Summary
Fenbufen is an NSAID that inhibits platelet function and can cause gastrointestinal injury. With heparin the risk of bleeding is increased.
What this interaction means in plain words
Fenbufen and Heparin 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
NSAID-induced platelet inhibition and mucosal injury add to the anticoagulant effect of heparin.
What to do
Avoid if possible and use an alternative analgesic such as paracetamol. If necessary, monitor for bleeding and hemoglobin and consider gastroprotection.
