Then the equilibrium will shift towards the reactant side........

Explanation:

For #A+BrightleftharpoonsC+D#, if more product is added, the equilibrium will move so as to offset the external perturbation, and move to the left as written. This is a restatement of Le Chatelier's principle: a system at equilibrium when subject to an external perturbation will move so as to offset the external perturbation (and again note that #"offset"!="counteract"#).
