Have you ever been, errr, incapacitated by a... I dunno... severe diarhea? LOL! <img src="/images/graemlins/cool.gif" alt="" /> If i'm seriously incapacitated, I doubt that someone will dig in my messenger bag and open up my first aid kit in search for THE pill...
I understand your point though. It would be easy to use a marker and write down ADVL, BDRL, TYLN, on the packages... Hey, that becomes a guessing game too! <img src="/images/graemlins/smile.gif" alt="" />
EDIT : Here's another pic I took. You can see that I wrapped coins, batteries, a tinder stick and cotton swabs too!
