1. What Fragmin is and what it is used for

Fragmin is an anticoagulant medicine containing dalteparin sodium. Dalteparin sodium is a low-molecular-weight heparin. The anticoagulant effect of dalteparin is related to its ability to enhance inhibition of factor Xa and thrombin.

Fragmin is indicated for use in adult patients aged over 18 years for:

• Treatment of acute deep vein thrombosis.
• Unstable coronary artery disease (e.g. rest angina, myocardial infarction without Q wave).
• Long-term treatment of symptomatic venous thromboembolic disease (proximal deep vein thrombosis and pulmonary embolism) to reduce recurrence of thromboembolic events in patients with cancer.
• Prevention of blood clotting in extracorporeal circulation, e.g. during hemodialysis and hemofiltration in acute or chronic renal failure.
• Prophylaxis of thromboembolic events associated with surgical procedures.
• Prophylaxis of venous thromboembolism in medically ill, immobilized patients: with congestive heart failure in NYHA class III or IV or acute respiratory failure, acute infection, acute rheumatic disease or acute inflammatory bowel disease, and at least one additional risk factor for deep vein thrombosis, e.g. age over 75 years, obesity, cancer, history of deep vein thrombosis.

Fragmin is indicated for use in children for:

• Treatment of blood clots in veins (venous thromboembolic disease (VTE)) in children and adolescents aged 1 month and older.

2. Important information before using Fragmin

When not to use Fragmin

• if the patient is allergic to dalteparin sodium or another low molecular weight heparin, or unfractionated heparin, or any of the other ingredients of this medicine (listed in section 6);
• confirmed or suspected immune-mediated heparin-induced thrombocytopenia;
• active bleeding, e.g. from the gastrointestinal tract or cerebral vessels;
• severe coagulation disorders;
• acute or subacute bacterial endocarditis;
• recent trauma or surgical procedures involving the central nervous system, eyes and/or ears. Due to the increased risk of bleeding, high doses of dalteparin sodium (used, for example, in the treatment of acute deep vein thrombosis, pulmonary embolism and unstable coronary artery disease) must not be administered to patients undergoing spinal or epidural anaesthesia or other procedures requiring lumbar puncture.

Warnings and precautions
Before starting treatment with Fragmin, discuss the following with your doctor or pharmacist.

• In patients prior to spinal (epidural or intrathecal) anaesthesia or lumbar puncture. Patients receiving anticoagulant medicines such as low molecular weight heparins or heparinoids for prevention of thromboembolic complications are at risk of developing epidural or subdural haematoma, which may result in long-term or permanent paralysis. The risk of such complications is increased with the use of an indwelling epidural catheter for administration of anaesthetic agents, and with concomitant use of drugs affecting haemostasis, such as non-steroidal anti-inflammatory drugs (NSAIDs), platelet inhibitors, and other anticoagulants. Traumatic or repeated epidural or lumbar punctures also appear to increase this risk. Such patients should be closely monitored, with frequent assessment of neurological symptoms and signs. In patients with: thrombocytopenia, platelet function disorders, severe hepatic or renal impairment, untreated or uncontrolled hypertension, or hypertensive or diabetic retinopathy.
• High doses of dalteparin sodium, such as those required for treatment of deep vein thrombosis, pulmonary embolism or unstable coronary artery disease, should be used cautiously in patients who have recently undergone surgery or have other conditions that may increase the risk of bleeding.
• For prophylaxis of thrombosis, insertion or removal of an epidural catheter or spinal catheter should be performed 10–12 hours after the last dose of dalteparin. In patients receiving higher doses of Fragmin (e.g. 100–120 IU/kg body weight every 12 hours or 200 IU/kg body weight once daily), the interval should be at least 24 hours.
• In patients who have received epidural or intrathecal anaesthesia, neurological monitoring should be performed for signs of neurological impairment such as back pain, numbness or weakness in the lower limbs, or disturbances in bowel and bladder function. If such symptoms occur, a nurse or doctor should be notified immediately.
• In patients suspected of having epidural or subdural haematoma, treatment may require surgical decompression of the spinal cord.
• In patients with heart valve prostheses. Prophylactic doses of Fragmin are insufficient to prevent thrombosis on the prosthetic valves in these patients.
• In patients with pulmonary embolism who also have circulatory disturbances, hypotension, or are in shock, due to lack of clinical experience with Fragmin in such cases.
• In patients who develop rapidly progressing or severe thrombocytopenia (platelet count less than 100,000/µl or mm³) during treatment. The doctor should order platelet counts before starting treatment with Fragmin and monitor them regularly during therapy. In all such cases, an in vitro test for platelet antibodies in the presence of unfractionated heparin or low molecular weight heparins is recommended. If the test result is positive or inconclusive, or if such a test has not been performed, the doctor should discontinue treatment with Fragmin.
• In paediatric patients, patients with renal impairment, patients with severe underweight or obesity, pregnant women, or patients at increased risk of bleeding or recurrent thrombosis, the doctor should consider monitoring the anticoagulant effect of dalteparin sodium. The doctor will recommend appropriate tests.
• In patients undergoing long-term dialysis, the doctor will recommend appropriate dose adjustment based on anti-Xa activity testing. In patients undergoing emergency haemodialysis, frequent monitoring of anti-Xa activity is required.
• In patients with unstable coronary artery disease, i.e. unstable angina or non-Q-wave myocardial infarction, in whom full-thickness myocardial infarction has occurred. In these patients, the doctor may recommend thrombolytic treatment (to restore blood flow in a blocked or narrowed blood vessel). Concomitant use of Fragmin and thrombolytic agents increases the risk of bleeding, but this does not mean that Fragmin should be discontinued.
• In patients with unstable coronary artery disease treated long-term with Fragmin, in case of impaired renal function (creatinine concentration >150 µmol/l). In these patients, the doctor may consider reducing the dose.
• In patients with allergy or suspected allergy to latex (natural rubber), or in individuals who may come into contact with the needle cover of the Fragmin pre-filled syringe and who have known or possible latex allergy (natural rubber). The needle cover of the Fragmin pre-filled syringe may contain latex (natural rubber). In individuals with latex hypersensitivity, severe allergic reactions may occur. Due to the risk of haematoma formation, intramuscular injections should be avoided in patients treated with Fragmin at daily doses exceeding 5,000 IU.

