Can Humans Take Fish Antibiotics? (4 Facts You Should Know)

can humans take fish antibiotics

It’s impossible to know when the world will be faced with a SHTF situation, and because of this, part of being a prepper is ensuring that you’re stockpiled up on as many different supplies and items as you can be. There are the common things like food, water, toilet paper, etc., but what if you get sick or need to relieve pain? Antibiotics are essential for this, but stockpiling on these is tricky. As such, we often hear people ask “can humans take fish antibiotics?”.

This might seem like an out of the blue question at first, but once you start to really think about it, you could see why some would ponder this. Fish antibiotics can be purchased easily online or in-stores, making it very easy to get your hands on them.

Want antibiotics that are made for humans? The only legal way to do this is via a prescription from your doctor. As such, storing up on them is very difficult.

Some preppers claim that fish antibiotics are perfectly healthy to take, whereas others are still on the fence about whether this is safe or not.

Let’s shed some light on this matter.

The argument for taking fish antibiotics

As mentioned above, the biggest advantage of getting fish antibiotics is that they’re so easy to come across. Take a quick look through Amazon, and you’ll see tons of different options to choose from that you can purchase without any sort of prescription. Just add the antibiotic to your cart, pay for it with your card, and it’ll be at your doorstep within a few days.

Most antibiotics cost around $20 to $50, and when compared to a doctor’s visit that requires a prescription and a few hundred dollars, it makes sense as to why people would choose to go this route when trying to figure out how to get antibiotics for prepping.

So, the ease of use is certainly there, but what about the safety side of things? These are fish antibiotics, and as such, weren’t designed for human use.

We’ll get into what some have to say against this in a bit, but there’s a decent argument to be made for why some firmly believe in taking the stuff.

For starters, fish antibiotics are quite similar to what’s prescribed to humans. When buying fish antibiotics, buy ones that include only one ingredient, such as amoxicillin, penicillin, ampicillin, etc.

There are some fish antibiotics that contain other ingredients for fish health supplements, and these are the ones you’ll absolutely want to avoid.

Once you find an antibiotic that has the single ingredient you’re looking for, research the dosage to see how much you should take. Fish and human dosages are different, so you’ll want to be careful about truly taking the right amount that your body will be able to handle. Sites like should be able to help with fish antibiotics for humans dosage amounts, and along with this, you should also consult other preppers, and perhaps even a doctor.

Furthermore, it’s important to keep an eye out for potential allergic reactions. A small amount of people are allergic to penicillin, so if you have this, try to find an antibiotic that uses something else for dealing with the pain.

The argument against taking fish antibiotics

So far, it might seem as if taking fish antibiotics makes a lot of sense. It does to some preppers, but we also need to talk about the negatives associated with it.

First and foremost, while fish antibiotics should be covered by the Food and Drug Administration, they aren’t. Antibiotics for cats and dogs are, but there’s no such provisions for antibiotics made for our aquatic friends.

The FDA recently reached out to and said the following:

“If consumers are seeing these products in stores, they should be aware that these products have no assurance of purity, safety, or effectiveness. The FDA does not have any information about the unapproved antibiotics sold in pet stores because they have not be evaluated for quality, safety, effectiveness, or purity. We strongly advise people to not substitute them for approved products that are intend for use in humans as prescribed by their health care provider.”

The FDA is reportedly looking into changing this, but the fact of the matter is that it doesn’t see much need to. Fish antibiotics aren’t really a concern for the organization seeing as how small of a market segment they are, and we wouldn’t hold our breath for this to change anytime soon.

It’s certainly possible to order a fish antibiotic, get a bottle that’s perfectly good to use, is pure, effective, and doesn’t have any fish supplements, but there’s also the chance of getting something that’s going to cause major problems.

You’re playing a gambling game when substituting fish antibiotics for human ones, and any doctor will tell you that any benefit you get from this isn’t worth it when you consider the potential risk involved.

All antibiotics kill good and bad bacteria alike, and because of this, doctor’s prescribe antibiotics with careful planning in mind – how much to give you, how often you should take them for, at what times during the day etc.

When you take these matters into your own hands and decide to start killing off bacteria willy nilly, you’re setting yourself up for potentially huge medical complications.

You might get lucky, or you might not. That’s the game you play when taking fish antibiotics, and it’s a game that can be quite serious.

Final Thoughts

So, can humans take fish antibiotics? While they can with the chance of having nothing go wrong, there’s no guarantee that everything will be hunky dory. Being your own doctor and prescribing antibiotics to yourself can be dangerous, and while some of you may be willing to take that risk, others may not. It’s your life and your decision to make, but should you choose to take that risk, just make sure you know everything involved with it.
