We constrain the new physics parameter space using the branching ratio of the rare decay mode $D^0 \\to \\mu^+ \\mu^-$ and the $D^0-\\bar D^0$ oscillation data. We compute the branching ratios, forward-backward asymmetry parameters and flat terms in $D^{+(0)} \\to \\pi^{+(0)} \\mu^+ \\mu^-$ processes using the constrained parameters.
