Can you mix coumadin with Aleve?

Almost everything interacts with coumadin. Aleve is specifically listed as interacting with coumadin. See your doctor or pharmacist. You can probably mix the two, but you need to pay attention to the effect on PT/INR, and on the short vs long term status of everything you take, so that you can adjust the coumadin dose. You are being monitored, aren't you? Again, see your doctor or pharmacist.
