Best HRT Options for Perimenopause

For most women in perimenopause, the strongest place to start is bioidentical estradiol through the skin, as a patch or gel, plus micronized progesterone if you still have a uterus. In a year-long placebo-controlled trial of women in the menopause transition or early postmenopause, an estradiol patch plus micronized progesterone helped women fall asleep faster and wake up less often. In the same trial, 17.3% of women on hormones developed clinically significant depressive symptoms, compared with 32.3% on placebo. Estrogen through the skin also has not raised blood clot risk the way pills have. If dryness or painful sex is the problem, low-dose vaginal estrogen is the add-on.

Which HRT works best for perimenopause?

Ask about an estradiol patch or gel first, plus micronized progesterone if you have a uterus. That combination has a year-long perimenopause trial behind it, and skin estrogen carries the lower clot risk.

Hormone therapy itself is the strongest tool you have. The menopause society's 2022 position statement calls it the most effective treatment for hot flashes and night sweats. It is also the most effective treatment for the dryness and urinary changes of menopause, which doctors call genitourinary syndrome of menopause. It has also been shown to prevent bone loss and fractures.

The perimenopause trial is the reason to choose the patch-plus-progesterone combination. Researchers followed 172 women aged 45 to 60 for 12 months. Some wore a 0.1 mg/day estradiol patch and took 200 mg of oral micronized progesterone for 12 days every three months. The others got placebo. The women on hormones fell asleep faster and woke up fewer times in the night. The researchers then accounted for changes in hot flashes and mood, and the sleep gains held. Fewer hot flashes and a better mood did not fully explain the better sleep.

Mood improved too. On the patch plus progesterone, 17.3% of women developed clinically significant depressive symptoms, compared with 32.3% on placebo. The clearest benefit was in women the researchers classed as high-stress. This was a prevention finding in women who were not depressed when the trial started. It does not show that hormones treat depression. The authors present the result as one to act on "if confirmed in future research."

Is the HRT patch better than the pill?

For blood clots, the patch is better. Here is how the main options compare.

In a large US study of insured women aged 50 to 64, estrogen pills carried almost twice the clot risk of patches and other skin forms. Skin estrogen did not raise clot risk compared with taking no hormones at all.

If you do take a pill, the type of estrogen matters. In the same study, pill combinations made with estradiol, the bioidentical form, carried the lowest risk. Combinations with ethinyl estradiol carried the highest risk, followed by those with conjugated equine estrogen.

If you still take the birth control pill or are thinking about it, note this. In that study, combined birth control pills raised clot risk 5.22 times compared with no hormones, and 3.65 times compared with menopause hormone pills.

Skin estrogen may also be kinder to your sex drive. The menopause society says skin forms may be preferable to pills if libido is a concern. Pills raise a protein called sex hormone-binding globulin, which ties up your free testosterone, and skin forms have little effect on it. The patch is low effort. According to the twice-weekly estradiol patch label, you change it every 3 to 4 days.

Do I need progesterone if I take estrogen?

Yes, if you still have a uterus. The estradiol patch label warns that estrogen on its own raises the risk of cancer of the uterine lining in a woman with a uterus. Adding a progestogen has been shown to lower the risk of lining overgrowth, which can come before that cancer.

Micronized progesterone (brand name Prometrium) is the bioidentical option. Its label says it is chemically identical to the progesterone your ovaries make. The capsules contain peanut oil, so you cannot take them if you are allergic to peanuts.

Expect your bleeding to change. In the year-long perimenopause trial, 37% of women on the patch plus progesterone had heavy bleeding, compared with 13% on placebo. Prolonged bleeding affected 15% of women on hormones and 1% on placebo. Tell your clinical team about any bleeding that is new or unusual for you.

What helps vaginal dryness and low libido in perimenopause?

For dryness and painful sex, low-dose vaginal estrogen is the option the menopause society names first. The menopause society recommends it when those symptoms bother you, store-bought products have not helped and you do not need full-body hormones for anything else. Full-body hormone therapy and vaginal estrogen both increase lubrication, blood flow and sensation in vaginal tissue.

One woman on full HRT described the change on Reddit: "now the garage is no longer dry and doesn't hurt when my young 33 year old BF drives his car into it." The top reply came from a woman who had misread her own symptoms: "What I thought was anorgasmia from antidepressants turned out to be the early stages of vaginal atrophy."

Desire works differently. The menopause society says full-body hormone therapy generally does not raise sexual interest, arousal or orgasm beyond what it does by fixing dryness and other menopause symptoms. If sex hurts, estrogen addresses that directly. If the problem is that you do not want sex, tell your clinical team that so your plan targets it.

If you would rather not use estrogen in the vagina, two non-estrogen prescriptions are approved for painful sex after menopause: vaginal DHEA and ospemifene.

How long does HRT take to work, and who can't take it?

Timing varies a lot. The menopause society notes that lower doses, such as a 0.025 mg estradiol patch, may take 6 to 8 weeks to give enough relief. Some women feel a change much sooner. One 57-year-old, already past menopause, posted about her own first week: "My knees aren't hurting anymore! My undercarriage is not itching like poison ivy! I feel BETTER. And I just started HRT less than a week ago!"

Joint relief has trial support too. In trials, including the large Women's Health Initiative (WHI), women on hormone therapy had less joint pain and stiffness than women on placebo. On weight, estrogen plus progestogen either made no difference or came with less weight gain. In the WHI, the difference in weight gain was not statistically significant, but waist size grew less over the first three years than on placebo. Hormone therapy is not a weight-loss treatment, but it does not have to mean a bigger waist.

For women younger than 60, or within 10 years of their last period, who have no reason to avoid it, the menopause society says the benefits outweigh the risks for treating bothersome hot flashes and protecting bone. It also advises checking regularly whether to continue. Hot flashes return in about half of women who stop.

Estrogen is not for everyone. The patch label rules it out if you have unexplained abnormal vaginal bleeding, if you have or have had breast cancer, or if you have an estrogen-sensitive cancer. The label also says estrogen should not be used to prevent heart disease or dementia. You cannot take micronized progesterone if you have had a blood clot, stroke, heart attack or liver disease. Tell your clinical team your full history.

You want to sleep through the night, feel like yourself again and stop sweating through meetings. Take the quiz so your clinical team can review your symptoms and history and decide whether bioidentical estrogen fits your plan.
