An adverse drug reaction (abbreviated ADR) is an expression that describes harm associated with the use of given medications at a normal dose. The meaning of this expression differs from the meaning of "side effect", as this last expression might also imply that the effects can be beneficial. The study of ADRs is the concern of the field known as pharmacovigilance.

Classification

ADRs may be classified by e.g. cause and severity.

Cause

  • Type A: Augmented pharmacologic effects - dose dependent and predictable
a. intolerance
b.side effects
  • Type B: Bizarre effects (or idiosyncratic) - dose independent and unpredictable
  • Type C: Chronic effects
  • Type D: Delayed effects
  • Type E: End-of-treatment effects
  • Type F: Failure of therapy

Types A and B were proposed in the 1970s, and the other types were proposed subsequently when the first two proved insufficient to classify ADRs.
