1. What is Clexane Forte and what is it used for
Clexane Forte contains the active substance enoxaparin sodium. It belongs to a group of medicines called low molecular weight heparins or LMWH.
How Clexane Forte works
Clexane Forte works in two ways.
- 1) It prevents the growth of existing blood clots. This helps the body to dissolve existing blood clots, making them no longer harmful.
- 2) It prevents the formation of new blood clots in the patient's blood.
What Clexane Forte is used for
Clexane Forte can be used for:
- Treating blood clots that are already present in the patient's blood.
- Preventing the formation of blood clots in the patient's blood in the following cases: before and after surgery, during short-term illness when the patient will be unable to move for some time, in patients who have developed blood clots in the circulating blood due to cancer, to further prevent the formation of new blood clots
- Preventing the formation of blood clots in unstable angina (when insufficient blood is supplied to the heart muscle) or after a heart attack
- Preventing the formation of clots in dialysis tubes (used in people with severe kidney function disorders).
2. Important information before using Clexane Forte
Do not use Clexane Forte if:
- the patient is allergic to:
o enoxaparin sodium or any of the other ingredients of this medicine (listed in section 6) o heparin or other low molecular weight heparins, such as nadroparin, tinzaparin, or dalteparin. Symptoms of an allergic reaction may include: rash, difficulty breathing or swallowing, swelling of the face, lips, tongue, mouth, throat, or eyes.
- the patient has had a reaction to heparin that caused a significant decrease in the number of blood cells responsible for blood clotting (platelets) in the last 100 days.
- there are antibodies against enoxaparin in the patient's blood.
- the patient has severe bleeding or a medical condition associated with an increased risk of bleeding, such as: o stomach ulcers, recent brain or eye surgery, or recent hemorrhagic stroke.
- the patient is using Clexane Forte to treat blood clots and spinal puncture or surgery is planned within 24 hours: o lumbar puncture o surgical procedure under spinal or epidural anesthesia. Clexane Forte should not be used in these patients. If in doubt, consult your doctor or pharmacist before starting Clexane Forte.
Warnings and precautions
Clexane Forte should not be exchanged with other low molecular weight heparins such as nadroparin, tinzaparin, or dalteparin. This is because they are not exactly the same, differ in activity, and have different instructions for use. Before starting Clexane Forte, discuss with your doctor or pharmacist if:
- the patient has ever had a reaction to heparin that caused a significant decrease in the number of blood cells responsible for blood clotting (platelets)
- the patient has a heart valve replacement
- the patient has endocarditis (infection of the membrane lining the heart)
- the patient has stomach ulcers
- the patient has recently had a brain stroke
- the patient has high blood pressure
- the patient has diabetes or has problems with blood vessels in the eyes caused by diabetes (so-called diabetic retinopathy)
- the patient has recently had eye or brain surgery
- the patient is elderly (over 65 years), especially if they are over 75 years old
- the patient has kidney disease
- the patient has liver disease
- the patient is underweight or overweight
- the patient has an increased level of potassium in the blood (which can be checked with a blood test)
- the patient is currently taking medications that may cause bleeding (see section 2 "Clexane Forte and other medicines")
- the patient has spinal problems or has had spinal surgery. If any of the above situations apply to the patient or if the patient has doubts, consult a doctor or pharmacist before starting Clexane Forte.
In the case of patients taking doses greater than 210 mg/day, this medicine contains more than 24 mg of sodium (the main component of table salt) per dose. This corresponds to 1.2% of the maximum recommended daily intake of sodium in the diet for adults.
Examinations and monitoring
Before starting this medicine and periodically during its use, the patient may undergo a blood test to check the number of platelets responsible for blood clotting and potassium levels in the blood.
Use in children and adolescents
The safety and efficacy of Clexane Forte have not been evaluated in children and adolescents.
Clexane Forte and other medicines
Tell your doctor or pharmacist about all medicines you are currently taking, have recently taken, or plan to take.
- warfarin - a medicine used to thin the blood
- aspirin (also known as acetylsalicylic acid or ASA), clopidogrel, or other medicines used to prevent blood clots (see section 3 "Change of anticoagulant medicine")

- The doctor will decide how long the patient should receive Clexane Forte.
STEMI in patients 75 years of age or older:
- The usual dose is 75 IU (0.75 mg) per kilogram of body weight every 12 hours.
- The maximum dose of Clexane Forte in the first two doses is 7500 IU (75 mg).
- The doctor will decide how long the patient should receive Clexane Forte.
Patient undergoing percutaneous coronary intervention (PCI):
- Depending on when the last dose of Clexane Forte was administered, the doctor may decide to administer an additional dose of Clexane Forte before the PCI procedure. The medicine will be administered intravenously.
- 4) Prevention of blood clot formation in dialysis tubes
- The usual dose is 100 IU (1 mg) per kilogram of body weight.
- Clexane Forte is injected into the tube returning blood from the body (into the so-called arterial line) at the beginning of the dialysis session. This dose usually lasts for a 4-hour dialysis session. However, if necessary, the doctor may administer an additional dose of 50 IU to 100 IU (0.5 to 1 mg) per kilogram of body weight.
Self-administration of Clexane Forte. If the patient is able to self-administer Clexane Forte, the doctor or nurse will demonstrate how to do it. Do not attempt to self-administer if you have not been trained. If you have any doubts, consult your doctor or nurse immediately. Administering the injection correctly under the skin (so-called subcutaneous injection) can reduce pain and bruising at the injection site.
Before self-administering Clexane Forte
- Prepare all necessary items: syringe, alcohol swab, soap and water, and a container for medical waste.
- Check the expiration date on the packaging. Do not use the medicine after the expiration date.
- Check if the syringe is damaged and if the liquid is clear. If not, use another syringe.
- Make sure what dose is to be administered.
- Examine the abdomen to check if the last injection has caused redness, skin color change, swelling, discharge, or if it is still painful. If so, consult your doctor or nurse.
Instructions for self-administering Clexane Forte: (Instructions for pre-filled syringes without a safety system)
Preparing the injection site
- 1) Choose an injection site in the right or left side of the abdomen. The injection site should be at least 5 cm away from the navel towards the sides.
- Do not inject within 5 cm of the navel or around existing scars or bruises.
- Change the injection site between the left and right side of the abdomen, depending on the location of the previous injection.

