I haven't googled yet, but whats a good OTC for antibiotics like penicillin or amoxicillin? In the situation above, you bring your BB back and stop the bleed. But days later infection sets in.
Any antibiotic will be better than nothing. Alcohol, peroxide, Neosporin/antibacterial ointments, bandages to keep the wound covered and protected, etc.
Topical antibacterials are used more often than oral/injected. That's because more people encounter scrapes, cuts, abrasions, bites, scratches, splinters, and so on which are superficial. If you tend to the injury/infection soon enough, topical products are all you need.
When you start getting into internal bacterial infections like in the throat, nose, eye, ear, Lyme Disease, gum disease, pneumonia and similar, obviously an internal medication is indicated. Unfortunately, finding one that's OTC is going to be almost impossible.
The best method I know is to complain of a chronic problem like adult acne, and get a prescription for something like Erythromycin or Tetracycline. You can gradually stockpile some for emergency use. But, the shelf life of these can be relatively short, so look into ways to store them from longer effectiveness.
Erythromycin is an antibiotic used for the treatment of a number of bacterial infections.[1] This includes respiratory tract infections, skin infections, chlamydia infections, pelvic inflammatory disease, and syphilis.[1] It may also be used during pregnancy to prevent Group B streptococcal infection in the newborn,[1] as well as to improve delayed stomach emptying.[3] It can be given intravenously and by mouth.[1] An eye ointment is routinely recommended after delivery to prevent eye infections in the newborn.[4]Tetracycline, sold under various brand names, is an oral antibiotic in the tetracyclines family of medications, used to treat a number of infections,[1] including acne, cholera, brucellosis, plague, malaria, and syphilis.[1]You might find a "natural" means of producing these drugs, too.
Our modern understanding of tetracyclines dates their discovery to 1948, but there
is evidence that early inhabitants of Northeastern Africa consumed tetracycline antibiotics.
Nubian mummies from between 350 and 550 C.E. were found to exhibit patterns of
fluorescence identical with that of modern tetracycline labelled bone.[24]
Tetracycline has a high affinity for calcium and is incorporated into bones during the
active mineralization of hydroxyapatite. When incorporated into bones, tetracycline can
be identified using ultraviolet light.[25]
It is conjectured that the beer brewed at the time was the source of the tetracycline
found in these bones.
