weigh,
given once a day. Your doctor will select the dose which is
appropriate for you based on your bodyweight.
The following table shows the dose you will receive
depending on your body weight:
Body weight (kg)

Dose (IU)

< 46








≥ 83


Abbreviations: IU = International Unit
The maximum daily dose is 18,000 IU.
Fragmin can be used together with other blood thinning
medicines known as Vitamin K antagonists. Should this be
desired, a minimum of five days would be required.
To treat blood clots (venous thromboembolism) in
certain types of cancer and prevent recurrence
The usual dose used to treat venous thromboembolism in
cancer is 200 IU (international units) for every kilogram you
weigh (see previous table) once daily during the first month
after a thromboembolic event (blood clot), followed by
150 IU for every kilogram you weigh (during months 2-6).
Dose of Fragmin during months 2-6
Body Weight (kg)

This treatment course is not recommended for patients
weighing less than 40 kg.
The maximum daily dose is 18,000 IU. The recommended
duration of treatment is 6 months. If you are suffering
from severe kidney disease or a decreased platelet
count (clotting cells) caused by chemotherapy or another
condition with an elevated bleeding risk, your doctor will
adjust this dose accordingly.
In some cases of decreased platelet count (clotting cells),
your doctor may interrupt your treatment with Fragmin for a
short period.
Medical staff may take blood samples during your
treatment to monitor the effects of Fragmin.
• Unstable Coronary Artery Disease
The usual dose used to treat unstable coronary artery
disease is 120 IU (units) for every kilogram you weigh,
given every 12 hours.
The maximum dose in a 12 hour period is 10,000 IU (units).

If your doctor has recommended a special procedure to
restore the blood supply to your heart (angiography or
coronary artery surgery), it may be necessary to continue
to administer Fragmin for up to 45 days. In this case, the
typical dose for adults, including elderly patients should be
either 5,000 IU (units) (women less than 80 kg and men
less than 70 kg) or 7,500 IU (women 80 kg and above and
men 70 kg and over) every 12 hours.

Step 3:

Pick up the syringe, grasp the tip of the plastic needle
catcher and bend it away from the shield.
Remove the grey rubber cover by pulling
it straight off. You will notice an air bubble
in the syringe. It is supposed to be there
and you can just ignore it. It is important
not to press the plunger just yet as some
of the medicine may be lost.

Step 4:

Hold the syringe in one hand and with the other hand,
gently pinch a fold of skin with its fatty tissue (see the
shaded areas above) between your thumb and index
finger. This will be the injection site.

What Fragmin contains.

The active ingredient in Fragmin is dalteparin sodium.
Each pre-filled syringe provides a single dose of 7,500 IU
(International units) of dalteparin sodium.
The other ingredients are water for injections, either
sodium hydroxide or hydrochloric acid (to balance the
acidity of the injection).

What Fragmin looks like and contents of the

Fragmin is available as a clear, colourless or straw- coloured
solution, in pre-filled single dose syringes, each containing
0.3 ml of dalteparin sodium solution. Each box contains
10 disposable syringes.
