Understanding Hormone Replacement Therapy (HRT) Medications
Hormone Replacement Therapy (HRT) is commonly prescribed to manage symptoms of menopause, such as hot flushes, night sweats, mood swings, and vaginal dryness.
There are several types of HRT medications, and the form prescribed depends on your symptoms, health needs, and medical history.
Types of HRT Medications
HRT generally involves replacing the hormones oestrogen and progesterone (or progestogen), which decline naturally during menopause.
The main forms of oestrogen HRT are:
- Transdermal patches - oestrogen only or combined - see below
- Gels
- Oestrogen spray
- Topical Vaginal treatments for local action (creams, pessaries, etc.)
- Oral HRT options - oestrogen only or combined

Micronised progesterone (Utrogestan®) appears lower risk than synthetic types (e.g. norethisterone, medroxyprogesterone).Metabolised by liver, not suitable for some women. - Side effects: mood changes, headaches, bloating, breast tenderness. Slightly increased risk of blood clots (VTE)

How to Choose the Right HRT Medication for You
Choosing the right form of HRT depends on your personal preferences, health considerations, and the severity of your symptoms. Here’s what to consider:
- Personal preferences: Do you prefer a tablet, patch, gel, or vaginal treatment? Are you comfortable with the idea of having something inserted (like a pessary) or prefer a cream you apply?
- Health considerations: Do you have a history of blood clots, liver disease, or other conditions that might affect your treatment? For example, topical vaginal oestrogen may be the safest choice for women with a history of blood clots, as it has minimal systemic effects.
- Symptom severity: If you only need to treat vaginal symptoms, local treatments (creams or pessaries) may be ideal. If you're experiencing more widespread symptoms like hot flushes and mood swings, oral tablets, patches, or gels might be better options.
Key Safety Message
If you have a uterus and are prescribed HRT, you must remain on progestogen alongside oestrogen.
Stopping progestogen is unsafe and increases your risk of womb cancer.
Different types of progestogen carry different risks — including a small increase in breast cancer risk with long‑term use.
Conclusion
There are many different forms of Hormone Replacement Therapy (HRT), and each option has its benefits and potential risks. From oral tablets to transdermal patches, gels, and vaginal treatments, the best choice for you will depend on your symptoms, health status, and personal preferences.
