Estrogens increase the risk of endometrial cancer; monitor for abnormal vaginal bleeding. Estrogens with or without progestins should not be used for the prevention of cardiovascular disease or dementia. Increased risks of myocardial infarction, stroke, invasive breast cancer, pulmonary emboli, and deep vein thrombosis in postmenopausal women (50 to 79 years of age) have been reported. An increased risk of developing probable dementia in postmenopausal women 65 years of age or older has also been reported. This product contains an estrogen and androgen, not a progestin.

Uses For Menogen
Esterified estrogens and methyltestosterone combination is used to treat the symptoms of menopause in patients who did not get relief after being treated with estrogens alone. These symptoms may include a feeling of heat, sweating, and warmth in the face, neck, or chest ("hot flashes"); and dryness, burning, and itching in the vagina.
Esterified estrogens are a man-made mixture of estrogens. Estrogen is a hormone that is produced by the body in greater amounts in females. It is necessary for normal sexual development of the female and for regulation of the menstrual cycle during the childbearing years. Methyltestosterone is a man-made form of testosterone, a hormone that is produced by the body in greater amounts in males and small amounts in females. Menopause symptoms occur when the hormone balance changes in the female body. This combination of hormones will relieve the symptoms of menopause by adding more hormones to the body.
This medicine is available only with your doctor's prescription.

This medicine may increase the risk of getting breast cancer. It is very important that you check your breasts on a regular basis for any unusual lumps or discharge, and that you have breast x-rays every year as directed by your doctor. These exams are very important if you have a family member with a history of breast cancer. Talk with your doctor about this risk.
This medicine may increase the risk of getting dementia in elderly women (above 65 years of age). Talk with your doctor if this concerns you.
Check with your doctor right away if blurred vision, difficulty with reading, or any other change in vision occurs during or after treatment. Your doctor may want you to have your eyes checked by an ophthalmologist (eye doctor).

Before you have any medical tests, tell the medical doctor in charge that you are taking this medicine. The results of some tests may be affected by this medicine. Also, you may need to stop using this medicine for a few weeks before and after having surgery, or if you are inactive for a long period of time.
