Concomitant NSAID-coumarin use may elevate bleeding risk; leaves open whether this warrants absolute avoidance without randomized confirmation.
Does concomitant use of NSAIDs and coumarin derivatives increase the risk of bleeding complications in patients on coumarin therapy?
Concomitant use of NSAIDs and coumarin derivatives significantly increases the risk of bleeding complications compared to coumarin therapy alone, underscoring the contraindication of their combined use.
Knijff-Dutmer et al. (2003) studied this question.
