Questions about August 2014

How many animal drug adverse event reports did FDA receive in August 2014?

6,823 reports are in the openFDA release of 28 Sep 2026. The same month a year earlier has 6,509.

Which drugs were named most often?

By active ingredient: milbemycin oxime + spinosad (2,175), spinosad (873), ivermectin + pyrantel pamoate (725), afoxolaner (370) and selamectin (267). Brands are masked in the public data.

Which signs were listed most often?

emesis (1,573), lethargy (909), lack of efficacy - NOS (900), vomiting (842) and lack of efficacy (ectoparasite) - flea (511).

Can the count for a month still change?

Yes. FDA posts reports quarterly with a delay of three to six months, so the newest months are incomplete and usually grow in later releases. Older months change little.

Does a busy month mean something went wrong that month?

Not by itself. The date is when FDA received the report, not when the event happened, and volume follows season, product launches and publicity. 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."

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. The month is the date FDA first received the report, not the date of the event. 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.
