  1. On the comment of why the dosage for a guppy is similar to that of a 180lb human it is because of the dilution effect. The dosage for a human is based upon the size of the patient because once it enters the body the drug is dispursed throughout the whole body and not just where the infection is located. The same is true when adding antibiotics to a fish tank, you need to add enough drug to the container that concentration will be sufficient not matter where the patient is swimming at the moment.

  2. Great Post! I have carefully brought this up with my PCP but he was very reluctant to prescribe anything beyond what I needed for that visit. I was more successful with my dentist when I had an oral surgery and told him I was sensitive to pain. I received the larger dose and antibiotics. I carefully managed the use and have some left over but never enough to last any break in our medical access.

  3. Hi,

    This is Dr. Bones (not Dr. Bob, Jason, lol),

    and we have over 150 articles on medical preparedness on our blog at http://www.doomandbloom.net.

    Regarding the dilution effect, the point is that that dilution effect does not explain why they have chosen exactly the human dosages for the fish antibiotics they market. There is no mathematical equation that says that Amoxicillin 250 or 500 mg exactly dilutes out to the exact dosage a guppy needs. That guppy might live in a 5, 10, or 100 gallon aquarium. Also, all of the other antibioitcs are exactly in human dosage only. This leads me to believe that they come from the same factory lots as the medications that go to human pharmacies.

    Great article, and spot on with your assessment of both the fish supplements as well as the overuse of antibiotics in animals.

    When SHTF, a good supply of antibiotics will be worth more than gold, but better than that, your family and friends may need them and you will be able to help!
    Just keep them stored in a cool place. If there is no cool place, consider burying them in a plastic tube several feet below the surface. That should keep them below 65 degrees. Also, revisit your stockpile every year and order more so the entire lot doesn’t expire at once.

  5. Just “anecdotal hearsay evidence” and worth nothing, in and of itself, but an old acquaintance who worked for a huge pharmaceutical house once mentioned, in passing, “if the caps dont look right, or the packaging is messed up, we ship it to the veterinary side – cheaper than dumping it, now that EPA is watching.”

  6. aquaticpharmacy[dot]com has an even wider variety available, including azithromycin, ciprofloxacin, and clindamycin. No affiliation, just saying. Knowledge in selecting one (?) for the patient is the key, there’s some good recommendations on antibiotic selection by infected region or type of injury on the web. A PDR is nice, but probably overkill since we’re only talking about maybe a dozen different drugs. drugs[dot]com info would be enough, unless you want to understand the molecular structure and the method of action for each (and a good wiki will have that). Print out the info for each, along with antibiotic selection charts/guides/tables from hospitals and universities in case you can’t get to the web. Here’s a couple decent (I think) places to start:
