The primary hypothesis is that continuous administration of an OCP (CCOCP regimen) will result in more pain relief than a traditional 21/7 administration in primary dysmenorrhea (PD) patients.

Primary Outcome Measures:
  • The primary outcome will be the difference in subjective perception of pain as measured by the Visual Analog Scale over the period of six months. [ Time Frame: 6 months ] [ Designated as safety issue: No ]

Enrollment: 38
Study Start Date: August 2007
Study Completion Date: April 2011
Primary Completion Date: March 2011 (Final data collection date for primary outcome measure)
Intervention Details:
    Drug: Monophasic oral gestodene/ethinyl estradiol
    Monophasic oral gestodene/ethinyl estradiol
    Other Name: Oral contraceptives
Detailed Description:

It is well established that excess prostaglandin production in primary dysmenorrhea (PD) leads to ischemia of the uterine muscle, which consequently causes pelvic pain. A large number of drugs have been studied for pain relief in dysmenorrhea patients with non-steroid anti-inflammatory drugs (NSAIDs) being the most effective with the overall success rate of more than 75%. Oral contraceptive pills (OCP) are also an established treatment for PD with the success rate of 70%. Lately, OCP's have been used continuously in patients with endometriosis and had better pain control than traditional administration of OCP.


Ages Eligible for Study:   18 Years to 35 Years
Genders Eligible for Study:   Female
Accepts Healthy Volunteers:   Yes

Inclusion Criteria:

  • Healthy women ages 18-35 with a history of PD (onset < 3 years after menarche).
  • Subjects must have had regular (25-31 day) menstrual cycles for the three month period preceding enrollment, with symptoms of moderate to severe PD during those cycles.

Exclusion Criteria:

  • Patients who have contraindications to OCP therapy.
  • Known or suspected secondary dysmenorrhea (major abdominal or pelvic surgery, endometriosis, pelvic inflammatory disease (PID), ovarian cysts, pathological vaginal secretion, chronic abdominal pain, inflammatory bowel disease, irritable bowel syndrome).
  • Concomitant treatment with oral contraceptives, GnRH agonists and antagonists, antiandrogens, gonadotropins, anti-obesity drugs.
  • The use of contraceptive implants, injectable contraceptives or intrauterine devices. The washout period on all these medications will be 3 months.
  • Migraines, depression requiring hospitalization or associated with suicidal ideation during previous estrogen or ocp use.
  • Known or suspected hypersensitivity to trial drug.
  • Patients enrolled simultaneously into other investigative studies that require meds.
