Vaginal DHEA: What Prasterone Does for Menopausal Dryness

Vaginal dryness is a common symptom of menopause, affecting up to 50% of postmenopausal women. As estrogen levels drop, the tissues of the vulva and vagina can become thinner, less elastic, and less lubricated. This change often leads to discomfort, itching, burning, and pain during intercourse (dyspareunia). One effective, FDA-approved option for local treatment is prasterone, also known as vaginal DHEA. Below, we explain what prasterone is, how it works, its benefits, safety considerations, and practical tips for use.

What Is Vaginal DHEA (Prasterone)?

• Chemical name: Dehydroepiandrosterone (DHEA), a natural hormone produced by adrenal glands.
• Approved form: Prasterone (brand name Intrarosa®) is a 6.5 mg intravaginal ovule.
• Approval: FDA-approved in 2016 to treat moderate-to-severe dyspareunia due to menopause.
• Delivery: Inserted once daily at bedtime, allowing slow release of DHEA directly into vaginal tissue.

How Prasterone Works

Prasterone is a precursor hormone. Once it enters vaginal cells, enzymes convert DHEA into:

• Estrogens (estradiol, estrone)
• Androgens (testosterone, dihydrotestosterone)

This local conversion:

1. Restores cell health
   • Increases maturation of vaginal lining cells (improves the “maturation index”).
2. Improves lubrication
   • Boosts natural moisture production.
3. Normalizes pH
   • Helps keep vaginal pH in the slightly acidic range (around 4.0–4.5), discouraging bacterial overgrowth.
4. Enhances elasticity
   • Strengthens connective tissue, reducing fragility and microtears.

Because prasterone acts locally with minimal systemic hormone changes, it targets menopausal dryness without large increases in blood estrogen levels.

Benefits of Vaginal DHEA

Clinical trials and real-world experience show that prasterone can:

• Alleviate vaginal dryness, itching, and burning
• Reduce pain during intercourse (dyspareunia)
• Improve vaginal cell quality (higher maturation index)
• Restore healthy pH balance
• Enhance vaginal elasticity and thickness
• Offer long-term relief when used daily for at least 12 weeks

Key study outcomes:

• 75% of women reported reduced pain with sex after 12 weeks
• Significant improvements in vaginal lining health and pH by week 8
• Effects sustained with continued use

Who Can Benefit?

Prasterone is intended for:

• Postmenopausal women experiencing moderate to severe vaginal dryness or pain with intercourse
• Those who prefer a local treatment rather than oral or transdermal hormone therapy
• Women without contraindications to estrogen or androgen precursors

It is not suitable for women with:

• Undiagnosed vaginal bleeding
• Known or suspected estrogen- or androgen-dependent cancers
• Severe liver disease or uncontrolled endocrine disorders

Always review your medical history with a healthcare provider before starting.

How to Use Prasterone Safely

1. Insert one 6.5 mg ovule
   • Best done at bedtime to allow the ovule to melt and release DHEA overnight.
2. Clean hands and applicator
   • Wash hands thoroughly and use the single-use applicator included in each pack.
3. Daily routine
   • Use once daily for at least 12 weeks to judge effectiveness. After initial benefit, continue daily or as directed by your doctor.

Tips for success:

• Avoid using a tampon or intercourse immediately after insertion.
• If you miss a dose, insert as soon as remembered—do not double up.
• Store at room temperature and keep the ovules in their blister pack until use.

Expected Timeline of Improvement

• Weeks 1–4: May notice mild relief in dryness; cell changes begin.
• Weeks 4–8: Clear improvements in vaginal lubrication and pH balance.
• Weeks 8–12: Reduction in pain with sex, improved tissue health.
• Beyond 12 weeks: Maintain daily use to sustain benefits.

If you don’t experience relief by 12 weeks, discuss alternative options with your healthcare provider.

Safety and Side Effects

Prasterone is generally well tolerated. Most side effects are mild and localized:

• Vaginal discharge
• Mild vaginal itching or irritation
• Changes in libido (rare)

Because systemic absorption of DHEA is minimal, risks associated with oral hormone therapies—such as blood clots or significant breast tenderness—are very low. However, monitor for:

• Unexpected vaginal bleeding
• Worsening pain or irritation
• Any new or unusual symptoms

---

Precautions and Contraindications

Do not use vaginal DHEA if you have:

• Undiagnosed abnormal vaginal bleeding
• Active or past estrogen-sensitive cancer (e.g., breast, endometrial)
• Known hypersensitivity to DHEA or any ingredient in the ovule

Discuss with your doctor if you have:

• A history of thromboembolic disorders
• Liver disease or uncontrolled endocrine conditions
• Severe pelvic organ prolapse

When to Seek Medical Advice

While prasterone addresses menopausal vaginal dryness effectively, certain signs warrant prompt medical attention:

• Heavy or continuous vaginal bleeding
• Severe pelvic pain or fever
• Signs of infection (foul odor, greenish discharge)
• New lumps or breast changes

If you experience life-threatening or serious symptoms, please speak to a doctor or visit your nearest emergency department immediately.

Integrating Prasterone into Your Menopause Care

Menopausal changes affect more than just your reproductive system. A comprehensive approach can include:

• Lifestyle measures: Regular sexual activity or use of lubricants/moisturizers to maintain tissue elasticity
• Pelvic floor exercises: Strengthen muscles, improve blood flow
• Balanced diet & hydration: Support overall skin and tissue health
• Non-hormonal options: Vaginal moisturizers (e.g., hyaluronic acid-based) or laser treatments in select cases

Combining prasterone with these strategies often yields the best comfort and quality of life.

Summary

Vaginal DHEA (prasterone) offers a targeted, FDA-approved solution for moderate-to-severe menopausal dryness and dyspareunia. By supplying a local source of DHEA that converts to estrogen and androgen within vaginal cells, it restores tissue health, lubrication, and pH balance without significant systemic hormone exposure. Most women see meaningful relief in 8–12 weeks of daily use.

Key takeaways:

• Insert one 6.5 mg ovule nightly for at least 12 weeks
• Expect mild local side effects; serious risks are rare
• Consult your doctor if you have contraindications or unusual symptoms
