Why can humans only be treated with antivenom once?
Antivenom cannot reverse the effects of venom once they’ve begun, but it can prevent it from getting worse. In other words, antivenom cannot un-block a channel once it’s already been blocked. Over time, your body will repair the damage caused by the venom, but antivenom can make it a much smaller repair job.
