>> I worry about infection as well, but it will take some time for an infection develop and most likely you would be off the trail by the time that happens. <<
You might want to re-think that one. I always carry a prescription antibiotic ever since I had a problem on a 4 day trip. I noticed that a small cut on my shin went bad on the second day of my trip. Didn't even notice the cut the first day, it was insignificant, so it didn't get covered or treated. Second day it started to swell and feel hot and by the third day I had a serious infection underway.
The surprise to me was that by the third day, my ankle was swollen and I could hardly get my hiking shoe on and the last ten miles on the final (4th) day was difficult. The doctor said the infection in my shin was causing fluid to pool in my foot and ankle which is why I was having so much trouble. He said I was lucky I didn't wait another day as I may have been in serious trouble.
So a half ounce prescription provides some additional treatment for infected blisters, cuts and bites if they happen to go bad. Ask the pharmacist to write the expiration date on the prescription. Most of the ones I buy are good for two years.
The other thing I've added recently is more band-aids. Don't go cheap here (weight wise) because a few lacerations over the period of a week long trip can use up a lot of band-aids if you really need to keep the wound clean and covered.
