PREMPHASE®
(Conjugated Estrogens plus Medroxyprogesterone Acetate) Tablets

Read this PATIENT INFORMATION before you start taking PREMPRO or PREMPHASE and read what you get each time you refill your PREMPRO or PREMPHASE prescription. There may be new information. This information does not take the place of talking to your healthcare provider about your medical condition or your treatment.

What is the most important information I should know about PREMPRO and PREMPHASE (combinations of estrogens and a progestin)?

  • Do not use estrogens with progestins to prevent heart disease, heart attacks, strokes, or dementia (decline of brain function)
  • Using estrogens with progestins may increase your chances of getting heart attacks, strokes, breast cancer, or blood clots
  • Using estrogens with progestins may increase your chance of getting dementia, based on a study of women 65 years of age or older
  • Do not use estrogen-alone to prevent heart disease, heart attacks, strokes or dementia
  • Using estrogen-alone may increase your chance of getting cancer of the uterus (womb)
  • Using estrogen-alone may increase your chances of getting strokes or blood clots
  • Using estrogen-alone may increase your chance of getting dementia, based on a study of women 65 years of age or older
  • You and your healthcare provider should talk regularly about whether you still need treatment with PREMPRO or PREMPHASE

What is PREMPRO or PREMPHASE?

PREMPRO or PREMPHASE are medicines that contain two kinds of hormones, estrogens and a progestin.

What is PREMPRO or PREMPHASE used for?

PREMPRO or PREMPHASE is used after menopause to:

  • Reduce moderate to severe hot flashes

Estrogens are hormones made by a woman's ovaries. The ovaries normally stop making estrogens when a woman is between 45 and 55 years 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 strong feelings 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.

  • Treat menopausal changes in and around the vagina

You and your healthcare provider should talk regularly about whether you still need treatment with PREMPRO or PREMPHASE to control these problems. If you use PREMPRO or PREMPHASE 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)

Osteoporosis from menopause is a thinning of the bones that makes them weaker and easier to break. If you use PREMPRO or PREMPHASE only to prevent osteoporosis due to menopause, talk with your healthcare provider about whether a different treatment or medicine without estrogens might be better for you. Weight-bearing exercise, like walking or running, and taking calcium (1500 mg per day of elemental calcium) and vitamin D (400-800 IU per day) supplements may also lower your chances of getting postmenopausal osteoporosis. It is important to talk about exercise and supplements with your healthcare provider before starting them.

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

Who should not take PREMPRO or PREMPHASE?

Do not take PREMPRO or PREMPHASE if you have had your uterus (womb) removed (hysterectomy).

PREMPRO and PREMPHASE contain 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 PREMPRO or PREMPHASE.

Do not take PREMPRO or PREMPHASE if you:

  • Have unusual vaginal bleeding
  • 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 use PREMPRO or PREMPHASE.

  • 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 PREMPRO or PREMPHASE or any of their ingredients

See the list of ingredients in PREMPRO and PREMPHASE at the end of this leaflet.

  • Think you may be pregnant

Tell your healthcare provider

  • If you have any 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.

  • About all of your medical problems

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

  • About all the medicines you take

This includes prescription and nonprescription medicines, vitamins, and herbal supplements. Some medicines may affect how PREMPRO or PREMPHASE works. PREMPRO or PREMPHASE may also affect how your other medicines work.

  • If you are going to have surgery or will be on bedrest

You may need to stop taking PREMPRO or PREMPHASE.

  • If you are breastfeeding

The hormones in PREMPRO and PREMPHASE can pass into your breast milk.

How should I take PREMPRO or PREMPHASE?

  • Take one PREMPRO or PREMPHASE tablet at the same time each day
  • If you miss a dose, take it as soon as possible
    If it is almost time for your next dose, skip the missed dose and go back to your normal schedule. Do not take 2 doses at the same time.
  • Estrogens should be used at the lowest dose possible for your treatment only as long as needed

You and your healthcare provider should talk regularly (for example, every 3 to 6 months) about the dose you are taking and whether you still need treatment with PREMPRO or PREMPHASE.

What are the possible side effects of PREMPRO or PREMPHASE?

Side effects are grouped by how serious they are and how often they happen when you are treated.

Serious, but less common side effects include:

Call your healthcare provider right away if you get any of the following warning signs or any other unusual symptoms that concern you:

  • New breast lumps
  • Unusual vaginal bleeding
  • Changes in vision or speech

What can I do to lower my chances of getting a serious side effect with PREMPRO or PREMPHASE?

  • See your healthcare provider right away if you get vaginal bleeding while taking PREMPRO or PREMPHASE
  • Have a pelvic exam, breast exam and mammogram (breast X-ray) every year unless your healthcare provider tells you something else
    If members of your family have had breast cancer or if you have ever had breast lumps or an abnormal mammogram, you may need to have breast exams more often.
  • If you have high blood pressure, high cholesterol (fat in the blood), diabetes, are overweight, or if you use tobacco, you may have higher chances for getting heart disease

Ask your healthcare provider for ways to lower your chances of getting heart disease.
