Overview

What Is Hormone Therapy?

Hormone therapy is treatment that adds, replaces, blocks, or changes the activity of hormones in the body. Hormone replacement therapy supplies a hormone that is low or no longer produced in sufficient amounts, while hormone-blocking treatment reduces hormone effects or production. The goal depends on the condition being treated, such as relieving selected symptoms, supporting gender-affirming care, or slowing a hormone-sensitive cancer.

Which Conditions It Treats

Which Conditions Does Hormone Therapy Treat?

Hormone therapy may replace hormones when levels are low, including for selected menopause or perimenopause symptoms and other low-estrogen states. It may also change hormone activity to treat some hormone-sensitive cancers or other conditions. The appropriate approach depends on the diagnosis and whether the expected benefits outweigh the risks.

  • Menopause or perimenopause symptoms may be treated with hormone replacement therapy when individualized evaluation supports it.
  • Low-estrogen states may be treated with estrogen therapy when clinically indicated and appropriate for the person’s health history.
  • Gender-affirming hormone care may be prescribed to support a person’s gender-related treatment goals.
  • Selected hormone-sensitive cancers may be treated with medicines that lower hormone levels or block hormone effects.

MEDICAL DECISION

Treatment is based on more than symptoms

Symptoms alone do not establish a need for hormone therapy. Clinicians consider the diagnosis, symptom severity, personal risks, current medicines, and available alternatives before recommending hormone replacement therapy for menopause, low estrogen, or another condition.

Drugs Used

Drugs Used in Hormone Therapy

Medication approachHow it worksCommon clinical useImportant considerations
Hormone replacement medicinesSupply a hormone that the body does not make in adequate amounts.Selected menopause symptoms, low-estrogen states, or other hormone deficiencies.The hormone, dose, route, and need for another hormone depend on the diagnosis and personal risks.
Hormone blockers or antagonistsPrevent a hormone from attaching to or activating its target.Some hormone-sensitive cancers and other condition-specific treatments.The medicine may cause effects related to reduced hormone activity and requires condition-specific monitoring.
Medicines that suppress hormone productionLower the body's production of a particular hormone.Some hormone-sensitive cancers or disorders involving excess hormone activity.Effects, reversibility, bone health, fertility, and other risks vary by medicine and duration.

Depending on the medicine and condition, treatment may be given as tablets, patches, gels, creams, injections, implants, or other formulations. Do not change the dose, route, or schedule of HRT therapy without speaking with the prescriber.

During the Procedure / What to Expect

What to Expect During Hormone Therapy

Before prescribing hormone therapy, the clinician reviews your symptoms, diagnosis, medical history, medicines, allergies, and personal risk factors. Pregnancy, fertility, contraception, or other reproductive considerations may be relevant for some people. The discussion should also cover the intended benefits, alternatives, expected duration, and how the treatment will be monitored.

How Treatment Is Monitored

Follow-up may assess symptom response, side effects, vital signs, examination findings, and condition-specific blood tests or imaging. Depending on the response, the clinician may adjust the dose, change the route, alter the schedule, or recommend another treatment. FDA-approved menopause hormone therapy options should be discussed in the context of your individual needs rather than used without medical guidance.

Risks & Benefits

Benefits and Risks of Hormone Therapy

POTENTIAL BENEFITS

Depending on the regimen, hormone therapy may relieve selected menopause symptoms, replace a needed hormone, support gender-affirming goals, or help control a hormone-sensitive disease. Benefits are specific to the condition and may take time to assess.

POTENTIAL RISKS

Risks vary by the drug, dose, route, duration, age, and underlying condition. Possible harms include troublesome side effects, blood clots, cardiovascular events, and treatment-specific effects on cancer risk or bone health.

  • Breast or pelvic symptoms and changes in bleeding may occur with some regimens.
  • Mood changes, headaches, nausea, or fluid retention can occur depending on the medicine.
  • Some treatments increase the risk of blood clots, which may lead to serious complications.
  • Cardiovascular events are possible with some treatments and may depend on personal risk factors.
  • Some hormone therapies affect bone strength, while others may help protect bone in selected situations.
  • Cancer-related risks or benefits vary by the hormone, diagnosis, and treatment duration.
  • Side effects may affect sexual function, fertility, or other body systems depending on the regimen.

DISCUSS YOUR RISKS

Some conditions need special evaluation

Hormone therapy may be inappropriate or require specialist review in people with certain cancers, unexplained bleeding, clotting disorders, cardiovascular disease, liver disease, or other condition-specific risks. Tell the prescriber about your full medical history before starting treatment.

Recovery

Recovery and Follow-Up

Most people resume their usual activities after taking or receiving hormone medication because there is generally no procedure recovery period. Benefits and side effects may appear over days to months, depending on the regimen, dose, route, and condition. Continue the medicine only as prescribed and do not stop it abruptly unless your clinician advises you to do so.

Ongoing Follow-Up

Scheduled reviews assess whether hormone replacement therapy or another regimen is working, whether side effects are manageable, and whether doses are being taken as directed. Follow-up may include laboratory tests, imaging, or examinations when appropriate. The clinician may continue, adjust, change, or stop treatment based on your response and changing health needs.

When to Call a Doctor

GET URGENT HELP

Recognize emergency symptoms

Seek emergency care for chest pain, sudden shortness of breath, coughing blood, one-sided weakness, trouble speaking, or a sudden severe headache. These symptoms may indicate a serious complication and should not wait for a routine appointment.

  • Contact the treating clinician promptly for heavy or unexpected bleeding.
  • Report a new breast lump or other concerning breast change without delay.
  • Call about severe or persistent side effects that interfere with daily activities.
  • Contact the clinician for redness, swelling, worsening pain, drainage, or other signs of infection at an injection or implant site.
  • Report worsening symptoms or concerns that the treatment is not working as expected.
