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.
