About Estradiol Valerate
Indications of Estradiol Valerate
Estradiol Valerate is an injectable estrogen ester used mainly in postmenopausal hormone therapy. Established, FDA-approved indications include:
- Moderate to severe vasomotor symptoms (hot flashes and night sweats) associated with menopause.
- Moderate to severe symptoms of vulvar and vaginal atrophy due to menopause, although low-dose topical or vaginal estrogen products are generally preferred when systemic therapy is not otherwise needed.
- Hypoestrogenism due to hypogonadism, castration, or primary ovarian failure.
- Palliative treatment of advanced, androgen-dependent carcinoma of the prostate in men (not curative), as adjunct hormonal therapy.
Estradiol Valerate is also used as a component of certain combined estrogen-progestin hormone replacement or contraceptive regimens; it is not intended for use as a contraceptive on its own.
Estradiol Valerate is not indicated for the prevention of cardiovascular disease or dementia and should not be used for this purpose.
Dosage & Administration of Estradiol Valerate
| Indication | Typical Adult Dose of Estradiol Valerate |
|---|---|
| Vasomotor symptoms of menopause / vulvovaginal atrophy | 10-20 mg by deep intramuscular injection every 4 weeks; use the lowest effective dose and attempt to taper or discontinue at 3-6 month intervals. |
| Female hypoestrogenism (hypogonadism, castration, primary ovarian failure) | 10-20 mg by deep intramuscular injection every 4 weeks, individualized to symptom control. |
| Palliative therapy of advanced androgen-dependent prostate cancer | 30 mg or more by deep intramuscular injection every 1-2 weeks, under specialist supervision. |
Women with an intact uterus generally require concomitant progestin therapy alongside Estradiol Valerate to reduce the risk of endometrial hyperplasia/cancer associated with unopposed estrogen use (see Precautions and Warnings).

Frequently Asked Questions about Estradiol Valerate
What is Estradiol Valerate used for?
Estradiol Valerate is mainly used to relieve moderate to severe menopausal symptoms such as hot flashes and vaginal dryness, to treat low estrogen levels caused by ovarian failure or removal of the ovaries, and as palliative treatment for advanced prostate cancer in men.
How is Estradiol Valerate given?
Estradiol Valerate is given as a deep intramuscular injection, usually every 4 weeks for menopausal symptoms, by a trained healthcare professional. It should never be self-injected without medical guidance.
Can Estradiol Valerate be used during pregnancy?
No. Estradiol Valerate is contraindicated during pregnancy, and treatment should be stopped immediately if pregnancy occurs or is suspected.
Is Estradiol Valerate safe while breastfeeding?
Estradiol Valerate can reduce the amount and quality of breast milk and passes into breast milk in small amounts, so it should generally be avoided during breastfeeding unless a physician determines the benefits outweigh the risks.
What are the serious risks of Estradiol Valerate?
Estrogen therapy, including Estradiol Valerate, carries an increased risk of blood clots, stroke, heart attack, and — in women with an intact uterus who are not also taking a progestin — endometrial cancer. Long-term use is also associated with a higher risk of breast cancer. Report unusual vaginal bleeding, leg swelling, chest pain, or sudden severe headache to your doctor immediately.
Who should not use Estradiol Valerate?
Women with undiagnosed vaginal bleeding, known or suspected breast cancer, a history of blood clots or stroke, active liver disease, or known/suspected pregnancy should not use Estradiol Valerate. Always disclose your full medical history to your physician before starting treatment.
