Estradiol valerate is a medication primarily used for hormone replacement therapy (HRT) in transgender women and for menopausal hormone therapy in cisgender women. While it can be effective in managing symptoms and achieving desired hormonal levels, like any medication, it carries certain risks. Here are some of the potential risks associated with taking estradiol valerate:

  • Cardiovascular Risks: There is an increased risk of cardiovascular events, including heart attacks and strokes, particularly in older individuals or those with pre-existing cardiovascular conditions.
  • Thromboembolic Events: Estradiol valerate can increase the risk of blood clots forming in veins (venous thromboembolism), which can lead to serious complications such as pulmonary embolism.
  • Breast Cancer: Long-term use of estrogen therapy, including estradiol valerate, may be associated with an increased risk of breast cancer. This risk may vary depending on factors such as age, duration of therapy, and personal medical history.
  • Endometrial Cancer: Estrogen therapy without the addition of progestin in individuals with an intact uterus may increase the risk of endometrial cancer (cancer of the lining of the uterus).
  • Gallbladder Disease: There is a potential increased risk of gallbladder disease, including gallstones, in individuals taking estrogen therapy.
  • Mood Changes: Some individuals may experience mood changes, including depression or mood swings, while taking estradiol valerate.
  • Fluid Retention: Estrogen therapy can sometimes cause fluid retention, leading to swelling or bloating.
  • Elevated Blood Pressure: Estrogen therapy may lead to elevated blood pressure in some individuals.

It’s essential for individuals considering or currently taking estradiol valerate to discuss these risks with their healthcare provider. The decision to use hormone therapy should be based on a thorough evaluation of individual health risks and benefits, and ongoing monitoring is typically recommended to manage any potential adverse effects.

Why is this medication prescribed?

Estradiol valerate is a medication primarily prescribed for hormone replacement therapy (HRT) in women who are experiencing symptoms of menopause. It is a synthetic form of estrogen, which is the primary female sex hormone. Estradiol valerate helps to alleviate symptoms associated with menopause such as hot flashes, vaginal dryness, night sweats, and mood swings. It can also be used in transgender hormone therapy to feminize the body by promoting the development of female secondary sexual characteristics.

How should this medicine be used?

Estradiol valerate injection is typically administered by a healthcare professional, although in some cases, individuals may be trained to self-administer the injections at home. Here’s a general guideline on how estradiol valerate injection is used:

  • Preparation: Ensure you have the correct dosage of estradiol valerate and the necessary supplies, including syringes and needles. Wash your hands thoroughly with soap and water.
  • Selecting the Injection Site: The typical injection sites are the buttocks or thigh. Rotate injection sites to prevent irritation or tissue damage.
  • Preparing the Injection: Clean the injection site with an alcohol swab and let it dry. Remove the needle cap from the syringe. Draw the prescribed dosage of estradiol valerate into the syringe according to your healthcare provider’s instructions.
  • Administering the Injection:
    • Hold the syringe like a dart at a 90-degree angle to the skin.
    • Quickly insert the needle into the skin at the chosen injection site.
    • Inject the medication slowly and steadily.
    • Once the injection is complete, withdraw the needle swiftly and apply pressure to the injection site with a clean cotton ball or gauze pad.
  • Disposal: Safely dispose of the used needle and syringe in a puncture-proof container as per local regulations.
  • Post-Injection Care: Dispose of used materials properly. Wash your hands thoroughly after handling the injection materials. Monitor for any signs of adverse reactions and report them to your healthcare provider if they occur.
