What is Valergen (estradiol (injection))?
Estradiol is a form of estrogen, a female sex hormone that regulates many processes in the body.
Estradiol injection is used to treat certain symptoms of menopause such as hot flashes and vaginal dryness, burning, or irritation. It is also used to treat a lack of estrogen that is caused by ovarian failure or a condition called hypogonadism.
Some forms of estradiol injection are used in men to treat the symptoms of prostate cancer.
