Gawd knows what they are meant to be called I am just glad I ain't on them.
In the UK anyway your meant to disclose as soon as your on any medication although most don't bother with a course of antibiotics. And in general they are pretty good at keeping us flying even if its under a multicrew only restriction. The AME's tend to get the hump on if you spring something on them during the medical, personally I would fess up and see what happens sooner rather than later.
And you think being on them is a PIA just wait until they have to ween you off them.
