In this paper we study the ultraviolet and infrared behavior of the self-energy of a pointlike charge in the vector and scalar Lee-Wick electrodynamics in a d+1 dimensional space time. It is shown that in the vector case, the self-energy is strictly ultraviolet finite up to d=3 spatial dimensions, finite in the renormalized sense for any d odd, infrared divergent for d=2, and ultraviolet divergent for d>2 even. On the other hand, in the scalar case, the self-energy is striclty finite for d\ensuremath≤3, and finite, in the renormalized sense, for any d odd.
