Women's hormonal health conditions are often underdiagnosed, misunderstood, or dismissed for years before effective treatment is offered. Conditions like fibroids, endometriosis, heavy menstrual bleeding, pelvic pain, and hormone-related symptoms can significantly affect quality of life, work, sleep, fertility, mental health, and relationships.
One medication that is gaining increasing attention in women's healthcare is Ryeqo. Despite being available in the UK and Europe, many women still do not know what it is, how it works, or who it may help.

Ryeqo is a prescription medication used to treat:

|
It combines three active ingredients:
|
Relugolix GnRH receptor antagonist |
Estradiol Add-back oestrogen |
Norethisterone acetate Add-back progestogen |
Quick answer
Ryeqo reduces the production of hormones that drive fibroid growth and endometriosis symptoms, while replacing small amounts of hormones to reduce side effects such as bone density loss and menopausal symptoms.
Many women spend years searching for answers before receiving effective treatment for hormone-related conditions. Symptoms are often normalised or dismissed:

Ryeqo belongs to a newer class of medications called GnRH receptor antagonists. These reduce the body's production of oestrogen and progesterone — hormones that can worsen fibroid growth, heavy menstrual bleeding, endometriosis lesions, and pelvic inflammation.
However, completely suppressing oestrogen can trigger menopause-like symptoms. To reduce this risk, Ryeqo includes add-back hormone therapy, which helps maintain safer hormone levels while still controlling symptoms. This combined approach aims to balance:
|

|

|
||
|
|
Uterine fibroids Non-cancerous growths in or around the uterus that can cause heavy periods, anaemia, pelvic pressure, urinary symptoms, pain, and fertility problems. Ryeqo may help shrink fibroid-related symptoms and reduce menstrual bleeding. |
Endometriosis Tissue similar to the uterine lining grows outside the uterus, causing severe pain, fatigue, digestive symptoms, chronic inflammation, and fertility issues. Ryeqo may reduce endometriosis-related pain by lowering oestrogen stimulation. |
Research into GnRH antagonists has expanded rapidly as clinicians search for alternatives to surgery and long-term unmanaged hormonal symptoms.

Wider context: advances in women's hormonal health
|
||
|
Historically, women's health conditions have faced delayed diagnosis, limited research funding, symptom dismissal, under-treatment, and lack of public awareness. Many women with fibroids or endometriosis wait years before diagnosis — affecting physical health, mental wellbeing, career, relationships, and fertility outcomes.
Improving awareness around medications like Ryeqo helps women have more informed conversations with healthcare professionals and explore treatment pathways earlier — before conditions worsen or fertility is compromised.
Depending on the individual and condition being treated, possible benefits may include:
|
Symptom improvements
|
Wider wellbeing

Like all prescription medications, Ryeqo may not be suitable for everyone. Possible side effects can include:

Hormone-modulating medications also require careful medical assessment, particularly in women with certain cardiovascular, liver, clotting, or hormone-sensitive conditions. Treatment decisions should always be personalised and discussed with a qualified healthcare professional.
The growing visibility of medications like Ryeqo reflects a wider shift in women's healthcare — towards earlier intervention, personalised medicine, non-surgical treatment options, and long-term quality of life outcomes.
Women are becoming more proactive about understanding perimenopause, endometriosis, fibroids, hormone regulation, and menopause symptom management. This shift is helping reduce stigma around reproductive and hormonal health conversations — and driving demand for better, faster, more informed care.
Not exactly. Ryeqo is primarily used for fibroids and endometriosis, but because it affects hormone levels, some women experience menopause-like symptom changes while taking it. The add-back hormones in Ryeqo are designed to minimise these effects.
For some women, Ryeqo may significantly reduce or stop menstrual bleeding during treatment. In clinical trials, the majority of women experienced a meaningful reduction in menstrual blood loss within the first few months.
Yes. Ryeqo may help reduce hormone-driven inflammation and pain associated with endometriosis by lowering oestrogen levels. Results vary between individuals, and it should always be prescribed and monitored by a healthcare professional.
No. Ryeqo is not standard HRT, although it contains small amounts of oestrogen and progestogen (add-back therapy) to help reduce side effects from hormone suppression. It works differently from standard HRT and is prescribed for different conditions.
In some cases, Ryeqo may reduce symptoms enough to delay or avoid surgery. Whether it can replace surgery depends on the severity of the condition and individual response, and should be assessed with a specialist.
Women deserve greater awareness, faster diagnosis, and more treatment choices when managing hormonal health conditions. Understanding how medications like Ryeqo work can help you have more informed conversations with healthcare professionals — and explore treatment pathways that align with your symptoms, goals, and overall wellbeing.
