Summary
Aspirin inhibits platelet function and can injure the gastrointestinal mucosa, so adding it to dabigatran increases the risk of major and gastrointestinal bleeding. Rectal administration still gives systemic platelet inhibition.
What this interaction means in plain words
Aspirin rectal and Dabigatran etexilate 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 hemostatic impairment: irreversible COX-1 platelet inhibition plus direct thrombin inhibition.
What to do
Use together only when there is a clear indication such as recent coronary stent, and reassess the need regularly. Monitor for bleeding and consider gastroprotection.
What to ask your pharmacist
