By means of an effective-Hamiltonian method we reconsider the derivation of the effective interaction in a fermion-antifermion system. Furthermore, we point out some errors of Gara and co-workers in their treatment of fermion-antifermion bound states by solving the reduced Salpeter equation in configuration space.
