6. Contents of the container and additional information

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

Fragmin 18,000 UI/0.72 ml is used in adults aged 18 years and above for:

-Treatment of deep vein thrombosis with or without pulmonary embolism (to treat existing blood clots in deep veins - a type of blood vessels).

-Prophylaxis of thromboembolic disease in patients with cancer.

No use Fragmin si:

• Is allergic (hypersensitive) to dalteparin sodium, to any of the other components of this medication (including in section 6), to any type of heparin (blood clotting medications) other than dalteparin sodium or to products derived from pork
• Has acute peptic ulcer disease, cerebral hemorrhage, or other significant bleeding
• Has severe coagulation disorders
• Has acute or subacute bacterial endocarditis (inflammation of one of the heart membranes due to an infection)
• Has undergone surgery in the central nervous system, eyes, or ears, or presents trauma to these organs or systems
• Has 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.

• Has a decrease in the number of platelets or defects in the same. Your doctor may request specific tests to determine the cause of this problem.

-Has severe renal insufficiency (decrease in kidney function) or severe liver insufficiency (decrease in liver function).

-Has uncontrolled high blood pressure.

-Has retinal disorders (part of the eye) due to diabetes or high blood pressure.

-Has recently undergone surgery or has a high risk of bleeding.

-Has had an acute myocardial infarction and is being treated with this medication.

-Has a risk of elevated potassium levels in the blood due to a disease or by taking certain medications. Your doctor may perform tests to measure potassium levels.

• Is undergoing epidural (one of the membranes surrounding the brain and spinal cord) or spinal (spinal cord) anesthesia or lumbar puncture, and heparin is administered for prevention; very rarely, hematomas may appear in these areas. If you experience back pain, numbness, weakness in the lower extremities, or any bowel or bladder dysfunction, inform your doctor immediately.
• Has a heart valve prosthesis, the preventive doses of Fragmin may not be sufficient to prevent valve thrombosis.
• Is receiving prolonged treatment for unstable coronary disease, such as before revascularization, your doctor may reduce your Fragmin dose.
• Is allergic or suspects a possible allergy to latex (natural rubber) or if the cap of the pre-filled Fragmin syringe is to be handled by someone with a known or suspected latex allergy. The cap of the pre-filled Fragmin syringe is made of latex (natural rubber) and may cause severe allergic reactions in people with latex allergy.

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.

Do not interchange Fragmin with other non-fractionated 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, even those purchased without a prescription.

Certain medications may interact with Fragmin 18,000 UI/0.72 ml; in these cases, it may be advisable to change the dose or discontinue treatment with one of the medications.

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

Pregnancy and lactation

Fragmin is administered subcutaneously (injection under the skin).

If you are to be administered Fragmin 18,000 UI/0.72 ml to treat existing blood clots in deep veins, treatment will begin as soon as possible, and will continue for at least 5 days or until the levels of the prothrombin complex (factors involved in blood coagulation) return to their normal level. You may be administered one or two doses daily.

If you are administered a daily dose, it will be 200 UI per kilogram of body weight and per day, and will be applied via injection under the skin. The daily dose will not exceed 18,000 UI.

If you are administered two daily doses, they will be 100 UI per kilogram of body weight and per day.

If necessary, your doctor will perform analytical controls.

Fragmin 18,000 UI/0.72 ml injections will normally be administered by a healthcare professional, and will be applied under the skin, in the anterior or posterior abdominal area, and alternately on the right and left sides.

Use in children and adolescents

Treatment of blood clots in veins (symptomatic deep vein thrombosis [DVT])

The recommended doses depend on the child's body weight and age group. The doctor will make the calculation. The doctor will advise you on the individualized dose of Fragmin according to these criteria. Do not change the dose or treatment schedule without consulting your doctor first.

This medication is not suitable for use in the pediatric population becausethe pre-filled syringes do not allow for dose adjustmentbased on the child's body weight. It is recommended to use the 2,500 UI/ml injectable solution in 4 mL vials.

The effect of Fragmin will be controlled after the initial dose and subsequent dose adjustment through a blood test.

How to inject Fragmin

Fragmin is administered via subcutaneous injection. This section of the leaflet explains how to administer Fragmin. You should follow these instructions

only after having been trained by your doctor. If you are unsure of what to do, speak with your doctor immediately. You should inject (or administer) the Fragmin dose at the recommended times by your doctor.

If it is necessary to dilute Fragmin before administering it, it should be done by a healthcare professional. You should follow your doctor's instructions on how and when to inject the diluted medication provided.

Please follow the steps explained below

Step1: The way to prepare the syringe for injection will depend on the specific presentation of Fragmin to be used.

