Tylosin Tartrate: adverse event reports in all combinations
Active ingredient, alone and in combinations
Brand names with this ingredient: Tylan, Component, BiloVet, Tylovet.
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 March 2004 to May 2026, FDA received 630 adverse event reports that name a drug with tylosin tartrate, alone or in a combination. 3 sets of active ingredients with tylosin tartrate have a drug page.
Of the 630 reports, 340 (54%) are about dogs. 99 reports are about cattle (15.7%). In January to March 2026, FDA received 12 reports that name tylosin tartrate, alone or in a combination. The signs that appear in the largest number of the 630 reports are "Death", "Lack of efficacy - NOS" and "Diarrhoea". A report is not proof that a drug caused a sign.
Reports that name this ingredient rose by 17.1% 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 dogs are 54% of the reports that name this ingredient, and 72.6% of all reports.

Drug pages with tylosin tartrate
A report names a drug by its set of active ingredients. Each set with tylosin tartrate 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 |
|---|---|---|
| Estradiol + Trenbolone Acetate + Tylosin Tartrate | 32 | 5 |
| Estradiol + Tylosin Tartrate | 74 | 0 |
| Tylosin Tartrate | 521 | 34 |
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.
