Patient leaflet - Pradaxa 150 mg hard capsules
1. What Pradaxa is and what it is used for

Pradaxa contains the active substance dabigatran etexilate and belongs to a group of medicines called anticoagulants. It works by blocking a substance in the body which is involved in blood clot formation.
Pradaxa is used in adults to:
- prevent blood clots in the brain (stroke) and other blood vessels in the body if you have a form of irregular heart rhythm called nonvalvular atrial fibrillation and at least one additional risk factor.
- treat blood clots in the veins of your legs and lungs and to prevent blood clots from re-occurring in the vein of your legs and lungs.
Pradaxa is used in children to:
- treat blood clots and to prevent blood clots from reoccurring.
2. What you need to know before you take Pradaxa
Do not take Pradaxa
- if you are allergic to dabigatran etexilate or any of the other ingredients of this medicine (listed in section 6).
- if you have severely reduced kidney function.
- if you are currently bleeding.
- if you have a disease in an organ of the body that increases the risk of serious bleeding (e.g. stomach ulcer, injury or bleeding in the brain, recent surgery of the brain or eyes).
- if you have an increased tendency to bleed. This may be inborn, of unknown cause or due to other medicines.
- if you are taking medicines to prevent blood clotting (e.g. warfarin, rivaroxaban, apixaban or heparin), except when changing anticoagulant treatment, while having a venous or arterial line and you get heparin through this line to keep it open or while your heart beat is being restored to normal by a procedure called catheter ablation for atrial fibrillation.
- if you have a severely reduced liver function or liver disease which could possibly cause death.
- if you are taking oral ketoconazole or itraconazole, medicines to treat fungal infections.
- if you are taking oral cyclosporine, a medicine to prevent organ rejection after transplantation.
- if you are taking dronedarone, a medicine used to treat abnormal heart beat.
- if you are taking a combination product of glecaprevir and pibrentasvir, an antiviral medicine used to treat hepatitis C.
- if you have received an artificial heart valve which requires permanent blood thinning.
Warnings and precautions
Talk to your doctor before taking Pradaxa. You may also need to talk to your doctor during treatment with this medicine if you experience symptoms or if you have to undergo surgery.
Tell your doctor if you have or have had any medical conditions or illnesses, in particular any of those included in the following list:
if you have an increased bleeding risk, such as:
- if you have been recently bleeding.
- if you have had a surgical tissue removal (biopsy) in the past month.
- if you have had a serious injury (e.g. a bone fracture, head injury or any injury requiring surgical treatment).
if you are suffering from an inflammation of the gullet or stomach.
- if you have problems with reflux of gastric juice into the gullet.
- if you are receiving medicines which could increase the risk of bleeding. See ‘Other medicines and Pradaxa’ below.
- if you are taking anti-inflammatory medicines such as diclofenac, ibuprofen, piroxicam.
- if you are suffering from an infection of the heart (bacterial endocarditis).

- if you are older than 75 years.
- if you are an adult patient and weigh 50 kg or less.
- only if used for children: if the child has an infection around or within the brain.
- if you have had a heart attack or if you have been diagnosed with conditions that increase the risk to develop a heart attack.
- if you have a liver disease that is associated with changes in the blood tests. The use of this medicine is not recommended in this case.
Take special care with Pradaxa
if you need to have an operation:
In this case Pradaxa will need to be stopped temporarily due to an increased bleeding risk during and shortly after an operation. It is very important to take Pradaxa before and after the operation exactly at the times you have been told by your doctor.
if an operation involves a catheter or injection into your spinal column (e.g. for epidural or spinal anaesthesia or pain reduction):
- it is very important to take Pradaxa before and after the operation exactly at the times you have been told by your doctor.
- tell your doctor immediately if you get numbness or weakness of your legs or problems with your bowel or bladder after the end of anaesthesia, because urgent care is necessary.
- if you know that you have a disease called antiphospholipid syndrome (a disorder of the immune system that causes an increased risk of blood clots), tell your doctor who will decide if the treatment may need to be changed.

3. How to take Pradaxa
Pradaxa capsules can be used in adults and children aged 8 years or older who are able to swallow the capsules whole. Pradaxa coated granules are available for the treatment of children below 12 years as soon as they are able to swallow soft food.
Always take this medicine exactly as your doctor has told you. Check with your doctor if you are not sure.
Take Pradaxa as recommended for the following conditions:
Prevention of brain or body vessel obstruction by blood clot formation developing after abnormal heart beats and Treatment of blood clots in the veins of your legs and lungs including prevention of blood clots from re-occurring in the vein of your legs and lungs
The recommended dose is 300 mg taken as one 150 mg capsule twice a day.
If you are 80 years or older, the recommended dose is 220 mg taken as one 110 mg capsule twice daily.
If you are taking verapamil containing medicines, you should be treated with a reduced Pradaxa dose of 220 mg taken as one 110 mg capsule twice a day, because your bleeding risk may be increased.
If you have a potentially higher risk for bleeding, your doctor may decide to prescribe a dose of 220 mg taken as one 110 mg capsule twice a day.
You can continue to take this medicine if your heart beat needs to be restored to normal by a procedure called cardioversion or by a procedure called catheter ablation for atrial fibrillation. Take Pradaxa as your physician has told you.
If a medical device (stent) has been deployed in a blood vessel to keep it open in a procedure called percutaneous coronary intervention with stenting, you can be treated with Pradaxa after your physician has decided that normal control of blood coagulation is achieved. Take Pradaxa as your physician has told you.
Treatment of blood clots and prevention of blood clots from reoccurring in children
Pradaxa should be taken twice daily, one dose in the morning and one dose in the evening, at approximately the same time every day. The dosing interval should be as close to 12 hours as possible.
The recommended dose depends on weight and age. Your doctor will determine the correct dose. Your doctor may adjust the dose as treatment progresses. Keep using all other medicines, unless your doctor tells you to stop using any.
Table 1 shows single and total daily Pradaxa doses in milligrams (mg). The doses depend on weight in kilograms (kg) and age in years of the patient.

Do not double a dose to make up for a forgotten dose.
If you stop taking Pradaxa
Take Pradaxa exactly as prescribed. Do not stop taking this medicine without talking to your doctor first, because the risk of developing a blood clot could be higher if you stop treatment too early. Contact your doctor if you experience indigestion after taking Pradaxa.
If you have any further questions on the use of this medicine, ask your doctor or pharmacist.
4. Possible side effects
Like all medicines, this medicine can cause side effects, although not everybody gets them.
Pradaxa affects blood clotting, so most side effects are related to signs such as bruising or bleeding. Major or severe bleeding may occur, these constitute the most serious side effects and, regardless of location, may become disabling, life-threatening or even lead to death. In some cases these bleedings may not be obvious.
If you experience any bleeding event that does not stop by itself or if you experience signs of excessive bleeding (exceptional weakness, tiredness, paleness, dizziness, headache or unexplained swelling) consult your doctor immediately. Your doctor may decide to keep you under closer observation or change your medicine.
Tell your doctor immediately, if you experience a serious allergic reaction which causes difficulty in breathing or dizziness.
