We investigate the implications of the four-nucleon terms in the chiral effective Lagrangian for the s-wave K-nucleon effective interaction. We find that such terms play a non-trivial role in the description of symmetric nuclear matter. Our results for the kaon effective energy and in-medium -nucleon scattering are in agreement with the previous prediction obtained by in-medium scaling qualitatively.
