💡 Quick Answer
Evalon Cream (estriol 1 mg/g) is a vaginal estrogen cream used to treat genitourinary syndrome of menopause (GSM) — vaginal dryness, painful sex, and recurrent urinary tract infections. It delivers estriol locally with minimal systemic absorption, making it one of the best-tolerated hormone therapies for postmenopausal women. One tube typically covers an initial 3-week loading course plus ongoing twice-weekly maintenance.

What Is Evalon Cream?
Evalon is a vaginal cream containing estriol 1 mg per gram. Estriol is the weakest of the three naturally occurring human estrogens (the others being estradiol and estrone). Because estriol acts locally on vaginal and urethral tissue with minimal absorption into the bloodstream, it is classified as a local (non-systemic) hormone therapy.
The cream is used to restore the vaginal epithelium after menopause, when declining estrogen causes the tissue to thin, dry, and become more susceptible to injury and infection — a condition called genitourinary syndrome of menopause (GSM), previously known as vaginal atrophy or atrophic vaginitis.
Key Takeaways
- Active ingredient: estriol 1 mg/g (weakest natural estrogen)
- Route: vaginal application via supplied applicator
- Primary use: vaginal dryness, dyspareunia, recurrent UTIs in postmenopausal women
- Systemic absorption is very low — progestin cover is generally not required
- Available without systemic HRT as a standalone local treatment
What Conditions Does Evalon Treat?
Evalon is indicated for the full spectrum of GSM symptoms:
- Vaginal dryness and itching — the most common GSM complaint, affecting up to 60% of postmenopausal women
- Dyspareunia (painful intercourse) — thinning vaginal walls cause microtears and burning during sex
- Recurrent urinary tract infections (rUTIs) — low vaginal estrogen allows colonisation by pathogenic bacteria; local estriol restores protective flora
- Urinary urgency and frequency — estriol improves urethral mucosal integrity, reducing urge symptoms
- Vulvar irritation and inflammation — restores epithelial thickness and natural secretions
Unlike systemic HRT, Evalon does not relieve hot flushes or night sweats — it targets only the urogenital tissues.
How Estriol Works in the Vagina
After menopause, the vaginal epithelium depends almost entirely on estrogen for maintenance. When estrogen levels fall, the epithelium thins from its normal 15–20 cell layers to 2–4 layers, glycogen content drops, and vaginal pH rises from the healthy 3.8–4.5 to 6.0–7.5. This creates a hostile environment for Lactobacillus (the protective dominant species) and an inviting one for Escherichia coli, Klebsiella, and other pathogens.
Estriol applied vaginally:
- Binds estrogen receptors in vaginal epithelial cells
- Stimulates proliferation and cornification of the epithelium
- Restores glycogen production → lowers vaginal pH → Lactobacillus re-establishes
- Increases vaginal secretions and natural lubrication
- Thickens the urethral mucosa → reduces urgency and UTI susceptibility
Because estriol has a lower binding affinity for estrogen receptors than estradiol and a very short nuclear retention time, systemic effects are minimal even with prolonged use.
Dosage and How to Use the Applicator
Evalon is supplied with a calibrated vaginal applicator (typically delivering 0.5 g of cream per application = 0.5 mg estriol).
| Phase | Dose | Frequency | Duration |
|---|---|---|---|
| Loading (induction) | 0.5 g (1 applicator) | Once daily at bedtime | 3 weeks |
| Maintenance | 0.5 g (1 applicator) | Twice weekly | Ongoing (reassess annually) |
Application steps:
- Wash hands thoroughly
- Fill the applicator to the calibration line (0.5 g)
- Lie on your back with knees bent, or stand with one foot raised
- Gently insert the applicator into the vagina as far as comfortable
- Depress the plunger slowly to deposit the cream
- Withdraw the applicator and wash it with warm water (reusable)
Bedtime application reduces leakage. If you use a vaginal ring or pessary for prolapse, remove it before applying and reinsert after.
Safety Profile: Is Estriol Safer Than Estradiol?
The key safety advantage of local estriol over systemic estradiol-based HRT is low bioavailability. Studies consistently show that vaginal estriol at standard maintenance doses keeps serum estriol levels within normal postmenopausal range, with no significant increase in estradiol or estrone.
Who is this for?
Local estriol like Evalon is suitable for postmenopausal women who:
- Have GSM symptoms but don’t want or can’t use systemic HRT
- Are breast cancer survivors on aromatase inhibitors (discuss with oncologist first)
- Have tried over-the-counter lubricants and moisturisers without adequate relief
- Experience recurrent UTIs post-menopause
Unlike systemic HRT, local estriol does not require concurrent progestogen even in women with an intact uterus — at maintenance doses, endometrial stimulation is negligible. This is recognised in guidelines from the British Menopause Society and NAMS.
Common side effects
- Mild vaginal burning or irritation on first applications (resolves as tissue heals)
- Increased vaginal discharge initially
- Breast tenderness (rare at low doses)
When to avoid
- Undiagnosed vaginal bleeding
- Known or suspected hormone-sensitive cancers (without specialist guidance)
- Porphyria
- Active or recent thromboembolism (systemic risk is very low with vaginal route, but discuss with your clinician)
Evalon vs Other Vaginal Estrogen Products
| Product | Estrogen | Form | Systemic absorption |
|---|---|---|---|
| Evalon | Estriol 1 mg/g | Cream | Very low |
| Ovestin | Estriol 1 mg/g | Cream | Very low |
| Vagifem / Vagirux | Estradiol 10 mcg | Tablet | Very low |
| Estring | Estradiol 7.5 mcg/day | Ring (90-day) | Very low |
Evalon and Ovestin are both estriol 1 mg/g creams — the difference is manufacturer and regional availability. Both are equally effective.
How Long Before Evalon Works?
Most women notice improvement in vaginal dryness and discomfort within 2–4 weeks of starting the daily loading course. Full restoration of vaginal epithelial thickness — and meaningful reduction in recurrent UTI frequency — typically takes 8–12 weeks of regular use.
Symptoms return gradually if treatment is stopped for several months, so most clinicians recommend ongoing twice-weekly maintenance indefinitely, with annual review.
Frequently Asked Questions
Do I need a progestogen (progesterone) with Evalon?
No — at standard maintenance doses, vaginal estriol does not significantly stimulate the endometrium. Guidelines from the British Menopause Society and the International Menopause Society state that progestogen is not required with low-dose local vaginal estrogen. If you are also using systemic HRT, the systemic progestogen component provides endometrial protection anyway.
Can I use Evalon with a lubricant?
Yes, but avoid applying lubricants at the same time — use them on separate occasions. Oil-based lubricants can degrade the silicone-based components in the applicator. Water-based lubricants are fine alongside Evalon use.
Is Evalon safe for breast cancer survivors?
This is an active area of clinical debate. Low-dose local vaginal estrogen has minimal systemic absorption and is generally considered low-risk, but women on aromatase inhibitors for hormone-receptor-positive breast cancer should discuss with their oncologist before starting. Several oncology guidelines now permit low-dose local vaginal estrogen when lubricants and moisturisers are inadequate.
Can Evalon treat urinary incontinence?
Evalon can help with urge urinary incontinence and urgency-frequency syndrome related to urogenital atrophy, by restoring urethral mucosal health. It does not treat stress urinary incontinence (the kind caused by a weakened pelvic floor).
How do I order Evalon without a prescription?
