Small amounts of medications such as antibiotics could be procured by anyone who is willing to tell their physician that they are going out of the country and would like to avoid “Montezuma’s Revenge”. Ask them for Tamiflu for viral illness and Z-packs, Amoxicillin or Keflex for bacterial diarrhea. Stockpiling of these antibiotics is more of a problem. After searching far and wide, I have come across the best option for the prepper: Aquarium Fish antibiotics.
For evaluation purposes (and because I am an aquarium hobbyist), I decided to purchase online a variety of these products and found them to be identical (unlike some Dog and Cat medications) to those used to treat humans with a doctor’s prescription. I was able to purchase them without any demand for medical licensure, etc. The drugs are listed below and the bottles list the antibiotic as the sole ingredient. They are:
* FISH-MOX (amoxicillin 250mg)
* FISH_MOX FORTE (amoxicillin 500mg)
* FISH-CILLIN (ampicillin 250mg)
* FISH-FLEX Keflex 250mg)
* FISH-FLEX FORTE (Keflex 500mg)
* FISH-ZOLE (metronidazole 250mg)
* FISH-PEN (penicillin 250mg)
* FISH-PEN FORTE (penicillin 500mg)
* FISH-CYCLINE (tetracycline 250mg)
These medications are available usually in plastic bottles of 100 tablets for much less than the same prescription medication at the pharmacy (some come in bottles of 30 tablets). The dosages are similar to that used in humans, and are taken two to four times a day, depending on the drug. The 500mg dosage is probably more effective in larger individuals. Of course, anyone could be allergic to one or another of these antibiotics, but not all of them. (Note that there is a 10% cross-reactivity between "-cillin" drugs and Keflex, meaning that, if you are allergic to Penicillin, you could also be allergic to Keflex). FISH-ZOLE is an antibiotic that also kills some protozoa that cause dysentery.
NOTE: It should be emphasized that FISH-CYCLINE [and other tetracycline antibiotics of various names] can become toxic after its expiration date, unlike most of the other medications listed. So consider acquiring the other ones listed, first.
