6. Contents of the container and additional information

Fragmin belongs to a group of medications called low molecular weight heparins.

Fragmin 10,000 UI/ml is used in adults aged 18 years or older for:

• Treatment of deep vein thrombosis with or without pulmonary embolism (to treat existing blood clots in deep veins - a type of blood vessels).
• Prevention of extracorporeal coagulation during hemodialysis and hemofiltration in patients with chronic renal insufficiency (to prevent clot formation in the dialyzer during dialysis or blood filtration performed in patients with a decreased kidney function).
• Treatment of unstable angina and myocardial infarction without Q wave (a type of heart attack).
• Prophylaxis of thromboembolic disease in patients with cancer.

Do not use Fragmin if:

• You are allergic (hypersensitive) to dalteparin sodium, any of the other components of this medication (including in section 6), any type of heparin (blood clotting medications) other than dalteparin sodium or products derived from pork
• You have an acute peptic ulcer, cerebral hemorrhage, or other significant bleeding
• You have severe coagulation disorders
• You have an acute or subacute bacterial endocarditis (inflammation of one of the heart membranes due to an infection)
• You have undergone surgery in the central nervous system, eyes, or ears, or if you have trauma to these organs or systems
• You have a decrease in the number of platelets (cells present in the blood that intervene in blood clotting) and when a platelet aggregation test is performed in the presence of dalteparin sodium, the result is positive.

If you are being treated with Fragmin, you will not be able to receive epidural or spinal anesthesia.

Warnings and precautions:

Consult your doctor, pharmacist, or nurse before starting to use Fragmin if:

• You are to receive intramuscular injections of other medications due to the risk of hematomas.
• You have a decrease in the number of platelets or defects in them. Your doctor may request specific tests to determine the cause of this problem.
• You have severe renal insufficiency (decrease in kidney function) or severe liver insufficiency (decrease in liver function).
• You have uncontrolled high blood pressure.
• You have retinal disorders (a part of the eye) due to diabetes or uncontrolled high blood pressure.
• You have recently undergone surgery or have a high risk of bleeding.
• You have had an acute myocardial infarction and are being treated with this medication.
• You are at risk of developing hyperkalemia (elevated potassium levels in the blood) due to a disease or taking certain medications. Your doctor may perform tests to measure potassium levels.
• You are undergoing epidural or spinal anesthesia, or lumbar puncture, and are being administered heparin for prevention, very rarely hematomas may appear in these areas. If you experience back pain, numbness, weakness in the lower extremities, or any disorder in the functioning of the intestines or bladder, immediately inform your doctor.
• You have a heart valve prosthesis, the preventive doses of Fragmin may not be sufficient to prevent valve thrombosis.
• You are receiving prolonged treatment for unstable coronary disease, such as before revascularization, your doctor may reduce your Fragmin dose.

Considering your condition and/or age, your doctor may perform tests to control anticoagulant activity and prevent the risk of bleeding or recurrence of thrombosis.

Fragmin should not be exchanged with other unfractionated heparins, low molecular weight heparins, or synthetic polysaccharides, as its effect may not be the same.

Children and adolescents:

Fragmin is not used in newborns under 1 month of age.

Use of Fragmin with other medications:

Inform your doctor, pharmacist, or nurse if you are using, or have recently used, other medications, including those purchased without a prescription.

It is especially important to inform your doctor if you are taking any of the following medications:

• Those that affect the blood and blood clotting, such as aspirin, vitamin K antagonists (which prevent the action of vitamin K, whose function is to facilitate blood clotting, such as Sintrom -acenocoumarol-), and dextran. However, if you suffer from unstable angina or myocardial infarction without Q wave (a type of myocardial infarction), you should receive low-dose oral aspirin, unless contraindicated.
• A type of medications called nonsteroidal anti-inflammatory drugs (NSAIDs) and aspirin, for the treatment of inflammation and pain, especially in patients with renal insufficiency (decrease in kidney function).

• Bleeding at any point, which has sometimes been fatal
• Temporary increase in liver enzymes

Adverse effects of unknown frequency (cannot be estimated from available data):

• Decrease in the number of blood platelets mediated by immune mechanisms induced by heparin (type 2)
• Severe allergic reactions

• Rash
• Accumulation of blood in the interior of the skull or spinal column (epidural or spinal hematoma)
