Fish Antibiotics For Humans

In the UK, antibiotics are a prescribed medicine, meaning you they can only be obtained once you have seen your doctor and have been given a prescription to buy at the pharmacist.

Now that's all well and good at the moment, when things are fine, and people are just busily struggling along day to day, getting on with things.  But how well prepared are you if things go bad, and the doctors aren't there to prescribe, or the chemist has been ransacked, and all you have is empty shelves..?

An Infected Cut Or Chesty Cough
 Now Has The Potential To Kill You

In a disaster or bug out situation where the normal medical facilities such as doctors, pharmacies, and hospitals are not able to function, essential supplies of basic medicines will simply not be available. 

As well as that, your pharmacist will not hand out anti-biotics without you first visiting your doctor for a prescription. Do you know why? To ensure your illness is in fact a bacterial infection, as viruses do not respond to antibiotics.

For example Influenza is a virus infection – this is why your doctor will never prescribe you antibiotics for this.

In this article, I will take a look at the options available. Their safety and feasibility of this option for us preppers, as well as considering other important survival and safety factors.

As preppers we know that an awful lot of things taken for granted now, will become very scarce and hard to get hold of.

In times of hardship and when you’re in a pinch, many everyday items can be replaced by alternatives:
The same applies to many traditional medical supplies:
Honey makes excellent  cough syrup, spirits like vodka can be substituted for rubbing alcohol, even your T-shirt and a safety pin for a sling.

But there are a few, essential, must-have, lifesaving items that nothing can replace. One such items is: oral antibiotics.

Are Fish Antibiotics
Safe For Human Consumption?

Before going any further in this article, deciding to take a drug that is technically not for human consumption, requires a degree of research.
That's where you come in: Do Not Take My Word For It. Do you own, in depth research first. There's a lot of information on the internet, giving fish antibiotics both a good and bad name.
I'm not a doctor, chemist, or any other medical boffin. So to some degree, my opinion is useless!  But I have looked at as much information as I can to make a calculated decision and here are my conclusions:

There are three main questions to the safety of fish antibiotics for humans:

  1. What are the specific ingredients comparing Fish Antibiotics vs Human Antibiotics?
  2. Do dosages differ? If so, what is offered?
  3. Are there any side effects?

The list below gives the fish antibiotic name, active ingredients, dosage and what symptoms they cure.

Fish Antibiotic 

Fin Mox Forte

Active Ingredient




Amoxicillin is a penicillin antibiotic that fights bacteria. Amoxicillin is used to treat many different types of infection caused by bacteria, such as tonsillitis, bronchitispneumonia, gonorrhoea, and infections of the ear, nose, throat, skin, or urinary tract.

Fish Antibiotic 

Fin Flex Forte

Active Ingredient




Cephalexin is a cephalosporin (SEF a low spor in) antibiotic. It works by fighting bacteria in your body. Cephalexin is used to treat infections caused by bacteria, including upper respiratory infections, ear infections, skin infections, and urinary tract infections.

Fish Antibiotic 

Fin Flox Forte

Active Ingredient




Ciprofloxacin is an antibiotic used to treat a number of bacterial infections​. This includes bone and joint infections, intra abdominal infections, certain type of infectious diarrhearespiratory tract infections, skin infections, typhoid fever, and urinary tract infections, among others

Fish Antibiotic 

Fin Pen Forte

Active Ingredient




Penicillin (PCN or pen) is a group of antibiotics which include penicillin G(intravenous use), penicillin V (use by mouth), procaine penicillin, and benzathine penicillin (intramuscular use). Penicillin antibiotics were among the first medications to be effective against many bacterial infections caused by staphylococci and streptococci.

*side note:
Penicillin was among the first natural oral antibiotic that could be used for medicinal
purposes, and discovered in the 1950s.

However, two other drugs, Ampicillin and Amoxicillin are within the Penicillin family, so if you are allergic to either of those medicines, you will also be allergic to Penicillin.

As preppers having these other sources of antibiotics could make things a little easier should the SHTF. The fish antibiotics appear to have the same ingredient, and in many cases, also have the same dosage as those drugs offered to us from the doctors/pharmacies.

That being said, side effects, if any, are the same as for human antibiotics.

General Safety Factors To Consider
When choosing
 Fish Antibiotics For For Humans

Dosage Of Fish Antibiotics For Humans

  • Correct dosage is important, so mimic the amounts that would be recommended by your doctor if possible. To double check dosages, there is a very good international website for reference here:  

Contents Of Fish Antibiotics For Humans

  • The fish antibiotic should contain only one major ingredient: You do not want a mixture of other ingredients like a fish health supplement for example - or any other ingredient that is not for human consumption. Ensure the the fish antibiotic only contains the main ingredient you require. 
  • Amoxicillin
  • Cephalexin
  • Ciprofloxacin
  • Penicillin

Storage Of Fish Antibiotics For Humans

  • As with all medicines, fish antibiotics need to be stored properly: A cool, dark cupboard, away from children is ideal. The seal should be intact, and the bottle unopened until required. Take note of the expiration dates and renew as and when possible.

Will Fish Antibiotics
Work The Same As Human Antibiotics?

From my research, and also from hours of trolling forums looking at individual cases, it would seem that fish antibiotics are ok for human use.
There are a huge amount of people already taking them, especially in countries where the cost is exorbitant. From what I have found, side effects are pretty much zero, yet results on par with human antibiotics.
But again, I reiterate, do your own research and form your own opinion. Do not take my word for it.

Who Sells Fish Antibiotics?

Obviously a fish pet shop should would sell these, along with other animal medicines. 
But there are plenty of other places to look online.

The key thing to remember is the type of antibiotic, the dosage and, most importantly, ensure it only contains the prescribed drug. i.e: Penicillin only, like the one shown here, and does not have any other fillers or ingredients added.

Are Fish Antibiotics Safe For Humans?

I would say, based on the evidence I have researched and found, that fish antibiotics for humans are a very low risk, and definitely have their place in a preppers store and bugout bag.

The type and grade of ingredient is identical to that of the 'human grade' equivalent, essentially making them the same product, under a different label, and seeing as there is no discernible difference, I would say in a SHTF situation, where you have no access to a doctor or antibiotics, these make a perfect prepper alternative.

So now for the third and final time: this is my opinion only, based on extensive research - your job now is to do your own research and make your own informed decision.
Having said that, I hope this article has helped you.

    Steve this is really good information. I’m a 54 yr old mum from Northern Ireland and my hubby and daughters think I’m nuts!! But I really do think something is going g to happen and we need to be prepared. I’m just starting out and I think I would dig in. I live in a fishing village on the east coast of the north it’s called ” the cards penninsula” could you tell me if you think that’s the right thing to do?
