YouTube Video: Are fish antibiotics safe for humans?

I have begun purchasing fish antibiotics and on one occasion a 200 pound fish VERY similar in size to me took some  – and did not grow gills.

  1. We have been buying fish antibiotics to save in our survival stock for years. I believe that Doc Bones and Nurse Amy said fish medicines were alright for human consumption. I cannot play the video above right now because it is real late and my wife is sleeping. I hope Patriot Nurse says this medicine is “OK”!

  2. It has long been my understanding that the fish meds are EXACTLY the same drug as the Big Pharma prescriptions, for a fraction of the cost. We have our share and have used them with success; we have a variety, because not everyone can take the same things. It is also my understanding that all are good beyond the “fresh date”, except “tetracycline”, which purportedly failed from a scientific test a very long time ago (supposedly produced toxicity in test samples). However, I have also since read that the study from which that very old evidence was extracted was anything but scientific, so, do your homework, and decide for yourself.

    We use sulfamethoxazole and trimethoprim (Bird Sulfa) for a rescue fur who gets UTI (Urinary Tract Infection). Since UTIs are common in women (especially young women) you may want a bottle or two of this in your stock for IHTF medicine.

    Bottom line? It works. Stock up while you can – but DO check those dates before buying, just to be safest.

    Here’s a list of the most commonly recommended; I keep both 250mg and 500mg (children over a certain weight and adults), but you could just double the 250mg for adults:

    Amoxicillin 250 mg (Fish Mox)-not for penicillin allergic
    Ampicillin 250 mg (Fish Cillin)-not for penicillin allergic
    Keflex 250 mg (Fish Flex)
    Metronidazole 250 mg (Fish Zole)
    Penicillin 250 mg (Fish Pen)
    Tetracycline 250 mg (Fish Cycline)
    Ciprofloxacin 250 mg (Fish Flox)
    Doxycycline 100 mg (Bird Biotic)
    Sulfamethoxazole 400 mg / Trimethoprin 80 mg (Bird Sulfa)

    You will find this information at, as well as at “The Patriot Nurse”, of course.

    You can find references to human dosage equivalents at places like

    And while I really appreciate “The Patriot Nurse”, the Doom and Bloom Medical Handbook (newest version) is a MUST HAVE for post-IHTF. But read it before it hits – please!

  3. Wisdom, ServantHeart! If you are going to be caring for folks, you need to know any drug allergies they may have. Agree the Doom and Bloom handbook is a must have on the shelf (and yes, read it as well, don’t just let it gather dust). That will help you to know which antibiotic is best for treating various ailments. Keep in mind that someone allergic to Penecillin will most likely not tolerate amoxicillin or ampicillin either (not always true, but I would err on the side of caution). Also be aware that penecillin allergic often do not tolerate sulfa either. I’m not exactly sure why, but it’s quite common per my experience. I would also suggest, in addition to the fish antibiotics, if you have an old school country vet around, developing a relationship with them as another source of antibiotics. A lot of them stock medication to sell in their practices. And again, they are the same medicines that people take, altho there may need to be some dose adjusting. And they may be useful in helping you to stock and prescription medication you take regularly. My mom’s dog takes the same thyroid medication she does, just at a different dose.

  4. I also want to second something that PN briefly mentioned. DO NOT use antibiotics willynilly. Antibiotics do NOT help with the common cold or any other virus. DO NOT not take the prescribed course, or you will be contributing to antibiotic resistance. Of course, in a disaster situation this might not be avoidable, you may have to ration, or not have enough on hand….but do not treat yourself or others with antibiotics unless you have a clear understanding of how they should properly be used. I also do not advocate treating yourself while we still have halfway decent access to care. Don’t forgo having a primary care doctor. Who knows, they may be like minded and help you to build up a store of your regular prescription medicines (might have to pay out of pocket, but they may be willing to write an extra month’s prescription for you!)

  5. I have used the Amoxycillin (this year), even though I have a regular doctor — there was a time issue and I did not have the luxury of being sick that weekend. I was getting sick on Friday and by Saturday I had a temp so I self-dosed, figuring this might be strep. A 10 day dose and I was fine. For the naysayers, the last time I went to a doctor with symptoms of strep, he didn’t give me a culture, just treated me for strep. “Modern medicine” has gotten VERY stingy, even for those of us who are insured. Wait until Obamacare destroys the health care, then everyone will be stocking their own antibiotics.

    The fish antibiotics are the same as those for humans — check the US Pharmacopeia to prove it. The capsules are same color and have same number assigned to them as those for humans. Compare strengths and you will see they are the same. It is not feasible to manufacture antibiotics for fish/aquatic life when the FDA-approved drugs for humans suffice.

    Do your research and get information for each medication you store so you understand what each treats and why.
