Convenia Use In A 17-Year-Old Cat

Kimber writes with a question about her kitty: My 17 year old cat got an upper respiratory infection in early April. Last year, he had tremendous trouble with amoxicillin and clindamycin, vomiting 6-8 times after eating even if I gave him yogurt to help with digestion. Therefore, I insisted that something else be used in April. They gave him an injection of Convenia, but now he is sneezing and snarking again, as well as blowing tiny nose bubbles. I know Convenia has some deadly risks and am fearful of tempting fate. What do you recommend be done at this point?Kimber, thank you for the opportunity to write about Convenia. It is such an incredibly useful drug and we use massive volumes of it.

I would have no qualms about using Convenia for our own Martha.

On the Internet you can read plenty of negative material about every drug that has ever been manufactured, US or foreign. I have addressed some of those comments in this post.  Besides, 64% of the medical information on the Internet is either outdated, or outright wrong.

For a variety of cat problems, bacterial respiratory tract diseases included, Convenia is terrific and quite safe. Of course, there is no such thing as a 100% safe pharmaceutical, and a 17-year-old kitty is likely to have other physical and metabolic problems, too.
Age-appropriate laboratory testing should be performed at least every six months on patients in this age group, when possible.

If our Martha, who is also 17 and has kidney disease, were to develop a respiratory tract infection for which Convenia was appropriate, I wouldn’t hesitate to administer it to her.

See you tomorrow, Dr. Randolph.

    i have a 17 yr old cat with hyperthyroidism, kidney disease and bad arthritis in her back legs, she is now incontinent of urine and feces, and recently had a convenia injection for UTI now she looks at me and cries all the time i feel it is time to euthanize her as she isn’t happy. The vet has discussed palliation for pain. what is the best choice?

    • There are only a few choices for pain management for cats. The veterinarian treating your kitty is in the best position to recommend the right choice. If you are unable to control her pain, your decision may be made for you. I am so sorry you are having to face this sadness.

    I have a 14-year old cat with abdominal lymphoma and I’ve been giving him prednisilone, prilosec and chlorambucil for a year and he was fine but recently started peeing outside the litter box and he vomited water a few times. Took him in for bloodwork & urinalysis and he has the beginning of kidney disease. In case of an infection, he was given a shot of convenia. Was fine for a few days but then appetite fell off. He hasn’t eaten anything solid since Tuesday night. It’s now Friday. Drinks water, pees and takes his meds and only got him to drink a little tuna and sardine water. Taking him in later today. He got the shot 8 days ago. I’m concerned that his appetite won’t return.

    • Despite the internet hysteria about Convenia, you have nothing to worry from it. Good for you for taking him back today, because, with all those problems, he can’t afford not to eat. By “abdominal lymphoma” do you mean it’s in his intestinal tract, just in abdominal lymph nodes or lymph nodes and spleen? To read about kidney failure, click here. I’ll say a prayer for your baby, too. Best wishes, Dr. Randolph.

    Dear sir, my best friend has been told that Convenia is needed to treat her cat’s upper respiratory infection. She currently has no income and cannot pay the price of over three hundred dollars to treat her cats. She lives in a urban area a has an outdoor feeding station and so has become responsible for close to a dozen cats and kittens most of whom were abandoned by people who left the animals behind when they moved out. She is not a cat ‘hoarder,’ just a concerned animal lover. Can you suggest a cheaper antibiotic than Convenia, maybe something our local Southern States carries? They do have the liquid penicillin.

    • I feel your pain, Phyllis. Since Convenia came along we no longer carry the most common oral antibiotics we used to use on cats. There is no need, in the vast majority of cases. However, every once in a while we do find a need for one of them. Here is what I suggest: Ask your friend’s veterinarian if he carries liquid amoxicillin or Clavamox. If not, you could call around town to try to find a practice that does, at which time your friend’s veterinarian could just authorize the other clinic to dispense it. Alternatively, your friend’s veterinarian might be able to order just one or two bottles, and he might be willing to do so if he doesn’t have to order a case quantity. Please let me know if one of those options works. Best wishes, Dr. Randolph.
