  We revisited excited leptons ($\bar{l^*}l$) production through gauge
mediation only at LHC, followed by their two body decays into Standard Model
(SM) particles. We include the next-to-leading order (NLO) QCD corrections to
these processes. We have shown that these corrections can be substantial and
significant. We also show that the scale dependence of the NLO cross section is
greatly reduced as compare to leading order (LO) cross section.