Interchangeability with other anticoagulants
Dalteparin should not be used interchangeably (unit for unit) with unfractionated heparin, other low molecular weight heparins, or synthetic polysaccharides. Each of these medicines differs in terms of raw materials, manufacturing process, and physicochemical, biological, and clinical properties, leading to differences in dosing and possibly also in clinical efficacy and safety. Each of these medicines is unique and requires adherence to individual medical recommendations for use.

Children
Fragmin should not be used in neonates below 1 month of age.

Fragmin with other medicines
Tell your doctor or pharmacist about all medicines you are currently taking, have recently taken, or plan to take.
Some medicines may affect the action of Fragmin, and Fragmin may reduce the effectiveness of other medicines taken at the same time.
Thrombolytic treatment (clot-dissolving) or certain medicines affecting blood coagulation may increase the risk of bleeding when used concomitantly with Fragmin:

• aspirin (acetylsalicylic acid);
• platelet aggregation inhibitors (used to reduce platelet aggregation and lower the risk of blood clot formation);
• thrombolytic agents (used to dissolve blood clots);
• non-steroidal anti-inflammatory drugs (NSAIDs) (medicines used to treat inflammatory conditions);
• GP IIb/IIIa receptor antagonists (medicines affecting platelet aggregation, used in the treatment of heart disease);
• vitamin K antagonists and other types of anticoagulants;
• dextran (used in some artificial tears).

Medicines that may increase the effect of Fragmin:

• medicines used to thin the blood (dipyridamole);
• certain medicines used to treat gout (e.g. sulfinpyrazone, probenecid);
• certain diuretics (e.g. ethacrynic acid);
• solutions administered to increase blood volume;
• cytostatic medicines (used in cancer treatment).

Medicines that may decrease the effect of Fragmin:

• medicines used to treat allergies and hay fever (e.g. antihistamines);
• medicines used to treat heart failure and circulatory disorders (e.g. cardiac glycosides such as digoxin, digitoxin);
• tetracycline antibiotics used to treat bacterial infections;
• vitamin C (e.g. contained in vitamin preparations).

Other medicines that may affect the action of Fragmin:

• medicines used to treat angina pectoris (e.g. intravenous nitroglycerin);
• antibiotics such as high-dose penicillins used to treat bacterial infections;
• medicines used for prevention and treatment of malaria (e.g. quinine);
• nicotine taken from smoking or smoking cessation products.

