• Experiencing dysmenorrhea symptoms that are effects of or thought to be effects of (at least in part) secondary causes of dysmenorrhea, such as uterine fibroids, endometriosis, and/or currently symptomatic ovarian cysts.
• Experienced dysmenorrhea that did not require, in the opinion of the subject, the use of analgesic medication during four of the previous six menstrual episodes.
• Has dysmenorrhea refractory to treatment with commonly used analgesic medications for the treatment of menstrual pain (e.g., ibuprofen or naproxen sodium).

• A history of past or ongoing clinically significant disease, illness, or disorder that, in the opinion of the Investigator, makes the subject unsuitable for study participation including active vaginal, vulvar, and cervical lesions.
• Laboratory abnormalities that, in the opinion of the Investigator, could contraindicate study participation such as liver function tests > 1.5 times the upper limit of normal (At the Investigator's discretion, laboratory tests may be repeated once for verification.)
• A history of, within the past 4 years, or ongoing significant psychiatric illness that, in the opinion of the Investigator, makes the subject unsuitable for study participation.
• A history of chronic analgesic or tranquilizer use or drug abuse including alcohol within the 6 months before providing consent for this study.
