We stockpile shelf-stable long-term storage foods as well as basic medical supplies, reference books, gear, and weapons as a means of ensuring, not only survival, but that we can continue to live as close to a normal life as possible, even in much harsher times. In its bones, it boils down to self-sufficiency.
That said, it is not lost on us that one of the linchpins of modern medicine, namely antibiotics, is a huge stumbling block to any who wish to live a life independent of the system. Even in a world where you've prepared in nearly every conceivable way (including going so far as to procure Mil-Spec field-surgery kits), a simple cut can carry the risk of getting infected and killing you. Likewise with simple illnesses. Prior to the advent of antibiotics, perfectly healthy people died from what are now easily-treatable ailments.
Which beings me to the purpose of this article.
The stockpiling of medications is tricky, to put it mildly. OTC drugs are easy-to-acquire and cheap; prescription drugs... not so much. I have known many Preppers who have lied to Doctors, claiming to be about to embark on an overseas trip by boat, etc., and talked them into writing a script for a few courses of basic antibiotics. Beyond that, there isn't really a choice.
Before I go any further, I also need to remind you that I am not a medical professional and I am not attempting to give you any medical advice. I am simply passing along what I have found via research. What you do or do not do with that knowledge is your own business and has no bearing on me; nor do I accept any responsibility for your actions. Also, you need to understand that I'm not advocating the use of these drugs now, but, rather in situations where medical attention is not available and is unlikely to become available any time soon.
Now that the disclaimer is out of the way, I can tell you this: the antibiotics sold without a prescription (or any other documentation) for treating ailments in fish is the exact same stuff as what your Doctor prescribes you.
I won't vouch for particular brands, but, if you look at the ingredients for a bottle of FISH-MOX, and the sole ingredient is amoxicillin, then what you're holding in your hand is a bottle of amoxicillin. Period. The only difference between it and what you normally take is the packaging, the much higher price, all the red tape, and a different rate of taxation. If there are a lot of other ingredients, do your due diligence before taking it, but, if it only has the one active ingredient, then that is the only active ingredient.
Also, don't sweat the expiration dates. The FDA requires Big Pharma to place expiration dates on drugs as an indication of how long they will vouch for its potency, not when it "goes bad." The only drug for which this does not hold true is tetracycline (FISH-CYCLINE for our purposes), which can become toxic after its expiration date, so be careful.
