Where to start....
No, bandaids don't fix much, but keep them anyway. Including a couple of the fingertip and knuckle ones.
Pads and rollers are good. Add a couple of the cheapest, unscented maxipads you can find, as bulk dressings.
A good pair of shears. Good tweezers.
Ex-lax... yeah, not that much. You'll need it less than you need the immodium in most cases.
Benydril, sudafed (the real stuff).
Gana mentioned the non-analgesic properties of the three major OTC pain killers. Aspirin is an acid and too much will burn a hole in the lining of your stomach eventually. Too much acetaminophen can do damage to your liver. Too much ibuprofen I don't know about- probably does something like turn you purple or triggers spontaneous gender reassignment. Long story short, don't abuse the stuff, and the three all have their own advantages. Learn them, carry all three.
Nitrile (not latex) gloves.
If you are CPR certified and this going to be carried, add a pocket mask; if not certified, fix that problem. If you are looking at this as part of BOB, don't worry about the mask.
A LITTLE duct tape, no more than ten feet rolled on a coffee stirrer or bamboo skewer.
A couple of gallon-sized freezer bags (multipurpose item, but mainly as a litter bag for potentially contaminated stuff) and a Sharpie (I put some notes on people's foreheads, and not just T-and-time- if you lose that, you're pretty well fucked). A small note pad, and a pencil. This is a good place for a small flashlight, and maybe a spare SAK, multitool or pocket knife.
A container. I like rigid ones, but waterproof.
"Even if it's only the handful of people I happen to meet on the street or in my home, I can still protect them with one sword."
When a man go no longer speak without malice intended lest he cause offense, that is when truth starts to die.
There are three kinds of man- Man the Toolmaker, Man the Tool User, and man the tool.
