Estradiol — Uses, Dosage, Side Effects & Safety

Drug class: Endocrine & Hormonal

Overview

Estradiol is a form of estrogen, a female sex hormone produced naturally by the ovaries. It is commonly prescribed to manage symptoms of menopause such as hot flashes, vaginal dryness, and osteoporosis prevention. Estradiol may also be used in hormone replacement therapy (HRT) for women with ovarian failure or certain conditions that cause low estrogen levels. This medication works by supplementing the body’s natural estrogen, helping to restore hormonal balance and relieve menopausal symptoms. Estradiol is available in several forms, including oral tablets, skin patches, gels, creams, vaginal rings, and injections. Key points for patients: Estradiol should be used at the lowest effective dose for the shortest duration necessary. Regular follow-up with your healthcare provider is important to monitor for side effects and ensure the medication is working as intended.
