We present results for the $\eta_c$-nucleus bound state energies for various nuclei using
an effective Lagrangians approach. The attractive potentials for the $\eta_c$ in the nuclear medium
originate from the medium-modified intermediate $D D^{*}$ state in the $\eta_c$ self energy,
using the local density approximation. Our results suggest that the $\eta_c$ should form bound states with all the nuclei considered.
