The reporting of suspected serious adverse drug reactions (ADRs) to government regulators of the pharmaceutical industry by consumers (parents, guardians or caregivers) is key to identifying drug safety issues and improving prescription drug safety.

Health Canada defines a serious ADR as a noxious and unintended response to a drug that occurs at any dose and that:

  • Results in death.
