- if you have a liver disease that is associated with changes in the blood tests, the use of Pradaxa is not recommended.
- if you have an increased bleeding risk, as could be the case in the following situations: 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 receiving treatments which could increase the risk of bleeding. if you are taking anti-inflammatory medicines. if you are suffering from an infection of the heart (bacterial endocarditis). if you have a moderately impaired kidney function. Pradaxa should not be used in children.
