Part of our guide: Perimenopause treatment: HRT and other options

Maybe a friend swears HRT gave her life back. Maybe you remember the scary headlines from years ago, or your mom was told never to touch it. Now you're in your forties with night sweats, low mood and patchy periods, and you're not sure whether HRT is a sensible option or a risk you shouldn't take.

HRT for perimenopause has changed a lot, and so has our understanding of it. This article explains what HRT is, the different types, the benefits, the risks in context, what to expect when you start, and the questions to ask your doctor, so you can make a decision that's right for you.

The short answer: HRT replaces the estrogen your body is making less of, usually with a progestogen to protect your uterus. It's the most effective treatment for hot flashes and night sweats, and it helps protect your bones. For most women under 60, the benefits outweigh the risks, but the right choice depends on your own health, so it's a decision to make with your doctor.

What HRT is and how it works in perimenopause

HRT (hormone replacement therapy, often called hormone therapy, HT, or menopausal hormone therapy, MHT, in the US) tops up the hormones that fall and fluctuate in perimenopause. You don't have to wait until your periods stop. You can start HRT while you're still having periods if symptoms are affecting your life.

Estrogen. This is the main ingredient that eases symptoms. It comes as patches, gels, sprays or pills. Patches, gels and sprays go through the skin (transdermal), which is associated with a lower risk of blood clots than pills.

Progestogen. If you still have a uterus, you need a progestogen alongside estrogen, because estrogen on its own can thicken the uterine lining and raise the risk of uterine (endometrial) cancer. Options include micronized progesterone capsules (an FDA-approved form that's identical to the hormone your body makes), other progestin pills, or a hormonal IUD, which also provides birth control.

Cyclical or continuous. While you're still having periods, HRT is usually given cyclically, which gives you a regular monthly bleed. Later, many women switch to continuous HRT, which aims for no bleeding.

Vaginal estrogen. Low-dose creams, vaginal inserts or rings placed in the vagina treat vaginal dryness, soreness and some bladder symptoms. Very little is absorbed into the body, and it can be used alongside regular HRT or on its own.

Testosterone. There's no FDA-approved testosterone product for women in the US, but expert guidelines say it can be considered, off-label, for low sex drive that causes distress after menopause. It's usually prescribed by a clinician experienced in menopause care.

HRT isn't one thing. The type, dose and route you choose can change both how well it works and your risks.

Benefits of HRT for perimenopause

For many women, HRT makes a noticeable difference within a few weeks to three months. The main benefits are:

Hot flashes and night sweats. HRT is the most effective treatment for these. Our guide Perimenopause hot flashes: what's happening, and what actually helps compares it with other options.

Sleep. By reducing night sweats, HRT often improves sleep. Our guide Why you're wide awake at 3am in perimenopause explains the link.

Mood. The Menopause Society notes that estrogen may help with depressive symptoms that start in perimenopause. It isn't a treatment for clinical depression. There's more in Perimenopause rage, tears, and everything in between.

Vaginal and bladder symptoms. HRT and vaginal estrogen can ease dryness, discomfort during sex and some urinary symptoms.

Bones. HRT reduces the risk of osteoporosis and fractures while you take it. This benefit fades after stopping.

Many women also report fewer aches and pains and clearer thinking, often because they're sleeping better. The evidence that HRT directly improves memory is mixed, as our article Brain fog is real, and it usually lifts explains.

HRT risks, in context

Every medicine has risks, and HRT's depend on the type you take, your age and your own health. In November 2025, the FDA announced it would remove the broad boxed warnings about heart disease, breast cancer and dementia from hormone therapy labels, while keeping the boxed warning about endometrial cancer for estrogen-only products. The FDA's labeling highlights starting systemic HRT within 10 years of menopause or before age 60. Here's how the main risks look in context.

Breast cancer. Estrogen-only HRT (for women without a uterus) is linked with little or no change in breast cancer risk. Combined HRT (estrogen plus a progestogen) can be linked with a small increased risk, which rises the longer you take it and falls after you stop. Your doctor can explain what this means for someone of your age and history.

Blood clots. HRT taken as pills increases the risk of blood clots. HRT through the skin at standard doses doesn't appear to raise the risk, which is why patches, gels and sprays are often preferred.

Stroke. Oral estrogen is linked with a small increase in stroke risk, but transdermal estrogen isn't. For women under 60, the starting risk of stroke is very low.

Heart disease. HRT doesn't increase the risk of heart disease when started before 60.

Endometrial (uterine) cancer. Taking estrogen without a progestogen raises this risk if you have a uterus. Taking the right progestogen protects against it.

Dementia. HRT shouldn't be taken to prevent dementia, and its effect on dementia risk is still uncertain.

HRT may not be suitable if you've had breast cancer, some types of blood clots, certain liver problems, or unexplained vaginal bleeding. If you have a history of these, you can still talk to your doctor about symptoms, as there are other options and specialist advice is available.

Starting HRT: what to expect

Most women can start HRT through their primary care doctor or OB-GYN. Perimenopause is usually recognized from your age and symptoms, so a hormone blood test often isn't needed. Our article How to talk to your doctor about perimenopause will help you prepare.

Early side effects. Breast tenderness, bloating, headaches, nausea and irregular bleeding are common in the first few weeks. They often settle within three months. If they don't, your doctor can adjust the type or dose.

Follow-up. Many clinicians check in a few months after you start, then at least once a year. Report any bleeding that continues beyond the first three months, or new bleeding after that.

Contraception. HRT isn't birth control. If you're in perimenopause and could get pregnant, you'll need contraception too. A hormonal IUD can do both jobs, providing birth control and the progestogen part of HRT.

How long. There's no fixed time limit. You and your doctor should review the benefits and risks each year and decide together whether to continue.

Cost. What you pay depends on your insurance and the product. Many HRT options are available as generics, so if cost is a barrier, ask your doctor or pharmacist about lower-cost alternatives.

If HRT isn't right for you, there are other options, including FDA-approved non-hormonal medicines for hot flashes and cognitive behavioral therapy.

Frequently asked questions

Can you take HRT during perimenopause?

Yes. You don't have to wait for your periods to stop. HRT can be started in perimenopause if symptoms are affecting your life. While you're still having periods, it's usually given cyclically, which gives you a regular monthly bleed. You'll still need contraception, as HRT doesn't prevent pregnancy. If HRT isn't right for you, see non-hormonal treatments.

Is HRT safe?

For most women under 60, the benefits of HRT outweigh the risks. Risks depend on the type, your age and your health. Patches and gels don't increase blood clot risk at standard doses, and estrogen-only HRT has little or no effect on breast cancer risk. Talk through your own situation with your doctor.

Does HRT increase the risk of breast cancer?

It depends on the type. Estrogen-only HRT is linked with little or no change in breast cancer risk. Combined HRT, which most women with a uterus take, can slightly increase risk, and this rises with longer use and falls after stopping. Your doctor can help you weigh this against your symptoms and other risks.

What are the side effects of HRT?

Common early side effects include breast tenderness, bloating, headaches, nausea and irregular bleeding. These often settle within three months. If they don't, changing the type, dose or way you take HRT usually helps. Report any unexpected or persistent bleeding to your doctor, especially after the first three months.

How long can you stay on HRT?

There's no set time limit. Many women take HRT for several years, and some for longer. Reviewing it with your doctor at least once a year helps check the benefits still outweigh the risks for you. When you decide to stop, you can do so gradually or all at once.
