Warnings and precautions

Consult your doctor before starting to use Traleusin if you have or have had any of the following conditions:

• if aprevious treatmentwith heparins (a group of antithrombotic medications administered frequently) caused a significant decrease in platelet count, known as heparin-induced thrombocytopenia, and a blood test determined that it cannot be ruled out that a similar effect may occur if Traleusin is administered;
• kidney problems;
• liver problems;
• an ulcer in the digestive tract or another condition that may increase the risk of bleeding;
• low body weight (less than 55kg) or obesity (more than 90kg);
• if you are currently taking medications that may affect bleeding (see section2 “Other medications and Traleusin”);

• hypersensitivity tosodium sulfite, as this may cause severe allergic reactions in asthmatic patients;
• if Traleusin is to be used during acoronary artery bypassoperation;
• if you are to receivespinal or epidural anesthesia or lumbar puncture: a period of delay should be respected between the administration of Traleusin and this procedure.

It is recommended that the healthcare professional record the name and batch number of the medication being used.

Driving and operating machinery

The effect of Traleusin on the ability to drive or operate machinery is unknown.

Traleusin contains sodium sulfite

Rarely, it may cause severe hypersensitivity reactions and bronchospasm.

Traleusin contains sodium

This medication contains less than 1mmol of sodium (23mg) per 0.6ml; it is essentially “sodium-free”.

The administration will be handled by a healthcare professional with the necessary training and experience. They will determine the correct dose for you and the timing and method of injection administration.

A doctor or nurse will administer Traleusin. This medication is administered by injection under the skin or as an injection or infusion into a vein. This medication should not be injected into a muscle.

The recommended dose is:

Your doctor will calculate the dose of Traleusin you need based on:

• the underlying disease you have;
• the risk of blood clots;
• the risk of bleeding;
• your overall health and physical characteristics (e.g., weight);
• whether you are hypersensitive to heparins.

Prevention of blood clots when heparin cannot be administered

The dose for the prevention of blood clots depends on the patient's body weight. Treatment is continued for a maximum of 14days. In some cases, this medication may be administered for a longer period of time.

Patients with a significant acute decrease in platelet count during heparin administration (thrombocytopenia, see section1) usually require higher doses.

Treatment of blood clots in patients withheparin-induced thrombocytopenia

In patients with heparin-induced thrombocytopenia, the initial dose injected depends on the patient's body weight. After the initial dose, the dose is gradually reduced.

Vascular surgery or invasive vascular procedures

For vascular surgeries that do not require abypass machine,the initial dosedepends on the patient's body weight.The treatment continues for 5-7days and is administered no less than 6 hours after the operation.

Cardiopulmonary procedure

Traleusin will be injected during the operation after the chest is opened (thoracotomy) and will continue to be administered as long as necessary.

Due to the risk of bleeding, Traleusin should only be administered for surgical procedures in patients who do not respond satisfactorily to other medications for blood clot prevention and whose operation cannot be postponed.

Monitoring

Depending on your situation (e.g., if you have kidney problems or are overweight), your doctor may perform additional blood tests during treatment to adjust the dose.

Switching to oral anticoagulants

Your doctor may decide to switch you to a treatment with oral anticoagulants.

Switching from Traleusin to anticoagulants called vitamin K antagonists (AVK)

Your doctor will perform a blood test called INR and will indicate when to properly discontinue Traleusin.

Use in children and adolescents

Traleusin can be administered to children. Your doctor will take into account the age and weight to determine the dose and may perform blood tests during treatment to adjust the dose. There is no experience with the administration of danaparoid sodium in children 2 to 7years old.

If you take more Traleusin than you should

Since your doctor or nurse will closely monitor your condition, it is unlikely that you will be given too much Traleusin and, when necessary, they will adjust the doses.

If an excessive dose is administered, you may experience unusual bleeding. This may be observed as:

• nosebleeds, bleeding gums;
• black stools (may indicate bleeding from the stomach or intestines);
• blood in the urine;
• abnormally heavy menstrual bleeding.

Inform your doctor or nurse if you experience any of these symptoms or other symptoms of unusual bleeding.

If you forget to take Traleusin

Since your doctor or nurse will closely monitor your condition, it is unlikely that you will receive a low dose of this medication. If necessary, they will adjust the dose.

Your doctor will decide when to discontinue treatment with this medication.

If you have any other questions about the use of this medication, ask your doctor.

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

When heparin (an anticoagulant) is administered with a spinal injection, bruising may appear on the spine. This occurs in very rare instances (see section2).

However, if you experience any of the following symptoms:

• back pain;
• tingling, numbness, or weakness in the legs;
• problems with the intestines or bladder;

inform your doctor or nurse immediately, as you may need treatment.

Traleusin may increase the risk of bleeding. Bleeding may occur after the operation and bleeding or blood loss near the site of the operation.

Frequent (may affect up to 1 in 10patients):

• Significant decrease in platelet count (thrombocytopenia) in patients hypersensitive to heparin
• skin rash
• Increased bleeding after the operation

Infrequent (may affect up to 1 in 100people):

• bruising, pain, or bleeding near the injection site
• allergic reactions (hypersensitivity)
• itching (pruritus)

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

• Increased bleeding or swelling with blood at the operation site (hematoma)
• Decrease in platelet count due to an autoimmune disorder (autoimmune thrombocytopenia)
