I'm taking 2.5 warfarin daily for a clotting disorder. the past week have taken 2 aleve (naproxen) daily for leg pain from a dvt, will this affect my inr?

No: But taking warfarin is not a great idea as the nsaids (including aleve) can affect the lining of the stomach and result in bleeding. I would try some tylenol (acetaminophen) or tramadol.

Unlikely: Usually well tolerated, but checking inr is not a big deal.

Possibly: It could affect your inr but by this point, any effect you might see would be stable. As dr. Wright said, checking an inr wouldn't be a bad idea. There other things to take for pain that are probably a better idea than aleve (naproxen) if you are also taking warfarin as dr. Niazi said. You should also use compression stockings, if you are not already.

Dangerous: It could cause a significant bleeding ulcer. Nsaids are not recommended while taking coumadin (warfarin).