The Needle-Trap safety system is especially designed to help prevent accidents with needles after the correct use of Fragmin. It consists of a plastic safety device attached to the syringe label. It is used to prevent accidental needle pricks after the correct injection of Fragmin. The needle protection device (Needle-Trap) consists of a plastic latch (pinch) aligned in parallel with the needle, firmly attached to the syringe cylinder label.

The following actions are required to activate the safety system: Lift the syringe, hold the plastic needle blocker, and fold it away from the protector (see Figure1).

Figure1

Remove the gray rubber cap by pulling it outwards (see Figure2).

Figure2

You will notice a bubble of air in the syringe. This is expected and can be ignored. It is essential not to push the plunger yet, as some of the medication may be lost. The air bubble in disposable syringes should not be expelled before injection, as this may cause medication loss and, therefore, a reduction in dose.

You are now ready to administer the injection. Continue with Step2.

Step2: Choosing and preparing the subcutaneous injection site

Choose one of the recommended injection sites below (see the shaded areas in Figure3):

• A "U" shaped area around the navel.
• Central area of the thighs.

Figure3

•Use a different injection site each time a dose is administered.

•Do not administer the injection in areas where the skin is painful, bruised, red, or hard. Avoid areas with scars.

•If you or the child have psoriasis, do not administer the injection directly on any raised, thick, red, or scaly skin patches ("psoriasis skin lesions").

•Wash and dry your hands.

•Clean the injection site with a new alcohol-soaked swab, moving in circular motions. Allow the skin to dry completely. Do not touch this area again before administering the injection.

Step3: Adopting the correct posture

You or the child should be seated or lying down for the subcutaneous injection. If you are self-administering the medication, sit in a comfortable position where you can see your abdomen (see Figure4).

Figure4

Step4:

With your thumb and index finger, lift a fold of skin with one hand. With the other hand, hold the syringe as if it were a pencil. This will be the injection site.

Step5:

If you are injecting Fragmin into an adult or yourself,hold the syringe over the skin fold, keeping it at a right angle (i.e., vertical, as in the diagram, and not at an angle). Insert the needle into the skin until it is fully inside (see Figure5).

Figure5

If you are injecting Fragmin into a child,insert the needle into the skin until it reaches the bottom with a small, quick movement, at an angle of between 45° and 90° (see Figure6).

Figure6

Step 6:

Push the plunger all the way down at a slow and constant speed to administer the correct dose. Continue pinching the skin fold while administering the injection and then release the skin fold and remove the needle.

If there is any bleeding at the injection site, apply gentle pressure. Do not rub the injection site, as this may cause hematomas.

Press the injection site with a cotton ball for 10seconds. Some bleeding may occur. Do not rub the injection site. You can place a bandage over the injection site.

Step7: If your syringe has a Needle-Trap device, activate it

Place the plastic needle blocker against a hard, stable surface and, with one hand, turn the syringe cylinder upwards against the needle, forcing the needle into the blocker until it fits(see Figure7).

Continue folding the needle until the syringe exceeds a 45degree angle with the flat surface to permanently inactivate it(see Figure8).

(see Figure7)(see Figure8)

Step8:

Dispose of the syringe and needle in a sharp object container. Keep the sharp object container out of reach of others. When the sharp object container is almost full, dispose of it according to the instructions or speak with your doctor or nurse.

If you use more Fragmin than you should

If you have used more Fragmin than you should, consult your doctor or pharmacist immediately, go to the nearest hospital, or contact the Toxicology Information Service, Tel. 91 562 04 20.

If you forget to use Fragmin

Consult your doctor or pharmacist immediately.

Do not administer a double dose to compensate for the missed doses.

Like all medications, Fragmin may produce adverse effects, although not all people will experience them.

Adverse effects observed frequently (may affect up to one in 10 patients):

• Pain and appearance of petechiae at the injection site
• Reversible decrease in blood platelet count not mediated by immune mechanisms (type 1)
• Bleeding at any site, which has sometimes been fatal
• Temporary increase in liver enzymes

Rare adverse effects (may affect up to one in 1,000 patients):

• Hair loss, skin cell death

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

• Decrease in blood platelet count mediated by immune mechanisms induced by heparin (type 2)
• Severe allergic reactions
• Localized bleeding in the interior of the skull, abdomen, or other areas, sometimes fatal
• Rash
• Accumulation of blood in the interior of the skull or spinal column (epidural or spinal hematoma)
• Elevation of potassium levels in the blood
• Osteoporosis (bone porosity).

It is expected that adverse effects in children will be the same as those in adults. However, there is limited information on possible adverse effects with prolonged use in children.
