Welcome to the forum, alexia642!

Quite frankly, I take from this that some of "your" clinic's standards of care are determined by the least caring/educated customers who come through the door...and that just leaves me shaking my head in disbelief.

You've cloaked yourself very generally as "we in the veterinary field".....are you a Veterinarian/Technician/other?

While you may not have received reports from your clients of serious side effects associated with Convenia, my understanding is that such reports/discussions exist - some on VIN - and I am aware of others in open discussion boards/forums. I give you one example http://www.felinediabetes.com/phorum....php?8,1964921

Without the benefit of any veterinary education, even I can recognize from the generally available literature that this is NOT a drug to be given willy-nilly (as appears to be the general practice now) (and quite obviously peddled as such by the manufacturer - read the name of it again!)...the "official" info from the maker listed on drugs.com states "Warnings: To limit the development of antimicrobial resistance, the extra-label drug use of cefovecin is not recommended http://www.drugs.com/vet/convenia-in...phile-can.html From the UK's National Office of Animal Health: "It is prudent to reserve third generation cephalosporins for the treatment of clinical conditions, which have responded poorly, or are expected to respond poorly, to other classes of antimicrobials or first generation cephalosporins. Use of the product should be based on susceptibility testing..." http://www.noahcompendium.co.uk/Pfiz...ts/-43050.html

Finally, inconveniently burried in the manufacturer's data sheet is this

FOREIGN MARKET EXPERIENCE: The following adverse events were reported voluntarily during post-approval use of the product in dogs and cats in foreign markets:
death, tremors/ataxia, seizures, anaphylaxis, acute pulmonary edema, facial edema, injection site reactions (alopecia, scabs, necrosis, and erythema), hemolytic anemia, salivation, pruritus, lethargy, vomiting, diarrhea, and inappetance. http://www.pfizerah.com/PAHimages/co...ill_041108.pdf
Only in "foreign markets", huh? Not bloody likely!
