Combination antiretroviral therapy (cART), which is a lifelong therapy for people living with human immunodeficiency virus, has been associated with nephrotoxicity and hepatotoxicity leading to its discontinuation. This study aimed at investigating the ameliorative potential of naringenin and quercetin on cART-induced hepatotoxicity and nephrotoxicity. Seventy male Wistar rats (225–260 g) were divided into seven groups as control, cART, naringenin, quercetin, dimethyl sulfoxide (DMSO), naringenin/cART (CN) and quercetin/cART (CQ). cART (24 mg/kg), naringenin (50 mg/kg) and quercetin (50 mg/kg) were dissolved in 1% v/v DMSO and administered orally for 56 days. Combination of cART and bioflavonoids had significant increase in superoxide dismutase (P
