Prednisolone: adverse event reports in all combinations
Active ingredient, alone and in combinations
Brand names with this ingredient: Temaril-P, Delta Albaplex, PrednisTab.
The openFDA records give the value "MSK" for the brand name and for the manufacturer name of each drug. FDA says that MSK means "masked". So the site cannot count a report for a brand.
Read this first. FDA says this about the data:
An API dataset query result cannot be used to estimate the risk associated with the product or compare one drug or device product with another. When looking at the results, be aware that there is no certainty that the reported drug or device caused the adverse event. This dataset should not be the sole source of information for clinical decision-making or other assumptions about the safety or effectiveness of a product. The adverse event may have been related to an underlying disease, other drugs used at the same time or other non-drug related sources.

From December 1987 to June 2026, FDA received 5,489 adverse event reports that name a drug with prednisolone, alone or in a combination. 3 sets of active ingredients with prednisolone have a drug page.
Of the 5,489 reports, 4,018 (73.2%) are about dogs. 1,262 reports are about cats (23%). In January to March 2026, FDA received 129 reports that name prednisolone, alone or in a combination. The signs that appear in the largest number of the 5,489 reports are "Lethargy", "Vomiting" and "Lack of efficacy - NOS". A report is not proof that a drug caused a sign.
Reports that name this ingredient fell by 11.5% in the 12 months to June 2026, compared with the 12 months before. Reports for all animal drugs fell by 4.6% in the same periods. The newest months can get more reports in a later update. Reports about cats are 23% of the reports that name this ingredient, and 11% of all reports.

Drug pages with prednisolone
A report names a drug by its set of active ingredients. Each set with prednisolone that has a drug page is in the table, in order of name. The table has 3 sets.
| Active ingredients | Reports, all years | Reports, latest 12 months |
|---|---|---|
| Novobiocin + Prednisolone + Tetracycline | 26 | 0 |
| Prednisolone | 3,368 | 426 |
| Prednisolone + Trimeprazine Tartrate | 2,092 | 44 |
A report can name more than one set, so the counts of the sets can add to more than the count of the page.
An API dataset query result cannot be used to estimate the risk associated with the product or compare one drug or device product with another.

Where the data come from
The counts come from the openFDA Animal and Veterinary adverse event files, export of 30 Oct 2026. The files have the reports that the FDA Center for Veterinary Medicine received through 26 Jun 2026. The files mask brand and manufacturer names. The site counts a drug by the active ingredients that each record gives, and gives no count to a brand, an application or a company. Ingredient names and the lists of approved products follow the FDA Green Book of 2 Nov 2026. Ingredient names follow the Green Book, with salts and forms as FDA lists them.
The site does not publish report text, lot numbers or details of a reporter. FDA's record is the authority. See how the site counts reports, the data sources and the corrections page.
Questions about these reports
- Which brand are these reports about?
The openFDA records give the value "MSK" for the brand name and for the manufacturer name of each drug. FDA says that MSK means "masked". So the site cannot count a report for a brand. The Green Book section of this page lists brand names with this active ingredient.
- Do the reports show that the ingredient caused the signs?
No. A report can name more than one drug, and a drug can have more than one active ingredient. FDA states this about the data.
When looking at the results, be aware that there is no certainty that the reported drug or device caused the adverse event.
The adverse event may have been related to an underlying disease, other drugs used at the same time or other non-drug related sources.
