It is definitely over-inclusive. The idea is to list as many items as I think may be useful. The reader is invited to take the checklist to the store and use it as a guide to stock a hurricane first aid kit. When stores are closed or when it's raining cats and dogs is not the time to find you are out of one of your reliable medicines. Also, remember to rotate the stock from time to time.
Many medicines have expiration dates.
I recommend you store as many of these items as possible in a common plastic fishing tackle box. Such boxes are spacious, have many small compartments, and are easily portable. Sterile gauze pads in several sizes, and especially big sizes. Spend extra and get the ones that are individually wrapped.
