Can you tell me if i could take oxaprozin 600 mg if i am on the blood thinner plavix (clopidogrel) 75 mg?

With caution: They can be used together but the risk of bleeding is increased so the benefit must be weighed against the risk.

NSAID: Oxaprozin is an anti-inflammaory medication which can have synergistic effect with Plavix (clopidogrel) and may lead to increased tendency to bleeding, especially stomach bleeding. Plavix (clopidogrel) should not be combined with any NSAID medication for safety. Please inform your physician that you are taking Plavix (clopidogrel).
