(Estradiol Patch)

Regulates your menstrual cycle and supplements estrogen treatments for menopause. Provera (Medroxyprogesterone) works well to regulate your menstrual cycle and stop irregular bleeding. It also protects the uterus from estrogen's harmful effects.Treats low estrogen, relieves menopause symptoms, and lowers your risk of osteoporosis. The Alora (Estradiol Patch) needs to be replaced twice a week, and it may have fewer side effects than oral estrogen pills.
How it works
Provera (Medroxyprogesterone) contains medroxyprogesterone, a progesterone hormone that works to balance hormone changes in the body. In premenopausal women, it prevents thickening of the uterus lining and regulates your menstrual cycle. It's also added to hormone therapy to protect the uterus from the harmful effects of estrogen.The Alora (Estradiol Patch) replaces an estrogen hormone, estradiol, that your body loses during and after menopause. Higher levels of estradiol relieve symptoms of low estrogen and menopause and prevent bone loss.

  • Provera (Medroxyprogesterone) can be used to treat multiple hormone problems in women.
  • After menopause, taking estrogen raises your risk of uterine cancer. However, taking progesterone, like in Provera (Medroxyprogesterone), along with estrogen gives you the positive effects of estrogen, but also prevents it from damaging your uterus.

  • The Alora (Estradiol Patch) replenishes estrogen to your whole body and relieves multiple symptoms due to low estrogen, like hot flashes and vaginal dryness.
  • The patch is good for people who don't want to take daily pills.
  • Can be worn while swimming, bathing, and showering.
  • By using a patch instead of a pill, there's a lower risk of side effects such as blood clots and stroke since lower amounts of estrogen are used in patches.

  • Improves mood, energy, and mental alertness for some people.

  • You need to replace the Alora (Estradiol Patch) twice a week, compared to other patches that are once a week.

Tips from our pharmacists for people taking the medication
  • The dose of Provera (Medroxyprogesterone) will be different depending on what you’re using it for, so take it exactly the way your doctor tells you.
  • Talk to your doctor every few months about using the lowest possible dose of Provera (Medroxyprogesterone). Since there can be a lot of long-term side effects, take it only as long as you need it.
  • Can cause headache, weight gain, breast tenderness, or changes in mood.
  • If you're taking Provera (Medroxyprogesterone) to regulate your period, you'll get withdrawal bleeding 3 to 7 days after stopping Provera (Medroxyprogesterone).
  • Remove the patch by tearing the package by hand and not with scissors. Never cut the patch.
  • Apply the sticky side of the patch to clean, dry, hairless skin below your waistline on areas as instructed by the manufacturer (never on your breast).
  • Replace the patch twice a week (every 3-4 days) on a different area of the skin to lower the risk of skin irritation.
  • Fold together the sticky sides of used patches before throwing them away to avoid exposing others to the medicine. Don't flush them down the toilet.
  • Shouldn't be used forever. Talk to your doctor regularly to see if you still need treatment.
  • Can cause nausea, dizziness, bloating, and breast tenderness.
  • Tell your doctor about any unusual vaginal bleeding.
  • Get emergency care if you notice unexplained swelling and pain in your limbs, shortness of breath, chest pain, severe headache, or changes in vision.
