We investigate the Casimir-Polder interaction between two atoms one of which is excited. We show that the perturbation theory results in divergence of integrals for the interaction between an excited atom and a media of dilute gas. We considered the interaction between two atoms embedded in a dielectric medium. The non-perturbative method used in this paper shows that the interaction between the atoms is suppressed due to absorption of photons by the medium. Now the integrals are divergent no more. Interaction between two media of dilute gases is considered for the case of high temperatures.
