What this interaction means in plain words
Aspirin / citric acid / sodium bicarbonate 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
