In short
Prasterone, also known as dehydroepiandrosterone (DHEA) or Intrarosa, is being studied in various clinical trials for its potential benefits in treating menopausal symptoms, vaginal atrophy, and autoimmune conditions like lupus. This article summarizes key findings from recent clinical trials investigating the use of prasterone in different patient populations.

What is Prasterone?
Prasterone, also known as dehydroepiandrosterone (DHEA) or Intrarosa, is a synthetic version of a hormone naturally produced by the human body. It's a medication that has been approved by the U.S. Food and Drug Administration (FDA) for treating certain menopausal symptoms. Prasterone is a type of steroid hormone that can be converted into both estrogen and testosterone in the body.
Conditions Treated with Prasterone
Prasterone is primarily used to treat the following conditions:
- Genitourinary Syndrome of Menopause (GSM): This is a group of symptoms affecting the genital and urinary systems in menopausal women. It includes vaginal dryness, irritation, and pain during sexual intercourse (dyspareunia).
- Vulvovaginal Atrophy (VVA): This is a condition where the vaginal tissues become thin, dry, and inflamed due to a lack of estrogen.
- Recurrent Urinary Tract Infections (UTIs): Some studies are investigating if prasterone can help prevent recurrent UTIs in postmenopausal women.
- Vaginal Symptoms in Cancer Survivors: Research is being conducted on the use of prasterone for vaginal symptoms in cancer survivors, particularly those who have had breast cancer.
How Prasterone Works
Prasterone works by being converted into estrogen and testosterone in the body. These hormones help to improve the health and function of vaginal tissues. Specifically:
- It increases the number of superficial cells in the vagina, which helps maintain vaginal health.
- It decreases the number of parabasal cells, which are associated with vaginal atrophy.
- It helps to lower vaginal pH, creating a healthier vaginal environment.
- It may improve vaginal lubrication and reduce pain during sexual intercourse.
How Prasterone is Administered
Prasterone is typically administered as a vaginal insert. The most common dosage is 6.5 mg, inserted into the vagina once daily at bedtime. It's important to follow your doctor's instructions carefully when using this medication.
Effectiveness of Prasterone
Clinical trials have shown that prasterone can be effective in treating symptoms of GSM and VVA. Some key findings include:
- Improvement in vaginal dryness and pain during intercourse.
- Positive changes in vaginal pH and cell composition.
- Potential improvement in sexual function and quality of life.
Potential Side Effects
While prasterone is generally well-tolerated, it may cause some side effects. These can include:
- Vaginal discharge
- Genital itching or irritation
- Urinary tract infections
It's important to discuss any side effects with your healthcare provider.
Ongoing Research
Researchers are continuing to study prasterone for various uses:
- Its potential in preventing bone loss in women with lupus who are taking glucocorticoids.
- Its use in breast cancer survivors experiencing vaginal symptoms.
- Its effectiveness in preventing recurrent urinary tract infections in postmenopausal women.
As with any medication, it's crucial to consult with your healthcare provider to determine if prasterone is appropriate for your specific situation.
