Estradiol Valerate Injection 10mg/ml is primarily used to address conditions caused by low estrogen levels. This medication is commonly prescribed for the treatment of moderate to severe vasomotor symptoms (such as hot flashes) and vulvovaginal atrophy that occur as a result of menopause. Additionally, it is used for managing hypoestrogenism due to hypogonadism, primary ovarian failure, or castration. It also serves as a part of hormone therapy for transgender women and, in certain cases, for the palliative treatment of advanced androgen-dependent prostate cancer in men. This injectable form is typically administered intramuscularly under medical supervision.
