52 adverse event reports received by FDA list a drug containing chorionic gonadotropin, alone or in combination, from June 1993 to August 2025. This page pools every ingredient set that includes it; 2 such sets appear in reports.

The Green Book lists 7 FDA-approved applications containing it. openFDA masks brand and manufacturer names in adverse event records, so the reports counted here cannot be attributed to a particular brand.

1 reports arrived in the 12 months to March 2026, with none 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. That is about 2 reports a year over its reporting history and 0% of all reports.

Pooled across every set, the terms listed most often are anaphylaxis (28.8%), death (15.4%) and dyspnoea (13.5%). Many drugs combine several ingredients, and many reports list several drugs, so a term on this page may relate to any of them or to none.

Of reports that state seriousness, 50% were classed as serious (38.6% across the whole database); 17.3% record a death or euthanasia (6.4% overall). Ingredients used in older or sicker animals, or in anaesthesia and cancer care, carry higher shares for that reason alone.

FDA-approved products containing chorionic gonadotropin (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.

Questions about chorionic gonadotropin reports

How many FDA adverse event reports mention chorionic gonadotropin?

52 reports through March 2026, 1 of them in the latest 12 months, counting chorionic gonadotropin alone and in combinations.

Which brands 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 reference list on this page names approved products containing chorionic gonadotropin without any counts.

In which combinations is chorionic gonadotropin reported?

Chorionic Gonadotropin (67.3% of these reports) and Chorionic Gonadotropin + Serum Gonadotropin (32.7% of these reports).

What reactions are reported for chorionic gonadotropin?

anaphylaxis (28.8%), death (15.4%), dyspnoea (13.5%), facial oedema (13.5%) and hyperhidrosis (13.5%). Shares are of reports naming the ingredient; one report can list several terms.

Which animals are these reports about?

horse (44.2%), pig (9.6%) and human exposure (5.8%).

Does a high count mean chorionic gonadotropin is a problem ingredient?

A count 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." Widely used ingredients collect more reports because more animals receive them.

How do I report a problem?

Call the drug company using the number on the label, or send Form FDA 1932a to FDA. 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. Ingredient names follow the Green Book; salts and forms are kept as FDA lists them. Drug entries are matched by the active ingredients their unmasked ingredient field discloses. 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.
