The website drugpatentwatch.com states that Advil (ibuprofen) may increase the risk of bleeding when used with anticoagulants such as Pradaxa. Drugs.com also warns that taking these two medications together may increase the risk of bleeding. The website suggests that patients should talk to their doctor before taking Advil or any other NSAID while on Pradaxa.

An article on health.harvard.edu also warns against the combination of blood thinners and NSAIDs. The article states that NSAIDs can interfere with the blood-thinning effects of anticoagulants, leading to an increased risk of blood clots. The article also notes that NSAIDs can cause stomach bleeding, which can be especially dangerous for patients taking blood thinners.

In conclusion, combining Advil and Pradaxa can increase the risk of bleeding and should be avoided unless directed by a doctor. Patients should talk to their doctor before taking Advil or any other NSAID while on Pradaxa. It is important to always follow the advice of a healthcare professional when taking multiple medications.
