Not the Right Antidote

Several antivenoms used to help people recover from the bites of saw-scaled vipers—a group of incredibly lethal snakes commonly found in Africa, the Middle East and Asia—don’t work well enough, according to an Australian study.

Snakebite antidotes contain toxins from multiple types of snakes. But researchers found that 4 antivenoms did not work on all venomous toxins from saw-scaled vipers in 9 countries.

Antivenom makers are responding by relabeling their products so it’s clearer they should be used only in certain parts of the world, and by working to develop new, more broadly effective antidotes.
