I've over 50 Antivenoms from legion assassins with me, so the poison isn't a problem for me. I ussually use a flamer against cazadors if they are in bigger groups, it works well.
The only problem I have is if they hit companions just one time, they will die by poison and theres nothing you can do against it.
