Understanding Bioidentical HRT: Benefits, Risks and What to Ask

Hormonal changes can affect many areas of health and wellbeing. For some people, changes in hormone levels may be associated with symptoms such as hot flushes, night sweats, sleep disturbance, mood changes, vaginal dryness, low libido, irregular periods or other concerns.

Hormone replacement therapy, also known as HRT or menopausal hormone therapy, may be considered by a doctor when symptoms are affecting quality of life. In some situations, a prescriber may also consider a personalised compounded hormone formulation when a commercially available option is not suitable.

At Heywood Compounding, we work with prescribers to prepare personalised compounded medicines when an individualised formulation is required. Our role is to support safe, practical and carefully prepared medication solutions under professional guidance.

What Is Bioidentical HRT?

Bioidentical hormone replacement therapy refers to hormone therapy using hormones that are chemically identical or very similar to hormones naturally produced by the body. These may include hormones such as oestradiol or progesterone, depending on the patient’s needs and the prescriber’s treatment plan.

It is important to understand that the term “bioidentical” can sometimes be confusing. Some commercially available hormone products already contain body-identical hormones. Compounded bioidentical hormone therapy is different because it is prepared by a compounding pharmacy for an individual patient according to a specific prescription.

Compounded hormone therapy may be considered only when the prescriber determines that a personalised formulation is appropriate. It is not automatically safer, more natural or more effective than commercially available hormone therapy.

Why Hormone Therapy May Be Considered

Hormonal changes may occur during perimenopause, menopause, surgical menopause or due to other medical circumstances. Some people may experience symptoms that affect sleep, comfort, mood, concentration, sexual health and daily function.

A doctor may consider hormone therapy after assessing symptoms, medical history, risk factors and treatment goals. The decision should be individualised and reviewed regularly.

Hormone therapy may not be suitable for everyone. A person’s age, personal medical history, family history, cardiovascular risk, cancer history, clotting risk and other medicines may all influence whether hormone therapy is appropriate.

When Compounded HRT May Be Considered

Compounded HRT may be considered when a commercially available product does not meet the patient’s needs. This may include situations where:

• a specific strength is required;

• a different dosage form is needed;

• a patient has difficulty tolerating a commercially available product;

• certain excipients such as colours, flavours, preservatives or fillers need to be avoided;

• a prescriber requires an individualised formulation;

• a temporary alternative is needed due to availability issues, where clinically appropriate.

Compounded medicines are prepared for an individual patient according to a valid prescription. They should only be used under medical supervision and reviewed regularly.

Common Dosage Forms

Depending on the prescription, compounded hormone formulations may be prepared in different forms.

Creams

Creams may be applied to the skin as directed by the prescriber. The choice of base, application site and dose instructions are important and should be followed carefully.

Capsules

Capsules may be prepared when an oral dosage form is prescribed and a specific strength or ingredient combination is required.

Troches

Troches are designed to dissolve slowly in the mouth. They may be prescribed in selected situations depending on the hormone, dose and treatment plan.

Vaginal Preparations

In some cases, prescribers may request a vaginal cream, pessary or other local preparation for specific symptoms. These formulations should be used exactly as directed.

The most suitable dosage form depends on the patient’s symptoms, medical history, hormone being prescribed, absorption considerations, stability and the prescriber’s clinical judgement.

Potential Benefits of a Personalised Approach

When clinically appropriate, compounded hormone formulations may offer practical advantages.

Individualised Strengths

A prescriber may request a specific strength that is not commercially available. This may allow the treatment to be tailored to the patient’s needs.

Alternative Dosage Forms

Some patients may prefer or require a cream, capsule, troche or other dosage form depending on tolerability, convenience or clinical suitability.

Avoidance of Certain Excipients

Where appropriate, selected excipients such as colours, flavours, preservatives or fillers may be avoided.

Personalised Treatment Plan

Compounding allows the prescriber to request a formulation designed for the individual patient. This can be useful when standard options are not suitable.

However, personalised does not mean risk-free. Hormone therapy should always be assessed carefully and monitored by a qualified healthcare professional.

Important Risks and Considerations

Hormone therapy can have risks and side effects. These may vary depending on the type of hormone, dose, route of administration, duration of use and the patient’s individual risk factors.

Possible risks and considerations may include:

• breast tenderness;

• bloating;

• nausea;

• headache;

• mood changes;

• irregular bleeding;

• skin irritation from topical preparations;

• increased risk of blood clots with some hormone therapies;

• breast, endometrial or cardiovascular risk considerations in some patients;

• inadequate endometrial protection if oestrogen therapy is not appropriately balanced in patients with a uterus.

Any unexpected bleeding, new breast symptoms, chest pain, shortness of breath, leg swelling, severe headache or unusual symptoms should be assessed urgently.

Patients should not start, stop or adjust hormone therapy without speaking to their doctor.

Compounded HRT Is Not Suitable for Everyone

Compounded hormone therapy should not be presented as a routine first option when suitable commercially available products exist. In many cases, approved commercial hormone therapies may be preferred because they have been assessed through established regulatory pathways.

Compounded HRT may still have a role in selected cases where a prescriber determines that an individualised formulation is clinically appropriate. This decision should be made carefully, with a clear understanding of the potential benefits, limitations and risks.

The Importance of Medical Review and Monitoring

Before starting hormone therapy, a doctor may consider:

• the patient’s symptoms;

• menstrual and menopause history;

• personal and family medical history;

• breast cancer risk;

• clotting and cardiovascular risk;

• uterus status;

• current medicines;

• previous response to hormone therapy;

• treatment goals;

• the most appropriate dose and dosage form.

Ongoing review is important to assess symptom control, side effects, dose suitability and whether treatment remains appropriate.

Questions to Ask Your Doctor

If you are considering bioidentical or compounded HRT, it may be helpful to ask your doctor:

• What type of hormone therapy is suitable for my symptoms?

• Are there commercially available options that may suit me?

• Why might a compounded formulation be considered in my case?

• What are the benefits and risks for my personal health history?

• Do I need oestrogen, progesterone or another hormone?

• If I have a uterus, how will my endometrium be protected?

• What side effects should I watch for?

• How long should I use this treatment?

• How often should my treatment be reviewed?

• What should I do if I experience bleeding or unusual symptoms?

• Could this interact with my other medicines?

• Are non-hormonal options suitable for me?

These questions can help support a balanced and informed discussion with your healthcare provider.
