Summary
Naproxen combined with dabigatran increases the risk of clinically significant bleeding, including gastrointestinal hemorrhage. NSAIDs impair platelet function and can injure the gastric mucosa while dabigatran provides anticoagulation.
What this interaction means in plain words
Dabigatran and Naproxen 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 effects of platelet inhibition and direct thrombin inhibition, plus NSAID-related mucosal injury.
What to do
Avoid regular NSAID use in patients on dabigatran and use paracetamol for analgesia where possible. If an NSAID is essential, give the shortest course with gastroprotection and monitor for bleeding and renal function.
What to ask your pharmacist