It should be noted that if a patient is being treated with Fragmin for unstable coronary artery disease, the doctor may adjust the dose of acetylsalicylic acid (aspirin) accordingly.
Dosing recommendations in children are based on clinical experience; data from clinical trials are too limited for the doctor to determine an appropriate dose of Fragmin.

Pregnancy, breastfeeding and fertility

If you are pregnant or breastfeeding, think you may be pregnant, or are planning to have a baby, you should consult your doctor or pharmacist before using this medicine.

Pregnancy
This medicine should be used during pregnancy only if absolutely necessary.

Breastfeeding
Small amounts of dalteparin sodium pass into human milk. A risk to breastfed infants cannot be excluded. Fragmin should be used during breastfeeding, taking into account the benefits of breastfeeding for the infant and the benefits of therapy for the mother.

Fertility
There are no data indicating an effect of Fragmin on fertility.

Driving and using machines
Fragmin has no influence on the ability to drive and use machines.

Fragmin contains sodium
Fragmin 2,500 IU anti-Xa/0.2 ml, Fragmin 5,000 IU anti-Xa/0.2 ml,
Fragmin 7,500 IU anti-Xa/0.3 ml, Fragmin 10,000 IU anti-Xa/0.4 ml,
Fragmin 12,500 IU anti-Xa/0.5 ml, Fragmin 15,000 IU anti-Xa/0.6 ml
and Fragmin 18,000 IU anti-Xa/0.72 ml contain less than 1 mmol (23 mg) of sodium per pre-filled syringe, meaning these medicines are considered "sodium-free". Patients on a low-sodium diet and parents of children treated with Fragmin may be informed that these medicines are essentially "sodium-free".
This medicine may be diluted with solutions containing sodium. Inform your doctor if you or your child is on a low-sodium diet.

3. How to use Fragmin

This medicine should always be used according to the instructions given by the doctor or pharmacist. If in doubt,
consult your doctor or pharmacist.
Fragmin is administered subcutaneously, intravenously, or extracorporeally (into the dialysis circuit).
Fragmin must not be administered intramuscularly.
For the treatment of blood clots occurring in the patient's blood, Fragmin is administered subcutaneously.
If the patient is undergoing hemodialysis or hemofiltration (procedures used to clean the blood), Fragmin is administered intravenously or into the dialysis tubing.
Dalteparin may be mixed with isotonic infusion solutions of sodium chloride (9 mg/ml) or glucose (50 mg/ml) in glass bottles and plastic containers.
Dosage and method of administration
Treatment of acute deep vein thrombosis
Fragmin may be administered subcutaneously once or twice daily.
During treatment with Fragmin, concomitant administration of vitamin K antagonists may be initiated. Fragmin should be continued until the levels of vitamin K-dependent coagulation factors (factors II, VII, IX, X) have decreased to therapeutic levels. This usually occurs after approximately 5 days of combined treatment. Outpatient treatment is possible using the same doses as those used in hospital.
Once-daily administration
Dose of 200 IU/kg body weight administered subcutaneously once daily. Monitoring of anticoagulant effect is not required. A single daily dose exceeding 18,000 IU should not be used.
Dosing from single-use pre-filled syringes can be determined according to the table below.

Administration twice daily
Alternatively, a dose of 100 IU/kg body weight may be administered subcutaneously twice daily. Routine monitoring of anticoagulant effect is generally not required; however, it should be considered in selected patients (see section 2: Warnings and precautions). Blood should be sampled at the time of peak plasma concentration (3 to 4 hours after subcutaneous injection). The recommended peak plasma concentrations range from 0.5 to 1.0 IU anti-Xa/mL.

Prevention of blood coagulation in extracorporeal circulation, e.g. during hemodialysis and hemofiltration in acute or chronic renal failure
Fragmin should be administered into the arterial line of the dialysis device or intravenously, selecting the most appropriate of the dosing regimens described below.

• Patients with chronic renal failure and without documented increased bleeding risk
  These patients usually require only minor dose adjustments; therefore, frequent monitoring of anti-Xa activity is generally not necessary in most patients.

