Fish Antibiotics For Humans: A Safe Option For Your Survival Kit?

Fish Antibiotics For Humans

There has been a lot of buzz lately among disaster preparedness blogs and forums about the idea of stocking up on fish antibiotics for humans in the event that there is a disaster or bug out situation and normal medical channels such as doctors, pharmacies, and hospitals are not functioning.

In this guide, we will examine the safety and feasibility of this option as well as look at some other important factors to consider.

Fish Antibiotics For Humans

The topic of Fish Antibiotics For Humans is a hot issue because some survival perparedness-minded people believe that fish antibiotics are interchangeable with normal doctor prescribed medicines and are a good addition to a survival kit or bug out bag.

Doctor prescribed medications can be hard stock up on so some these individuals are attempting to source an alternative that:

  1. Is effective for curing infections in humans
  2. Is readily available to ordinary people
  3. Is available in larger quantities than the single doses that are normally prescribed

Are fish antibiotics for humans safe?

First off, if you are considering this or any other medical related option, you should perform whatever research you deem necessary AND talk to a doctor. Don’t just take this article as you main resource, the author is not a doctor and does not dispense medical advice.

To answer the question of the safety of fish antibiotics for humans, we must first consider the following factors:

  1. What are the ingredients of Fish Antibiotics vs Human Antibiotics?
  2. What are the dosages offered?

I have researched some common brands of fish antibiotics and created this table to help share the information:

Fish Antibiotic NameActive Ingredient and Dosage
Fin Mox ForteAmoxicillin
Fin Flex ForteCephalexin
Fin Flox ForteCiprofloxacin
Fin Pen FortePenicillin

So, if someone was interested in acquiring some fish antibiotics for humans, they can see that these readily available medicines appear to be both the same ingredient and in many cases the same dosage as those offered to humans from pharmacies.

Other Factors To Consider When Researching Fish Antibiotics For Humans

1. Does the fish antibiotic have only 1 ingredient – The last thing anyone wants is to buy and take one of these products that also includes a fish health supplement in it that has not been used by humans. Make sure before you buy that the only ingredient in the capsules is the antibiotic that you want such as:

  • Amoxicillin
  • Cephalexin
  • Metronidazole
  • Ciprofloxacin
  • Penicillin
  • Ampicillin

2. Make sure that the dosages are appropriate to what is recommended by a doctor or a well respected resource such as

3. Store antibiotics properly – These medications should be kept in a cool, dark place with the original seal intact until needed. It is also essential to monitor the expiration date if each bottle and discard and replace any that are out of date.

4. Be aware of allergies – A small segment of the population is allergic to Penicillin and its derivative medicines. Be aware of all medical allergies for anyone you are making a Bug Out Plan for.

5. The rise of antibiotic resistant bacteria in modern society is a major threat to modern medicine. The frequent use of antibiotics in both humans and animals has accelerated this trend. Best practice is to use these drugs only when necessary.

Where Can I Buy Fish Antibiotics For Humans?

Because this is typically administered to fish, there are currently no prescription requirements that this author is aware of (check your local laws).

Without this constraint you will find that fish antibiotics can easily be purchased both from Amazon. Refer to the chart above and click the product name to see it on Amazon.

For further analysis of the topic of fish antibiotics for humans, check out this video by Dr Joseph Alton, author of the excellent book The Doom And Bloom Survival Medicine Handbook and owner of the Doom and Bloom Blog.


It appears that fish antibiotics for humans is a low risk proposition and would be available to be added to a well stocked list of Bug Out Bag Essentials or survival kit. As always, consult with a medical professional before taking ANY medications and conduct your own research before purchasing these products.

  1. Please, also be aware of side effects when using these antibiotics as well as knowing which type of infections they treat. Antibiotics don’t work on all bacteria. Plus, there are some pretty serious side effects using metronidazole with any thing containing alcohol, including mouthwash, perfumes, or hand sanitizers. Also, ciprofloxacin can cause ligament and tendon damage. There’s a reason they require a prescription for human use.

