ADR monitoring helps in detecting the occurrence of rare and unknown ADRs and helps in prevention of further occurrence. Several methods are adopted for effective monitoring of ADRs. An effective ADR monitoring program requires adequate infrastructure and trained manpower. In developed countries, the ADR monitoring system is well established.