- 2) Wash your hands. Clean the injection site with an alcohol swab or soap and water.
- 3) Sit or lie down in a comfortable position, so you are relaxed. Make sure the injection site is in your line of sight. A chair, couch, or bed with pillows for support will be suitable.
Dose selection
- 1) Carefully remove the needle cap from the syringe. Discard the cap.
- Do not press the plunger before administering the injection to remove air bubbles. This may reduce the administered dose.
- After removing the cap, do not touch the needle. This will ensure the sterility of the needle.

- 2) If the amount of medicine in the syringe is consistent with the prescribed dose, there is no need to adjust the dose. You can now administer the injection.
- 3) If the dose depends on body weight, it may be necessary to adjust the dose in the syringe according to the prescribed dose. In this case, remove excess medicine by holding the syringe upside down (to maintain air bubbles in the syringe) and discard excess medicine into a container.
- 4) A drop may appear at the end of the needle. If so, remove the drop before administering the injection by tapping the syringe with the needle facing down. You can now administer the injection.
Injection
- 1) Hold the syringe in the hand you write with (like a pencil). With your other hand, gently grasp the cleaned abdominal skin with your index finger and thumb, creating a skin fold between your fingers.
- Make sure to maintain the skin fold during the injection.
- 2) Hold the syringe with the needle facing down (perpendicularly at a 90° angle). Insert the entire length of the needle into the skin fold.

- 3) Press the plunger with your thumb. This will introduce the medicine into the abdominal fat tissue. Administer the entire amount of medicine from the syringe.
- 4) Remove the needle from the injection site, pulling it out straight. Keep the needle away from yourself and others. Now you can release the skin fold.

After administering the injection
- 1) To avoid bruising, do not rub the injection site after administering the injection.
- 2) Dispose of the used syringe in a container for medical waste. Close the container and store it in a place that is out of sight and reach of children. If the container is full, dispose of it according to the doctor's or pharmacist's instructions. Dispose of any unused medicine or waste in accordance with local regulations.

Stopping Clexane Forte treatment
It is important to continue administering Clexane Forte injections until the doctor recommends stopping them. If treatment is stopped, a blood clot may form, which can be very dangerous. If you have any further doubts about using this medicine, consult your doctor, pharmacist, or nurse.
4. Possible side effects
Like all medicines, Clexane Forte can cause side effects, although not everybody gets them.
Severe side effects
Stop using Clexane Forte and consult your doctor or nurse immediately if you experience symptoms of a severe allergic reaction (such as rash, difficulty breathing or swallowing, swelling of the face, lips, tongue, mouth, throat, or eyes).
If you experience any of the following symptoms, stop using enoxaparin and seek medical attention immediately:
- A red, scaly, widespread rash with thickening of the skin and blisters, accompanied by fever. These symptoms usually appear at the beginning of treatment (acute generalized exanthematous pustulosis).
Like other similar medicines used to reduce blood clotting, Clexane Forte can cause bleeding. This can be life-threatening. In some cases, bleeding may not be immediately visible.
Consult your doctor immediately if:
- the patient experiences any bleeding that does not stop on its own
- the patient has signs of excessive bleeding, such as weakness, fatigue, paleness, dizziness with headaches, or swelling of unknown origin. The doctor may decide to monitor the patient more closely or change the medicine.
Consult your doctor immediately:
- if the patient experiences any signs of a blood clot blocking a blood vessel, such as: o severe, crampy pain, redness, increased warmth, or swelling in one leg - these are symptoms of deep vein thrombosis o shortness of breath, chest pain, fainting, or coughing up blood - these are symptoms of pulmonary embolism
- if the patient experiences a painful rash or dark red spots under the skin that do not disappear when pressed. The doctor may order blood tests to check the platelet count.
Other side effects:
Very common(may affect more than 1 in 10 people):
- bleeding
- increased liver enzyme activity.
Common(may affect up to 1 in 10 people):
- increased tendency to bruise. This may be due to a decrease in platelet count

- skin rash (hives)
- itching, red skin
- bruising or pain at the injection site
- decreased red blood cell count
- increased platelet count
- headaches.
Uncommon(may affect up to 1 in 100 people):

- feeling of tenderness and swelling in the stomach - may be a sign of bleeding into the stomach
- large, red, irregularly shaped skin lesions with blisters or without blisters
- skin irritation (local irritation)
- the patient may notice yellowing of the skin or eyes and darker urine. This may indicate liver disease.
Rare(may affect up to 1 in 1000 people):
- severe allergic reaction - symptoms may include: rash, difficulty swallowing or breathing, swelling of the lips, face, throat, or tongue
- increased potassium levels in the blood - this is more likely in people with kidney disease or diabetes. The doctor may check this with a blood test
- increased eosinophil count in the blood - the doctor may check this with a blood test
- hair loss
