What do you give to reverse heparin?

Heparin Antidote

  1. Termination of the IV infusion generally will terminate the anticoagulant effect.
  2. If immediate reversal is required protamine sulfate will result in neutralization of heparin. The dose of protamine is based on the amount of heparin administered in the previous 2 hours using Table 2.
