My Kit changes all the time, these are what I always bring though.
For Wounds, Sprains, and Burns I carry: A SAM Splint laid flat on the bottom of my pack, A large Celox Pad, a few bandages some with a clotting agent, few packets of wound seal, Steri-Strips, Burn Jel, Betadine packets, and Neosporin.
Meds: Hydrocodone, Benadryl, Sleeping Pills, Aspirin, Imodium, and few cough drops. If its going to be off trail I bring a tube of anti itch cream.
Blisters: If I get a hotspot then I stop use Flexitol Blistop Blister Spray too kinda freeze the hotspot or let me feet air out a sec. Change to a pair of aired out or dry socks and with boots that breathe no more blisters.
Medicinal scotch or rum.
