I don't know any American pet shops but I looked at Amazon.com and it seems to (normally) be sold without a vet's prescription.
I tried to find a listing of ingredients on this item to see if it contained chloroquine phosphate. I did find one article that claimed it was composed of two solutions: Formalin (Part A) and Methylene Blue (Part B).
Formalin: A 37% aqueous (water) solution of formaldehyde, a pungent gas, with the chemical formula HCHO, used as an antiseptic, disinfectant, and especially today as a fixative for histology (the study of tissues under the microscope).
Methylene blue, also known as methylthioninium chloride, is a medication and dye. As a medication, it is mainly used to treat methemoglobinemia. Specifically, it is used to treat methemoglobin levels that are greater than 30% or in which there are symptoms despite oxygen therapy.
Methylene blue was introduced as an antimalarial medication in 1891. It was the very first synthetic, rather than natural, compound ever used in clinical therapy. As an antimalarial, methylene blue has been replaced by its derivatives, mepacrine and chloroquine.
So if I am interpreting this correctly, this product does not contain chloroquine. But it does contain formaldehyde. I wonder how many people would be willing to drink a teaspoon of formaldehyde?

But that brings up another very interesting point.
Preppers are very resourceful and innovative. Many feel that in a great cataclysm they will need medicine such as antibiotics. Now since most medical doctors do not write prescriptions for drugs for an end of the world situation, preppers have discovered that almost the same drugs are available as fish/animal medication. And obtaining drugs through this approach is easier.
So if you want access to a drug such as chloroquine, one might obtain such medicine on-line without having to go through a doctor.
So the basic question, THAT ALL THE REPORTERS, failed to report is EXACTLY what did she take? If she took a fish tank cleaner like the one above, she did not take chloroquine, the reporters failed the public and rightly should be labeled as FAKE NEWS. [perhaps she read an article that said chloroquine could be obtained as fish tank cleaner and assumed any fish tank cleaner contained chloroquine.
Or did she buy a very special fish medication called chloroquine phosphate, store it on a shelf for years and self medicate with it. Most preppers don't want to die. They would be very meticulous about taking the right dosage.
