Can tPA be given with heparin?
Introduction: Administering intravenous IV tissue plasminogen activator (tPA) is the recommended standard of care in acute ischemic stroke (AIS), although it is not recommended to administer intravenous thrombolysis with tPA following heparin reversal with protamine sulfate in patients with AIS.
What are the contraindications for giving tPA?
Contraindications
- Significant head trauma or prior stroke in the previous 3 months.
- Symptoms suggest subarachnoid hemorrhage.
- Arterial puncture at a noncompressible site in previous 7 days.
- History of previous intracranial hemorrhage.
- Intracranial neoplasm, AVM, or an aneurysm.

Can heparin and alteplase be given together for MI?
Myocardial Infarction Alteplase may be used in conjunction with heparin and aspirin for the treatment of myocardial infarction. When used for this indication, providers may select one of the following dosing regimens: IV bolus followed by a 90-minute infusion or a 180-minute infusion.
When do I start heparin drip after alteplase for PE?
After alteplase, heparin may be re-initiated several hours later without a bolus. Alteplase may be combined with low molecular-weight heparin (rather than a heparin infusion).
When should I stop heparin before alteplase?
Do not continue infusion beyond 6 hours. Consider heparin at 10 units/kg/hr during alteplase infusion (do not give a heparin loading dose). Start as soon as possible, aiming for several hours of heparin prior to starting alteplase.
When can you give heparin after tPA?

When should you not give alteplase?

Can you give tPA to someone on Coumadin?
This important, large study seems to confirm current guidelines that tPA can be safely administered in acute ischemic stroke patients taking warfarin when the INR is ≤1.7 without any increased risk of sICH.
When do you stop heparin drip for PE?
Heparin can then be stopped when concomitant use with warfarin has achieved an international normalised ratio (INR) of 2-3 for at least 48 hours. In patients with large ileofemoral vein thromboses or major pulmonary embolism, heparin infusion can be continued for up to 10 days.