• Hemodialysis and hemofiltration lasting no longer than 4 hours
  At the beginning of the procedure, a single intravenous bolus injection may be given either intravenously or into the arterial limb of the extracorporeal circuit. The recommended initial dose is 5,000 IU; alternatively, a lower initial dose may be used when clinically indicated. The initial dose of 5,000 IU for the single bolus regimen may be adjusted from session to session based on the results of the previous dialysis; the dose may be gradually increased or decreased by 500 or 1,000 IU until a satisfactory effect is achieved. Alternatively, an intravenous bolus injection of 30 to 40 IU/kg total body weight may be given, followed by a continuous intravenous infusion of 10 to 15 IU/kg body weight/hour.

• Hemodialysis and hemofiltration lasting longer than 4 hours
  A single intravenous bolus injection of 30 to 40 IU/kg body weight, followed by a continuous intravenous infusion of 10 to 15 IU/kg body weight/hour.

• Patients with acute renal failure or increased risk of bleeding
  Intravenous bolus injection of 5 to 10 IU/kg body weight, followed by continuous intravenous infusion of 4 to 5 IU/kg body weight/hour. These patients may be more unstable and may require monitoring of anti-Xa levels. Plasma anti-Xa concentration should be maintained within the range of 0.2–0.4 IU/mL.

Prophylaxis of thromboembolic complications associated with surgical procedures
Fragmin should be administered subcutaneously. Monitoring of anticoagulant effect is generally not required. If monitoring is performed, blood should be drawn at the time of peak plasma concentration (3 to 4 hours after subcutaneous injection). Recommended doses generally result in peak plasma activity ranging from 0.1 to 0.4 IU anti-Xa/mL.

General surgical procedures
Select the appropriate dosing regimen from those listed below.

• Patients at risk of thromboembolic complications
  2,500 IU subcutaneously, 2 hours before surgery, and 2,500 IU subcutaneously each morning after surgery until patient mobilization (usually treatment lasts for 5 to 7 days or longer).

• Patients with additional risk factors for thromboembolic complications (e.g. cancer)
  Administer Fragmin until patient mobilization (usually for 5 to 7 days or longer).

  1. Start treatment the day before surgery: 5,000 IU subcutaneously in the evening before surgery. After surgery, administer 5,000 IU subcutaneously each evening.
  2. Start treatment on the day of surgery: 2,500 IU subcutaneously within 2 hours before surgery and 2,500 IU subcutaneously 8 to 12 hours later, but not earlier than 4 hours after surgery. From the next day after surgery, administer 5,000 IU subcutaneously each morning.

Orthopedic surgery (e.g. hip replacement surgery)
Administer Fragmin for up to 5 weeks after surgery, selecting one of the treatment regimens below.

1. Start treatment before surgery – evening before surgery: 5,000 IU subcutaneously in the evening before surgery. After surgery, 5,000 IU subcutaneously each evening.
2. Start treatment before surgery – day of surgery: 2,500 IU subcutaneously within 2 hours before surgery and 2,500 IU subcutaneously 8 to 12 hours later, but not earlier than 4 hours after surgery. From the day after surgery, administer 5,000 IU subcutaneously daily in the morning.
3. Start treatment after surgery: 2,500 IU subcutaneously 4 to 8 hours after surgery, but not earlier than 4 hours after surgery. From the day after surgery, administer 5,000 IU subcutaneously daily.

Prophylaxis of acute deep vein thrombosis in medically immobilized patients
The recommended dose of Fragmin is 5,000 IU once daily. Treatment with dalteparin sodium should continue until the patient is no longer immobilized, for up to 14 days or longer. Monitoring of anticoagulant effect is generally not required.

Duration of treatment
Thromboprophylaxis in patients with significantly increased thromboembolic risk who are temporarily immobilized due to severe illness, such as heart failure, respiratory failure, or severe infection, should continue until full patient mobilization. The duration of treatment depends on the individual patient's condition and is usually 14 days.

Method of administration
The drop at the tip of the needle should be removed before injection, as the presence of dalteparin sodium in the injection channel may lead to a harmless superficial hematoma or, rarely, local irritation.

For detailed injection instructions, see section below How to inject Fragmin.