      1. I’ve used Fish Mox 500 mg several times instead of paying to go to doctor. They have Always worked, and helped the problem i had. From UTI, access tooth, sinus infection, and so on. I have Multiple Sclerosis and Cancer as well, no problems taking them. However I will say I believe they are Weaker than regular antibiotics, so sometimes I just take 2 instead of 1.

        1. I discovered these antibiotics when I was looking for a online vet for one of the many animals I rescue and rehome so I could obtain antibiotics. I found these and decided they were worth the risk. They have been a God send! I could not afford to take all these animals to the vet. I open the capsules and disolve them in liquid. If it is a 250 mg capsule, I put in 12 equal parts liquid and use one part per dosage, 2 doses per day on most of the rescues , as most of the animals have been 3 to 5 lbs, A little more for larger ones. The smaller animals generally take up to 25mgs a day the larger ones a bit more. These antibiotics have cleared up many infections. I employ my common sense and so far I haven’t had any problems with them.
          I soon started using them for my family and myself and they work great.

    1. I had the Achilles’ tendon almost rupture from CIPRO who knew??? Great point, during a catastrophe it could go from bad to worse with an allergic reaction!

      1. I carry the MTHFR genes and cant take this. Cipro caused bad nerve damage to me. If anyone is a carrier of the MTHFR gene mutations…I would not recommend it. Just wanted to toss that info out there for anyone to research.

        1. Cipro has many potentially damaging side effects. This has nothing to do with it being for fish. That is with all Cipro including doctor prescribed. You need to know what your taking, what your taking it for, proper amounts and duration. You also need to look up it’s interactions with other drugs/medications and with pre-existing medical conditions.

      2. That is a common side effect of Cipro, not an allergic reaction. Cipro is never prescribed to runners, for instance, for that reason.

    2. ALSO:
      So people are gonna ‘stock up’ on meds?
      Sounds great…but..

      Amoxicillin capsules and tablets have an expiry of around 2 years and, provided they are stored as recommended and in the original packaging, there will be a small lee way of safety if used beyond expiry

      1. No, only the refrigerated version expires in 2 years. 98% off medications do not “expire” they only get weaker.

      2. I have used Fish Mox over several years off and on for various reasons. It always works in a week or so and saves me a trip to the doctor. I’ll keep using as long as I can find it. Just today ordered a new bottle. Was hard to find. LOL.

      1. That is correct, but it’s essential to note that not all antibiotics work on all bacteria. You want to do your research to determine what’s effective against the presenting signs and symptoms, if a lab culture and sensitivity test is not available. In extreme conditions where you determine that whatever the outcome, trying something and having bad or no effects is better than doing nothing, reach for an antibiotic that is “broad- spectrum,” like amoxicillin.

    3. Yeah, the reason they “require” prescription is this $$$$$$$$$$$, that’s all. The gate keepers of our health, are now in control of these pharmaceuticals, but that wasn’t always the case and people were generally healthier. Medical freedom, results in better outcomes. The only reason people are turning to “fish antibiotics” and other drugs, is because doctors refuse to prescribe the human equivalent to their patients. If I have COVID and my doctor refuses to prescribe me a drug, that is saving people’s lives around the world, attested by many doctors and former patients treated with these drugs, then I will be forced to buy the animal version of the drug. That’s how tyranny forces people to do, they end up taking fish antibiotics.

      1. Money is certainly part of it, but I have to disagree. The real problem is idiots will eat them like candy and pop them for any little itch, sniffle, cut or scratch without seeking proper medical attention. I’ve used fish anti-biotic several times over the years, but only when I know what I have and what to use. Antibiotics can be very dangerous if abused, taken in wrong amounts or mixed with other medications. They can make matters worse if you have pre-existing medical problems such as bad kidneys.

      2. I was tested and was positive for covid. Started taking fishbiotic penicillin 250 and I’m feeling 100 percent better after 6 days. Took it cause the doctor wouldn’t give me anything but advice to rest and plenty of liquid. So I took the pills 💊 and had plenty of vitamin c and zinc intake. All good now

    4. Yes and that reason is because the government/FDA wants to control everything especially something as powerful as medication it’s not for your safety it’s just simply control they care about.

