Summary
Ibuprofen inhibits platelet function and can injure the gastric mucosa, which adds to the bleeding tendency produced by heparin. The combination raises the risk of gastrointestinal and other clinically significant hemorrhage.
What this interaction means in plain words
Heparin and Ibuprofen 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.
Heparin belongs to Cardiovascular; Ibuprofen belongs to Musculoskeletal.
Why it happens
Additive pharmacodynamic effect: NSAID-induced platelet inhibition and mucosal injury combined with heparin anticoagulation.
What to do
Avoid combining where possible and choose paracetamol (acetaminophen) for analgesia. If both are needed, monitor for bleeding, hemoglobin and aPTT/anti-Xa and consider gastroprotection.
