Serious Adverse Reaction [SAR]

« Back to Glossary Index

An adverse drug reaction (ADR) is called serious if at any dose it:

  • results in death,
  • is life-threatening (at risk of death at the time of the adverse event, not an event which ‘could’ hypothetically have caused death if it were more severe),
  • requires hospitalisation or extension of existing inpatients’ hospitalisation,
  • results in a persistent or significant disability or incapacity, or
  • is a congenital anomaly or birth defect.
