We all know that antibiotics
kill both good and bad bacteria. This is why when
taking antibiotics most folks take probiotics
with good bacteria or eat lots of yogurt to prevent an
imbalance in their bodies (this is why we get stomach
discomfort if we don't take care of our good

Author of this Page Believes about Convenia
I am not a
medical professional. I am a highly educated consumer
and experienced pet owner. As a strong believer in
body balance of good and bad bacteria - I believe that
Pfizer has not perfected its research for Convenia and
how it reacts with good and bad bacteria in cats and
dogs. (Hence, the many mishaps happening to
peoples pets). I feel that the drug works too
well and it rapidly kills off the good bacteria too
quickly for the animals' body to keep up, creating
shock, thus causing organ failures or other serious
reactions, including but not limited to anemia,
seizures, etc. (Please read the documentations and
message board on Facebook for more consumer stories).
My personal stories in brief:
In early 2012, a late night emergency
veterinarian administered convenia to my 17 year old
cat (Misses) for a urinary tract infection without lab
culture. Within 2 hours my cat began to have
seizures. I immediately administered probiotics,
understanding the mechanism of the antibiotics and how
they kill both good and bad bacteria. Could not see
any other reason why my cat would react to bacteria
being killed off in her body, unless too much is being
killed off to fast.
I advised my regular vet of the situation and he did
not note the family pets charts.
Later in 2012, I brought my 4 year old cat (Missy) to
my regular vet for a teeth cleaning. Since she has a
heart condition, I advised the tech to prevent
endocarditis to give her an IV drip during the
procedure of amoxicillin. When I picked her up later
in the day, I learned she had been given a shot of
convenia without my permission! Pfizer says: Do not
administer to cats with heart problems, or anxiety
medication (my cat was prescribed both by the same
vet)! As soon as we got home we started probiotic
therapy. She could not sleep for more than 2
weeks. I politely tried to communicate my
displeasure with the off-label use of convenia and was
met with a letter and medical records for my pets sent
to my home, discharging them from his practice.

Please note: Names have been changed
Dear Dr. SuchandSuch,
Yesterday, our cat Missy visited your office for the
day to have her teeth cleaned by Dr. MoreandMore.
I had left a note on the paperwork, considering
Missy has a heart condition and was about to have
her teeth and gums worked on.
The noted a request for IV antibiotic to "prevent"
endocarditis. We had been treating her with
Amoxicillin daily. I understand that
Amoxicillin is typically used for this type of
Since there was no indication for prophylactic
antibiotic premedication from your office, I felt
that requesting IV antibiotics during procedure for
Missy as a "limited antibiotic therapy" to to
prevent risk of contracting microbial disease during
or shortly after the prophylaxis could be
therapeutic. I left the decision in the hands
of Dr. MoreandMore.
Upon arriving to the office to pick Missy up, I
learned Dr. MoreandMore administered a Convenia
Injection to Missy.
During a prior conversation with you, months back
regarding my other older cat Misses, she had
received a shot of Convenia at Emergency Vet, when
she was urinating blood, with no sign of infection,
Misses has been experiencing seizures ever since and
has severely deteriorated.
I am very upset that Convenia - a long acting drug
was used on Missy with no current sign of infection.
At this current time, Missy has not slept since the
procedure yesterday. She's was meowing all night
(she is usually quiet) and clearly not feeling well
with an elevated heart rate.
Understanding the labelled use for Convenia for skin
infections - this antibiotic works too well in my
humble opinion when introduced to the small animals
without proof of current infection and creates
But also considering the cocktail of bacteria that
Convenia destroys, may provide the idea it would be
appropriate for off-label applications, however I
feel that too many other forms of necessary bacteria
get destroyed in the process, creating risk for
I feel this may be the reason why the FDA only
approved Convenia for its labelled purpose.
It rapidly and continues to kill the good and the
bad bacteria in the body too quickly and remains in
the body for weeks and months creating potential for
complications, including but not limited to death in
As you and I understand, if you get a severe drop of
good bacteria in your body, it can make you very
sick. Think about C-Diff as an
This is what I feel is happening with many animals
for which Convenia is being prescribed for off-label
Not only does it state exactly on the website that
Convenia is to be used for "Skin Infections" but I
have also spoken with Pfizer who said that using
Convenia for preventative purposes of endocarditis
is considered "off-label".
At this time, Missy has been given Benebac and
another combination of Probiotics, with hopes she
will snap out of it. We are going to attempt
to mix a small amount of one of our healthier cats
feces with the food as well.
We are being very aggressive with this and will
continue to be over the next few months.
Dr. Lisa Pierson, DVM urges to not use Convenia for
off-label purposes. It is not a wonder drug
and is inappropriate in many cases.
Please read this article she wrote and contact her,
if you feel necessary.
Also feel welcome to peruse the Facebook group
dedicated to the many who have experienced
complications because of Convenia
I'm pleading with you Dr. SuchandSuch, the owner of
Pet Clinic - please use reservation and only use
Convenia for the labelled purpose for which it was
designed to only treat severe wound / skin
Though Dr. MoreandMore did say you have had much
success with Convenia, do you feel it is worth the
risk - now knowing that two cats in the same
household are having reactions?
I ask that it please be noted on Misses, Missy's and
Barks charts - "No Convenia" - if it has not already
been noted already.
We are very nervous and fearful for her life. I
am overwhelmed with stress, and worry.
Please pray for Missy.
Thank you for your time and consideration to my
Thank you for your comments...
How is Missy getting along -- we tried to call
today and you were too busy
Perhaps you can give us a report
Dear Dr. SuchandSuch,
Lady from your office, had called me while I was
at the dentist. She only advised me that you were
replying to my email. I thanked her and it was
understood that a call back was not necessary.
Missy is currently receiving probiotic therapy 3-4
times a day and is doing a little better.
She is not as vocal and is moving around a bit
more than the first few days.
She has not slept deeply since the convenia
We are still very concerned and keeping a close
eye on her.
Thank you for your concern.
