Dysmenorrhea, a Narrative Review of Therapeutic Options

Abstract

Dysmenorrhea is the most common pathology women of childbearing age face. It is defined as painful uterine cramping associated with menstruation. Primary dysmenorrhea occurs in the absence of an organic cause, whereas secondary dysmenorrhea is pelvic pain associated with an underlying pelvic pathology. The purpose of this review is to discuss the pathophysiology of dysmenorrhea and provide a discussion of pharmacologic and non-pharmacologic treatment options. Prostaglandins play a large role in the pathophysiology of dysmenorrhea by causing myometrial contraction and vasoconstriction. The first-line treatment for dysmenorrhea is with nonsteroidal anti-inflammatory drugs due to the inhibition of cyclooxygenase enzymes, thereby blocking prostaglandin formation, as well as hormonal contraception. Other pharmacologic treatment options include Paracetamol, as well as Gonadotrophic Release Hormone Analogs, which are typically used in the treatment for endometriosis. Non-pharmacologic treatments with strong evidence include heat therapy and physical exercise. There are less evidence-based data behind other modalities for treating dysmenorrhea, such as dietary supplements, acupuncture, and transcutaneous nerve stimulation, and these methods should be used in conjunction with first-line therapy after a discussion of risks and benefits. Lastly, for women who fail medical management, surgical options include endometrial ablation, presacral neurectomy, and laparoscopic uterosacral nerve ablation. Further research is needed to measure the socioeconomic burden of dysmenorrhea on the healthcare system and to evaluate the efficacy of treatment combinations, as a multi-modal approach likely provides the most benefit for women who suffer from this condition.
