Antimalarial drug resistance remains a critical threat to global malaria control, with profound implications for public health and economic stability in endemic regions such as Nigeria. Resistance to first-line antimalarial, compromises efforts to reduce malaria-related morbidity and mortality. Nigeria, bearing one of the highest global malaria burdens, faces significant challenges as resistance exacerbates healthcare costs and strains limited resources. This paper examines the threat posed by antimalarial drug resistance in Nigeria and beyond, including its impact on treatment efficacy, increased disease burden, and long-term economic consequences. Higher treatment costs, prolonged illness, and reduced productivity, the socio-economic toll on communities is substantial. Therefore there is need to strengthened surveillance systems, effective drug policies, and investment in research and development of novel antimalarial and also vaccines.