    1. Thanks for the suggestion Debbie. Fish meds are a last resort, only if you can’t get some prescribed by a doctor. That being said, they are frequently identical to those prescribed to humans.

      1. I use 500 fish mox for sinus infections and I was dating a cancer Dr and checked with him and he said they were fine. He said they say NOT FOR HUMAN CONSUPTION so people (like me! lol) don’t self medicate . I have gotten sinus infections most of my life so I know what to do for them I just can’t afford the dr visit and getting 100 500mg capsules for a little over $30 is the cheapest way for me to get what I need. I have done this over 10 years, they work, no side effects

        1. I have read enough reviews to see, if your DR can’t prescribe antibiotics (in my case), purchased Thomas Labs Amox online and will have delivered. Have had a sinus infection, along with bronchitis since Thanksgiving and need to get this zapped out of my system. Mind you, I’m in the Public sector with my career, so I need to be in top shape. Hadn’t been sick in over 8 years, so I had a good run, until now. Will start taking when I receive this week.

          1. Janis Joplin feel over dead, self medicating!
            Also Elvis Presle.
            Use very sparingly, only during an economic collapse.

          2. David!!! TRY OPIATES, ALCOHOL, & BENZOS! LMAOOO!!! NOT Antibiotics! Good grief some people!

        2. Thanks for the review, I also suffer from sinus infection every year. My Dr just wants it to run it’s course but I always return to get meds.

          1. Janis Joplin, was doing it as an escape. Elvis died due to a very serious brain injury that he never fully recovered from, and as taking uppers and downers. It is ok to take one or the other but not both as it puts severe stress on the heart and other organs. Him taking those things his death and weight did not come as a surprise. He was a good man that cared about people, but was over prescribed medications. One thing that people overlook is that most often they have to do research and find out what medications can help and hurt all of the conditions that they have. Doctors do make mistakes, and now days with people seeing a dozen or more doctors and not one looking over all the medications does lead to problems. I have had doctors prescribe the wrong medications for me, and refuse to prescribe the correct ones because they do not get gifts from the makers if they prescribe anything that I would see as safe for me.

        3. I have taken the Amoxicillin (500 mg x 3 per day) on two separate illnesses. It knocked out the infection twice,very quickly. I also am prone to getting sinus infections. I get them like clockwork, twice a year. I usually can’t overcome them with over the counter medicines. With my new insurance, which sucks, a simple office visit to my doctor is $109 after the negotiated price with my insurance company. And that’s before I would even pay for the medicine at the pharmacy.

          1. I used to get sinus infections all the time as well. Try swishing cold compressed coconut oil for 20 minutes a day. I did this when I felt one coming on for about 3-5 days. I did this for about a year and haven’t had one since, that was 5 years ago. If they it ever comes back I would go directly back to it. No need for medication! Its called oil pulling. Makes your teeth whiter too!

          1. Amazon, and anything you need.. Research your antibiotics before you buy! THOMAS LABS ONLY!

        4. This is a sensible comment about the use of medicine that special interests (the health “care” bureaucracy, PMA and practitioners) do NOT want the public to know. I am certain that with the same active ingredient in the same amount as the human product, the results should be the same. This also applies to medicines bought from foreign sources. “Advice” to the contrary, especially in the form of veiled threats and attempts to instill fear in users, is nothing less than brainwashing of the public to prevent its thinking and acting on its own.

      2. They are the exact same product therefore it’s ridiculous to say the FDA does not regulate them because they are not made any differently so if they regulate some pills they are regulating all of them.

        1. It’s ok in an emergency but be aware of the following.
          1. You must still get dental treatment or the problem will return.
          2. The dentist cannot and should not work on your teeth while you are on antibiotics ( very dangerous) so you will need to inform the dentist and do dental work/repair immediately after you finish antibiotic.

