You may have a higher risk of bleeding if you take Pradaxa and:
- are over 75 years old
- have kidney problems
- have stomach or intestine bleeding that is recent or keeps coming back, or you have a stomach ulcer

- aspirin or aspirin containing products
- long-term (chronic) use of non-steroidal anti-inflammatory drugs (NSAIDs)

- clopidogrel (Plavix)
- prasugrel (Effient)
- have certain kidney problems and also take the medicines dronedarone (Multaq) or ketoconazole tablets (Nizoral).
