  • Do not use estrogen-alone to prevent heart disease, heart attacks, strokes or dementia.
  • Taking estrogen-alone may increase your chance of getting cancer of the uterus (womb).

What is Lopreeza?

Lopreeza is a prescription medicine that contains two kinds of hormones, an estrogen and a progestin.

What is Lopreeza used for?

Lopreeza is used after menopause to:

  • reduce moderate to severe hot flushes

    Estrogens are hormones made by a woman’s ovaries. The ovaries normally stop making estrogens when a woman is between 45 and 55 yrs old. This drop in body estrogen levels causes the “change of life” or menopause, the end of monthly menstrual periods. Sometimes both ovaries are removed during an operation before natural menopause takes place. The sudden drop in estrogen levels causes “surgical menopause.”

    When the estrogen levels begin dropping, some women get very uncomfortable symptoms, such as feelings of warmth in the face, neck, and chest, or sudden, intense episodes of heat and sweating (“hot flashes” or “hot flushes”). In some women, the symptoms are mild, and they will not need to take estrogens. In other women, symptoms can be more severe. You and your healthcare provider should talk regularly about whether or not you still need treatment with Lopreeza.

  • treat moderate to severe menopausal changes in and around the vagina

    You and your healthcare provider should talk regularly about whether you still need treatment with Lopreeza 1.0 mg/0.5 mg to treat these problems. If you use Lopreeza 1.0 mg/0.5 mg only to treat your menopausal changes in and around your vagina, talk with your healthcare provider about whether a topical vaginal product would be better for you.

  • help reduce your chances of getting osteoporosis (thin weak bones)

    If you use Lopreeza only to prevent osteoporosis from menopause, talk to your healthcare provider about whether a different treatment or medicine without estrogens might be better for you.

    You and your healthcare provider should talk regularly about whether you still need treatment with Lopreeza.

    Who should not take Lopreeza?

    Do not take Lopreeza if you have had your uterus (womb) removed (hysterectomy).

    Lopreeza contains a progestin to decrease the chance of getting cancer of the uterus. If you do not have a uterus, you do not need a progestin and you should not take Lopreeza.

    Do not take Lopreeza if you:

  • have unusual vaginal bleeding

    Vaginal bleeding after menopause may be a warning sign of cancer of the uterus (womb). Your healthcare provider should check any unusual vaginal bleeding to find out the cause.

  • currently have or have had certain cancers

Estrogens may increase the chance of getting certain types of cancers, including cancer of the breast or uterus. If you have or have had cancer, talk with your healthcare provider about whether you should take Lopreeza.

  • had a stroke or heart attack
  • currently have or have had blood clots
  • currently have or have had liver problems
  • have been diagnosed with a bleeding disorder
  • are allergic to Lopreeza or any of its ingredients

See the list of ingredients in Lopreeza at the end of this leaflet.

  • think you may be pregnant

    Lopreeza is not for pregnant women. If you think you may be pregnant, you should have a pregnancy test and know the results. Do not take Lopreeza if the test is positive and talk to your healthcare provider.

    What should I tell my healthcare provider before taking Lopreeza?

    Before you take Lopreeza, tell your healthcare provider if you:

  • have any unusual vaginal bleeding

    Vaginal bleeding after menopause may bea warning sign of cancer of the uterus (womb). Your healthcare provider should check any unusual vaginal bleeding to find out the cause.

  • have any other medical conditions

    Your healthcare provider may need to check you morecarefully if you have certain conditions, such as asthma (wheezing), epilepsy (seizures), diabetes, migraine, endometriosis, lupus, angioedema (swelling of face and tongue), or problems with your heart, liver, thyroid, kidneys, or have high calcium levels in your blood.

  • are going to have surgery or will be on bed rest

Your healthcare provider will let you know if you need to stop taking Lopreeza.

  • are breast feeding

The hormones in Lopreeza can pass into your breast milk.

Tell your healthcare provider about all the medicines you take, includingprescription and nonprescription medicines, vitamins, and herbal supplements. Some medicines may affect how Lopreeza works.