    2. First off, thank you for the link. I went to this site & read the article, & I must say it is VERY one sided. The article is (to me) bias & does not put forth counter-arguments. Now I live in Canada, & thus do not have to worry about the costs of my meds (as they are free to me), but in the USA, the average citizen (w/o health care) pays obscene costs for their meds (& thus I can understand why someone would currently take them, as maybe this person can afford the $50.00s for a bottle of fish antibiotics, vs. the $500.00 a bottle for human antibiotics). As with other articles concerning the taking of animal antibiotics, NO ONE (worth their salt) is saying take animal antibiotics first vs. taking human antibiotics, but are saying (generally) if you do not have access to human antibiotics (due to costs, etc) during a SHTF scenario, then take animal antibiotics. Yes there can be ‘bad’ animal antibiotics out there, as well as ‘bad’ human meds (i.e., corn starch vs. what you thought was, say, Penicillin, & how some companies in China sell fake human meds), BUT if you are faced with the prospect of say, a loved one dying if they are not given antibiotics, then YOU WILL give them whatever you have. As something is better than nothing. Thoughts?

  2. I have taken the Thomas Labs Amox many times for respiratory infections and they work. No side effects or other problem; but I have no allergies either. I’ve also taken Cephalexin without any issues for minor infections with no issues. These are available at vet supply houses. I have also noted the capsule markings and packaging are identical to what is found in the pharmaceutical documents . I Keep them in the freezer.

  3. I usually get 500 mg of Fish Mox to keep around for my chronic sinus infections as well as for upper resp infections in my feral cats. Have been using this over 10 years and they work just as well as a presc the Dr would give you

    1. Please let me know how you get on? I’ve had a chest infection and ear infection for nearly seven weeks and will only give ear drops.

  4. Well I’ve got some coming for a sinus infection I can’t get rid of. The most important thing to know is how much to take and for how long. Swim’s son is a doctor and he recommends 500 mg twice a day for 5/7 days. Make sure you take the entire dose.

  5. That depends on the severity and type of infection. Usually children will require 125/250mg amoxicillin and adults 500mg. So if the capsule is 500mg then it will be one capsule for an adult.

  6. I used to have Fortified procaine penicillin injection towards my throat infections due to bacterial infections, it was working better, now it is not available anywhere in the market, will Fish Zole be helpful ?

  7. I’ve been reading penicillin is nearly worthless these days and is often prescribed so people think the doctor did something even if they really didn’t need it. How true that is I don’t know but it’s why I stocked Cephalexin as my main antibiotic.

    1. Not true. My Uncle is a Doctor, and said people will have to resort to fish antibiotics, because they have simply not been allowed to prescribe them. ZPack is now a 3 day, not 5. I buy all I can get, and close to exp date, I sell to people needing asap, and I restock. I have 500 plus bottles of different kinds in a freezer as I type. Study what each one is for, dosage, etc… before taking, and definitely make sure of your allergies! Fish Pen *Penicillin* is exactly the same as human antibiotics, and has helped me through some rough patches! I have taken several lose pills in to Walgreens, and asked what they were. Spot on every time! My pills have the same markings as the human ones do. (Thomas Labs ONLY!)
      And to the guy talking about Joplin, and Elvis— LMAO!!! They didn’t die from antibiotics! Good grief man! Educate yourself here! No one is talking about opiates here LOL! That’s what they died from! Benzos, alcohol, and pain pills NOT antibiotics!

      1. It is a little more to the point than saying, fish pen might give you (montazomas revenge).
        By the way, Joplin and elvis did self medicate. With the same type of drugs as people living in ghettos across this country.

      2. Any suggestions for pneumonia or chronic bronchitis if a person is allergic to the “cillin” family. Specifically a fish substitute for Doxycycline or the ZPak?
        Thanks in advance!

        1. I saw Doxycyline pills on ebay as fish antibiotics. I also saw Oxytetracycline HCL on the same page. I read that Doxycycline is a syntehtic antibiotic derived from Tetracycline.

          I’m not saying they are the same…but the info I was reading stated that Tetracycline treats many of the same things that Doxycycline does, including respiratory tract infections such as pneumonia.

