Can hormone therapy treat night sweats? What the evidence says

Night sweats are one of the most common perimenopausal and menopausal symptoms. As many as 50% of women experience them. As a path to relief, doctors may recommend hormone replacement therapy (HRT) for night sweats—an evidence-based intervention.

Read on to learn why night sweats happen, how HRT can help, and potential risks to be aware of. Wondering if this therapy might be right for you? Chat with your doctor. They’ll assess your full health picture and place you on the right path forward.

Why do night sweats happen during perimenopause?

There’s an area in your brain called the hypothalamus, and one of its main roles is regulating the body’s temperature. When you get hot, the hypothalamus triggers sweating to cool you down. 

Estrogen helps the hypothalamus regulate your temperature. But during perimenopause, hormone levels fluctuate. They no longer regulate the hypothalamus as consistently, and cooling responses might fire when they shouldn’t. This is why many women in perimenopause experience night sweats.

Beyond perimenopause: Other causes to rule out

Night sweats may stem from other causes, such as: 

• Mental health: There are two types of sweat, thermal and emotional. As the names suggest, thermal sweat regulates body temperatures, and emotional sweat is a response to distress. Chronic anxiety and stress can make you sweat more, though this happens less at night.
• Medications: Sweating is a known side effect of a wide range of medications, including antidepressants, diabetes medicine, and asthma inhalers.
• B12 deficiencies: Your central nervous system helps regulate temperature, and it needs enough vitamin B12 to function properly. So, a vitamin B12 deficiency may cause night sweats.
• Cancers: Certain cancers, like lymphoma and leukemia, are linked to night sweats. 

This isn’t an exhaustive list. If you’re experiencing night sweats (regardless of the cause), speak with your doctor about potential solutions.

Does hormone replacement therapy effectively treat night sweats? 

Yes. The American College of Obstetricians & Gynecologists, the Menopause Society, and the FDA all recommend HRT for night sweats. 

According to one review of 21 randomized controlled trials, women on HRT experienced a 77% reduction in night sweats compared with those on the placebo. HRT helps balance changing estrogen levels, which helps the hypothalamus regulate temperature.

What type of HRT is used for night sweats and other menopause symptoms?

There are two main types of HRT: 

• Estrogen therapy (ET) only involves estrogen. On its own, estrogen can cause the uterine lining to thicken abnormally (a condition called endometrial hyperplasia). For this reason, doctors only prescribe ET to people who've had a hysterectomy. 
• Combined estrogen-progesterone therapy (EPT) involves both hormones. Progesterone counteracts estrogen’s effects on the uterine lining, making it safe for anyone with a uterus.

Doctors prescribe both types to help address night sweats. Protecting the uterus is the key reason a physician would choose one over the other. 

Benefits and risks of HRT for night sweats: Make an informed decision

HRT carries both upsides and risks. Below are some common ones, but keep in mind everyone’s experience differs. Talk to your doctor about which risks may apply to you. 

Potential benefits

HRT can help in the following ways:

• Reducing night sweats: By restoring hormonal balance, HRT helps your body regulate its temperature—reducing the frequency and severity of night sweats. 
• Easing hot flashes: Together, estrogen and the hypothalamus regulate your temperature all day, not just at night. This means HRT treats hot flashes, too. 
• Supporting sleep quality: Many women in perimenopause have trouble sleeping, and night sweats are a common cause. By keeping your temperature in check, HRT helps you sleep more restfully.

Potential risks 

In 2025, the FDA removed black box warnings on HRT medications related to breast cancer, cardiovascular disease, and dementia. Originally, these warnings stemmed from research on postmenopausal women using older HRT formulations. Based on updated research, the FDA determined the label was no longer accurate. 

That doesn’t mean modern HRT doesn’t have risks. People taking HRT might experience: 

• Blood clots: In healthy menopausal women, only 1.3 per 10,000 are at risk of developing blood clots. HRT slightly increases that risk, especially in the first year. Women with a history of blood clots are more likely to face this issue. 
• Breast cancer: HRT can modestly increase the risk of breast cancer. For women on EPT, the risk is slightly greater than those on ET. A family history of breast cancer also contributes to heightened risk. 
• Stroke: HRT may slightly increase stroke risks. Doctors consider your cardiovascular health before prescribing. 

Individual experiences vary, so it’s worth discussing them with your provider.

What if HRT isn’t right for you?

If you have a history of any of the following, HRT might not be right for you:

• Breast cancer 
• Liver disease 
• High blood pressure (hypertension)
• Stroke or heart attacks
• Blood clots 
• Chest pain (angina)

This isn’t an exhaustive list, so talk to your doctor about your health history before starting treatment. 

Alternatives to HRT

If HRT isn’t the best way forward, your doctor may recommend an alternative. Here are a few options: 

• Cognitive behavioral therapy (CBT): According to the Menopause Society, CBT is a promising intervention for night sweats. This might be because people start to associate going to bed with sweating. Rather than finding bedtime relaxing, they get anxious and stay up, especially after waking up from night sweats. CBT may help people identify and change these unhelpful thought patterns and so they can fall back asleep after overheating. 
• Bedroom environment changes: While sleeping, try wearing light clothing, keeping your bedroom temperature between 60 and 67 degrees, and using a fan. Night sweats aren’t always a response to the temperature in your room, but you’re more likely to overheat if the thermostat is too high.
• Depression medication: The FDA has approved Brisdelle® (paroxetine) to manage night sweats and other menopause symptoms. Doctors may prescribe other antidepressants off-label to help with hot flashes, too. According to one meta-analysis, women on antidepressants experienced fewer, less intense hot flashes. Between 10–64% of women had noticeable results, depending on the study. 
• Gabapentin: Research suggests that this antiseizure medication helps the hypothalamus regulate your temperature, reducing hot flashes. Gabapentin isn’t FDA approved for this purpose, but doctors may prescribe it off-label.

FAQ

Will night sweats come back when I stop HRT? 

It’s possible. When you discontinue treatment, HRT is no longer helping your body stabilize estrogen levels. The hormonal changes that drive night sweats may return. But for some women, their body has naturally stabilized by the time they stop HRT. 

Which hormones fluctuate during perimenopause? 

Several hormones shift during perimenopause. Fluctuating estrogen levels are a key driver of many perimenopause symptoms, including night sweats. Other hormones that change during this period include progesterone, follicle-stimulating hormone (FSH), and luteinizing hormone (LH). 

Which perimenopause and menopause symptoms does HRT treat? 

HRT treats other symptoms beyond night sweats. These include: 

• Hot flashes 
• Insomnia 
• Mood instability
• Vaginal irritation and dryness
• Urinary urgency

How quickly does HRT work for night sweats?

Experiences vary. Some women start noticing improvement within a few weeks. For others, it may take longer. Your doctor will closely monitor your progress along the way. 

Is a patch or a pill better for night sweats?

According to research published in the Archives of Gynecology and Obstetrics, HRT patches and pills are similarly effective for treating night sweats. But individual responses vary.
