If you’ve ever sudden wave of heat, maybe accompanied by a cold sweat, pounding heart, or redness on your chest and face, you know how distracting a hot flash can be. But for some women, they’re more than a rare occurrence. They can keep you awake at night, derail your work, and strike at the worst possible times.
Hot flashes are one of the most common symptoms associated with menopause, and there’s a good explanation for it. During menopause, decreased estrogen levels affect the hypothalamus (the part of the brain that regulates temperature), leading to hot flashes. Those unpredictable waves of heat that can be anything from a slight nuisance to a profoundly debilitating experience.
Because treatment for moderate to severe symptoms can take some trial and error for many women, studies of estradiol may help figure out which treatments are more likely to help, and when to expect improvement.
How Are Hot Flashes Treated?
Everything from lifestyle modifications to prescription drugs can be used to treat hot flashes. The best course of action will depend on the frequency and severity of your hot flashes, as well as your medical history and personal preferences. Be sure to consult with your healthcare provider to determine the best treatment for you.
Lifestyle Approaches
If you are experiencing mild hot flashes, you may be able to alleviate symptoms by implementing some lifestyle changes. Many healthcare providers will recommend keeping cool by dressing in layers, avoiding hot flash triggers such as spicy foods, caffeine, and alcohol, and engaging in stress reducing activities like slow, deep breathing or meditation.
In addition, not smoking and weight loss may help reduce the frequency of hot flashes in women who are overweight or obese.
Mind Body Therapies
Some women may find relief from hot flashes by utilizing mind body interventions such as cognitive behavioral therapy (CBT) or hypnosis. CBT can help decrease the disruption caused by hot flashes and night sweats. Hypnosis may also be beneficial in reducing the frequency and severity of hot flashes, according to some studies.
Acupuncture is another intervention that has been studied, though results are mixed. Some studies suggest acupuncture may decrease the frequency of hot flashes, while others have found no benefit.
Hormone Therapy
When it comes to moderate to severe hot flashes, estrogen is the primary medication used to treat it. For women with an intact uterus, estrogen is typically prescribed in combination with a progesterone to protect the uterus.
As with any medication, be sure to use the lowest dose for the shortest amount of time necessary to alleviate your symptoms. One commonly prescribed estrogen medication for hot flashes is 17beta estradiol. There is extensive research on the efficacy and onset of action of this medication.
What is Estradiol and Why Does it Work?
17beta estradiol is a type of estrogen that's chemically identical to the estrogen that your body makes. One way menopause messes with you is that when your estrogen levels drop, your body's thermostat (which is controlled by estrogen) gets all out of whack, leading to hot flashes.
Hence the logic behind estradiol. Replacing the missing estrogen in the body means that it will once again be able to effectively regulate temperature in the body. So it’s no wonder that it can decrease hot flash frequency and intensity.
Decades old, it’s often prescribed as a first line defense against moderate to severe vasomotor symptoms of menopause.
Estradiol at 1 mg: What a 12 Week Clinical Trial Revealed
In a clinical trial that studied the efficacy of oral 17beta estradiol, varying doses were tested for their impact on moderate-to-severe hot flashes over a period of 12 weeks. The data from this study can provide helpful insight into the use of this medication.
At 4 weeks, 86% of women receiving 1 mg of estradiol had at least a 50% reduction in moderate to severe hot flashes, compared with 50% of placebo treated women. The 1 mg dose gave statistically significant hot flash reduction as early as 4 weeks. The lower doses took longer to show significant separation from placebo.
The study also tested a higher 2 mg dose, which worked just as well. But twice as many women in the 2 mg group stopped taking the drug because of side effects. So the researchers determined that 1 mg seemed to be the most practical starting dose. It provided relief, but was easier to tolerate.
Significant improvement in hot flashes can be seen as early as two weeks, with continued benefits observed through 12 weeks of treatment.
Common Side Effects
Estradiol, like all drugs, may produce side effects. Side effects of oral estradiol include: breast tenderness, bloating, nausea and headaches. As this study demonstrated, side effects may be dose dependent, with more side effects occurring in higher doses. Side effects are often mild and may dissipate over time.
Your provider can help you weigh the potential benefits and side effects based on your individual situation.
FAQs
Is estradiol FDA approved for menopause symptoms? Yes. Several estradiol products are approved by the FDA to treat moderate to severe vasomotor symptoms (hot flashes) due to menopause.
Do I need to take progesterone too? If you have a uterus, it is advisable to use progesterone in addition to estrogen to prevent overgrowth of the uterine lining. Your health care provider will decide what is best for you and your individual medical situation.
How long until I see results? In this study, hot flashes started getting better at 2 weeks and were still improving at 12 weeks. The amount of improvement will depend on you and your body. Your healthcare provider can help you figure out what to expect.
Who shouldn’t take estradiol? If you’ve had conditions like estrogen dependent cancers (e.g., breast cancer), blood clots, pregnancy, high blood pressure (HTN) or liver disease, you likely won’t be a candidate for hormone replacement. Your provider will review your medical history before recommending this medication.
How long would I use it? The goal is to take the lowest effective dose for the shortest amount of time. How that is will be something your provider can talk to you about. You should speak with your provider about your individual needs.
What if I can't take hormone therapy? There are non hormonal prescription options that may help, including low dose antidepressants and other medications. The right approach depends on your health history and the severity of your symptoms. This is something to discuss in detail with your healthcare provider.