      3. Janis Joplin died of a heroin overdose in a Los Angeles hotel in 1970, two weeks after the death of fellow rock star Jimi Hendrix.

      4. To the gentleman suggesting Elvis self medicated and should have only taken medications prescribed by a doctor, he did, in fact, only take what was prescribed.

        Research first if you want people to take you seriously.

      5. I need the proper antibiotics for an ear infection for my Wire Hair Fox Terrier. I know the dose for her weight Keflex, Cipro Amoxicillin, Penicillin? Keflex worked on Stephen King’s. “The Gunslinger” in the Dark Tower series. If I don’t hear from y’all, I guess if it worked for Roland, I’ll give it to George. In a bind.I’ve antibiotics and there were no side effects b
        & they worked as well as human RX

  8. Research some of the most common infections as-well-as some of the uncommon ones. Check to see if they are ‘aerobic’ or ‘anaerobic’ in nature. They each need their own type of antibiotic. If you treat an ‘aerobic’ bacteria with an antibiotic that is meant for an ‘anaerobic’ strain…it won’t work. If you stock up on a variety of antibiotics…make a list of the infections that each will treat. Make a list of all possible symptoms for each because in a SHTF situation the chances of having a lab to run the diagnostics…will probably be zero.

  9. I have used Fish Amoxicillin, Cephalexin and Sulfamethoxazole/Trimethoprim at different times for myself and my mother for UTIs, abscessed teeth and sinus or respiratory infections over the past couple years. They work fine. No problems. I have been purchasing extra for survival supplies also.

    1. Where do you purchase them?
      I am trying to figure out what to get and where to purchase them for when It hits the fan!
      Any help would be appreciated!

  10. My girlfriend does not have insurance. She had a root canal two years ago and it has never been right. Last week she got something caught in the tooth and it had been terribly infected.
    I found Fish Pen at Tractor Supply on Saturday, gave her an initial dose of 1000 mg and 500 mg every 6 hours since. I told her to remain on this dosage through Thursday.
    It’s only been 48 hours and she told me that this area and tooth in her mouth hasn’t felt this good in two years.
    We’ll make an appointment to get it fixed now, but this truly worked given the current situation.

  11. I have been using powdered Tetracycline an Doxycycline HCL for 15 yrs it is for Birds and livestock an old farmer taught me to use it and suggested covering the horrid taste in OJ or powdered tang when you can’t afford OJ or can’t keep it refrigerated in the case of an SHTF situation.
    I can’t actually tell you how much to take I just know from using it but you can figure it out by weight.
    It lasts a long time I keep it sealed in a Mason Jar to keep out moisture
    it used to be readily available at any feed store but now it seems to be gone.
    It is a Broad spectrum antibiotic. it will knock out e coli septicemia,tooth abscesses, and MRSA .
    in an emergency, this is a LIFESAVER and it seems they make it for fish as well.

  12. Have used Thomas Labs Fish Mox, Fish Pen, and Fish Flex as effectively as prescribed medication. Do your research. Know your body. I know what is usually prescribed for our sinus infections, my skin infections, and UTI’s. I stick to the kind of antiobiotics and dosages that our doctors have prescribed in the past for these conditions. I keep a log in the medicine cabinet, so I learn from the docs. We do not use them willynilly.

    1. Which one did you get for a uti I don’t have insurance and he gets very expensive to go to the doctor. And how much do you take for the Uti?

  13. I have fishmox. I got a prescription from the pharmacy and compared then same pill same color code and even the same number on the capsule
    My buddy worked for a vet years ago and he use to go to him to get antibiotics

  14. The Thomas Labs antibiotics are the same for humans. I have been taking them for years. Go to and input the letters/numbers on the pill into the screen. Push enter. It will pull up whatever pills you are looking for. They are real. It will show you a color of the exact pill. does not say anything about fish or aquatics on the site. The fish mox forte is the same for adults. No different.

