Estriol
In StockEstriol is a prescription medicine used to manage menopause-related symptoms such as vaginal dryness, irritation, and other effects of estrogen deficiency. It works by supplying a natural form of estrogen that helps restore hormonal balance and support the health of vaginal and urinary tissues. This action can help improve comfort and hormone-related symptoms. Use as directed on the product label or by a healthcare professional.
What is Estriol?
Estriol is a naturally occurring form of the hormone estrogen. It is considered a weaker estrogen compared to estradiol. Estriol belongs to the class of medications known as estrogen hormone therapies.
Estriol is commonly used to treat:
Vaginal dryness and irritation related to menopause
Pain during intercourse due to low estrogen
Vaginal and urinary symptoms of menopause (genitourinary syndrome of menopause)
Certain cases of estrogen deficiency under specialist care
In some regions, estriol may also be included in compounded hormone preparations.
Available Forms and Strengths
Estriol is available in:
Vaginal creams
Vaginal tablets or pessaries
Vaginal suppositories
Oral tablets (in some countries)
Compounded topical preparations
Strengths vary depending on the formulation and intended use.
What is the Recommended Dosage of Estriol?
The correct dosage depends on:
The condition being treated
Severity of symptoms
Age
Whether the patient has a uterus
Medical history
Liver function
Vaginal estriol is typically used in low doses for local symptoms. Oral or compounded preparations require careful medical supervision.
Dosing must follow instructions from a licensed medical specialist. Do not change the dose or duration without professional guidance.
How Estriol Works
Estriol works by replacing or supplementing estrogen in the body.
Estrogen supports:
Vaginal tissue health
Natural lubrication
Elasticity of vaginal and urinary tissues
Bone health
Hormonal balance
When estrogen levels decline—especially during menopause—vaginal tissues can become thin, dry, and inflamed. Estriol helps restore moisture and tissue thickness, reducing discomfort.
It manages symptoms caused by low estrogen but does not reverse menopause or cure underlying hormonal changes.
Is a Prescription Required to Buy Estriol Online?
In most countries, estriol requires a prescription. Even when available in compounded form, it should be used only under medical supervision.
Patients should consult a licensed medical specialist, such as:
A gynecologist
An endocrinologist
A primary care physician
Hormone therapy requires evaluation of personal risk factors, including blood clot history, cancer history, and liver function.
Avoid purchasing hormone products from unlicensed online sellers. Counterfeit or improperly compounded hormones may pose health risks.
