Treatment for Dyspareunia in a 52-Year-Old Postmenopausal Woman

Low-dose intravaginal estrogen therapy is the recommended first-line treatment for postmenopausal women with dyspareunia due to vulvovaginal atrophy. 1

Understanding Postmenopausal Dyspareunia

Dyspareunia in postmenopausal women is commonly caused by genitourinary syndrome of menopause (GSM), characterized by:

• Vaginal dryness
• Decreased lubrication
• Thinning of vaginal tissues
• Increased vaginal pH
• Decreased elasticity

Treatment Algorithm

First-Line Treatment Options:

1. Vaginal Estrogen Therapy:

   • Available in several forms:
     • Vaginal creams
     • Vaginal tablets/inserts
     • Vaginal rings
   • Apply according to product instructions:
     • Daily for 1-2 weeks initially
     • Then 2-3 times weekly for maintenance 1
   • Low-dose formulations (such as 0.003% estradiol vaginal cream) are effective with minimal systemic absorption 2

2. Ospemifene (Oral Option):

   • 60 mg tablet taken with food once daily 3
   • FDA-approved for moderate to severe dyspareunia due to menopause 3, 4
   • Consider for women who prefer oral medication
   • Important cautions:
     • Contraindicated in women with:
       • Undiagnosed abnormal genital bleeding
       • Known/suspected estrogen-dependent neoplasia
       • Active or history of DVT/PE
       • Active arterial thromboembolic disease 3

Alternative Non-Hormonal Options:

For women with contraindications to estrogen therapy:

1. Vaginal Moisturizers:

   • Apply 2-3 times weekly on an ongoing basis 1

2. Water-Based Lubricants:

   • Use during all sexual activity 1

3. Pelvic Floor Physical Therapy:

   • Particularly helpful for women with concurrent pelvic floor dysfunction 1

4. Other Options:

   • Topical vitamins (D or E) for vaginal discomfort 1
   • CO₂ laser therapy when other options have failed 1

Clinical Considerations

Monitoring and Follow-up:

• Regular follow-up to assess symptom improvement
• Monitor for abnormal vaginal bleeding, which warrants further investigation
• Annual clinical review to assess ongoing need and compliance 1

Important Contraindications for Estrogen Therapy:

• Low-grade serous epithelial ovarian cancer
• Granulosa cell tumors
• Certain types of sarcoma
• Advanced endometrioid uterine adenocarcinoma
• Active thromboembolic disorders 1

Benefits of Treatment:

• Improved vaginal health and sexual function
• Decreased pH (returning to premenopausal levels)
• Improved vaginal cytology (increased superficial cells, decreased parabasal cells) 2
• Enhanced quality of life

Common Pitfalls to Avoid:

1. Failure to diagnose: Many women don't discuss dyspareunia with healthcare providers; direct questioning is essential 5
2. Inadequate treatment duration: Vaginal estrogen therapy requires consistent use for optimal effect
3. Overlooking contraindications: Carefully screen for conditions where estrogen therapy is contraindicated
4. Neglecting follow-up: Regular assessment is needed to ensure symptom improvement and monitor for adverse effects

Special Considerations

• For women with hypertension, transdermal estradiol is the preferred delivery method 1
• Local vaginal estrogen therapies have minimal systemic absorption compared to systemic hormone therapy 1
• Use the lowest effective dose of topical vaginal estrogen 1

Vaginal estrogen therapy has been shown to effectively treat dyspareunia in postmenopausal women with significant improvements in symptoms and objective measures of vaginal health 2, 6.
