Some medications may not be recommended for you if you have certain factors affecting your health. These are referred to as a drug’s warnings.

Certain people should not take estradiol oral tablet or esterified estrogens/methyltestosterone oral tablet, and others should use either medication with caution.

Boxed warnings for estradiol and esterified estrogens/methyltestosterone

Estradiol and esterified estrogens/methyltestosterone oral tablet have boxed warnings about the risk of certain types of cancer, risk of dementia, and risk of serious heart and blood vessel problems. Boxed warnings are the most serious warnings from the Food and Drug Administration (FDA).

These warnings weren’t specifically reported* in studies of estradiol or esterified estrogens/methyltestosterone. However, these are known risks of estrogen treatment. Both estradiol and esterified estrogens/methyltestosterone contain a form of estrogen.

To learn more about these warnings, read below. You can also talk with your doctor if you have concerns about these risks. They can discuss the risks and benefits of estrogen treatment with you.

Risk of certain types of cancer: According to the Women’s Health Initiative (WHI) study,* Estrogen treatment can increase the risk of certain cancers. These include endometrial (uterine), breast, and ovarian cancers. This risk varies depending on factors such as your health history, and it may increase with long-term use of estrogen. Specifically:

  • Females† with a uterus who take estrogen without progestin have an increased risk of endometrial cancer.(Progestin is a chemical that acts like the progesterone hormone.)
  • Females in postmenopause who take estrogen and progestin have an increased risk of breast cancer.
  • Females who use hormonal therapy to treat menopause symptoms have an increased risk of ovarian cancer.

Talk with your doctor to learn more about the risks of taking estrogen. They’ll help determine your risk based on your health history and other factors specific to you.

Risk of dementia: Treatment with estrogens can increase the risk of dementia in females who are in postmenopause. With dementia, you have problems with thinking, memory, and communication. This effect was reported* in people who used estrogen with medroxyprogesterone acetate, a progestin drug. It’s not known if this risk applies to people who use estrogens alone. It’s also not known if this risk applies when people other than females in postmenopause use estrogens.

Risk of serious heart and blood vessel problems: Treatment with estrogens can increase the risk of serious heart and blood vessel problems. Because of this risk, estrogens should not be used to help prevent heart disease.

Serious heart and blood vessel problems that can occur include heart attack, stroke, and blood clots. Immediately seek emergency medical treatment or call 911 (or a local emergency number) if you have symptoms of a heart attack, stroke, or blood clot.
