Regulates your menstrual cycle and treats irregular bleeding.

2.7/ 5 average rating with 30 reviewsforAygestin
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
  • Helps to regulate your period.
  • Decreases bleeding from hormone imbalance.
  • Available as a generic medication, so it costs less.
  • 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
  • Can make you gain weight.
  • Higher risk of blood clots.
  • Not for people who are post-menopausal, pregnant, or breast-feeding.
  • Can cause a lot of side effects.
  • 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.
