Available forms of estradiol

Estradiol is a form of estrogen, a female sex hormone that regulates many processes in the body. Estradiol is critical for the development and maintenance of female reproductive tissues but also has important roles in other tissues and organs. This hormone is available in several forms for therapeutic use, each designed to address specific needs and conditions related to estrogen deficiency or imbalance.

Forms of Estradiol

Estradiol is available in various forms, including oral tablets, transdermal patches, topical gels, vaginal creams, and injections. Each form has its specific indications, advantages, and limitations.

Oral Tablets

Oral tablets are one of the most common forms of estradiol therapy. They are used for hormone replacement therapy (HRT) in postmenopausal women, among other indications. Brands include Estrace, Estradiol, and Femtrace.

Transdermal Patches

Transdermal patches, such as Climara and Vivelle-Dot, deliver estradiol directly through the skin into the bloodstream. This method bypasses the liver and may reduce the risk of certain side effects associated with oral forms.

Topical Gels

Topical gels like EstroGel are applied to the skin, offering another alternative for estrogen delivery that avoids first-pass metabolism by the liver. This form is particularly useful for those who prefer a non-oral and non-invasive option.

Vaginal Creams

Vaginal creams, including Estrace Cream and Premarin Cream, are used to treat vaginal symptoms of menopause such as dryness, itching, and burning.

Injections

Estradiol valerate (Delestrogen) and estradiol cypionate (Depo-Estradiol) are injectable forms of estradiol. They are typically used for their long-acting effects in hormone therapy for transgender women and in certain cases of hormone replacement therapy.

Indications

Estradiol is used to treat symptoms of menopause such as hot flashes, vaginal dryness, and irritation. It is also used in the treatment of hypoestrogenism, as part of transgender hormone therapy, and for preventing osteoporosis in postmenopausal women.

Side Effects

Common side effects of estradiol include nausea, vomiting, bloating, breast tenderness, headache, and changes in weight. More serious risks include an increased risk of blood clots, stroke, and certain types of cancers.