  15. I pay over $700 month for health insurance through my work. My co-pay is $50 to see an urgent care doctor (it’s nearly impossible to get a same day or even same week appointment with my primary care doctor). It’s another $20 for a prescription co-pay. I know when I have a UTI. I don’t need to go through that whole thing. I’m well educated. I know about antibiotic resistance. I know when I need an antibiotic in order for something to not get more serious.
    I use Thomas fish flex for UTI’s/kidney infections. ($24 for 100 capsules)
    2 (250 mg) every 12 hours for 7 days.
    Take the entire course even if you are feeling better.
    Make sure to take probiotics along with that.
    It has always worked for my UTI’s.

  16. I just recently discovered fish antibiotics. I have lymphedema in my legs which means I get frequent cellulitis infections. My doctor refuses to give me a backup prescription for SMZ/TMP which is what I always take to get rid of the cellulitis. It’s also what works best for me when I have a UTI. Thanks to Thomas Labs, I was able to get a prescription of Fish Sulfa Forte and know that even if my doctor won’t prescribe, I’m able to get started early and catch the infection before it worsens. It’s a lifesaver in our country’s healthcare crisis. I agree that humans shouldn’t take this though until they thoroughly research what each antibiotic is used for. I also wouldn’t take a new antibiotic that I didn’t have previous experience with.

  17. I just received fish mox in the mail (thomas labs) and took 4 250mg. I have been battling a terrible sinus infection (neti pot doesnt work) for a week now. Right side of face very swollen, eye swelled shut, cant breathe out of right nostril. I dont have insurance, nor do I have extra money for scrips should I go to the emergency room. Ive heard about fish mox for years and now..really…its my only hope before going to the E.R. Im not allergic to penicillin so I am praying this works. I feel that there are too many thumbs up to this animal medication to not be true.

    1. I could not afford to pay for insurance and I get frequent uti’s so I started searching the internet for fish cephalexin. Cephalexin is what the doctor would prescribe and I was familiar with the dosage how long and how many times to take per day. So I began doing this and so far have had good results..

  18. Isn’t the idea here to stock a few bottles in your preps? Should SHTF or economic chaos that makes travel or paying for medical treatment be the reason to stock and NOT to routinely self medicate? And for the naysayers – are you that diligent in terms of the doctor prescribed treatments you receive? there is ample legitimate resources to educate yourself on what conditions are effectively handled by which antibiotics. Do your research and stock your preps accordingly.

  19. Military did research of effectiveness of antibiotics past expiration dates and said they are still good if stored properly as far as maybe 5 years after expiration date. The trick is not too much heat or light or moisture Dark, cool, dry is the way to store them.

    CHECK the drug names though; certain ones can be toxic after expiration and I can’t remember which ones it was.

  20. UTI Cephalexin 500 mg 4x a day for 7 days… (March 2020)- with Coronavirus going on I just called my pcp was transferred to the on call doc who called in my meds after I described my symptoms. I don’t believe a unrinalysis is necessary for an uncomplicated UTI- my last one was 12 years ago.

    My recent prescription by doctor for UTI was a significantly higher dose than another person above who took 2x 250 MG. My sister in law a pharmacist says Cephalexin is one of the safest antibiotics used in pregnancy etc… I really wanted to take less and she said not to because of antibiotic resistance happening… I have not used antibiotics for years- and hate to hurt my gut flora but she convinced me to take the larger full dose as prescribed.

    I recently stock piled on all of the ones from Thomas labs from for a “just in case” SHTF scenario.

    I will visually compare the fish Cephalexin with my prescription. Definitely would prefer a Doc one but don’t intend to use unless have to.

  21. Tried out some fish antibiotics to help with a possible STI; I was suffering from horrible symptoms that seemed to go unnoticed, but I had an inkling that it was probably from the guy I was seeing. I continuously went to the doctors for months, but there were no positive test results for any STI. After two months with all these alarming and unusual issues, my heart rate started to slow down. So after extrenuous amounts of research on forums and medical studies, I decided to just take the plunge and buy fish antibiotics. Not sure if any of it cures gonorrhea, chlamydia, or syphilis, but it definitely cleared up a lot of my symptoms and got me feeling better after 3 days.

