Not really: All medications used after an ischemic stroke (cholesterol plaque rupture causing an interruption in blood flow) are treated with blood thinners. Some people are more sensitive to certain ones, so if you've had a GI bleed while on Plavix (clopidogrel), (clopidogrel) then talk to your neurologist.
