Description
Elanco Bayrocin Tablets 150mg (Enrofloxacin) for Dogs
Bayrocin 150mg, commonly searched as Bayrocin tablet for dogs, is a vet-prescribed, broad-spectrum antibiotic tablet containing enrofloxacin, used to treat a wide range of bacterial infections including urinary tract infections, skin infections, respiratory infections and infected wounds. Enrofloxacin is also sold internationally as Baytril, the globally known brand for the same molecule, so if your vet has mentioned Baytril, this is the equivalent Indian product. As a prescription antibiotic, it should only be given for a bacterial infection your vet has diagnosed, and for the exact duration prescribed.
🔒 Prescription (Rx) medicine. A valid veterinary prescription is required. Please upload your prescription at checkout. Bayrocin should only be given to the dog, at the dose and for the full duration your vet has specifically prescribed.
About the Brand: Elanco (Formerly Bayer Animal Health)
This 150mg strength is formulated for dogs; a lower-strength Bayrocin tablet for cats (50mg) is also available separately, sized for a cat’s smaller body weight. You may see Bayrocin listed elsewhere as a Bayer product. That is not wrong, historically: enrofloxacin and the Bayrocin brand were originally developed by Bayer Animal Health. In 2020, Elanco acquired Bayer’s animal health division worldwide, and Bayrocin is now manufactured and marketed by Elanco India Private Limited. Some older listings online haven’t caught up with this, which is why you may still see “Bayer” attached to the name. The medicine itself is the same trusted formulation, just under new ownership.
What Bayrocin 150mg Is Used For
Vets prescribe Bayrocin for dogs for a wide range of bacterial infections, since enrofloxacin is a broad-spectrum antibiotic effective against many common infection-causing bacteria.
Urinary tract infections (UTIs): enrofloxacin reaches high concentrations in urine, making it a common first-line choice for dog UTIs.
Skin infections: used as a medicine for dog skin infection, including infected hot spots and wound infections.
Dog respiratory infection: including the secondary bacterial infections that can follow kennel cough, once a vet has assessed the cause. See our guide on kennel cough in dogs for more on that specific condition.
Ear infections: bacterial ear infections, sometimes alongside an ear-specific treatment.
Soft tissue and gastrointestinal infections: as part of a broader treatment plan your vet directs.
Bayrocin treats bacterial infections specifically, it will not help a viral or fungal problem, which is exactly why a vet needs to identify what kind of infection is present before prescribing it.
Important: Not Suitable for Growing Puppies
⚠️ Enrofloxacin, the active ingredient in Bayrocin, is well documented to cause damage to developing cartilage in growing dogs, particularly in the weight-bearing joints. For this reason, Bayrocin and other enrofloxacin-based antibiotics are generally not used in young, still-growing puppies, with vets typically avoiding this class of antibiotic in dogs under roughly 12 months of age, and even longer for giant breeds that keep growing past that. If you have a puppy with a suspected infection, your vet will choose an antibiotic appropriate for a growing dog. Never give Bayrocin to a puppy without your vet specifically confirming it is safe for that individual dog’s age and breed.
How It Works & Composition
Active ingredient
Class
Role
Enrofloxacin (150mg per tablet)
Fluoroquinolone antibiotic
Kills bacteria by blocking the enzymes they need to copy their DNA, stopping the infection from spreading.
Enrofloxacin belongs to the fluoroquinolone class of antibiotics, developed specifically for veterinary use. It works by interfering with an enzyme bacteria need to replicate their DNA, which stops the bacteria from multiplying and allows the infection to clear. It is effective against a broad range of both gram-positive and gram-negative bacteria, which is why it is used across so many different types of infection.
Dosage & Completing the Course
There is no fixed Bayrocin 150 mg dosage for dogs printed here. The right dose depends on your dog’s weight and the infection being treated, and is set by your veterinarian, so please follow your vet’s prescription exactly.
Why finishing the full course matters: stopping an antibiotic early, even once your dog seems better, is one of the most common reasons an infection returns, sometimes harder to treat the second time. Complete the exact number of days your vet prescribed, even if symptoms clear up before then. This also matters beyond your own dog: incomplete antibiotic courses contribute to bacterial resistance, making infections harder to treat for pets generally.
Give at the same time each day, as your vet advised, usually once daily.
Follow food timing as directed, since this can affect absorption for some antibiotics.
Complete the full prescribed course, do not stop early.
Never reuse leftover antibiotics for a different illness or a different pet without a vet’s confirmation, since the wrong antibiotic for the wrong infection does not help and can contribute to resistance.
