Summary
Ibuprofen taken regularly can interfere with the irreversible platelet inhibition of low-dose aspirin, potentially weakening its cardioprotective effect. The concern is greatest in patients taking aspirin for secondary cardiovascular prevention.
What this interaction means in plain words
Aspirin rectal and Ibuprofen can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.
Why it happens
Ibuprofen competitively occupies the platelet cyclooxygenase-1 site and blocks aspirin's access for acetylation.
What to do
Where ibuprofen is needed, take it at least 30 minutes after or more than 8 hours before immediate-release aspirin, or choose an alternative analgesic. Avoid regular ibuprofen in patients on aspirin for secondary prevention.
