I really like those Trauma Kits as well, posted about them one other time. The Adventure Medical version I have is waterproof, compact, has several dressing options, and can always be kept handy, like in a coat pocket, and I strongly hope they will be good for dealing with all major tissue injuries.I noticed a local gun store is stocking a display of Quick Clot Trauma Kits with the First Aid and camping supplies. The kits are only about $20, and I picked one up to keep in my range bag. We had need of one at a recent pistol match when a bullet fragmented on a steel target stand and bounced back to hit a spectator in the neck. One of the RSOs is a paramedic, and we keep the trauma kits in the range first aid kit, so he got the bleeding under control very quickly, and the guy was back shooting the next day. It would have been messier without a fast way to stop the bleeding. Remember the Boy Scout Motto, and Be Prepared. GI1
I support the above- where I am you want a giant tub of insect repellant so there are regional issues- and I would add Providone, which is basically an iodine solution used to sterilize skin surfaces. You can buy the stuff quite cheaply in bulk, then fill rather small Nalgene bottles for light weight carry. It makes every wound colourful, but on the positive side that means you can tell where it is. The only drug I can think of that's actually dangerous after expiry is codeine, which allegedly becomes poisonous. That is of course not counting things that are dangerous through inertness- I'm thinking of antibiotics and insulin, things like that which look as if they should work but will actually make the situation worse.Be careful storing meds. Some of that stuff can go bad prior to their expirations when subjected to trunk-like swings in temperature. Though most often I think drugs past their expiration, "fail gracefully," and just become relatively inert.
Taking a cruise of your local CVS or Sav-On or whatever you have locally, you can get generic drugs for dirt cheap. I made the mistake of buying the mega bottles of a few things and they're a waste of money. Even if you use them constantly, you'll never run through them before they expire--unless you're supplying an entire college football team with ibuprofin. So you figure $20 every 2 years for generics gets you a pretty good supply of basic stuff.
Off the top of my head I'd say some simple basics, though some of this stuff isn't first aid:
ibuprofen--fever, pain, anti-swelling
rubbing alcohol--sterolization, and a futile attempt to teach me to spell
hydrogen peroxide--for that bleach blonde look
listerine--as an antiseptic
petroleum jelly--burns, cuts, healing
sun screen--no use getting sunburn
small thing of bug spray--no use getting west nile
hand sanitizer--does some of the job of rubbing alcohol in like 1/100th the portion size
contact lens solution--if you wear them, you'll need to fight protein build-up
pepto-bismal--diarrhea can kill, or at least kill your underwear
multi-vitamin--supplement any rations, but take cautiously
back-up of any medication you take regularly
Mercurichrome is the one they frowned on....had Mercury in it. I still use Tincture of Iodine.I've also been thinking that it's good to carry come tincture of iodine, the kind used to put on cuts that is mostly frowned upon these days. It's still good for small cuts and also can be uses as a backup, or even a basic, water purfiier. For the best weight-to-usefullness ratio, I try to find max strength 5% solution but mostly only 2.5% is available these days. To remove the iodine afterwards, if you don't like the taste, all you have to do is to add come ascorbic acid powder, ie vitamin C in its pure form (scrape or crush some of those cheap white tablets), and it precipitates right out.
I didn't know that about mercurichrome, just thought it didn't work very well. It was the kid's choice in my day, being painless as opposed to iodine.Mercurichrome is the one they frowned on....had Mercury in it. I still use Tincture of Iodine.
