Are Fish Antibiotics Safe for Humans?

Yes, they are! Standard human antibiotics inhibit the growth of microorganisms and destroy them. Fish antibiotics do the same thing.

The only difference is that one was synthesized for humans and the other was made to treat fish. So, the packaging may look different.

Nevertheless, both contain the same active ingredients as human meds. Plus, they’re available in the same doses and types.

More importantly, you don’t need a prescription for these fish meds. Now here’s the best part: they’re not as expensive as prescription meds!

For survivalists, they’re the ultimate go-to option. It’s also why many pack Fish Mox and Fish Pen for human use along with their survivalist gear.

Prepping and Storing Survival Antibiotics


Now you can see why many survivalists consider them an essential part of their stockpile. Here are a few basic tips for storing and prepping antibiotics.


Take Your Pick

There are two basic forms of antibiotics: capsules and suspension. The former has a longer shelf life. It’s also easier on the taste buds.

Alternatively, the latter is faster-acting. It gets absorbed into the bloodstream within several minutes. To put it into perspective, capsules take about half an hour before it’s completely absorbed.

That’s for humans. Fish are a different story. You just drop the meds in the tank water and the fish absorbs it through their skin.



Antibiotics that come in capsule or tablet form are easy to prep. The main thing you have to remember is the dosage. Check the label to make sure you’re taking the right amount to treat your bacterial infection.



Some antibiotics come in powder form, not pills. They’re referred to as ‘suspension antibiotics.’

These types usually come with a packet of distilled water to be added to the powder in the bottle. Next, make sure the cap is firmly closed. Then, shake it vigorously to dissolve the powder.

Bear in mind that once antibiotics have been dissolved, they should be stored in the fridge. This way, you have a better chance of slowing down its chemical breakdown.

Check the Expiration Date

When prepping antibiotics, it’s important to know their expiration dates. Most will last anywhere between two to three years, depending on the manufacturer.

Suspensions are known to have a much shorter shelf life. Once the powder is dissolved, it should be used within the first 14 days.

It’s worth mentioning that stability studies were carried out on different types of meds. They found that many of them were still effective up to a year longer than indicated on the package.

That said, medical experts caution against using expired medications. Even if it’s within a year, it’s always better to stick to the dates written on the bottle.

Picking the ideal storage containers boosts the med’s shelf life. Look for airtight, moisture-resistant containers. They’re great at preventing an infestation of mildew and mold growth.

Another smart choice is durable, hard-sided containers or Altoid tins. These will protect your meds against drops or bumps.


Store Bottles in a Cool, Dry Place

Experts recommend you store antibiotic pills somewhere cool and dry. The bedroom or basement work better than the bathroom. The reason? These rooms provide the perfect conditions to enhance shelf life and keep the meds stable for longer.

The bathroom, however, is full of moisture. The light is also much brighter and more direct in the bathroom than in the bedroom.

Both moisture and light can affect their composition. This leads to a breakdown of the chemicals, which reduces the med’s shelf life.


Possible Risks of Prepping Survival Antibiotics


Despite all their advantages, they do come with a few drawbacks. Check them out below.


Not FDA Approved

Fish antibiotics aren’t approved by the Food and Drug Administration (FDA). They can’t confirm whether they’re safe or not for human consumption.

The FDA hasn’t run any tests on these meds. So, there’s no way for them to know whether they contain the same ingredients indicated on the label.


Allergic Reactions

Since antibiotics are made up of chemicals, they may trigger certain allergic reactions. The same goes for fish medications. The most common types of allergies are usually caused by penicillin or amoxicillin.

Before taking any type of medication, speak with your doctor to make sure you’re not allergic. They’ll tell you which is safe to use.

Your doctor will also recommend a suitable type of antibiotic for you. Each type of antibiotic is designed to treat a certain type of infection. So, it’s important to know which is ideal for your condition.


Antibiotic Resistance

Antibiotics are made up of various chemical compositions. They share one common factor: they treat only bacterial infections. None of them treat viral infections.

Let’s say you’re sick with one type of bacteria, but you take an antibiotic designed for another type. It could lead to antibiotic resistance. This is where the microbe is no longer affected by the treatment and becomes immune to it.
