  • NOTE - in stroke, do not give aspirin until 24 hours after giving tPA, as ASA with tPA does not improve outcomes and increases bleed risk[1]
  • Do not give acutely heparin (or any anticoagulation) if giving tPA[2]


  • 0.9mg/kg IV (max 90mg total)
    • 10% of dose is administered as bolus; rest is given over 60min
  • Neuro check Q15min x 2hr
  • No anticoagulation/antiplatelets x 24hr
  • Blood pressure (keep SBP <180, DBP <105)

If SBP is >180-230 or DBP is >120:

  • Nicardipine 5 mg/hr by slow infusion (50 mL/hr) initially; may be increased by 2.5 mg/hr every 15 minutes; not to exceed 15 mg/hr OR
  • Labetalol 10mg IV over 1–2 min; repeat dose q10–20min up to 300mg max OR
  • Labetalol 10mg IV followed by infusion at 2–8 mg/min

If BP not controlled by above measures:

  • Nitroprusside 0.5–10mcg/kg/min
  • Continuous arterial monitoring advised
  • Use with caution in patients with hepatic or renal insufficiency
