How to get antibiotics for prepping? ( Top 18 Sources )

For decades antibiotics have been used to save countless lives, especially during global SHTF events like WW2. Conditions on the battlefield were harsh and bacterial infections were common, even a simple scratch could end up being deadly. One of the first antibiotics, the Penicillin was discovered by accident in 1928 by Alexander Fleming, and to this day it is still one of the most popular antibiotics.

Most preppers tend to use fish antibiotics for prepping, these are generally considered safe although they are not meant for human consumption. On the other hand, some preppers stockpile natural antibiotics like honey, which is definitely better than fish antibiotics. Just keep in mind that there is a good reason why you need a prescription, as it can be extremely dangerous to take antibiotics without the advice of a doctor.

No matter if you are a prepper or not, having antibiotics in an SHTF event is vital. There are several natural antibiotics but my suggestion is to go with one that in addition to its antibacterial property it also has anti-inflammatory and antioxidant properties Click here to check it out on

Antibiotics are very powerful, taking them without having consulted your Dr is dangerous, and this is why you can not buy antibiotics without a prescription. Not being able to buy antibiotics without a prescription is making it harder for preppers or anybody else to have these antibiotics for use in the future. The reason why you need a prescription is that there are several kinds of antibiotics, and not using the correct one could end up worsening your situation. Antibiotics are also extremely useful for people living off the grid often isolated from other people if you need more information about off-grid living, check out my article Off grid living legal states ( Top 22 ).

During an SHTF situation, a medical kit is vital, usually, these have you covered, but what if a cut or bruise gets infected. In this case, you will need antibiotics, and as it is an SHTF situation you can not simply go to the local drug store and buy them. While making their bug out bags most preppers do include antibiotics from different sources like fish antibiotics, foreign antibiotics, or antibiotics used for animals.

As preppers, we have to think outside the box if we want to have antibiotics in our bug out bag. Currently, there are several sources where you can get antibiotics without the need for a prescription, usually, these antibiotics are made for animals like dogs, cats, fish, and so on. These are not recommended for human consumption and not approved by the FDA but this doesn’t mean that they are not a viable source of antibiotics in an SHTF situation as the function of any antibiotic is the same no matter if it is used by a human or animal. If you are wondering which states are the best for preppers then check out my recent article Best states for preppers ( Top 15 ).

Get fish antibiotics for prepping

Fish, as do all animals, get the occasional bacterial infection, these are also treated with antibiotics but in a much smaller dose. Usually, the same companies which produce antibiotics for humans also produce antibiotics for animals and in most cases, these have the same USP (United States Pharmacopeial) grade. You can easily buy and stockpile fish antibiotics from any local aquarium store or online store. Fish antibiotics for humans is not a new idea, in fact, there are a lot of people doing it for decades. When you search around the web you will notice that a lot of websites will recommend SHTF fish antibiotics.

Get online antibiotics for prepping

As with everything online you need to find a reputable source to buy from. There are several antibiotics that you can buy without the need of a prescription in different countries, the problem is that importing these antibiotics is illegal but authorities rarely bother with it. There are different laws in almost every country in regards to antibiotics, while in the US you can not legally buy antibiotics without a Dr’s consultation and a prescription but there are many countries that allow it.

One of the biggest dangers of buying antibiotics online is that you never know if it is an actual antibiotic or a fake antibiotic, there is a massive industry in selling fake medicine online so beware of that.

It is vital that you identify what kind of infection you have and what kind of antibiotics you need to treat them. There are two types of antibiotics bacteriostatic and bactericidal, the first one stops the bacteria from reproducing while the second one actively kills off the bacteria.

Cephalexin for prepping

Cephalexin or Keflex is one of the more powerful antibiotics which you can buy. Usually, it is used to treat infections from the Staphylococcus aureus bacteria, and infections from other bacteria in the upper respiratory system, ears, skin, and urinary tract. As Cephalexin is one of the stronger antibiotics it will produce some side effects.

Ciprofloxacin for prepping

Ciprofloxacin or Cipro is more of a general-purpose antibiotic as it is often used to treat, prostate infections, bone infections, pneumonia, and bronchitis. This antibiotic is often used to treat anthrax and even typhoid fever.

Clarithromycin for prepping

Clarithromycin is used to treat various bacterial infections like line respiratory tract infections, skin infections, and so on. Generally speaking, this is a plan B antibiotic, if the infection isn’t responding to other antibiotics then Clarithromycin will be used.

