Fluctuation-induced interaction was studied in confined fluids above the isotropic-lamellar transition. The Casimir force had a long-range tail proportional to 1/d, where d was the interwall distance, at the ideally continuous transition which was due to the two-dimensional distribution of bulk soft modes in the q space. A strong Casimir force with a range of several lamella thickness was realistic above the transition. An oscillatory force profile was also found near a surface-induced transition.
