Efficacy of ketoprofen in treating primary dysmenorrhea

A 6-month double-blind crossover trial compared ketoprofen with placebo in the treatment of primary dysmenorrhea in 27 women who satisfied explicit inclusion and exclusion criteria. The response to treatment was assessed with a pain scale and a disability scale and by noting amelioration of associated symptoms, such as nausea, vomiting, diarrhea, fatigue, dizziness and headache. Ketoprofen was significantly superior to placebo in relieving the pain (p less than 0.001), disability (p less than 0.001) and headache (p less than 0.01) associated with menstruation. No order effect of treatment was observed. Adverse effects were few and minimal.
