How to differentiate between an AE, ADR, SE and an allergy reaction?

Adverse event (AE)

  • defined as an unexpected reaction that may be present during treatment with a pharmaceutical product; not necessarily is associated as a cause of this treatment.
  • Example: an elderly patient falls due to the sedating drug he is taking.

Adverse drug reaction (ADR)

  • happens when a patient using a pharmaceutical product at a normal dose for prophylaxis, diagnosis, treatment or for the modification of physiological function encounters an unintended, noxious response.
  • All ADRs are harmful and can be assumed as AE but not vice versa.

Side Effects

  • an unintended response related to the pharmacological properties of the drug; of helpful or harmful in nature when a patient using a pharmaceutical product at a normal dose for prophylaxis, diagnosis, treatment or for the modification of physiological function

Allergy Reaction

  • the body equips itself with an immunological response to a 'foreign' or perceived foreign materials.
  • Allergic reactions can be included as an ADR but not all ADRs can be said to be allergic reactions.