Unstable coronary artery disease (unstable angina and non-Q-wave myocardial infarction)
Monitoring of anticoagulant effect is generally not required, but should be considered in selected patients (see section 2: Warnings and precautions). Blood should be sampled at the time of peak plasma concentration (3 to 4 hours after subcutaneous injection). Recommended peak plasma anti-Xa activity ranges from 0.5 to 1.0 IU/mL. Concomitant administration of acetylsalicylic acid (75 to 325 mg/day) is recommended. Administer Fragmin at a dose of 120 IU/kg body weight subcutaneously every 12 hours, up to a maximum dose of 10,000 IU/12 hours. Continue treatment until clinical stabilization of the patient (usually for at least 6 days) or longer if deemed beneficial by the physician. Thereafter, prolonged treatment with a fixed dose of Fragmin is recommended until revascularization procedures (such as percutaneous interventions or coronary artery bypass grafting) are performed. The drug should not be used for longer than 45 days. The dose of Fragmin is determined based on the patient's gender and body weight:

• For women with body weight less than 80 kg and men with body weight less than 70 kg: administer 5,000 IU subcutaneously every 12 hours.
• For women with body weight at least 80 kg and men with body weight at least 70 kg: administer 7,500 IU subcutaneously every 12 hours.

Long-term treatment of symptomatic venous thromboembolic disease (proximal deep vein thrombosis and pulmonary embolism) to reduce recurrence of thromboembolic events in cancer patients
Month 1
For the first 30 days of treatment, Fragmin should be administered once daily subcutaneously (sc.) at a dose of 200 IU/kg body weight. The total daily dose should not exceed 18,000 IU.

Months 2–6
Fragmin should be administered once daily subcutaneously at a dose of approximately 150 IU/kg body weight. The dose to be administered from a single-dose pre-filled syringe is determined according to the table below.

Reduction of dose in the case of thrombocytopenia during chemotherapy
The following dosing guidelines were used in clinical trials:
In the case of chemotherapy-induced thrombocytopenia with platelet count <50,000/mm³,
administration of Fragmin should be withheld until the platelet count returns to above
50,000/mm³. If the platelet count is between 50,000 and 100,000/mm³,
the dose of Fragmin should be reduced by 17% to 33% of the initial dose (depending on the patient's body weight). Once the platelet count returns to ≥100,000/mm³,
the full dose of Fragmin should be resumed.
Table 1. Dose reduction of Fragmin in the case of thrombocytopenia in the range
50,000 – 100,000/mm³, dosing using single-dose pre-filled syringes

Renal insufficiency
In cases of severe renal insufficiency defined as creatinine concentration exceeding
3 times the upper limit of normal, the dose of Fragmin should be adjusted to maintain
anti-Xa levels at 1 IU/ml (range 0.5–1.5 IU/ml), measured 4–6 hours after
injection. If anti-Xa levels are below or above the therapeutic range,
the dose of Fragmin should be appropriately increased or decreased. Anti-Xa
levels should be re-measured after administering 3–4 injections at the adjusted dose. This dose adjustment
procedure should be repeated until anti-Xa levels reach the therapeutic range.

Use in children and adolescents
Treatment of blood clots in veins (venous thromboembolic disease (VTE))
Recommended doses depend on the child's body weight and age group and will be calculated by the physician.
The physician will inform you of the individualized dose of Fragmin according to these criteria. Do not
alter the dosing regimen or schedule without consulting your doctor.
The recommended initial doses for children and adolescents according to age are provided below:
Children aged 1 month to below 2 years: 150 IU/kg body weight twice daily.
Children aged 2 to below 8 years: 125 IU/kg body weight twice daily.
Children aged 8 to below 18 years: 100 IU/kg body weight twice daily.
The effect of Fragmin is monitored after administration of the initial dose, and the dose will then be
adjusted based on blood tests.

How to inject Fragmin
Fragmin is administered subcutaneously. This section of the leaflet explains how to administer Fragmin to yourself or your child.
Follow these instructions only after proper training by a physician. If you are uncertain about any step, contact your
physician immediately. Administer (give) the Fragmin dose at the times recommended by your doctor.
If dilution of Fragmin is required before administration to children, it should be performed by
qualified medical personnel. Follow your doctor's instructions regarding the method and timing of administration of the diluted medication.

Perform the steps described below
Step 1: Preparing the pre-filled syringe for injection of Fragmin
Remove the cap from the pre-filled syringe. An air bubble will appear in the syringe.
It should be located closest to the plunger and should not be expelled before injection.
The pre-filled syringe is ready for injection. Proceed to step 2.

