ICSR (Individual Case Safety Report) in Pharmacovigilance
An Individual Case Safety Report (ICSR) is a structured and detailed report that documents an adverse drug reaction (ADR) or any suspected safety issue observed in a single patient. ICSRs are a key part of pharmacovigilance and help in continuous monitoring of a medicine’s safety throughout its lifecycle. These reports are submitted by healthcare professionals, patients, or marketing authorization holders to regulatory authorities for evaluation and signal detection.
Concomitant medications: other drugs taken along with the suspected drug
Medical history: relevant conditions and risk factors
Outcome: recovered, recovering, not recovered, fatal, unknown
Reporter information: healthcare professional or consumer report
Causality assessment: possible, probable, or unlikely relationship with the drug
Importance of ICSR
ICSRs support early detection of safety signals, improve risk management, and strengthen patient safety. They also contribute to regulatory actions such as label updates, safety warnings, restricted use, or product withdrawal when necessary.
ICSRs are the foundation of real-world drug safety monitoring and play a major role in protecting public health.
