Head-to-head comparisons of medication uses, side effects, ratings, and more.

Estrace (Estradiol)

Prescription only
Relieves hot flashes and vaginal symptoms related to menopause.

Estrace (Estradiol) treats symptoms of menopause, but causes more of side effects than other medicines like it.

Relieves menopause symptoms and lowers your risk of osteoporosis.

Prefest (Estradiol / Norgestimate) is effective at treating symptoms related to menopause and bone loss. It has a difficult dosing schedule to follow, but doesn't affect your cholesterol and triglyceride levels as much as other estrogen products.

Upsides
  • Estrace (Estradiol) comes as a pill and is much easier to use compared to the cream form.
  • Available as a cheaper, generic version.
  • Usually you only need to take DRUG NAME for a short amount of time.
  • Prefest (Estradiol / Norgestimate) replenishes estrogen to your whole body and relieves multiple symptoms due to low estrogen (hot flashes, night sweats, vaginal dryness).
  • Lowers your risk of fractures by keeping your bones healthy. Make sure you also get enough calcium and Vitamin D.
  • Improves mood, energy, and mental alertness for some people.
  • Good for women with an intact uterus. The norgestimate (a progestin) protects against the risk of cancer in the uterus caused by estrogen treatment.
  • Doesn't affect your cholesterol levels as much as other estrogen treatments.
Downsides
  • Associated with a higher risk for side effects like blood clots, stroke, and cancer compared to its cream formulation.
  • DRUG_ NAME can increase the risk of memory loss for women age 65 or older.
  • Your doctor might frequently change your dose of the medicine in the beginning until your symptoms are well-controlled.
  • Not recommended for women who need treatment only for vaginal dryness and itching.
  • More potential side effects since it exposes your whole body to two hormones, estrogen and norgestimate (a progestin).
  • Dosing schedule can be hard to follow with the 2 different kind of pills (estrogen-only and estrogen/progestin pills).
  • Increases your risk of developing blood clots and stroke.
  • You may get irregular bleeding and spotting that can last a few months to a year.
