What is Baytril?

Baytril®, also known as enrofloxacin, is an antibacterial tablet for dogs and cats that is administered for the treatment of diseases caused by certain types of Gram negative and Gram positive bacteria, including those that may cause dermal, urinary, respiratory tract, and dermal infections. Enrofloxacin is described as a synthetic chemotherapeutic agent that belongs to a class of quinolone carboxylic acid substances. It is rapidly absorbed by the digestive tract, which allows it to penetrate into various body tissues and fluids.

What you should know before using Baytril

Before you buy Baytril (Enroflaxacin) online the following factors should be considered:

Tell your veterinarian if your dog or cat has a history of being hypersensitive to quinolones. This medication is not recommended for small and medium dog breeds during their rapid growth phase that occurs between the age of 2 and 8 months. Furthermore, the safety of using enrofloxacin has not been established for large and giant dog breeds during the rapid growth phase.

In addition, the administration of this medication at a dose of 20 mg/kg body weight or greater causes salivation, depression, and vomiting. Additionally, the administration of this dose or higher results in mild to severe fundic lesions upon ophthalmologic examination, which includes a change in the color of the fundus as well as central or generalized retinal degeneration, along with diffuse-light microscopic changes in the retina , and abnormal electroretinograms (e.g., blindness).

Substances that contain metal cations such as iron, magnesium, calcium and / or aluminum may reduce the absorption of quinolone drugs (Baytril) in the intestinal tract. Furthermore, concomitant treatment with other medications that the liver metabolizes may decrease the clearance rates of the quinolone as well as the other drug that is being administered.

The safety of administering this medication to breeding and pregnant cats has not been established.

In humans, excessive exposure to quinolones increases the risk of user photosensitization within a few hours of being exposed to it. Avoid direct sunlight if excessive exposure accidentally occurs.

Quinolone drugs need to be administered with caution to animals with a history of Central Nervous System (CNS) disorders. Although it is rare, this type of medication may cause CNS stimulation that may cause convulsive seizures.

This class of drug has also been associated with cartilage erosions of weight-bearing joints in addition to other forms of arthropathy in young animals.

The use of this medication in cats has been known to adversely affect the retina. Therefore, it should be administered with caution in cats.

  • Diarrhea
  • Ataxia
  • Elevated liver enzymes
  • Seizures in pets with CNS disorders

There have also been reports of mydriasis, retinal degeneration, including retinal atrophy, attenuated retinal vessels, and hyperreflective tapeta, or the loss of vision. However, mydriasis appears to be an indicator for existing or impending retinal changes.

In rare instances, the use of this medication in cats has been linked to retinal toxicity. Therefore, a dose of 5 mg/kg of body weight per day in cats should not be exceeded.
