Baytril 50 Injection is a prescription antibiotic from Elanco, used by Australian vets to treat bacterial infections in companion animals. Supplied as a 50mg/mL injectable solution in a 50mL vial, it is dispensed only against a current veterinary prescription and administered under veterinary direction. Not a product you buy off the shelf — your vet decides whether it is appropriate for your pet.

The active ingredient is enrofloxacin, a fluoroquinolone antibiotic that works against a broad range of gram-negative and some gram-positive bacteria. Vets reach for it in cases such as respiratory, urinary, skin and soft tissue infections where susceptibility testing or clinical judgement supports a fluoroquinolone. Dose, route and course length are set by the treating vet based on the patient, the infection and the animal's weight.

Owners end up with Baytril 50 because their vet has prescribed it specifically for their animal. Buying through a licensed Australian pharmacy means the medication is stored, handled and dispensed to veterinary standards, with the correct strength and pack size matched to the script.