    I’m still trying to go to the doctors to try and get a proper diagnosis of anything, as it seems that I am hanging onto my health by a string.
    I know these antibiotics are a last result and I am not trying to overuse them to gain in case of any resistance towards this last resort solution.

  22. I have used Thomas labs about 5 times for swelling infections on my gums ans teeth .Trust me it saved me .The infection could kill me so why not take amoxicillin for it .Thomas labs isnt some bullshit Mexican mail order pharmacy they are legit 100% when u pop the bottle u can smell amoxicillin and when u look up the pill id it says amoxicillin not fish pills its safe for humans .

  23. My mom was pharmacist . When I was 12, the doctor prescribed tetracycline for acne in the 1970’s.
    My dog also had a previous prescription for that, and my mom said take those pills first.
    I said Mom, those pills are for dogs only, and she said, it’s the same dam thing only packaged differently.
    Also, I learned from people that worked at the local family feed store in semi- rural towns that they will sell you antibiotics over the counter for ” your pet , but really you”.
    Just do your homework online to see what is normally prescribed for your condition, and then ask for it, or order it online.

    1. It’s my understanding that Thomas Labs is discontinuing making antibiotics. I am still trying to find another brand I trust

  24. Maybe I am the only prescriber/physician posting here but physicians are not prone to offering prescription for antibiotics unless they feel the problem is bacterial and will be properly treated with the antibiotics where the benefits outweighs the risks. There are serious problems with overprescribing antibiotics such as bacterial development of resistances ( seen more in other countries with looser prescribing practices) and very serious problems such as medication interactions, allergic reactions, and injuries. C diff colitis can be a terrible problem which develops when the normal colonic bacteria are destroyed by antibiotics and allow Clostridium difficile bacteria to become prominent. The Clostridium difficile bacteria produce a damaging toxin that can terribly damage the colon. The C diff colitis can be very difficult to treat and sometimes (infrequently) requires surgical removal of colon- I have seen this. Then there are problems with yeast infections that frequently occur with the destruction of normal body bacteria ( the normal body bacteria are harmless and would have competed with the yeast but the harmless body bacteria were destroyed by the antibiotic). There is risks of medication interactions (like antibiotics and some blood thinners), injury ( like tendon injury with Cipro or teeth staining with tetracycline, kidney or liver damage), and interference with other medications such as failure of birth control meds with certain antibiotics. Proper dosing is sometime dependent on other medications being taken or underlying issues such as liver or kidney disease. Your prescriber is responsible for those concerns- are you? So to summarize – antibiotics can cause problems due to resistances, inappropriate dosing, allergic reactions, medication interactions, medication injuries, yeast infections, C diff colitis and others. I understand need to stockpile antibiotics if the SHTF – they can be life saving. I also empathize with needing to save money. In less dire circumstances you are better served with proper medical guidance.


  26. Thomas Labs has discontinued their line of antibiotics. Anyone out there have a trusted brand they could recommend? Thanks.

  27. All these people in the comments with recurring UTI’s. All you have to do is drink cranberry juice. Or try the cranberry pills!

    I hate cranberries and the juice, but mix it with whatever else I am drinking.

    I have never had a UTI! NEVER.

    Still trying to find a safe and reliable option to Thomas Lab Fish Mox, since Thomas Labs is no longer Making it!

    I give to feral and my cats when needed.

    What is a safe alternative to give to cats?

    1. Fish Aid! Never-mind Discontinued too!
      ( I must have bought Fish Aid, when I could not get Thomas Lab, a few years ago)

      Only other one I can find is Aqua-Mox.

      But, cannot see the whole bottle to see all ingredients.

      active ingredient says – Amoxicillin .

      I still have some Thomas Lab Fish Mox, and a full bottle of Fish Aid left. And both just expired a few months ago.

      If anyone gets Aqua-Mox. Please let us know if the only ingredient is Amoxicillin! I will need back up for my cats!
