thanks for the post...will keep bumping it up to keep it current...I want everyone to read!!!
If anyone ever suggests this drug to my current cat or any future cats, I will definitely tell them I don't want to use this drug. It's kinder to put a cat to sleep in a hopeless case than to put a cat through all of that.
My cat recently passed away just 10 days after receiving Convenia.
I read your article AFTER the vet administered this drug for rhinitis. I wish I read it sooner... I would have never allowed Convenia. The vet said they "have good luck with this drug", no counter indications, no side effects to worry about. My cat Cloud was 16 years old. He began coughing and sneezing in April, and when I saw blood droplets in the sneezing I tool him to the vet. He dad strong heart, the air was going to the lungs, his temperature was normal, but he lost weight. The vet suggested MRI thinking it is cancer. He recommended Convenia thinking there was an infection. I think, after many sleepless days and nights since then, that there was something in the cheep litter I buy usually from no-name supermarket No-Frills in Toronto. I noticed that all 3 of my cats were sneezing more frequently after the new box of litter. The other 2 cats got over it and I returned the product. Cloud was not so lucky. He probably did have an infection because he started to eat less and even passed on his favorite shrimp... After Convenia sneezing stopped in 48 hours, there was no running nose. My joy did not last. On the third day Cloud became lethargic, hardly ate. On the fourth day he did not eat or drink but secluded himself. I called the vet and laid on him everything I read about Convenia. He did not know that it stays in the system for 65 days, was unaware of Phizer's "foreign market experience" and stood by his diagnosis of co-morbidity. Cloud showed no signs of any disease, he was playful and active throughout his episode with coughing and sneezing. For sure he had an infection that interfered with his smell but it was not viral, my other cats are fine. Convenia killed Cloud. The name sais it all. It's the vet's delight. It is the source of self blame... Thank you for posting the truth about Convenia. I will now report adverse events to Pfizer and to the FDA
I am very sorry for your loss Alexander, thank you for sharing Clouds story with us....we all have to keep getting the word out there for everyone to be aware of.
We trust our Vet's and treatment of our babies thinking they are in the know, however like with any medication even the ones we humans are prescribed...we need to be vigilant and informed.
God bless little Cloud, may you RIP...knowing you were loved♥
My cat, which I consider my child received one dose of Convenia yesterday afternon at 2pm. I had my husband go without me, since I was unable to. What a mistake that was. My husband never cared to ask what is the safest way of treating an abscess in the front leg. I would have asked the doctor to confirm what bacteria is he infected with, so the correct antibiotic, if needed, is given. So pissed!!! He was given the injection, then my husband was told to give Orbax; another type of antibiotic; I guess a double whammy. Why not just confirm infection with bloodwork and have the abscess lanced and drained? I would have paid the money. I will update you all. I will go to the media if my cat is affected in any way. And to know Convenia stays in the system for over 60 days????? My husband should have been warned.
don't blame your husband dear, most Vets aren't aware or don't recognize there is an issue with convenia....takes tons of complaints before they wake up and listen.
I just hope your baby isn't one that reacts to this horrible medication, many are okay with it....so lets just keep our fingers crossed, keep a close watch on him especially for excessive lethargy, don't know if there is an antidote..but be sure and ask just in case...
good luck to your dear sweet baby...keep us posted....
I can promise you this, opus88, if my cat comes out just fine, I still care about other cats out there. I will research and call multiple vets in my community. I will update everyone on how educated the vets are in South Florida. Right now, Blu is responding well. He is back to his usual self. He has not lost his appetite; he is going potty normally; no nausea. His abscess is 50% smaller now. I am still hoping the 64 days goes by fast since I heard Convenia stays in system that long. Thank you, opus88. P.S If one knows if a med stays in your system for over 30 days, then a doctor needs to make sure beforehand if cat will have a reaction. The pet owner should also be given other alternatives.
good for you!!!!!!!!!!!!!!!
you are so very right, a pet owner should always be made aware of any negatives about any medication....always!!
so happy your boy is tolerating it well and is coming along so good.....great news:))
My 12 year old female shepherd cross was given Convenia( one injection) for a small hot spot skin infection on her abdomen in Feb. 2013. I would have been satisfied with giving her oral Keflex for 7-10 days to treat this condition as she has been on this antibiotic before with no ill effects. However, the Vet treating my dog suggested "Convenia". One time injection and stays in the system for approximately 2 weeks according to the vet. Easy/ breezy according to the Vet. She had also had baseline blood work done and yearly vaccines completed with this visit as well.
Happily I went home with my dog thinking she is covered. Well, not more than 24 hours later, my dog was weak, stunned and could hardly walk. She did not appear to respond to the calling her name or to go outside. She fell off the second step of our deck and appeared very confused as to her environment. She also appeared very lethargic and no appetite.
Called our Vet(as I had trusted the care provided for many years) and said that I thought something was seriously wrong since the visit the day before. The Vet said that they were unsure what the sudden deterioration in condition could be from. Really???