The Needle-Trap needle safety system has been specifically designed to prevent needlestick injuries after proper administration of Fragmin. It consists of a plastic safety device attached to the label affixed to the syringe. It serves to avoid accidental needlesticks after proper injection of Fragmin. The Needle-Trap safety mechanism consists of a plastic flap (catch) positioned parallel along the needle, securely attached to the label on the syringe barrel.
To activate the safety system, perform the following steps: Lift the syringe, grasp the end of the plastic needle catch, and bend it away from the sheath (see Fig. 1).
Fig. 1

Remove the grey rubber needle sheath by pulling it straight off (see Fig. 2).
Fig. 2

An air bubble may be visible in the pre-filled syringe. This is normal and should be ignored.
Do not press the plunger yet, as some of the medication may be lost.
Air bubbles in single-use pre-filled syringes should not be expelled before injection, as this may result in loss of medication and consequently a reduced dose.
The pre-filled syringe is ready for injection. Proceed to step 2.

Step 2: Selecting and preparing the subcutaneous injection site
Choose one of the recommended injection sites shown below (see shaded areas in Fig. 3):
The "U"-shaped area around the navel.
The middle outer thigh.
Fig. 3

• Each time a dose is administered, inject it at a different site.
• Do not inject into areas where the skin is tender, bruised, red, or hard. Avoid areas with scars.
• If the adult or child has psoriasis, do not inject directly into any raised, thick, red, or scaly skin patches ("psoriatic skin lesions").
• Wash and dry your hands thoroughly.
• Clean the injection site with a new alcohol swab using circular motions. Allow the skin to dry completely. Do not touch the area again before injection.

Step 3: Adopting the correct position
The adult or child should be sitting or lying down for a deep subcutaneous injection. If
the patient is self-administering, sit in a comfortable seated position that allows clear visibility of the abdomen (see Fig. 4).
Fig. 4

Step 4:
Using the thumb and index finger of one hand, pinch a fold of skin. Hold the syringe in the other hand like a pencil. This will be the injection site.

Step 5:
When injecting Fragmin to an adult or to yourself, hold the pre-filled syringe over the skin fold at a 90-degree angle (i.e., vertically, as shown in the diagram, not at an angle). Insert the needle into the skin until it is fully inserted (see Fig. 5).
Fig. 5

When injecting Fragmin to a child, insert the needle into the skin with a quick, short motion at an angle between 45° and 90° (see Fig. 6).
Fig. 6

Step 6:
Press the plunger down completely at a slow, steady pace to deliver the correct dose.
Continue holding the skin fold during injection, then release it and withdraw the needle.
If bleeding occurs at the injection site, apply gentle pressure. Do not rub the injection site, as this may cause bruising.
Apply a swab to the injection site for 10 seconds. Minor bleeding may occur. Do not rub the injection site. The injection site may be covered with a dressing.

Fig. 7 Fig. 8

Step 7:
Dispose of the pre-filled syringe and needle into a sharps container. Keep the sharps container in a place inaccessible to others. When the sharps container is nearly full, dispose of it according to instructions or contact your doctor or nurse.
The dose will be adjusted according to the child's age and body weight. In younger children, a slightly higher dose of Fragmin per kg of body weight may be required than in adults. The doctor will adjust the appropriate dose for the patient. To monitor the effect of Fragmin, medical personnel may take a blood sample during treatment.
Use of Fragmin in patients with renal or hepatic impairment
Fragmin should be used with caution in patients with renal or hepatic impairment (see section 2: Warnings and precautions).
Administration of a higher than recommended dose of Fragmin
Depending on the symptoms present, the doctor will administer appropriate treatment. The anticoagulant effect of Fragmin can be neutralized by administration of protamine. However, protamine inhibits primary haemostasis; therefore, it should only be used in cases of real danger.
A dose of 1 mg protamine partially neutralizes the effect of 100 IU (anti-Xa) of Fragmin (although the prolonged clotting time is completely neutralized, 25%-50% of the anti-Xa activity of dalteparin sodium remains).

4. Possible adverse reactions

Common (may occur in up to 1 in 10 people)

• Mild, reversible thrombocytopenia (type I)
• Bleeding (haemorrhage)
• Transient increase in aminotransferase activity (liver enzymes, AspAT, AlAT)
• Subcutaneous haematoma at the injection site
• Pain at the injection site

Uncommon (may occur in up to 1 in 100 people)

• Hypersensitivity

Rare (may occur in up to 1 in 1,000 people)

• Skin necrosis
