Enrofloxacin + Ketoconazole + Triamcinolone: adverse event reports
All products with this ingredient combination · not in an FDA-approved animal drug
- Mostly dog reports
- Auricular (Otic) route most often
- Brands masked by FDA
97 adverse event reports in FDA's database list a drug whose active ingredients are recorded as the combination enrofloxacin, ketoconazole and triamcinolone. The earliest was received in August 2012, the latest in March 2026. It is not the active ingredient of an FDA-approved animal drug; it reaches animals through human-label or compounded products.
openFDA masks the brand and manufacturer in every report, so these figures describe the ingredient combination across all products and cannot be attributed to a brand.
In the 12 months to March 2026, 17 reports named it, up 89% from 9 in the 12 months before. Recent months are provisional: fDA posts reports quarterly with a delay of three to six months, so the newest months are incomplete and usually grow in later releases. Over its whole reporting history that is about 7 reports a year and 0% of all 1,357,245 reports (0% of all dog reports). How many animals received it is not published, so a count says nothing about how often a problem occurs per dose.
The signs named most often are lack of efficacy - NOS (17.5%), deafness (16.5%) and vomiting (14.4%). A report can list several signs, so shares add to more than 100%; 198 different terms appear across these reports. Lack of efficacy - NOS appears in 17.5% of these reports, a larger share than in the pooled reports for every drug containing triamcinolone (13.1%).
93.8% of reports concern dogs. Not every report describes illness: 15.5% were filed wholly or partly as lack of expected effectiveness. Of reports that state seriousness, 41.8% were classed as serious, and 5.2% of all reports record a death or euthanasia as an outcome, as reported. FDA has not necessarily determined whether any drug played a part.
Monthly reports by species, five years
Reports by the month FDA received them. Each panel has its own scale; the peak month is printed at the top right. The newest months are incomplete because FDA posts reports with a delay of three to six months.
Reports by year received
2026 covers reports received through March 2026 only.

Top 30 of 198 coded terms (VeDDRA, the veterinary reporting dictionary; plain-language gloss in brackets). One report can list several terms. The ticks show how often the same term appears in a wider pool of reports; they describe the reports, and FDA cautions that such figures cannot be used to estimate risk or to compare one product with another. openFDA masks brand and manufacturer names in adverse event records, so the reports counted here cannot be attributed to a particular brand.
Outcomes and report types
Outcome recorded in the report
What kind of report it was
Coloured bar: reports naming enrofloxacin + ketoconazole + triamcinolone. Grey bar: all 1,357,245 reports in the database. Outcomes are the status at the time of the last report, as stated by the reporter; a report covering several animals can carry more than one outcome. FDA has not necessarily determined whether any drug played a part in any outcome.
Species and breeds in the reports
Single-breed animals
Breed shares follow how common each breed is. Crossbred animals and reports with no breed stay in the species figure only.

The triamcinolone pool is every report naming triamcinolone alone or in any combination; this combination accounts for 20.2% of it. Shares are of reports, not of animals treated. The number of doses sold is not public, so none of these figures is a rate of occurrence, and differences between columns reflect which animals receive a drug and who reports as much as anything else.

Listed for navigation, ordered by report count. FDA states that these data "cannot be used to estimate the risk associated with the product or compare one drug or device product with another": drugs differ in formulation, in the animals they are given to, in sales volume and in years on the market. A report's ingredient field can be incomplete, so reports about one product may sit under more than one set.
FDA-approved products (Green Book)
Reference information, not report statistics. openFDA masks brand and manufacturer names in adverse event records, so the reports counted here cannot be attributed to a particular brand. The list below is the FDA Green Book as of 1 Oct 2026; nothing on this page says which of these products, if any, a report concerned.
The Green Book lists no approved animal drug with these ingredients. Reports reach FDA for human-label and compounded drugs that veterinarians prescribe.
Species are the major species the Green Book search lists for the application ("—" where it lists another species or none). Approval dates are not part of the Green Book listing files and are not shown. Pioneer applications (NADA) come first, then generics (ANADA).
Questions about enrofloxacin + ketoconazole + triamcinolone reports
How many adverse event reports has FDA received for the combination enrofloxacin, ketoconazole and triamcinolone?
97 reports record a drug with the combination enrofloxacin, ketoconazole and triamcinolone as its active ingredients in the openFDA release of 28 Sep 2026, covering reports received through March 2026. 17 of them arrived in the latest 12 months.
Which brand do these reports concern?
That cannot be known from the public data. openFDA masks brand and manufacturer names in adverse event records, so the reports counted here cannot be attributed to a particular brand.
What signs are reported most often?
lack of efficacy - NOS (17.5%), deafness (16.5%), vomiting (14.4%), lethargy (10.3%) and diarrhoea (9.3%). These are the coded terms listed in reports; several can appear in one report, and a term's presence is not a finding that the drug was responsible.
Which species and breeds appear in these reports?
dog (93.8%) and cat (6.2%). Among single-breed animals the most frequent labels are Pit Bull, Labrador Retriever, Domestic Shorthair and German Shepherd Dog; popular breeds appear often in any drug's reports because there are more of them.
Are reports rising?
17 reports in the 12 months to March 2026, up 89% from 9 in the 12 months before. FDA posts reports quarterly with a delay of three to six months, so the newest months are incomplete and usually grow in later releases. Counts also move with sales, publicity and time on the market.
Do these reports show that enrofloxacin + ketoconazole + triamcinolone harms pets?
Report counts cannot show that. FDA states that "there is no certainty that the reported drug or device caused the adverse event" and that the event "may have been related to an underlying disease, other drugs used at the same time or other non-drug related sources." FDA also notes that commonly used products may have more reports simply because more animals receive them.
Are these the side effects of enrofloxacin + ketoconazole + triamcinolone?
They are signs listed in reports, not an established list of side effects. The adverse reactions observed in studies are printed on each product's FDA-approved label, which a veterinarian can go through with you. This page is a record of what was reported to FDA.
How do I report a problem with an animal drug?
FDA asks owners and veterinarians to call the drug company first (the number is on the label); companies must pass reports to FDA. Reports can also go directly to FDA on Form FDA 1932a. See the guide on how to report.
Where this comes from. Counts are built from the openFDA Animal & Veterinary adverse event bulk files released 28 Sep 2026, which hold reports FDA's Center for Veterinary Medicine received through 31 Mar 2026. openFDA masks brand and manufacturer names in these files, so drugs are counted by the active ingredients each record discloses and no figure is attributed to a brand, application or company. Ingredient names, and the separate reference lists of approved products, follow the FDA Green Book as of 1 Oct 2026. Drug entries are grouped by the active ingredients their unmasked ingredient field discloses; the application number that records also carry is not used. No report text, lot numbers or reporter details are published. See the methodology and sources; FDA's record is authoritative, and corrections are handled within five working days.
