Nope dont have it confused,
The primary reason for it not being suitable for aircrew is I believe the incidience of sudden nausea.
I do not want to get into a debate about the suitability of medications in a public forum for obvious reasons.
All medications have side effects, and anti-malarials historically have some quite severe ones.
The point I am trying to make is that before you take a medication check up on it, talk to your GP about it or get info on the net.
