In this work, we examine the constraints imposed on the doublet left-right symmetric model (DLRSM) by analyzing Higgs data from LHC. Specifically, we investigate the key parameters of the model, denoted as the ratios $r=\\kappa_2/\\kappa_1$ and $w=v_L/\\kappa_1$. While previous research assumed these ratios to be very small, we find that there is no lower bound on either $r$ or $w$ and the upper bound is set by the perturbative requirement of Yukawa couplings . Notably, the Yukawa coupling of the bottom quark to the lightest CP-even scalar not only discourages the selection of small $r$ values but also implies a preference for $w$ values approximately around $O(1)$. These values are also favored by the indirect constraint on the mass of heavy CP-even scalars.
