Follicle Stimulating Hormone (Super-Ov): adverse event reports that FDA received
Active ingredient
The name in brackets is a brand name with this active ingredient.
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.

Contacting a veterinarianHow to report to FDAFrom May 1994 to January 2025, FDA received 50 adverse event reports that name a drug with follicle stimulating hormone as its active ingredient. Of the 50 reports, 47 (94%) are about cattle. 1 report is about goats (2%).
In January to March 2026, FDA received no reports that name this drug. The sign that appears in the largest number of the 50 reports is "Ineffective, superovulation". A report is not proof that a drug caused a sign.
Fewer than 20 reports named this drug in the 12 months before June 2026, so this page gives no change. Reports about cattle are 94% of the reports that name this drug, and 2.3% of all reports.
Search engines list a drug page with 500 reports or more in all years. The page also needs 30 reports or more in the 12 months to June 2026. This page is under one of these numbers. The site keeps the page and keeps it out of search engines.

January to March 2026 is the latest closed quarter in the data. In that quarter FDA received 0 reports that name follicle stimulating hormone: 0 dog, 0 cat, 0 horse, 0 other or not given.

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. The site does not use the application number that a record has.
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.
