Why is Premia (Premphase, Prempro) rx prescribed?

Premia (Premphase, Prempro) rx is an estrogen replacement drug. The tablets are used to reduce moderate to severe symptoms of menopause, including feelings of warmth in the face, neck, and chest, and the sudden intense episodes of heat and sweating known as "hot flashes." Cenestin tablets, containing a synthetic form of conjugated estrogens, may also be prescribed for these symptoms.

In addition to the symptoms of menopause, Premia (Premphase, Prempro) rx tablets are prescribed for teenagers who fail to mature at the usual rate, and to relieve the symptoms of certain types of cancer, including some forms of breast and prostate cancer.

Before taking Premia (Premphase, Prempro) rx solely for this purpose, you should carefully consider using alternative, nonestrogen therapies.

The addition of progesterone to estrogen-replacement therapy has been shown to reduce the risk of uterine cancer. Prempro combines estrogen and progesterone in a single tablet taken once daily. Premphase is a 28-day supply of tablets. The first 14 contain only estrogen. The second 14 supply both estrogen and progesterone. Both Prempro and Premphase are prescribed to reduce the symptoms of menopause, including vaginal problems, and to prevent osteoporosis.

Special warnings about Premia (Premphase, Prempro) rx

For women who have not had a hysterectomy, the risk of endometrial and uterine cancer increases when estrogen-only drugs are used for a long time or taken in large doses.

If you've had a hysterectomy but still have residual endometriosis, your doctor may want you to use an estrogen/progesterone combination.

Certain studies have shown that women taking estrogen for prolonged periods of time (4 years or more) face an increased risk of breast cancer, and a study by the National Heart, Lung and Blood Institute (NHLBI) has confirmed an increased risk among women taking estrogen/progesterone combinations. Use combination products (and estrogen-only preparations, too) with special caution if you have a family history of breast cancer or have ever had an abnormal mammogram. Be sure to get an annual breast exam from your doctor, and do your own self-examination each month.

The NHLBI study also found an increased risk of dementia for women taking estrogen or estrogen/progesterone combinations.
