  • The number of days of dysmenorrheic pain per cycle at the end of a 3-cycle follow-up period compared with baseline [ Time Frame: 9 months ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Average daily dysmenorrheic pain VAS score in each cycle [ Time Frame: 9 months ] [ Designated as safety issue: No ]
  • Rescue medication consumption in each cycle [ Time Frame: 9 months ] [ Designated as safety issue: No ]
  • Accompanying symptoms in each cycle [ Time Frame: 9 months ] [ Designated as safety issue: No ]
