What is a Side Effect?

Side effects are troublesome symptoms or feelings that occur when taking a health product. Side effects can range from minor irritations, such as a skin rash, to serious and life-threatening reactions, such as a heart attack of liver damage. A side effect can also be when a product has no effect or has not performed the intended treatment. They can occur within minutes after taking a medicine, or can take years to develop.

Side effects are troublesome symptoms or feelings that you may not expect that show up when you are taking a medicine. Side effects are sometimes also called adverse reactions, especially by doctors and other health professionals.

What types of Side Effects should be reported?

All suspected side effects should be reported, especially those that are:

  • Unexpected, regardless of their severity, i.e., not consistent with product information or labelling; or
  • Serious, whether expected or not, i.e., that requires being admitted to the hospital, lengthened hospital stay, causes a birth defect, disability, is life-threatening or results in death;
  • Reactions to recently marketed health products (on the market for less than five years), regardless of their nature or severity.
