Understanding the problem?

This medicine is a long-acting antibiotic given as injectable to cats under infectious conditions like skin conditions, UTIs, and others. However, reported cases with the injection site had shown inflammation, sarcoma, and tumor signs. At times, it is recommended as an oral route if tolerated well by the patient. Also, it is available in the form of patches but not free of local side effects.

Some of the issues reported by its use include scabs, necrosis, and alopecia. The service is seen frequently with pet owners and finding names from convenience in use. But until cat deaths from convenia were reported.

Sometimes rescue is seen by presenting arguments in the failure of compliance of the drug schedule by the pet owners. The need to follow a plan and to medicate consistently fails in most cat owners. Thus, it can, in turn, causes drug resistance as one fails to receive antibiotics. Leaving the vets with the option of convenia to get through this issue. Thus, the easier way is always appealing, while other possibilities include more straightforward options like Clavamox and amoxicillin.

Is convenia the best choice?

The drug of such controversy is weighed in terms of award versus risk. The side overweighing wins the contest. But provided that safer and better options are available, one should go for them irrespective of convenience or price. Other antibiotics are generally are the safer options here for feline infections.

Convenia as medicine is selected, keeping the interest and condition of the patient in mind. The vet prescribing convenia never writes it on the prescription pad without discussing it with the cat parent. The vet prescribed it usually has an experience with its use and might not have any grave consequences.

Usually, the cat owner later sees the effect and is responsible for reporting any health concerns observed with medicine in the cat. Thus, a piece of advice here would be to discuss with the vet before using convenia as an option here. Usually, people get to see the name on the bill post damage done. It is administered to cat’s post-dental procedure. A thorough verbal communication firsthand will be good if you are convinced not to use convenia. In dire cases, you can get the vet to the right in a red box or with a red indicator saying no convenia.

Convenia treating UTIs

Cats complaining about urinary tract issues are usually catered for the inflammation and are prescribed antibiotics. The cat parent and the vet assume that it is an infection requiring no less than anti-bacterial treatment. The common symptoms they notice in this case include little or no urination, cat seen licking the genitals, sometimes urinating with blood in the urine, or urinating randomly at different locations.

These all symptoms are loosely attached to a bladder infection. Ignoring the fact that it could be mere inflammation, requiring comparatively lighter or simple treatment.

More than 90% of the chances are cat has sterile cystitis. Here sterile denotes the absence of infection or microbes, requiring no antibiotic but just anti-inflammatory medicine. The point of error here is recommending medication without any sensitivity test and going for the third-generation antibiotic bluntly. To save oneself from repetitive dosing, the vet also recommends convenia in this case. And dismissing the dire consequences that can come along here.

When one ends up recommending convenia or any other antibiotic, it results in causing resistance in the bacteria and greater chances of superinfection. The threat remains the same for both man and animal alike with the development of resistance species, requiring more potent antibiotics in the future to have a similar effect.

In short, many cats receive unnecessary antibiotics, convenia to be particular, ignoring cat deaths from convenia.

    • My cat of 9 years was given this injection without any teaching from the vet at all the vet treated her for a bladder infection without completing a urinalysis. She passed away 6 months later due to no appetite, lethargy, weight loss and many abnormal labs and Sarcoma. I brought her in three times in a three month period and medical exams were very incomplete until I had to tell the vet what to check . I believe the antibiotic caused her death due to side effects. She was a very healthy cat until she received this injection very poor care by the vet

    • I’m so sorry for your loss. I’m on this site for Covenia because just today I brought my 16 yr old cat to the emergency vet for what I believed to be a UTI. Although an ultrasound showed that her bladder appeared to be inflamed, it was very small (no urine), no stones or masses. Because there was no urine in her bladder, they couldn’t do a urinalysis but would prescribe an antibiotic anyway. Since she is very difficult to pill, I asked if they could just give her an injection instead. I wasn’t told what it was and didn’t know until I got home and looked at my bill. When I looked up Covenia I was horrified to see that it causes death in cats!! WTH! Why is it still being prescribed?! I am so scared now that I am going to lose my beloved cat that I’ve had for 16 years since she was kitten. How can we stop this from happening to someone else? What did you do? Again, my deepest sympathies to you. I know all to well the pain of losing a beloved pet. ❤️❤️

      • I have contacted the FDA as recommended by the web site “cat info” but have not heard anything yet also the manufacturer but again haven’t heard anything that’s seven months ago. I have read an necropsy would have to be completed for confirmation but wouldn’t do that to my dear beautiful Daisey. I am heartbroken as anyone would be with such a loss. I contacted the vet but he never responded again no information was given to me about the shot it was given and then I was informed. I wasn’t even asked if she was difficult to pill. She had never been sick and the only medication I gave her was pain med after her spay and she did just fine it was liquid. What I learned about this antibiotic and any injectable’s was to late for my sweet girl. Of course I blame myself for not being aware all of my prior cats never had problems put then never given this antibiotic Convenia.

      • I would also recommend if your cat stops eating or becomes less active have her seen and have blood work done to check kidney function, and complete blood work done. As I have posted I took my cat in three times and didn’t speak up until it was to late, antibiotics are hard on the kidneys especially a long acting injectable like Convenia can be very hard on the kidneys. Also give probiotics, antibiotics kills the good bacteria as well as bad in the gut. Also causes anemia my cats blood work was so abnormal after three trips to the vet and I had to request blood work the third time. Blood work will give you and idea how healthy your cat is

    • I believe before the antibiotic Convenia or any antibiotics blood work should be completed to evaluate especially the kidneys before administering medications. This is what I learned to late for cat but put full trust in the vet. Loosing an animal to a medication that’s suppose to heal is very heart breaking.

    • Hi so sorry for the loss of your special companion your lovely cat. I had just been reading about convenia before I saw your post and it said it’s not recommended in cats with kidney disease. I don’t like any long acting drugs personally and prefer to administer daily it may not be as convenient but I feel if there is any reaction it can be stopped straight away.
      Hope you’re OK I know how hard it is to lose a beloved best friend x

      • When my cat was administered Convenia injection the Vet administered it then told me never questioned me whether I could administer medications by mouth or not. My cat had never received an antibiotic before the Convenia. It’s my understanding after research another antibiotic should be attempted first before the Convenia. At least one can stop an oral antibiotic but not an injectable. I have tried to contact the Vet never able to speak to him or get answers to my questions so many things were not done according to what I researched. I also believe where my cat received her injections were not the recommended sites to prevent possible Feline Injection Site Sarcoma.

  3. I’m really freaking out now as my cat just had a covenia injection on May 19, 2022. She has been sleeping mostly but not eating all that well. She also has ear drops twice daily which she hates. I’m just concerned now for her since she got that injection for possible skin infection and she’s never Been on meds before. I’m so sorry for everyone’s loss and will pray my cat don’t have problems with this antibiotic. If she does you will hear from me again. Guaranteed!! God bless you all for sharing.
