With the approval by the U.S. Food and Drug Administration on May 6 of a new antivenom to treat rattlesnake bites, the two poison control centers in Arizona are on track to begin research into the best utilization of snakebite medicines.
The FDA has approved the use of Anavip as a new rattlesnake antivenom. It will join the drug CroFab, which has been the sole antivenom available for purchase since 2000, as a medicine to treat patients who have been bitten by a rattlesnake.
