Rathna was released on 7 May 1998. Ji of Kalki felt the first half moves smoothly because the scenes ends quickly however the latter half is dragged. He praised Vadivelu's humour and Sangeetha's acting but felt Revathi was underutilised. D. S. Ramanujam of The Hindu wrote that the film's premise "has not been cogently presented by new director, K. Ilanchezhian. The main reason is that he could not fully accommodate the large cast. Seasoned artistes like Revathi suffer in the process". He added, "The old fashioned way of presenting the twins appearing together has not been improved upon by the director nor is it the fault of Murali, handling both roles with painstaking sincerity".
