Can Convenia Cause Blindness In Cats

These are not side effects of Convenia. If they do occur, a veterinarian should check them out. Injecting baytril intravenously too fast and/or with inadequate dilution (minimum 1/3) can cause neurological symptoms such as dysnea (difficulty in breathing), ataxia and/or blindness.

Sometimes, there are reports of neurological symptoms like seizures and incoordination. However, these are rare. Convenia can sometimes cause bone marrow damage and reduce the production of red blood cells. However, this is an extremely rare side effect.

What do people think? What Can Cause Blindness in Cats?

  1. Side effects are a part of all drugs. I have heard of blindness in dogs and cats after Baytril was given. Convenia is different from other antibiotics like Batyril in that it stays in the system up to two years and you can’t stop it once it’s been given. Baytril and all other antibiotics are only effective for between 12-24 hours. This does not negate the possibility of side effects. However, it reduces risk and allows for faster intervention in case side effects occur. It is always about weighing the benefits and risks of any drug.
  2. Injecting baytril intravenously too fast and/or with inadequate dilution (minimum 1/3) can cause neurological symptoms such as dysnea, ataxia and/or blindness. Your veterinary ophthalmologist should be consulted regarding the dosage, including how it was administered (IV), and if it was diluted.
  3. You can search Google for “cat baytril blindness”, and it will bring up more results.
  4. I would contact your Vet to discuss this first ……….. thing and I would take my cat to the nearest Vet Ophthalmologist as soon as possible.
  5. Tomorrow morning, we will see the Ophthalmologist. We’ll hopefully get some answers. Our cat is not a patient. They mentioned that she would need to be sedated again for the exam. This is something I am dreading. I am terrified of her reactions, as we don’t know why she is blind.

What the Vet Speaks

My name is Alexa. I have more than 20 years experience as a vet. I am sorry to hear that Charlie has been lethargic since he was treated for an eye infection.

Convenia, a cephalosporin-based antibiotic, is the short answer. This antibiotic class is well-known for causing stomach upsets such as nausea and weight loss.

But I wouldn’t expect the effects of a Convenia injection lasting this long. Usually, we experience nausea and loss of appetite for a few days. It is absurd to believe that one Convenia injection can be the sole cause of his symptoms.

Eye infection signs

  1. Ocular discharge (discharge of the eyes) can range in colour from clear and green-yellow. It may dry to form an opaque crust.
  2. Excessive tears production
  3. Eye swelling
  4. Red swollen conjunctiva
  5. Clouding of the eyes


Eye drops and ointments are commonly used to treat eye infections. They usually heal quickly. To avoid further discomfort and to reduce the chance of blindness, seek veterinary advice immediately after any ocular changes are noticed.

Cats that are blind

Blindness in cats can happen suddenly, but it is usually gradual. Owners may not be able to see if their cat is blind. However, there are signs and behavior changes that can indicate that the cat is experiencing difficulty seeing.

  • They walk very close to the walls
  • They are reluctant to run or jump.
  • They hide.
  • They walk with their legs slightly wider than normal, and they are cautious.
  • Their movements are more awkward and unpredictable.

Cat Blindness Causes

Blindness can occur in many ways in cats. Some will lead to gradual vision loss. In these cases, the cat often adapts to the reduced sight very well, showing little to no signs of difficulty. If the blindness progresses rapidly, the cat will not be able to adjust and may become disoriented and confused.

  • Cataracts

Cataracts, which are the most common cause of vision loss, are caused by the loss of transparency in the crystalline lens (the eye’s natural lens). Blindness can be more or less severe depending on how much opacity is present. Continue reading to learn more about cataracts and cats.

  • Blindness due to Iatrogenic causes

In this instance, the cat is blinded by anoxia or hypoxia during surgery.

  • Trauma

Cats can lose their vision due to damage from accidents such as retinal detachments or eye injuries.

Does Convenia Have Any Aspect Outcomes In Cats?

Convenia has no adverse effects on cats, but almost all medications have a long list of possible negative outcomes. Convenia isn’t any totally completely different. This is one reason why so many medications are prescription-only. Vets must weigh the suitability of a product for an individual affected individual. They should also consider potential adverse outcomes for other optimistic individual animals.

Side effects of constipation

Convenia is a veterinarian-prescribed antibiotic medication indicated to treat certain types of bacterial infections in cats and dogs. It is administered subcutaneously under the skin and lasts up to 14 days according to Pfizer, the pharmaceutical distributor for this medication 2.. Convenia can only be given to cats and dogs who are at least four months old.

1) Nausea Or Vomiting

Cats and dogs can experience upset stomach side effects such as nausea and vomiting after receiving Convenia. reports that vomiting was seen in about 5% of dogs and 8% of cats during clinical trials. A temporary decrease in appetite may also be caused by upset stomach side effects. Pet owners might notice that their pet doesn’t like eating at meals or is reluctant to eat certain treats. These side effects usually disappear within a few days.

2) Diarrhea

Convenia may cause diarrhea side effects, reports 3. Pet owners might notice that their dogs are being let out more often than usual and need to keep the litter box clean. Some pets might accidentally stain furniture or floors due to diarrhea side effects depending on their severity.

3) Fatigue, Lethargy reports that approximately 4 percent of dogs and cats treated with this medication experienced lethargy during clinical trials. The affected pets may appear tired or not as playful as they normally are. warns that Convenia can cause unusually hyperactive behavior in cats. These side effects usually resolve within a few hours after initial treatment with Convenia.

Cats with blindness

To effectively treat your cat’s blindness, it is crucial to understand the cause. Blindness in cats can often be reversed if the problem is treated promptly. If your cat seems to have trouble seeing or is clumsy than usual, it’s worth contacting a veterinarian immediately.

High blood pressure is the leading cause of blindness in cats, as we have mentioned. Antihypertensive medications are required to treat it.
