I am wondering if there is any books or publications that would be useful in the subject of using veterinary medical supplies and medications in humans in an emergency situation. Medicines would include anti-fungals, antibiotics etc and supplies would include syringes, staples and suture kits. Any info appreciated.

A person trained in medical care will know what they are. There are various medciations that are used in animals that are actually used for humans ( and a lot more that are not) and of course in an emergancy situation, I have seen regular needles and fishing line used to sew up wounds. ** out in the wilderness.

I hope you are not trying to do surgery or something like that :(
I know that animals take amoxocillin as humans do but I don't know what the difference in it might be, maybe the dosage?
I would be super careful of something like this and check each thing out thouroughly.
I have a feeling IF it is interchangeable between animals and humans it would be more toward the animals using the human medicines. But possibly it can be the other way around like with hylaronic acid.

So, Fr Chuck, are you saying I should get a general background in regular medicine and then apply that knowledge to use with veterinary medical supplies? So maybe a set of textbooks used for a college nursing course? Or a book on pharmaceuticals? Or is there one good book that would say it all?

And no, don't worry, I'm not asking because I want to save a buck on surgery or something! I am a preparedness-minded person and I have already learned a lot in other areas such as growing foods, raising animals for meat, canning, preparing my home for power outages... basically everything I would need to be able to do to survive in emergency situations where regular services like gas, electric and grocery stores are not available. I know First Aid very well, but would like to get more in depth on medical emergency situations, and if Dr's and hospitals are unavailable I'd like to be able to perform in the situation for myself and others. From having animals, I know that antibiotics and other medicines are available for purchase through a veterinary supply catalog without any kind of prescription.

Merck Veterinary Manual has a detailed section on pharmacology. If you have the will to learn it, you can learn enough easily. I know many people who have used veterinary meds for decades following the weight guidelines and symptomology guides. It is really a shame that people have to resort to this. I have even known of licensed vets using the meds for decades... not abusing... but USING the medicine for their intended use.

Merck Veterinary Manual has a pharmacology section that is easy to use and learn from if one wants to apply themselves. I know of many people using vet meds for decades with no harmful side effects. Most of the vets that I know ONLY use the vet meds. They use the meds for their intended purpose, NOT abusing the drugs or their privileges. And I think that to say the drugs are not the same or less than are part of a phallacy system. No drug company is going to risk a lawsuit because a million dollar Walking Horse or race horse is injured.
