Vaginal estrogen is a low-dose local therapy for the genitourinary syndrome of menopause (GSM) — vaginal dryness, painful intercourse, urinary frequency, and recurrent UTIs. It works locally and achieves only minimal systemic absorption.
Available formulations
- Vaginal creams: Estrace cream (estradiol), Premarin cream (conjugated equine estrogens).
- Vaginal tablets / inserts: Vagifem, Yuvafem, Imvexxy (all estradiol).
- Vaginal ring: Estring (low-dose, 3-month ring — treats GSM only) vs. Femring (higher-dose, 3-month ring — also treats systemic symptoms).
Why it’s used differently from systemic HRT
- Serum estradiol remains close to postmenopausal baseline at standard doses.
- Does not require progesterone pairing at standard doses in women with intact uterus.
- Safe for long-term continuous use.
- Appropriate for many women who cannot or choose not to take systemic HRT.
Common use cases
- Women whose only menopause symptom is GSM (no hot flashes).
- Women taking systemic HRT who still have stubborn local symptoms.
- Breast-cancer survivors with severe GSM unresponsive to non-hormonal therapy (with oncologist involvement).
Non-hormonal alternatives
Some patients prefer to try vaginal moisturizers and pH-balancing products first, or DHEA vaginal inserts (Intrarosa). DHEA is hormonal but acts locally. Ospemifene (Osphena) is a non-estrogen oral option.
