While I agree that a small altoids sized PSK has little space for medical supplies, if you can carry some it would be good.<br>Antibiotics - I personally carry cipro 500 x 5. I wouldn't use it unless I'm really desperate and more than a week has gone by without being rescued and the wound I have is becoming more and more infected despite irrigation and cleaning with water. I don't carry antibiotic ointment as it does little to help prevent wound infection. Wound irrigation and drainage are more important. And while cipro has moderate effect on staph Aureus on the skin (which causes most skin infections), it has a much broader spectrum on other organisms (you may not just have a skin infection - think pneumonia....) and is simple to dose and pack in a PSK (unlike cephalexin).<br><br>Analgesia - I carry only plain paracetamol. While severe injuries require more urgent medical attention and better supplies, when you're on your own in the wilderness and are having fever and chills from the infected wound, you'll be glad to have anything that can help you improve the situation so you can tend to the signal fire or lookout for SAR. Pain relief from paracetamol is moderate at best but something is better than nothing.<br><br>Antihistamine - to reduce the effects of any allergic reaction you may suffer from touching / tasting that plant which you thought was edible. While you may argue that if an oral antihistamine can treat the symptoms, its not serious anyway, you may be right. All the same that dose of antihistamine may just stave off a more severe reaction.<br><br>Lomotil - diphenoxylate /atropine - an antidiarrhoeal and antispasmodic. Again to treat any gastrointestinal problem which you may get from drinking that water or half cooked pigeon / squirrel. Any dehydration from diarrhoea in a survival situation is a potentially lethal especially if water is not abundant. Again, abodminal spasms which prevent you from tending that signal fire or look out for SAR could be avoided if you had some of these.<br><br>Band-aids - I agree that some clean rags and duct tape work better if you are cut and bleeding. I carry some mainly for blisters and such. Other wounds are likely to be bigger and band aids would be of no use.<br><br>Anything as strong as Valeron definitely has no place in my kit. I'll have a hard time trying to explain to the powers that be what it's doing in my kit (it has strong potential for abuse by addicts), and I'm a doctor!! All in all, I would also bring along my comprehensive medical kit on the outdoor activities / camps just to be on the safe side!!<br><br>Just my few singapore cents.....<br><br>
