CroFab is composed of several monovalent Fab (fragment antigen-binding) proteins derived from the blood of sheep immunized with one of four snake venoms: Crotalus atrox (western diamondback rattlesnake), Crotalus adamanteus (Eastern diamondback rattlesnake), Crotalus scutulatus (Mojave rattlesnake), or Agkistrodon piscivorus (cottonmouth or ...
CroFab antivenin has been used successfully to treat Osage copperhead bites, although a lack of complete cross-tolerance requires careful administration and close supervision during the full course of treatment to ensure that the lowest effective dose is administered (a lower dose would not fully treat the envenomation, and a higher dose may be ...
Snake antivenom is a medication made up of antibodies used to treat snake bites by venomous snakes. [1] It is a type of antivenom.. It is a biological product that typically consists of venom neutralizing antibodies derived from a host animal, such as a horse or sheep.
However, CroFab, which makes use of the venom from the cottonmouth (Agkistrodon piscivorus), can be used in cases of a severe envenomation. Gallery.
The antivenom CroFab is used to treat copperhead envenomations that demonstrate localized or systemic reactions to the venom. As many copperhead bites can be dry (no envenomation), CroFab is not given in the absence of a reaction (such as swelling) due to the risk of complications of an allergic reaction to the treatment.

Structure of a Fab with light and heavy chains. The fragment antigen-binding region (Fab region) is a region on an antibody that binds to antigens.It is composed of one constant and one variable domain of each of the heavy and the light chain.
Crofab is the antivenom developed to treat the bite of North American pit vipers. [60] These are not effective against coral snake envenomation, which requires a specific antivenom to their neurotoxic venom. The situation is even more complex in countries such as India, with its rich mix of vipers (Viperidae) and highly neurotoxic cobras and ...
Crotalus scutulatus is known commonly as the Mohave Rattlesnake. [3] [4] Other common English names include Mojave Rattlesnake [5] [6] and, referring specifically to the nominate (northern) subspecies: Northern Mohave Rattlesnake [4] and Mojave Green Rattlesnake, [7] [5] the latter name commonly shortened to the more colloquial “Mojave green”.
