consider adding clindamycin or metronidazole for GI infections; clinda of course can double for cellulitis. Seems infections run rampant after this stuff.
Zofran/phenergan/compazine for Nausea/vomiting.
Personal scrips, including spare glasses. Personally, if you wear contacts, have a case with some saline already in the cups, and ditch the contacts if you are in a disaster zone. Too much potential for crud to infect your eyes.
Your memory is right - KI for fallout.
Otherwise, I think most of the other meds have been touched upon.
Maybe a bag or 2 of saline, in case dehydration gets the best of someone. Which of course, entails all the set-up equipment as well.