Metronidazole for prepping

Metronidazole or Flagyl is usually used to treat parasitic infections such as amebic liver abscesses, amebic dysentery, and Giardia. In addition to this sometimes it is also used to treat common infections to the stomach, vagina, liver, and even for brain infections.

Amoxicillin for prepping

Augmenting for prepping

Augmenting is one of the most powerful antibiotics, and people oftentimes have a couple of side effects like stomach pains. Augmenting is used as a general antibiotic in most cases as it can treat most bacterial infections.

Bacteriostatic antibiotics for prepping

Bacteriostatic antibiotic slows down or even stop the ability for the bacteria to reproduce by attacking the bacterias DNA, metabolism and protein production. Each of these is vital for bacteria to reproduce, destroy one of these functions and the bacteria can no longer reproduce. After which your immune system can destroy them as there is no threat of being overrun by the bacteria.

Bactericidal antibiotics for prepping

Bactericidal antibiotics kill the bacteria, usually, these antibiotics interfere with the bacteria’s ability to create a cell wall, without the cell well the bacteria dies. The most common bactericidal antibiotics are Penicillins like Penicillin V, Amoxicillin and Flucloxacillin.

Use of Penicillins

  • Penicillin V is used for throat infections
  • Amoxicillin is used for chest infections
  • Flucloxacillin is used for skin infections

Antibiotics can be of a broad spectrum which means that these antibiotics attack different kinds of bacteria, including the good ones, which are mostly found in the gut. The second type of antibiotics are of a narrow spectrum that attacks only 1-2 kinds of bacteria, usually, these are the best kinds of antibiotics although if you are not a Dr it could be extremely hard for you to identify what kind of bacteria is causing the infection.

Do antibiotics kill viruses?

Most people think that antibiotics are also effective if you are infected with a virus, but antibiotics do NOT kill viruses as these have a completely different structure to bacterias and the sole purpose of antibiotics is to kill or stop the spreading of the bacteria and no other germ or virus. Viruses do not have a cell wall, and they incorporate themselves into the host’s cell in order to multiply. Antibiotics meant to kill bacteria by destroying the cell wall will not work as these do not have cell walls, and antibiotics that stop the reproduction of bacteria also won’t work as antibiotics will not attack human cells in which the virus is hiding.

Viruses usually go away after some time provided that you have no other health issues, although these still weaken your immune system, and in an SHTF situation getting an infection plus a virus will not be uncommon. In addition to your personal use for the antibiotics, this will be a very valuable item to trade with, although these come with a limited shelf life during an SHTF people are going to get whatever they can. Antibiotics will be in short supply in case of a WW 3, for more information check out my recent article What would happen if World War 3 started? ( Top 8 Predictions ).

What is resistance to antibiotics?

This is an ever-growing problem in our world, believe it or not, but most processed foods have different kinds of antibiotics. Like in the case of milk, cows are fed special food to make them produce unnatural quantities of milk, during the process the cow’s immune system gets weaker and it is harder for their immune system to work. In this case, bacterial infections for cows are common and to combat these veterinarians administer them antibiotics, which inevitably end up in the milk and in our bodies.

You do not even have to be an avid milk drinker to ingest these antibiotics, as there is a lot of processed food that contains milk. After years of being exposed almost every day to these antibiotics, bacteria are starting to adapt and there are more and more cases around the world where treating an infection with antibiotics is not feasible as the bacteria are resistant to it.

Antibiotics to stockpile for prepping

If you have an opportunity to buy some of these antibiotics with or without a prescription you should add them to your prepping stockpile. Below is the list of the most popular antibiotics on the market today. The below antibiotics will be able to treat anything from a urinary infection to more serious infections, altho you still need ample knowledge on which type of antibiotic is best for each bacterial infection.

  • Clarithromycin
  • Zithromax
  • Amoxicillin
  • Ampicillin
  • Ciprofloxacin
  • Doxycycline
  • Cephalexin
  • Metronidazole
  • Erythromycin
  • Tobramycin
  • Trimethoprim

In Conclusion

There is a reason why you can not buy antibiotics without a prescription as it is very dangerous and possibly life-threatening to administer the wrong kind of antibiotic or to misdiagnose a viral infection with a bacterial infection. There are a lot of preppers using fish antibiotics, although you might find that the FDA has started to regulate these and you can no longer find them in pet stores. I am not a big fan of antibiotics meant for animals, instead, I try to stockpile as much as I can with natural antibiotics.
