This removes the causative agent and prevents further anticoagulation. Subsequent steps include notifying the provider, administering the reversal agent protamine sulfate as prescribed, and conducting frequent monitoring for signs of shock or intracranial hemorrhage.
Never administer protamine sulfate while the heparin infusion is still running. Always stop the infusion first to avoid worsening the overdose. Monitor for anaphylactic reactions during protamine administration.
