Before administrating any antivenom, medications and equipment for the treatment of anaphylaxis should be immediately available, including intravenous fluids, epinephrine, and intubation equipment.

Antivenoms for envenoming by Latrodectus spp. Two agents are available in the United States for treatment of pit viper envenomation: Crotalidae Polyvalent Immune Fab (Ovine), which goes by the trade name CroFab, and Antivenin Crotalidae Polyvalent (Equine).24 CroFab is manufactured by Protherics Inc. (Nashville, TN) and distributed by Fougera (Melville, NY; 1-800-231-0206). The molecular size of Fab is approximately 50kDa, making it smaller than F(ab')2 which is approximately 110kDa. Another pediatric case featured consumptive coagulopathy and hemorrhagic diathesis (Akimoto et al., 1991). David A Warrell, in Hunter's Tropical Medicine and Emerging Infectious Disease (Ninth Edition), 2013. You may be given an injection to help protect you from tetanus. No skin test is recommended for CroFab, although manufacturers of many other types of antivenom recommend skin testing. The fragment antigen binding, or Fab, is the selective antigen binding region. Before injection of Anti-Snake Venom Serum, history of prior injections of serum (e.g. Both rabbit- and goat-derived antivenoms were clinically effective, and none of the patients developed antivenom reactions. Antivenom should be given promptly for best results, although it may have benefit for days to weeks after an envenomation.
