Because heparin, aspirin, or TNKase may cause bleeding complications, carefully monitor for bleeding, especially at arterial puncture sites.
Should serious bleeding that is not controlled by local pressure occur, discontinue any concomitant heparin or antiplatelet agents immediately and treat appropriately.
Aspirin and heparin have been administered concomitantly with and following administration of TNKase in the management of acute myocardial infarction, but the concomitant administration of heparin and aspirin with and following administration of TNKase for the treatment of acute ischemic stroke during the first 24 hours after symptom onset has not been investigated.
