Propofol: adverse event reports
All products with this active ingredient · 4 FDA-approved applications in the Green Book
- Mostly dog reports
- Intravenous route most often
- Brands masked by FDA
Between March 1997 and March 2026 FDA received 4,760 adverse event reports listing a drug with propofol as the recorded active ingredient. The Green Book lists 4 FDA-approved applications with this single active ingredient.
openFDA masks the brand and manufacturer in every report, so these figures describe the ingredient across all products and cannot be attributed to a brand.
In the 12 months to March 2026, 502 reports named it, down 13% from 578 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. Over its whole reporting history that is about 164 reports a year and 0.4% of all 1,357,245 reports (0.3% 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 most frequently coded terms are death (13.1%), lethargy (8.2%) and cardiac arrest (7.6%). A report can list several signs, so shares add to more than 100%; 1,418 different terms appear across these reports.
62.9% of reports concern dogs. Not every report describes illness: 13% as product or packaging defects. Of reports that state seriousness, 65.7% were classed as serious, and 18.8% 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 1,418 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 propofol. 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.

Route of administration stated in reports: intravenous (3,073), parenteral (65), other (23), subcutaneous (19), intramuscular (6), respiratory (inhalation) (3).
In context

|---|---|---|---|
| Reports | 4,760 | 985,675 | 1,357,245 |
| Share of that pool's reports naming this drug | — | 0.3% | 0.4% |

This set accounts for 99.5% of all reports naming propofol, so no separate ingredient column is shown. 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.
FDA-approved products containing propofol (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.
| Trade name | Active ingredients | Sponsor | Approved for | Application |
|---|---|---|---|---|
| Rapanofal | Propofol | IVAOES, INC. DBA IVAOES ANIMAL HEALTH | Dogs, Cats | NADA 141-070 |
| PropoFlo; PropoFlo 28 | Propofol | Zoetis Inc. | Dogs | NADA 141-098 |

| PropofolVet Multidose | Propofol | Parnell Technologies Pty. Ltd. | Dogs | ANADA 200-793 |
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 propofol reports
How many adverse event reports has FDA received for propofol?
4,760 reports record a drug with propofol as its active ingredient in the openFDA release of 28 Sep 2026, covering reports received through March 2026. 502 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 4 approved applications with this ingredient alone; the reference list on this page names them without any counts.
What signs are reported most often?
death (13.1%), lethargy (8.2%), cardiac arrest (7.6%), bradycardia (7.4%) and color, Abnormal (7.3%). 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 (62.9%), cat (23.9%) and other (0.5%). Among single-breed animals the most frequent labels are Domestic Shorthair, Labrador Retriever, Domestic and Chihuahua; popular breeds appear often in any drug's reports because there are more of them.
Are reports rising?
502 reports in the 12 months to March 2026, down 13% from 578 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 propofol 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 propofol?
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.
