Abstract: BACKGROUND:Adverse drug reaction signals are reported information on possible causal relationships between an adverse event and a drug. The National Pharmacovigilance Centre (NPC) in Nigeria has over 3,000 reported adverse drug reaction cases which have been adequately entered into the ADR data bank. OBJECTIVE:Data mining of ADR reports from September to November, 2014 were carried out in this present study with the intention to describe the pattern of ADRs and generate possible signals. METHODS:A total of about 100 reported cases with arrays of adverse drug reactions were reported between September and November, 2014 and the data were analyzed using SPSS version 17. RESULTS:Efavirenz/Tenofovir/Lamivudine combination was the highest reported drugs (24.2%) while efavirenz alone was reported in 8 times (8.8%) and HIV (63.3%) was the highest reported indication of drug use. Efavirenz caused central nervous system adverse reactions as revealed in the ADRs analyses. Zidovudine/Lamivudine/Nevirapine combination in concomitant use with Cotrimoxazole were reported 8 times with generalized maculopapular rashes on the trunk with some area of hyper pigmentation with intense itching documented twice and big/swollen rashes all over the faces. Zidovudine was also reported four times to cause severe anaemia. CONCLUSION:More surveillance is advocated so as to ascertain the consistency of the observed ADRs and thereafter establish appropriate signals.
