Celecoxib versus mefenamic acid in the treatment of primary dysmenorrhea.

Background The objective was to compare the effectiveness and tolerability of mefenamic acid and celecoxib in women with primary dysmenorrhea (PD) and to compare the quality of life of study participants pre- and post-treatment. Materials and methods This was a randomized crossover clinical trial conducted among sexually inactive female adults aged 18-25 years with PD. Participants were asked to rate their pain score and answer a validated quality of life questionnaire (EQ-5D-3L) before and after consumption of each medication in two menstrual cycles. The effectiveness of celecoxib and mefenamic acid in treating PD was compared with regard to reduction in pain score and the need for medical leave and rescue therapy. Drug tolerability was determined by comparing the occurrence of side effects of both drugs. Quality of life scores pre- and post-intervention were measured and compared. Results Mefenamic acid had a comparable effect to celecoxib in relieving symptoms of PD. Both drugs were equally tolerable and showed similar impacts on quality of life. Conclusions This study demonstrated that mefenamic acid and celecoxib had similar effectiveness in improving pain score and quality of life in women with PD.