Only thing new....Convenia. She almost died as her kidneys and liver values went through the roof. I was so upset that I had not asked more questions. Our dog had several hospital admissions, IV fluids and Cerenia to alleviate the nausea so she might start eating again. Then followed the associated weight loss. We were so frightened that we were going to lose her. and serious discusion that it might be best to euthanize her if she does not improve..once again..really???? I asked the Vet on numerous occasions during her related hospital stays that I thought that the Convenia made her sick . The research that I did about Convenia after my dog got sick in fact made me believe that the drug made her ill. Many comments posted about the owners and their pets demonstrates that this Convenia drug used is unsafe. Our Vet side stepped /avoided any discussion about the fact that the drug may in fact made our dog so sick she almost died. How does an animal have a chance when it stays in the system for up to 60 days and there is no way to reverse the effects of this drug. I am usually very stringent about my pets and any drugs/ treatments. This one time, I trusted my Vet to keep my dog safe and do no harm. The Vet's only response was "all drugs have potential side effects" and assured me it was safe and had good results when used in cats?????? I can thankfully say our dog survived this horrible ordeal and seems to be herself again. To those who have lost your precious pets..my heartfelt thoughts are with you.
The lesson in all this... I will never blindly trust again. My dog almost died . Hope this helps someone out there.
thanks for posting about your experience, so glad your dog was okay. I hope you will also post this in the Dog community, heres a link. thanks again
Thank you for posting this. My dog was going to have Convenia tomorrow. I will stick with the pills. I am so glad I read your post. If you think about it, who is making more money when the drug causes all these medical problems.
Sadly, our 12 year old female Shepherd cross was euthanized on July 6/2013. We believe that she truly never recovered from the Convenia she received in February 2013 which did irreparable damage to her liver and kidneys. She was a wonderful rescue with unwavering loyalty. We will miss her greatly.
Lesson in all of this once again....ask questions(and lots of them) and do your research. Vets are not about to bash pharmaceutical companies who are their suppliers. Lastly, once again...I hope this helps someone out there.
I am so sorry for your loss, ready218. Thank you for sharing your story here.
Hugs to you~
Our kitty Worf just had a Convenia injection yesterday, and today had diarrhea and vomiting after meals. I took him back, armed with the information that my husband researched this morning, and told the vet that Convenia has been found to be unsafe and potentially causes death. The vet said not to believe everything on the internet, and that they had found the Convenia had never caused any problems that they had been told of and had considered adverse reactions to be extremely rare. I, too, had not been told of the possible side effects, I had only taken Worf in due to trouble urinating....I had thought he had crystals possibly.
They re-hydrated him, and gave him something for his upset tummy, and some easy soft food to eat. He seems to be ok for now, but I am still holding my breath for the next few weeks based on what I have read in the previous posts...my heart goes out to the mommies and daddies of those who have passed away.
Hi there. Please try not to panic. The incidents ARE likely to be sporadic in comparison to how often this drug is given...which is no consolation to the owner who lost their dear pet. I am not advocating this drug in the least, just being realistic. I think this drug should be removed from the market simply due to the longevity it stays in the system. If the pet should have a reaction, they hardly have a chance. I have a note in my kitty's records not to be given Convenia.
I will be keeping your Worf in my prayers. Please keep us posted.
Thanks Jade, inspite of all that I wrote, I actually believe that if I concentrate on thinking that Worf is so sick, that it can manifest it to be true...energetically speaking. I keep telling him that he's going to be fine, I keep petting him and telling he's a handsome boy and that his kitty brother Sparky loves him too.
Thanks for you kind support Jade, I will keep the board posted.
Yes, a self fulfilling prophecy; I believe in that, too. Just keep positive like you're doing, and we will too.
...and welcome to the forum! :)
I hope that your "handsome boy" will be okay. I am sorry to hear about these difficulties and adverse related effects possibly linked to Convenia usage. I am deeply concerned about supposed "safety margins " claimed by those who supply and to those who administer this drug to animals. You are being thought of in hopes of a speedy recovery for your beloved feline. . I can truly relate to what you are going through. Stay strong.
I am so worried! 1 week ago our cat of 16 years was given a shot of covenia for a rash on her leg. That evening she started acting strange, wouldn't move out of one spot, stopped urinating in her litter box, and was lethargic. I have been watching her and even asked the vet what was going on. Last night I noticed she was falling when she walked, couldn't see very well, and was very sick. Took her to the vet and just got a call from them. they said that Covenia could not have caused any of this, she has some neurologic problems, bleeding behing her right eye and some behind her left, can't see out of right eye and very little out of left, can hardly walk, can't see to drink, etc... Let me remind you she was fine prior to the doctor giving her this shot for a rash. I am so lost!!!! Has others seen this happen to their pets?
please scroll to the top of this post and read all the remarks about convenia, its a very dangerous drug...many cats and dogs have severe reactions to it and b/c it remains in their systems so long it doesn't clear and allow the poor animal to recover...
the symptoms you describe are a very serious reaction....I am very sorry.
Your Vet is either not reading reports of these negative reactions or he is refusing to believe the truth right in front of his nose...
I am not a doctor however it will be very difficult if not impossible for a kitty of 16 to overcome such a severe reaction....I hope you won't allow your kitty to suffer.
again let me stress how sorry I am to read this and to once again hear of a kitty given this terrible drug...
((hugs)) to you both.
I agree it is always kinder to do that. However, in Angie's case and in many other cases where comprimised cats or dogs were given Convenia and had severe reactions we will never know now if other treatments could have saved them or extended their lives and how much damage Convenia actually did.
