The manifestation of the higher-order effects induced by the flavor-changing neutral currents in {ital B} decays is analyzed in the left-right-symmetric generalization of the electroweak unification. In such left-right models the effects of the right-handed currents and the mixing between the two gauge bosons give rise to some enhancement relative to the standard model in the branching ratio of the rare processes {ital b}{r arrow}{ital s}{gamma}, {ital b}{r arrow}{ital sg}, {ital b}{r arrow}{ital sl}{sup +}l{sup {minus}}, and {ital b}{r arrow}{ital s}{nu}{bar {nu}}, in particular if the present bounds on the {ital W}{sub {ital R}} mass and on the mixing {xi} turn out to be too severe. We can conclude that this kind of rare {ital B} physics can put interesting constraints on these models.
