Estradiol

Estradiol is the primary form of estrogen in the female body, and it plays a vital role in regulating a variety of bodily functions, from bone health to heart health. However, as women age and go through menopause or have a hysterectomy, their natural production of estradiol decreases, leading to a variety of unpleasant symptoms such as hot flashes, vaginal dryness, mood changes, or insomnia.

Bioidentical estradiol is designed to mimic the structure and function of the natural hormone, providing a safe and effective way to replenish your body’s supply of this vital hormone.

Estradiol Clinical Information

What Estradiol Is

Estradiol is the primary biologically active estrogen in women of reproductive age. As a prescription bioidentical hormone therapy, estradiol is most commonly delivered transdermally (patch, gel, cream), vaginally (cream, tablet, ring), or orally. Transdermal routes bypass first-pass liver metabolism and have a more favorable clotting profile than oral estrogen.

Indications

  • Perimenopausal and menopausal vasomotor symptoms (hot flashes, night sweats)
  • Genitourinary syndrome of menopause (vaginal dryness, urinary symptoms)
  • Mood, sleep, and cognitive support during the menopausal transition
  • Bone density preservation in appropriate candidates

Contraindications

  • Personal history of estrogen-sensitive cancer (breast, endometrial)
  • Active or recent venous thromboembolism (clot)
  • Active liver disease
  • Unexplained vaginal bleeding
  • Known thrombophilia disorders
  • Pregnancy

Use with Caution

  • Strong family history of breast cancer (case-by-case discussion)
  • Migraine with aura (transdermal preferred over oral)
  • Hypertriglyceridemia
  • Gallbladder disease

Important: Estrogen + Progesterone

Women with an intact uterus require progesterone alongside estradiol to protect the uterine lining. Estrogen alone in women with a uterus significantly increases endometrial cancer risk. Women without a uterus may use estradiol monotherapy.

Monitoring

Baseline labs (estradiol, FSH, LH, lipids, liver function, mammogram per guidelines), symptom review at 3 and 6 months, dose adjustment as needed.
