What is Ogen 2.5?
Ogen 2.5 is a form of estrogen, a female sex hormone produced by the ovaries. Estrogen is necessary for many processes in the body.
Ogen 2.5 is used to treat menopause symptoms such as hot flashes and vaginal changes, and to prevent osteoporosis (bone loss) in menopausal women. This medicine is also used to replace estrogen in women with ovarian failure or other conditions that cause a lack of natural estrogen in the body.

Do not use if you are pregnant.
Ogen 2.5 may increase your risk of developing a condition that may lead to uterine cancer. Report any unusual vaginal bleeding right away.
Using this medicine can increase your risk of blood clots, stroke, or heart attack. Ogen 2.5 should not be used to prevent heart disease, stroke, or dementia. Long-term use may increase your risk of cancer of the breast, uterus, or ovaries.
