Definition of an adverse experience

The following definition of an adverse experience is to be used by product registration holders when determining what information should be submitted to us. An adverse experience is:

An unintended or unexpected effect on animals, human beings or the environment, or lack of efficacy associated with the use of a registered veterinary chemical product when used according to label instructions.

Definition of a serious adverse experience

A serious adverse experience involving veterinary medicines is expected to be reported to the APVMA by the product registration holders as soon as the registration holder becomes aware of the information. A serious adverse experience is:

Any adverse experience that results in death, is life-threatening, results in persistent or significant disability or incapacity, prolonged duration of serious signs or is a congenital abnormality or birth defect in animals. A serious adverse experience in humans is one that requires medical treatment or involves death.

If there is any doubt about the seriousness of a suspected adverse experience, the incident must be treated as a serious adverse experience and reported by the registration holder to the APVMA as soon as possible.
