Question 1

What is Myfembree?

Accepted Answer

Myfembree is a combination medication containing relugolix, estradiol, and norethindrone acetate. It works by modulating the body's hormonal signals, specifically targeting the production of estrogen in the ovaries.

The therapy utilizes a gonadotropin-releasing hormone (GnRH) receptor antagonist alongside supplemental estrogen and progestin. This combination is designed to regulate hormonal activity and maintain a stable physiological environment.

Question 2

What is Myfembree used for?

Accepted Answer

Myfembree is used to treat heavy menstrual bleeding associated with uterine fibroids , as well as moderate to severe pain associated with endometriosis .

Question 3

How does Myfembree work?

Accepted Answer

Mechanism of Action

Myfembree is a combination of three medications that work together to treat symptoms of uterine fibroids and endometriosis. It targets the hormonal triggers that cause these conditions to progress.

Hormone Suppression

The primary ingredient, relugolix, is a gonadotropin-releasing hormone (GnRH) receptor antagonist. It blocks the pituitary gland from releasing the hormones that signal the ovaries to produce estrogen and progesterone. By significantly lowering these hormone levels, the medication helps to:

Reduce the heavy menstrual bleeding caused by uterine fibroids.

Decrease the growth of endometrial tissue, which reduces pelvic pain.

Hormonal Balance

Because suppressing estrogen can lead to side effects like bone thinning and hot flashes, Myfembree includes estradiol and norethindrone acetate. These components provide a small amount of add-back hormone therapy. This helps maintain bone density and manage menopausal-like symptoms while the relugolix continues to treat the underlying condition.

Question 7

What is the dosage of Myfembree and how do I take it?

Accepted Answer

How to Take Myfembree

This medication is taken by mouth once a day. It should be swallowed whole and can be taken with or without food. To help maintain consistent levels in your body, try to take it at the same time every day.

Starting Treatment

Healthcare providers usually recommend starting this medication within the first seven days after your menstrual period begins. If you are switching from another hormonal contraceptive, follow your doctor's specific instructions on when to begin the first dose.

Missed Dose

If you miss a dose, take it as soon as you remember on the same day. If you do not remember until the next day, skip the missed dose entirely and take your next dose at the regular time. Do not take two doses at once to make up for a missed one.

Duration of Use

Because long-term use of this medication can lead to a decrease in bone mineral density, treatment is generally limited to a total duration of 24 months.

Question 8

Is Myfembree safe during pregnancy and breastfeeding?

Accepted Answer

Pregnancy

Myfembree is contraindicated for use during pregnancy because it may cause harm to a developing fetus or lead to early pregnancy loss (miscarriage). Although this medication can change or stop menstrual periods, it is not a form of birth control. It is important to use effective non-hormonal contraception, such as condoms or a copper IUD, while taking Myfembree and for at least one week after the final dose. If you suspect you are pregnant, you should stop taking the medication immediately and contact a healthcare provider.

Breastfeeding

It is not known if the components of Myfembree pass into human breast milk or how they might affect a nursing infant. Because of the potential for serious adverse reactions in a breastfed child, breastfeeding is generally not recommended during treatment with this medication. Patients should discuss the risks and benefits of breastfeeding with their healthcare team to determine the safest approach for their situation.
