(WASHINGTON POST) Christopher Ingraham — BTG has fought aggressively to keep competitors off the market. A competing product, Anavip, just received FDA approval this year and likely won’t be on the market until late 2018. This lack of competition is one reason why snakebite treatments rack up such huge hospital bills — $55,000. $89,000. $143,000. In May of this year, a snakebit Missouri man died after refusing to seek medical care, saying he couldn’t afford the bill.
