Summary
Diclofenac adds to the bleeding risk of dabigatran by impairing platelet function and irritating the gastric mucosa. Serious gastrointestinal and other hemorrhage may result.
What this interaction means in plain words
Dabigatran and Diclofenac can interact in a way that may be serious. Using them together is sometimes necessary, but it needs a deliberate decision by the prescriber, a plan for monitoring, and clear advice on the warning signs to watch for.
Why it happens
Additive pharmacodynamic effect: anticoagulation by direct thrombin inhibition plus NSAID platelet inhibition and mucosal injury.
What to do
Avoid routine concomitant use and choose non-NSAID analgesia such as paracetamol where possible. If unavoidable, use the shortest course, consider gastroprotection and monitor for bleeding and hemoglobin.
