NSAIDs as First-Line Treatment for Dysmenorrhea

Evidence Supporting NSAID Efficacy

  • The American College of Obstetricians and Gynecologists recommends NSAIDs, such as Indomethacin, Mefenamic acid, and Flufenamic acid, for the treatment of dysmenorrhea, as they have been shown to be effective in reducing menstrual blood loss and pain compared to placebo 1
  • Clinical trials have demonstrated that NSAIDs can significantly reduce menstrual blood loss and pain compared to placebo, with an odds ratio of 7.91 (95% CI 5.65 to 11.09) 1

Treatment Recommendations

  • The Centers for Disease Control and Prevention recommends short-term treatment (5-7 days) with NSAIDs, which is typically sufficient for symptom management 2, 1

Potential Adverse Effects and Precautions

  • The American Heart Association recommends that NSAIDs be used with caution in patients with cardiovascular disease 4
  • The National Comprehensive Cancer Network recommends that NSAIDs be used with caution in patients with a history of peptic ulcer disease, advanced age (>60 years), or concurrent corticosteroid therapy 3
  • Naproxen and ibuprofen are preferred NSAIDs for individuals at high risk for cardiac toxicities, according to the National Comprehensive Cancer Network 3
