Aygestin (norethindrone)

Prescription only
Regulates your menstrual cycle and treats irregular bleeding.

Aygestin (norethindrone) regulates the menstrual cycle and treats heavy or irregular vaginal bleeding. It's easy to take and isn't expensive.

3.6/ 7 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.
