Advil is a brand name for ibuprofen, a nonsteroidal anti-inflammatory drug (NSAID) used to treat pain and inflammation. According to Drug Patent Watch [1], ibuprofen does not interact with blood thinners. However, the Harvard Health Blog [2] warns that NSAIDs like ibuprofen can increase the risk of bleeding when taken with blood thinners like warfarin, dabigatran, rivaroxaban, and apixaban. The blog suggests that patients taking blood thinners should avoid taking NSAIDs unless their doctor approves it. Similarly, GoodRx [3] advises against taking ibuprofen or other NSAIDs while on blood thinners as they can increase the risk of bleeding.

In conclusion, while ibuprofen does not directly interact with blood thinners, it is recommended that patients taking blood thinners should avoid taking NSAIDs like ibuprofen unless advised by their doctor due to the increased risk of bleeding. It is important to consult with a healthcare provider before taking any medication while on blood thinners.
