Your options
- Use GnRH-a to shrink fibroids before surgery, to stop heavy bleeding, or to treat symptoms for a short time before menopause.
- Choose another method to treat uterine fibroids, such as over-the-counter pain medicine, fibroid embolization, birth control pills, or surgery.
This decision aid is for people who have decided to treat their uterine fibroids. Many fibroids do not need treatment.
If you've decided to treat your uterine fibroids, you may also need to make a decision about embolization or a decision about surgery.
If you also have problems with infertility, you may want to try another treatment.
Key points to remember
- Taking gonadotropin-releasing hormone agonists (GnRH-a) puts your body into a state like menopause for as long as you take it. This shrinks fibroids. After you stop taking it, your fibroids may grow back.
- Taking GnRH-a can cause serious side effects, such as bone loss. To limit side effects, you take it for a limited amount of time.
- GnRH-a therapy may be a good choice if you are close to menopause (when fibroids shrink), have heavy bleeding from fibroids, or are planning surgery. This medicine usually is not used to relieve fibroid symptoms only, because fibroids grow back fairly quickly after treatment stops.
- It's possible—but not likely—for you to get pregnant while taking GnRH-a. If you don't want to get pregnant, ask your doctor about birth control.
FAQsWhat are uterine fibroids?
Uterine fibroids are growths in the uterus, Opens dialog. They are not cancer. Fibroids can grow on the inside of the uterus, Opens dialog, in the muscle wall of the uterus, Opens dialog, or on the outer surface of the uterus, Opens dialog. They can change the shape of the uterus as they grow. This can make it hard for you to get pregnant, or it can cause problems during a pregnancy.
Over time, the size, shape, location, and symptoms of fibroids may change.
Uterine fibroids are more common as you age, especially from your 30s and 40s until menopause. Most have mild or no symptoms. But fibroids can cause bad pain, bleeding, and other problems.
The cause of fibroids is not known. But the hormones estrogen, Opens dialog and progesterone, Opens dialog can make them grow. After menopause, when hormone levels decrease, fibroids often shrink or disappear.
When do fibroids need to be treated?
Uterine fibroids usually need treatment when they cause:
- Anemia, Opens dialog from heavy fibroid bleeding.
- Ongoing low back pain or a feeling of pressure in the lower belly.
- Trouble getting pregnant.
- Problems during pregnancy, such as preterm labor.
- Problems with the urinary tract or bowels.
Depending on the reasons you need treatment, one type of treatment may work better for you than another.
How does GnRH-a therapy work?
This medicine puts your body into a state like menopause for as long as you take it. This lowers your body's estrogen. This estrogen decrease:
- Stops menstrual periods.
- Stops the growth of and reduces the size of uterine fibroids.
GnRH-a therapy is not usually used to relieve pain and bleeding only, because fibroids grow back fairly quickly after you stop taking GnRH-a. But it is sometimes used to shrink large fibroids before fibroid surgery or to stop heavy bleeding from fibroids.
For people who are close to menopause (when fibroids will shrink on their own), short-term relief from GnRH-a therapy can be a good choice.
Why might your doctor recommend GnRH-a?
- You have severe bleeding from uterine fibroids and need treatment right away.
- Other treatments for fibroids haven't helped your symptoms, and you're planning surgery later.
- You're close to menopause, when fibroids will get smaller or go away.
- You're planning to have surgery to take out large fibroids.
- You're not planning on getting pregnant soon.

Personal stories about hormone therapy for uterine fibroids
These stories are based on information gathered from health professionals and consumers. They may be helpful as you make important health decisions.
The pain before and during my periods was so bad, I couldn't exercise. I am an active person, and the pain was really getting me down. I have had uterine fibroids for years and have tried ibuprofen and other nonprescription medicines, but they were not helping anymore. When I went to see my doctor about the pain, she said maybe it was time for surgery. I asked if there were any other options, since the last time I had surgery it took me months to recover. I didn't want to go through that again. My doctor said a hormone medicine might help me. She said that it has side effects, so I can't take it for longer than 6 months. That's okay, because menopause is right around the corner for me, and fibroids get better after menopause. After starting the medicine, I did have more hot flashes than usual, but my heavy menstrual bleeding and menstrual pain are almost gone. I think taking this medicine works well for me.
Patricia, age 52
I first noticed that my periods were getting worse about a year ago. I wasn't too concerned, but I discussed the pain with my doctor when I went for a Pap smear. My exam and Pap smear were fine. My doctor said that uterine fibroids could be the cause of my pain. My mom and an older sister have had uterine fibroids, so I thought that must be it. My doctor talked to me about my options. She told me that using birth control pills and ibuprofen would be the best way to start. Now my periods are lighter. And, when I start taking ibuprofen a few days before my period starts, it really helps relieve my pain.
Amy, age 32
I started having really painful menstrual periods about 3 years ago. My doctor asked a lot of questions about my periods and did an exam and some tests. Most of the tests came back normal, but my doctor thought, based on the ultrasound, that uterine fibroids might be the cause of my pain. I tried using a birth control patch for a few months, along with ibuprofen, but it didn't work too well. But it was enough of an improvement to make life tolerable. I really don't want to use any stronger hormone medicine.
Susan, age 37
