The scope of this paper is to assess the performance of the Brazilian Notification System for Health Surveillance, with respect to the registration of information on adverse drug-related effects on health (Notivisa/medication) based on previously selected attributes.  In the study period, 63,512 registrations were identified in Notivisa/medication, the majority being considered severe (60.5%).  The performance of Notivisa/medication was considered satisfactory with respect to two of the eight attributes (validity and positive predictive error) and deficient in six of the remaining attributes (simplicity, acceptability, representativeness, completeness, consistency and timeliness).
