I took a small medicine bottle (about the size of shotgun shell), made a four-way divider out of thin cardboard, and then put in Immodium, Tylenol, Motrin, and Benadryl. I have put the names of the meds, their colors, and the basic dosing on a label. The question is whether it would pass the LE test? I guess it would depend on the officer. Considering it is in a backpack with other specific gear, maybe. For on person carry I would stick with single packs.
