1. What is Kardatuxan and what is it used for

Kardatuxan contains the active substance rivaroxaban and is used in adults to

• prevent the formation of blood clots in the veins after hip or knee replacement surgery. The doctor has prescribed this medicine because the risk of blood clot formation is increased after surgery.
• treat blood clots in the veins of the legs (deep vein thrombosis) and in the blood vessels of the lungs (pulmonary embolism) and prevent the recurrence of blood clots in the blood vessels of the legs and/or lungs.

Kardatuxan belongs to a group of medicines called anticoagulants. Its action is based on blocking the blood clotting factor (factor Xa) and thus reducing the tendency to form blood clots.

2. Important information before taking Kardatuxan

When not to take Kardatuxan

• if the patient is allergic to rivaroxaban or any of the other ingredients of this medicine (listed in section 6),
• if the patient has excessive bleeding,
• if the patient has a disease or condition that leads to an increased risk of serious bleeding (e.g., stomach ulcer, injury or bleeding into the brain, recent brain or eye surgery),
• if the patient is taking other medicines that prevent blood clotting (e.g., warfarin, dabigatran, apixaban, or heparin), except when switching anticoagulant therapy or when heparin is used to maintain catheter patency in a vein or artery,
• if the patient has liver disease that leads to an increased risk of bleeding,
• if the patient is pregnant or breastfeeding. Do not take Kardatuxan, and also inform your doctorif you suspect that these circumstances have occurred.

Warnings and precautions

Before starting to take Kardatuxan, consult your doctor or pharmacist.

When to be particularly careful when taking Kardatuxan

• if the patient has an increased risk of bleeding, such as:
• moderate or severe kidney disease, as kidney function may affect the amount of medicine that works in the patient's body,
• if the patient is taking other medicines that prevent blood clotting (e.g., warfarin, dabigatran, apixaban, or heparin), except when switching anticoagulant therapy or when heparin is used to maintain catheter patency in a vein or artery (see "Kardatuxan and other medicines"),
• bleeding disorders,
• very high blood pressure that does not decrease despite taking medicines,
• stomach or intestinal diseases that may cause bleeding, e.g., inflammation of the intestines and stomach or inflammation of the esophagus (throat and esophagus) e.g., due to reflux disease of the esophagus (stomach acid flowing back into the esophagus) or tumors located in the stomach or intestines, or the genital or urinary system,
• vascular disease of the back of the eye (retinopathy),
• lung disease in which the airways are dilated and filled with pus (bronchiectasis) or previous bleeding from the lungs,
• in patients with artificial heart valves,
• if the patient has a disorder called antiphospholipid syndrome (an immune system disorder that increases the risk of blood clot formation), the patient should inform their doctor, who will decide whether to change the treatment,
• if the patient has abnormal blood pressure or is scheduled for surgery or other treatment to remove a blood clot from the lungs.

If the patient suspects that they have any of the above conditions, they should inform

their doctorbefore taking Kardatuxan. The doctor will decide whether to use this medicine and whether the patient should be monitored particularly closely.

3. How to take Kardatuxan

Always take this medicine exactly as your doctor has told you. If you are unsure, consult your doctor or pharmacist.

How many tablets to take

• To prevent blood clots in the veins after hip or knee replacement surgery, the recommended dose is one 10 mg Kardatuxan tablet taken once a day.
• In the treatment of blood clots in the veins of the legs, blood clots in the blood vessels of the lungs, and to prevent the recurrence of blood clots, after at least 6 months of treatment for blood clots, the recommended dose is one 10 mg tablet once a day or one 20 mg tablet once a day. Your doctor has prescribed Kardatuxan 10 mg once a day for you.

Swallow the tablet whole, preferably with water.
Kardatuxan can be taken with or without food.
If you have difficulty swallowing the whole tablet, you should talk to your doctor about other ways to take Kardatuxan. The tablet can be crushed and mixed with water or soft food, such as apple sauce, immediately before taking it.
If necessary, your doctor may administer the crushed Kardatuxan tablet through a gastric tube.

When to take Kardatuxan

Take one tablet every day until your doctor decides to stop the treatment.
It is best to take the tablet at the same time every day, as it is easier to remember.
Your doctor will decide how long to continue the treatment.
To prevent blood clots in the veins of the legs after hip or knee replacement surgery:
The first tablet should be taken 6 to 10 hours after surgery.
In patients after major hip surgery, treatment usually lasts 5 weeks.
In patients after major knee surgery, treatment usually lasts 2 weeks.

Taking more Kardatuxan than prescribed

If you have taken more Kardatuxan than prescribed, you should immediately contact your doctor. Taking too much Kardatuxan increases the risk of bleeding.

Missing a dose of Kardatuxan

If you have forgotten to take a dose, you should take the tablet as soon as you remember. Take the next tablet the next day, and then take the tablets as usual, once a day.
Do not take a double dose to make up for the missed tablet.

Stopping Kardatuxan treatment

You should not stop taking Kardatuxan without first talking to your doctor, as Kardatuxan prevents the occurrence of a serious disease.
If you have any further doubts about taking this medicine, you should consult your doctor or pharmacist.

4. Possible side effects

Like all medicines, Kardatuxan can cause side effects, although not everybody gets them.
