Uses For Ogen 2.5

Estrogens are female hormones. They are produced by the body and are necessary for the normal sexual development of the female and for the regulation of the menstrual cycle during the childbearing years.

The ovaries begin to produce less estrogen after menopause (the change of life). This medicine is prescribed to make up for the lower amount of estrogen. Estrogens help relieve signs of menopause, such as hot flashes and unusual sweating, chills, faintness, or dizziness.

Estrogens are prescribed for several reasons:

  • To provide additional hormone when the body does not produce enough of its own, such as during menopause or when female puberty (development of female sexual organs) does not occur on time. Other conditions include a genital skin condition (vulvar atrophy), inflammation of the vagina (atrophic vaginitis), or ovary problems (female hypogonadism or failure or removal of both ovaries).
  • To help prevent weakening of bones (osteoporosis) in women past menopause.
  • In the treatment of selected cases of breast cancer in men and women.
  • In the treatment of cancer of the prostate in men.

Estrogens may also be used for other conditions as determined by your doctor.

There is no medical evidence to support the belief that the use of estrogens will keep the patient feeling young, keep the skin soft, or delay the appearance of wrinkles. Nor has it been proven that the use of estrogens during menopause will relieve emotional and nervous symptoms, unless these symptoms are caused by other menopausal symptoms, such as hot flashes or hot flushes.

Estrogens are available only with your doctor's prescription.

Ogen 2.5 Side Effects

Women rarely have severe side effects from taking estrogens to replace estrogen. Discuss these possible effects with your doctor:

The prolonged use of estrogens has been reported to increase the risk of endometrial cancer (cancer of the lining of the uterus) in women after menopause. This risk seems to increase as the dose and the length of use increase. When estrogens are used in low doses for less than 1 year, there is less risk. The risk is also reduced if a progestin (another female hormone) is added to, or replaces part of, your estrogen dose. If the uterus has been removed by surgery (total hysterectomy), there is no risk of endometrial cancer.

Although the incidence is low, the use of estrogens may increase you chance of getting cancer of the breast. Breast cancer has been reported in men taking estrogens.

Along with its needed effects, a medicine may cause some unwanted effects. Although not all of these side effects may occur, if they do occur they may need medical attention.

The following side effects may be caused by blood clots, which could lead to stroke, heart attack, or death. These side effects occur rarely, and, when they do occur, they occur in men treated for cancer using high doses of estrogens.
