Can I Take Fezolinetant Instead of HRT?

You’ve likely seen a lot of buzz about fezolinetant (brand name Veozah or Veoza) in the press recently - but what is it, and is it a suitable alternative to HRT?

Is this an alternative to HRT? The short answer is no.

Fezolinetant may help manage hot flushes and night sweats, but it does not replace the hormones that are lost during menopause. For many women, particularly those in surgical menopause, that distinction is crucial and understanding the difference between these treatments helps ensure women can make informed decisions about their care.

Why the confusion exists

The recent media coverage around fezolinetant has often described it as a “non-hormonal alternative to HRT”, which is snappy and media friendly, but it’s also misleading. 

Fezolinetant and hormone replacement therapy are not doing the same job. Fezolinetant works on a specific pathway in the brain to reduce hot flushes. HRT, by contrast, replaces the hormones the body is no longer producing and has much broader effects across multiple systems.

Presenting these two treatments as interchangeable blurs an important distinction and can leave women unclear about what each option is actually designed to do.

What fezolinetant treats

Fezolinetant is a non-hormonal medication designed to treat vasomotor symptoms of menopause, specifically hot flushes and night sweats.These symptoms are caused by changes in the brain’s temperature regulation system when oestrogen levels fall.

During menopause, certain neurons in the hypothalamus become more sensitive and release a signalling molecule called neurokinin B. This signal can trigger the sudden heat-release response experienced as a hot flush.

Fezolinetant works by blocking the receptor involved in this pathway, known as the neurokinin-3 receptor. By interrupting that signal, it can reduce the frequency and severity of hot flushes.

What it does not do is replace oestrogen.

What HRT treats

Hormone replacement therapy works very differently.

HRT replaces the hormones that the ovaries would normally produce, most importantly oestrogen. In doing so, it addresses both the symptoms of menopause and the underlying hormonal deficiency.

Because of this, HRT can improve a wide range of symptoms associated with menopause, including hot flushes, mood changes, brain fog, vaginal dryness and sleep disruption.

More importantly, oestrogen plays a protective role in several long-term health systems. Restoring hormone levels can help maintain bone density, support cardiovascular health and protect vaginal and urinary tissues.

Why this matters in surgical menopause

Hormone replacement therapy works in a very different way. Rather than just dampening a symptom, it replaces what the body is no longer producing.

HRT restores hormones that the ovaries would normally make, particularly oestrogen. That means it doesn’t just help with visible symptoms, but also addresses the underlying hormonal change driving them. This is why its effects tend to be broader. It can ease hot flushes, but also support mood, sleep, cognitive function, and vaginal health, alongside improving overall quality of life.

There’s also a bigger picture that often gets overlooked. Oestrogen isn’t only about how we feel day to day. It plays an important role in long-term health, helping to maintain bone density, support cardiovascular health, and keep vaginal and urinary tissues healthy.

So while HRT can relieve symptoms, it is also doing something more fundamental. It is replacing a hormone the body needs, with benefits that extend well beyond symptom control.

When fezolinetant may still help

Although it is not a replacement for HRT, fezolinetant can still play an important role for some women, particularly for those who cannot take hormone therapy due to medical reasons. For this group of women – currently estimated to be around 500,000 – the treatment options for severe hot flushes have historically been limited. In this situation, a medication that directly targets the neurological trigger for vasomotor symptoms can offer meaningful relief.

Fezolinetant may also be an option for women who choose not to take hormones and whose primary concern is severe hot flushes.

However, it is important to recognise that the medication addresses one symptom of menopause, not the hormonal change itself.

Not an alternative, but an option for some

Fezolinetant represents an important step forward in menopause care. A non-hormonal medication that directly targets the mechanism behind hot flushes offers a new option for women who previously had very few - but it is not a replacement for hormone therapy.

HRT restores the hormones that menopause removes and helps protect long-term health. Fezolinetant reduces hot flushes by targeting a neurological pathway in the brain.

Both treatments have a place in menopause care. Understanding how they differ allows women to have clearer, more informed conversations with their clinicians about which approach is right for them.
