Betamethasone Valerate + Gentamicin Sulfate: adverse event reports
All products with this ingredient combination · 8 FDA-approved applications in the Green Book
- Mostly dog reports
- Topical route most often
- Brands masked by FDA
Between March 1987 and October 2025 FDA received 378 adverse event reports listing a drug with the combination betamethasone valerate and gentamicin sulfate as the recorded active ingredients. The Green Book lists 8 FDA-approved applications with exactly this combination.
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, 6 reports named it, close to the 6 of 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 10 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.
Reporters most often listed vomiting (7.9%), lethargy (7.1%) and deafness (6.9%). A report can list several signs, so shares add to more than 100%; 500 different terms appear across these reports. Vomiting appears in 7.9% of these reports, a larger share than in the pooled reports for every drug containing betamethasone valerate (3.7%).
63.2% of reports concern dogs. Not every report describes illness: 24.3% as product or packaging defects. Of reports that state seriousness, 42.3% were classed as serious, and 7.1% 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
2025 covers reports received through March 2026 only.

Top 30 of 500 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

What kind of report it was
Coloured bar: reports naming betamethasone valerate + gentamicin sulfate. 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.

The betamethasone valerate pool is every report naming betamethasone valerate alone or in any combination; this combination accounts for 13.8% 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.

Questions about betamethasone valerate + gentamicin sulfate reports
How many adverse event reports has FDA received for the combination betamethasone valerate and gentamicin sulfate?
378 reports record a drug with the combination betamethasone valerate and gentamicin sulfate as its active ingredients in the openFDA release of 28 Sep 2026, covering reports received through March 2026. 6 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. The Green Book lists 8 approved applications with this combination; the reference list on this page names them without any counts.
What signs are reported most often?
vomiting (7.9%), lethargy (7.1%), deafness (6.9%), lack of efficacy - NOS (5.8%) and diarrhoea (5.6%). 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 (63.2%), cat (10.8%) and human exposure (2.4%). Among single-breed animals the most frequent labels are Domestic, Labrador Retriever, Golden Retriever and Domestic Shorthair; popular breeds appear often in any drug's reports because there are more of them.
Are reports rising?
6 reports in the 12 months to March 2026, close to the 6 of 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 betamethasone valerate + gentamicin sulfate 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 betamethasone valerate + gentamicin sulfate?
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 30 Sep 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.
