For the benefit of those trying to avoid misinformation, the answer is no.

So, I recently posted chapter six of my lost novel, The Dream King's Daughter. This one required more editing than the other chapters because in my initial draft, I featured a scene where the villain Salvadore tries to capture Aurora by surrounding her with mysteriously controlled rattlesnakes. In trying to bargain for Aurora to come quietly, he holds up a syringe of anti-venom, telling her that if she doesn't come quietly, he'll force the issue by having the rattlesnakes bite her, leaving her at his mercy with his anti-venom.
In the original draft, I resolved the standoff by having Aurora manage to control the rattlesnakes herself through her strange powers and send them away. When Salvadore attacks her physically, she's able to stab him with his own syringe, at which point the anti-venom sends him into anaphylactic shock. While he begs for help, she coldly tells him to get his own snakes to bite him before she runs away.
As you can see, when I wrote this story, I had no clue how anti-venom worked, but I didn't let that stop me. I find it somewhat hilarious now that my vision of anti-venom was similar to that of anti-matter. Venom and anti-venom: they cancel each other out, don't they? So, if you get too much of one without the other, then we've got a problem, surely!
As I said before: no.
This would not have survived a proper edit, and it highlights why every book should get a proper edit, whether they're published traditionally or independently. I was fortunate to realize that I was operating with inadequate knowledge (thanks to new knowledge gained through my ability to pick up random trivia over the years). It did leave me with the challenge of finding a new resolution to Salvadore's attack. Fortunately, I'd happened to hear about the Narcisse Snake Dens and, wanting to keep the snake motif, came up with a solution that, frankly, feels a little scarier, as it shows off more of Aurora's powers earlier.
