Treats low estrogen and relieves menopause symptoms.

Combipatch (estradiol / norethindrone patch) is a twice weekly patch that effectively treats menopause and causes less blood clots or stroke than combination pills.

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
  • Twice weekly patch. Good for people who don't want to take daily pills.
  • Replenishes estrogen to your whole body and relieves multiple symptoms due to low estrogen (hot flashes, vaginal dryness).
  • Less likely to cause blood clots or stroke than pills since patches contain a lower amount of hormones.
  • Good for women with an intact uterus.
  • You can bathe, shower, and swim while wearing the patch, as long as you don't rub the patch.
  • 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
  • More potential side effects than single ingredient medications since it exposes your whole body to two hormones.
  • You may get irregular bleeding and spotting that can last a few months to a year.
  • The patch can't be exposed to direct sunlight for long periods of time.
  • Can be expensive since it's only available as a brand name product.
  • 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.
