It has antibacterial activity against a broad spectrum of Gram negative and Gram positive bacteria. Each mL of injectable solution contains: enrofloxacin 22.7 mg n-butyl alcohol 30 mg potassium hydroxide for pH adjustment and water for injection q.s. Item Specifications: For Use: Dogs Only Manufacturer: Bayer Animal Health INDICATIONS: Baytril® (brand of enrofloxacin) Injectable Solution is indicated for the management of diseases in dogs associated with bacteria susceptible to enrofloxacin. CONTRAINDICATIONS: Enrofloxacin is contraindicated in dogs known to be hypersensitive to quinolones. Based on the studies discussed under the section on Animal Safety Summary the use of enrofloxacin is contraindicated in small and medium breeds of dogs during the rapid growth phase (between 2 and 8 months of age). The safe use of enrofloxacin has not been established in large and giant breeds during the rapid growth phase. Large breeds may be in this phase for up to one year of age and the giant breeds for up to 18 months. In clinical field trials utilizing a daily oral dose of 5.0 mg/kg there were no reports of lameness or joint problems in any breed. However controlled studies with histological examination of the articular cartilage have not been conducted in the large or giant breeds. DOSAGE AND ADMINISTRATION: Use as Directed by Your Veterinarian CHEMICAL NOMENCLATURE AND STRUCTURAL FORMULA: 1-cyclopropyl-7-(4-ethyl-1-piperazinyl)-6-fluoro-1 4-dihydro-4-oxo-3-quinolinecarboxylic acid. EFFICACY CONFIRMATION: Clinical efficacy was established in dermal infections (wounds and abscesses) associated with susceptible strains of Escherichia coli Klebsiella pneumoniae Proteus mirabilis and Staphylococcus intermedius; respiratory infections (pneumonia tonsillitis rhinitis) associated with susceptible strains of Escherichia coli and Staphylococcus aureus; and urinary cystitis associated with susceptible strains of Escherichia coli Proteus mirabilis and Staphylococcus aureus. CAUTION: Federal law prohibits the extralabel use of this drug in food-producing animals. ADVERSE REACTIONS: No drug-related side effects were reported in 122 clinical cases treated with Baytril® (enrofloxacin) Injectable Solution followed by Baytril® tablets at 5.0 mg/kg per day. For medical emergencies or to report adverse reactions call 1-800-422-9874. ANIMAL SAFETY SUMMARY: Adult dogs receiving enrofloxacin orally at a daily dosage rate 52 mg/kg for 13 weeks had only isolated incidences of vomition and inappetence. Adult dogs receiving the tablet formulation for 30 consecutive days at a daily treatment of 25 mg/kg did not exhibit significant clinical signs nor were there effects upon the clinical chemistry hematological or histological parameters. Daily doses of 125 mg/kg for up to 11 days induced vomition inappetence depression difficult locomotion and death while adult dogs receiving 50 mg/kg/day for 14 days had clinical signs of vomition and inappetence. Adult dogs dosed intramuscularly for three treatments at 12.5 mg/kg followed by 57 oral treatments at 12.5 mg/kg all at 12 hour intervals did not exhibit either significant clinical signs or effects upon the clinical chemistry hematological or histological parameters. Oral treatment of 15 to 28 week old growing puppies with daily dosage rates of 25 mg/kg has induced abnormal carriage of the carpal joint and weakness in the hindquarters. Significant improvement of clinical signs is observed following drug withdrawal. Microscopic studies have identified lesions of the articular cartilage following 30 day treatments at either 5 15 or 25 mg/kg in this age group. Clinical signs of difficult ambulation or associated cartilage lesions have not been observed in 29 to 34 week old puppies following daily treatments of 25 mg/kg for 30 consecutive days nor in 2 week old puppies with the same treatment schedule. Tests indicated no effect on circulating microfilariae or adult heartworms (Dirofilaria immitis) when dogs were treated at a daily dosage rate of 15 mg/kg for 30 days. No effect on cholinesterase values was observed. No adverse effects were observed on reproductive parameters when male dogs received 10 consecutive daily treatments of 15 mg/kg/day at 3 intervals (90 45 and 14 days) prior to breeding or when female dogs received 10 consecutive daily treatments of 15 mg/kg/day at 4 intervals; between 30 and 0 days prior to breeding early pregnancy (between 10th 30th days) late pregnancy (between 40th 60th days) and during lactation (the first 28 days). DRUG INTERACTIONS: Concomitant therapy with other drugs that are metabolized in the liver may reduce the clearance rates of the quinolone and the other drug. Enrofloxacin has been administered to dogs at a daily dosage rate of 10 mg/kg concurrently with a wide variety of other health products including anthelmintics (praziquantel febantel) insecticides (pyrethrins) heartworm preventatives (diethylcarbamazine) and other antibiotics (ampicillin gentamicin sulfate penicillin). No incompatibilities with other drugs are known at this time. WARNINGS: For use in animals only. The use of this product in cats may result in Retinal Toxicity. Keep out of reach of children. Avoid contact with eyes. In case of contact immediately flush eyes with copious amounts of water for 15 minutes. In case of dermal contact wash skin with soap and water. Consult a physician if irritation persists following ocular or dermal exposure. Individuals with a history of hypersensitivity to quinolones should avoid this product. In humans there is a risk of user photosensitization within a few hours after excessive exposure to quinolones. If excessive accidental exposure occurs avoid direct sunlight.

PRECAUTION: Quinolone-class drugs should be used with caution in animals with known or suspected Central Nervous System (CNS) disorders. In such animals quinolones have in rare instances been associated with CNS stimulation which may lead to convulsive seizures. Quinolone-class drugs have been associated with cartilage erosions in weight-bearing joints and other forms of arthropathy in immature animals of various species. The use of fluoroquinolones in cats has been reported to adversely affect the retina. Such products should be used with caution in cats. STORAGE: Protect from direct sunlight. Do not freeze.
