Neosporin, is the brand name for an antibiotic ointment, generic or store brands should be just as effective. The Bound Tree (or anyone of the other ems suppliers should work as well) web site likely has their own brand, cheaper. One could argue either way if it is worth the space or not. If the wound is cleaned well, in the short run the ointment may not be necessary. If medical care is not available in a reasonable amount of time, a very dirty wound or if the person has some other type of medical problem (like diabetes) the ointment may prevent an infection. I would not tie up space in a PSK, but if you have an additional medical kit/bag and you have the space, it could not hurt to include some packages. Keep in mind they will have an expiration date.
