Is your dog a test subject for makers of Proheart 6?

I received an e-mail recently regarding the subject matter. - the e-mail is purportedly from a veterinarian. This is for your information - just in case you would ever even consider giving this drug to your beloved companion animal! - Jean Townsend


I recently attended a veterinary continuing education seminar at which the lunch (captive/paid for by manufacturer) presentation was on Proheart 6. The company rep told the gathering of veterinarians the following regarding the recent reintroduction of the product to the market after its earlier suspension:

Regarding the new administration guidelines for not giving Proheart 6 within one month of vaccinations and performing very minimal blood work prior to giving injection: "this is not about safety; it is about building a pristine data base for the FDA (that they can use to further evaluate safety/side effects of the product)."

Bloodwork should be performed but you do not need test results in hand prior to giving the Proheart 6 injection because "it does not have to do with safety for the animal but with data building."

Regarding age limitations of only administering to dogs over 6 months to under 7 years: these are only for the 1st injection of Proheart 6; if the dog has no adverse effects from 1st injection you can then give outside of these age limits.

Proheart 6 removes issues of Pet Med Express taking away veterinarians’ income for heartworm preventatives. It bypasses issues of owner noncompliance with giving pills as directed. It addresses our sour economy, and puts you in the driver’s seat.

When the question was raised if a dog is presented for needed vaccinations and Proheart 6 injection at the same time, 'what should the veterinarian do?', the reply was: "in order to develop the greatest degree of confidence in the data, hold off on giving vaccine(s), give the Proheart 6 injection and have owners come back one or more months later for the vaccine(s)".

It was repeatedly pointed out that Proheart 6, "still allowed in other countries and the #1 heartworm preventative in some of them, is the same product produced in the same place in the US."

"It’s all about confidence," the manufacturer's rep said, "clients will do what we tell them to do."

The deadliness of heartworms was stressed, which is true. But NOT ONE WORD was ever mentioned regarding death as a potential side effect, and when one veterinarian unfamiliar with issues surrounding the product asked what type of side effects had been seen, the response was "some inappetance, vomiting/diarrhea, elevated liver enzymes, that type of thing."

If anyone fails to see in the above the fact that a product that has killed dogs, has been reintroduced to the national market at the potential expense of the lives of BELOVED FAMILY CANINE COMPANIONS not for their own safety but in order to "build a data base," well….that’s exactly what has been done.