Vet Tip
🩺 Vet Tip from Dr Devayani (MVSc, 6+ years of experience): If your dog has had a UTI before, ask your vet about a urine culture rather than jumping straight to an antibiotic again, especially for repeat infections. It confirms the specific bacteria and whether it is actually sensitive to enrofloxacin, which matters more than people expect, since using the wrong antibiotic for a resistant bacteria wastes time and can make the infection harder to treat later. It is a small extra step that makes the treatment far more likely to work the first time.
What If You Miss a Dose?
If you miss a dose, give it as soon as you remember, unless it is nearly time for the next one.
If it is close to the next dose, skip the missed one and continue on schedule.
Do not double up to make up for a missed dose.
If your dog has missed several doses during the course, check with your vet rather than just resuming, since this can affect how well the treatment works.
Side Effects & Safety Information
Bayrocin 150 mg side effects are uncommon in adult dogs when used correctly, but a few things are worth knowing.
Not for growing puppies, as covered above, this is the most important safety point for this medicine.
Mild vomiting, loss of appetite or soft stool can occur in some dogs.
Rarely, restlessness or behaviour changes, which should be reported to your vet.
Tell your vet about any other medicines your dog is taking, and about any known sensitivity to fluoroquinolone antibiotics.
Use in pregnant or nursing dogs only on your vet’s specific advice.
If your dog shows any unusual reaction, or the infection is not improving as expected, contact your vet rather than continuing unchanged.
Storage & Handling
Store Bayrocin in a cool, dry place away from direct sunlight, and keep it out of reach of children and other pets. Do not use beyond the printed expiry date, and ask your pharmacist how to dispose of any leftover tablets safely rather than keeping them for future use.
Substitutes & Alternatives
If your vet prescribes a different enrofloxacin brand, or you are comparing options, these are comparable products on Supertails. Always use the specific product your vet recommends.
Vetoquinol Meriquin 150mg (Enrofloxacin) (Rs 145): another well-known enrofloxacin brand, therapeutically equivalent at the same strength.
Sihil Enrosil 150mg (Enrofloxacin) (Rs 141): a comparable enrofloxacin tablet.
Skyec Endro Pet 150mg (Enrofloxacin) (Rs 113): another enrofloxacin option at a similar strength.
Since all of these contain the same active ingredient at the same strength, the choice between brands usually comes down to your vet’s preference or availability rather than a real difference in how they work. Browse the full antibiotics for dogs range for more options.

FAQs
What is Bayrocin used for?
Bayrocin 150mg is a broad-spectrum antibiotic tablet for dogs containing enrofloxacin, used to treat bacterial infections including UTIs, skin infections, respiratory infections, ear infections and infected wounds. It should only be given for a bacterial infection your vet has diagnosed, since it does not help viral or fungal problems.
Is Bayrocin safe for dogs?
Bayrocin is safe and widely used in adult dogs when prescribed by a vet at the correct dose and for the right duration. It is not suitable for growing puppies, since enrofloxacin can damage developing cartilage in young dogs. Most adult dogs tolerate it well, with mild vomiting or appetite changes being the most commonly reported reaction.
What types of infections are treated with enrofloxacin in dogs?
Enrofloxacin, the active ingredient in Bayrocin, treats a broad range of bacterial infections in dogs, including urinary tract infections, skin and wound infections, respiratory infections and some ear infections. Your vet will confirm it is the right choice for the specific bacteria and infection your dog has.
What is the price of Bayrocin tablets?
Bayrocin 150mg tablets are priced from Rs 143 on Supertails, with a 50mg strength also available from Rs 55. Since this is a prescription medicine, you will need to upload a valid vet prescription at checkout for either strength.
Can I give Bayrocin to puppies?
Generally, no. Enrofloxacin is known to cause cartilage damage in the weight-bearing joints of growing dogs, so vets typically avoid this antibiotic class in puppies, often up to around 12 months of age or longer for large and giant breeds. Only give it to a puppy if your vet has specifically confirmed it is appropriate for that individual dog.
Bayrocin vs Baytril: is Bayrocin the same as Baytril?
Both contain the same active ingredient, enrofloxacin. Baytril is the globally known international brand name for enrofloxacin, while Bayrocin is the equivalent product manufactured for the Indian market by Elanco. If your vet mentioned Baytril, Bayrocin is the corresponding product available in India.
How long should I give my dog antibiotics for?
For exactly as many days as your vet has prescribed, even if your dog seems better before the course is finished. Stopping early is one of the most common reasons an infection returns, sometimes more difficult to treat, and it also contributes to antibiotic resistance. Never extend or shorten the course without checking with your vet.
What is Bayrocin 1 Shot, and is it the same as the tablets?
Bayrocin 1 Shot is a different, injectable formulation of enrofloxacin, given by a vet rather than at home, and is not the same product as the Bayrocin 150mg tablets on this page. If your vet has recommended an injectable antibiotic, that is a separate discussion to have with them directly, since this page covers the oral tablet form only.
