The Veterinary Drugs Directorate classifies an adverse reaction to a veterinary drug as:
The Food and Drugs Act and Regulations require that manufacturers report suspected adverse reactions to new drugs (for regulatory purposes, drugs approved for marketing since 1963, and drugs not yet approved) to the VDD in the Health Products and Food Branch within 15 working days of receipt of such information.
Though there are no regulations requiring veterinary practitioners to report DARs, the Veterinary Drugs Directorate encourages veterinarians to advise us of suspected adverse reactions to any drugs which occur in their practices.
Premarketing clinical trials of a new drug generate data to satisfy the requirements of the Food and Drugs Act and Regulations for animal safety and efficacy, and human safety. The purpose of post marketing surveillance, including DAR reporting, is to continue to monitor the drugs and its effects while in more widespread clinical use.
The more practitioners who report suspected adverse reactions to veterinary drugs, the larger our data base and the more valid our evaluation and appropriate our response.
Reports received by the VDD are discussed, verbally or in writing, with the practitioner and the manufacturer. A summary of reported suspected reactions is published in the Canadian Veterinary Journal. Confidentiality is respected by excluding specific reference to the name of the veterinary practitioner/practice, client, manufacturer and brand name of the drug.
Please report as soon as possible after the occurrence.
Report by telephone, fax or by completing a DAR Report Form (PDF).
Provide as much history and detail as possible, including laboratory and necropsy results.
