Ads
  • For persons with coral snake envenomations threatening life or limb, there are no contraindications to administration of Antivenin. However, administration to persons known to be allergic to horse serum, either by history or as a result of an appropriate sensitivity test, requires careful judgement and considerable experience in the use of antivenoms of equine origin. Healthcare providers must be prepared to manage severe, immediate allergic reactions (anaphylaxis) seen with Antivenins of equine origin.8,9,10,11

    Antivenin should never be administered prophylactically to asymptomatic patients.12
