1. What is Privenax and what is it used for
This medicine contains the active substance dabigatran etexilate and belongs to a group of medicines called anticoagulants. It works by blocking a substance in the body involved in the formation of blood clots.
Dabigatran is used in adults to:
- prevent the formation of blood clots in the veins after knee or hip replacement surgery.
- prevent the formation of blood clots in the brain (stroke) and in other blood vessels of the body if you have a type of irregular heartbeat called non-valvular atrial fibrillation and have at least one additional risk factor.
- treat blood clots in the veins of your legs and lungs and to prevent them from happening again in the veins of your legs and lungs.
Dabigatran is used in children to:
- treat and prevent blood clots.
2. What you need to know before you take Privenax
Do not take Privenax
- if you are allergic to dabigatran etexilate or any of the other ingredients of this medicine (listed in section 6).
- if your kidney function is severely reduced.
- if you are currently bleeding.
- if you have any disease in an organ of the body that increases the risk of severe bleeding (e.g. stomach ulcer, injury or bleeding in the brain, recent brain or eye surgery).
- if you are prone to bleeding. This tendency may be congenital, of unknown cause or caused by other medicines.
- if you are taking medicines to prevent blood clotting (e.g. warfarin, rivaroxaban, apixaban or heparin), except when switching from one anticoagulant treatment to another, while having a venous or arterial catheter and being administered heparin through this catheter to keep it open or while your normal heartbeat is being restored through a procedure called catheter ablation for atrial fibrillation.
- if your liver function is severely reduced or you have a life-threatening liver disease.
- if you are taking oral ketoconazole or itraconazole, medicines used to treat fungal infections.
- if you are taking oral cyclosporin, a medicine used to prevent organ rejection after a transplant.
- if you are taking dronedarone, a medicine used to treat irregular heartbeat.
- if you are taking a combination product of glecaprevir and pibrentasvir, an antiviral medicine used to treat hepatitis C.
- if you have been implanted with an artificial heart valve that requires permanent anticoagulant treatment.
Warnings and precautions
Talk to your doctor before starting to take dabigatran. During treatment with this medicine, you may also need to talk to your doctor if you experience any symptoms or if you need to have surgery.
Tell your doctorif you have or have had any disorder or disease, especially any of the following:
- If you have an increased risk of bleeding, for example:
- if you have recently had bleeding.
- if you have had a tissue removal (biopsy) in the last month.
- if you have had a severe injury (e.g. a bone fracture, a head injury or any injury that required surgical treatment).
- if you have inflammation of the esophagus or stomach.
- if you have problems with gastric juice reflux in the esophagus.
- if you are taking medicines that may increase the risk of bleeding. See "Other medicines and dabigatran" below.
- if you are using anti-inflammatory medicines such as diclofenac, ibuprofen or piroxicam.

- If you have a liver disease associated with changes in blood tests. The use of dabigatran is not recommended in this case.
Be careful with dabigatran
- If you need to have surgery:
In this case, dabigatran should be temporarily stopped due to a higher risk of bleeding during and after surgery. It is very important that you take this medicine before and after surgery exactly at the times indicated by your doctor.
- If surgery requires the placement of a catheter or injection into the spinal column (e.g. for epidural or spinal anesthesia or for pain relief):

3. How to take Privenax
Privenax capsules can be used in adults and children aged 8 years or older who are able to swallow the capsules whole.
Follow the instructions for administration of this medicine exactly as indicated by your doctor. If you are unsure, consult your doctor again.
Take this medicine as recommended for the following situations:
Prevention of blood clot formation after knee or hip replacement surgery
The recommended dose is 220 mg once a day(administered in the form of 2 capsules of 110 mg).
If your kidney function is reducedby more than half or if you are 75 years of age or older, the recommended dose is 150 mg once a day(administered in the form of 2 capsules of 75 mg).
If you are using medicines that contain amiodarone, quinidine or verapamil, the recommended dose is 150 mg once a day(administered in the form of 2 capsules of 75 mg).
If you are using medicines that contain verapamil and your kidney function is reducedby more than half, you should be indicated a reduced dose of dabigatran of 75 mgbecause your risk of bleeding may increase.
In both types of surgery, treatment should not be started if there is bleeding at the surgical site. If treatment cannot be started until the day after surgery, dosing should be started with 2 capsules once a day.
After knee replacement surgery
You should start treatment with dabigatran 1-4 hours after surgery, taking a single capsule. After that, you should take 2 capsules once a day for a total of 10 days.
After hip replacement surgery
You should start treatment with dabigatran 1-4 hours after surgery, taking a single capsule. After that, you should take 2 capsules once a day for a total of 28-35 days.
Prevention of stroke or systemic embolism due to blood clot formation in patients with irregular heartbeat and treatment of blood clots in the veins of your legs and lungs, including prevention of recurrence of blood clots in the veins of your legs and lungs
The recommended dose is 300 mg administered in the form of one 150 mg capsule twice a day.
If you are 80 years of age or older, the recommended dose of dabigatran is 220 mg administered in the form of one 110 mg capsule twice a day.
If you are using medicines that contain verapamil, you should be indicated a reduced dose of dabigatran of 220 mg taken in the form of one 110 mg capsule twice a day, because your risk of bleeding may increase.
If you have a potentially higher risk of bleeding, your doctor may decide to prescribe a dose of 220 mg administered in the form of one 110 mg capsule twice a day.
You can continue taking this medicine if you need to restore your normal heartbeat through a procedure called cardioversion. Take dabigatran as indicated by your doctor.
If you have been implanted with a medical device (vascular endoprosthesis) in a blood vessel to keep it open in a procedure called percutaneous coronary intervention with vascular endoprosthesis, you may receive treatment with dabigatran once your doctor has decided that normal blood clotting control has been achieved. Take this medicine as indicated by your doctor.
Treatment of blood clots and prevention of recurrence of blood clots in children
Dabigatran should be taken twice a day, one dose in the morning and one dose in the evening, approximately at the same time every day. The administration interval should be as close as possible to 12 hours.
The recommended dose depends on age and weight. Your doctor will determine the correct dose. Your doctor may adjust the dose during treatment. Continue using all other medicines unless your doctor tells you to stop using any.

If you have any other questions about the use of this medication, ask your doctor or pharmacist.
4. Possible adverse effects
Like all medications, this medication can cause adverse effects, although not all people experience them.
Dabigatran acts on blood coagulation; therefore, most adverse effects are related to signs such as bruising or bleeding. Episodes of major or severe bleeding may occur, which are the most serious adverse effects and can cause disability, be potentially life-threatening, or even cause death. In some cases, these bleedings may not be apparent.
If you experience any episode of bleeding that does not stop on its own or if you experience signs of excessive bleeding (exceptional weakness, fatigue, paleness, dizziness, headache, or unexplained swelling), consult your doctor immediately. Your doctor may decide to keep you under close observation or change your medication.
Inform your doctor immediately if you experience a severe allergic reaction that causes difficulty breathing or dizziness.
