Use of both Fab and F(ab ’)2 fragment antivenom in a pediatric patient for treatment of a North American Crotalidae envenomation

Crotalidae envenomation has been managed successfully in emergency departments across the world with antivenom. Over the years, antivenom has evolved and newer agents have been studied with the possibility of eliminating maintenance antivenom therapy. Here we report a patient who had worsening platelet and fibrinogen concentrations, as well as complaints of swelling and pain at the site of a rattlesnake envenomation following an initial dose of F(ab ’) 2 AV (Crotalidae immune F(ab’) 2 (equine) [ANAVIP®]) Crotalidae antivenom.
