Estradiol 4 mg is a prescription estrogen medication commonly used in hormone replacement therapy (HRT). It helps balance estrogen levels in individuals experiencing hormonal deficiencies or fluctuations. In women, declining estrogen levels can lead to symptoms such as hot flashes, night sweats, vaginal dryness, mood changes, and bone loss. Estradiol 4 mg supports hormonal balance and helps restore overall well-being. Because of its effectiveness, this medication is widely used across the US, UK, Canada, and Australia.
