Animal & Veterinary
Adverse Drug Experience (ADE) Reports
The Cumulative Adverse Drug Event (ADE) Summaries Report listed on the website contains ADE data from reports received on paper between 1987 and April 30, 2013. CVM has transitioned to electronic reporting and is actively working to improve this website by developing a cumulative summary report which will include ADE data from the reports received electronically. During this transition period, the cumulative summaries for the paper reports received through April 2013 will be maintained. However, currently, the electronically reported ADE data is not contained in this website report. If you wish to be notified of updates to the Summaries report, you may subscribe to our email updates. We thank you for your patience during this transition period.
Cumulative Veterinary ADE Reports
1987 to April 30, 2013
In the spirit of openness and transparency, the Center for Veterinary Medicine (CVM) has created and posted these ADE summary reports for the public. CVM has posted the Cumulative ADE Summaries Report so that veterinarians and animal owners can have easily available access to information about signs that have been associated with drugs. These reports will be updated on a monthly basis. This summary report does not include electronic submissions. We are currently developing this capability and will include electronic submissions at some point in the future.
The primary purpose for maintaining the CVM ADE database is to provide an early warning or signaling system to CVM for adverse effects not detected during pre-market testing of FDA-approved animal drugs and for monitoring the performance of drugs not approved for use in animals. Information from these ADE reports is coded and entered into a computerized FDA/CVM ADE database. CVM scientists use the ADE database to make decisions about product safety which may include changes to the label or other regulatory action.
The Center's adverse drug experience (ADE) process takes into consideration confounding factors such as:
- Concomitant drug use
- The medical and physical condition of animals at the time of treatment
- Environmental and management information
- Product defects
However, the specifics of these complex factors cannot be addressed in these reports.
The CVM ADE reporting system depends on detection of adverse clinical events by veterinarians and animal owners. For information on ADE reporting, see Veterinary Adverse Event Voluntary Reporting.
Search for the active ingredient of a drug to see if particular signs have been reported with its use. These signs are listed in order from most frequently observed to least frequently observed. It is important to remember that the report cannot be used to estimate drug risk or compare one drug with another. When looking at the report, the reader should be aware that:
- For any given ADE report, there is no certainty that the reported drug caused the adverse event. The adverse event may have been related to an underlying disease, using other drugs at the same time, or other non-drug related causes. And, this listing does not include information about underlying diseases, other drugs used at the same time, other non-drug related causes, or the final outcome of the reaction.
- The accuracy of information regarding the ADE is dependent on the quality of information received from the veterinarian or animal owner.
- Accumulated ADE reports should not be used to calculate incidence rates or estimates of drug risk, because there is no accurate way to determine how many animals were given the drug. For example, if a drug is widely used to treat certain conditions, there may be more ADEs for that drug than another product that is not used as often. This would not mean that the first drug was more unsafe than the second. The number of reports simply represents the numbers of ADEs received for a particular drug, by species, and route of administration.
- Information on how the drugs were used (for indications on the product label or in an extra label manner) is not provided.
- Adverse experiences are listed by the active ingredient of each drug in the ADE Report. One of the active ingredients in the list may represent more than one brand name. Interested individuals can find a complete list of brand names associated with each active ingredient by using Animal Drugs @ FDA and selecting Section 2: Active Ingredients.
