HRT During Perimenopause

During perimenopause, hormone production varies and menstrual cycles can change. Hot flashes and night sweats may begin while periods remain regular, then continue as cycles become less predictable. You do not need to wait for symptoms to become severe before discussing treatment.

Systemic estrogen can treat hot flashes and night sweats. If you have a uterus, progestogen is usually needed to protect its lining. Low-dose vaginal estrogen may be appropriate when vaginal dryness or pain is the main concern, including when systemic treatment is unnecessary.

An appointment should also review symptoms that may have another cause. Fatigue with heavy bleeding, palpitations with thyroid symptoms, or persistent low mood can need targeted assessment alongside a menopause discussion.

For otherwise healthy people aged 45 or older with typical symptoms and cycle changes, NICE recommends clinical identification of perimenopause without routine hormone testing. A single estradiol or FSH measurement can be difficult to interpret during a fluctuating transition.

Testing has a different role at younger ages or when the history is uncertain. NICE advises considering FSH at ages 40 to 45 with suggestive symptoms, and in suspected premature ovarian insufficiency before 40. Hormonal contraception can make both the bleeding history and hormone tests harder to interpret.

Other tests can answer other questions. A pregnancy test, blood count after heavy bleeding, or thyroid assessment may be appropriate depending on the symptoms. Those tests should follow the clinical history.

A cyclic or sequential regimen usually supplies estrogen throughout the month and progestogen during part of each month. A withdrawal bleed commonly follows the progestogen course. The exact schedule depends on the prescribed preparation.

Your own ovarian activity may still affect bleeding and symptoms, so HRT does not make every cycle predictable. A calendar of bleeding, doses, and symptoms helps the prescriber judge the regimen. Treatment can be reconsidered as the menstrual stage changes.

HRT does not suppress ovulation reliably enough to prevent pregnancy. Irregular or widely spaced periods do not remove the need for contraception when pregnancy remains possible. Explain both menopause symptoms and contraceptive needs at the appointment.

For some women, a suitable hormonal contraceptive can address contraception and some transition symptoms. Others use HRT with a compatible contraceptive method. The combined contraceptive pill is not normally taken alongside systemic HRT; switching requires a prescribed plan.

An intrauterine system may have more than one purpose

A levonorgestrel intrauterine system can provide contraception and help manage heavy bleeding. It is also used for endometrial protection with estrogen in some care plans, but that HRT use is off-label in the United States. The device's suitability and replacement interval need to be reviewed for the specific indication.

Bleeding between periods, after sex, or that becomes unusually heavy or prolonged should be discussed. Perimenopause can change cycles, but the clinician may need to investigate pregnancy, fibroids, the uterine lining, or another cause before deciding how hormones fit.

After starting HRT, distinguish expected withdrawal bleeding from unscheduled bleeding. NICE describes unscheduled bleeding as common during the first six months of systemic treatment, or within three months of a change. Bleeding beyond those periods needs prompt review. Heavy bleeding or bleeding with dizziness, significant weakness, or pain needs earlier assessment.

• Dates of recent periods and a description of any unusual bleeding.
• The symptoms that most affect sleep, work, comfort, or relationships.
• Your contraception, pregnancy plans, medicines, and previous hormone treatment.
• Cancer, clotting, cardiovascular, and liver history, including relevant family diagnoses.

Agree on a written prescription schedule and an initial review, usually around three months. Ask what improvement to expect, which side effects warrant earlier contact, and how to manage missed doses. You should leave knowing how estrogen, uterine protection, and contraception fit together.
