Besides some of the items mentioned, I carry Caladryl, hydrocortisone cream, sudafed, tincture of iodine, and vaseline.

The sudafed comes in handy because if you wake up with a cold, the sudafed will completely dry your nose out and you can hike better. It was originally developed for the astronauts because they couldn't blow their noses while wearing a suit/helmet. You only need two tiny pills for the whole day.

If you aren't in an area with nasty bugs, then the Caladryl and hydrocortisone may be overkill. In the south, they are definitely required carry for me.

The vaseline is for covering dug-in ticks which makes them release, and also doubles as an emergency fuel, medicine for chapped lips, and jock itch or any kind of rash.

While neosporin and a band-aid are useful for cuts, The tincture of iodine is for scrapes and then can be left open to the air.
