Second, I've never taken, nor been told to, "anti-nerve"
agents. The only time you take these is when you've been exposed to a nerve
agent.

There are also Nerve Agent Pre-treatment System (NAPS) tablets which are
taken in anticipation of exposure to cholinesterase inhibitors (nerve
gases, organophosphorous insecticides and so on) - these increase your
resistance to the compounds and buy you more time to mask up, seal up
and grab a Combopen.

I don't believe they're issued to aircrew, though, which would be why
you haven't come across them.
