Managing HRT Side Effects

Starting hormone replacement therapy (HRT) can make a real difference to many people's menopause symptoms, but like all medicines, it can come with some potential side effects and risks, too.

While some find that a few mild effects early on in treatment are a fair trade for easing their wider menopause symptoms, others may be wondering if those side effects could end up feeling just as tough as the menopause symptoms themselves.

In this guide, we'll cover everything you need to know about HRT side effects, from the common to the rare, plus some helpful tips on what you can do to manage them.

Three key takeaways

• Most HRT side effects, like headaches, nausea, and breast tenderness, are mild and tend to ease within a few months.
• Oestrogen and progestogen can cause slightly different side effects, so knowing which hormone is in your treatment may help you manage them.
• Serious risks like blood clots and cancer are rare, and for most people under 60, the benefits of HRT outweigh those risks.

Is HRT safe?

Yes, HRT is considered safe for most people. If you're under 60 and start taking it within 10 years of menopause, the benefits (for example, relieving your symptoms and protecting your bones) usually outweigh the risks.

Of course, like with all medications, there is some risk, but your healthcare provider will consider your exact level of risk before offering you HRT.

What are the most common HRT side effects?

When broken down, the side effects of both oestrogen and progestogen are very similar. Common side effects for both oestrogen and progestogen include:

• headaches
• breast pain or tenderness
• nausea
• diarrhoea
• mood changes, including low mood
• mild rash or itching

 

There are, however, some side effects that you may only experience with one type or the other. These are:

Oestrogen side effects	Progestogen side effects
Leg cramps	Feeling tired or dizzy
Unexpected vaginal bleeding or spotting	Changes to your periods
Hair loss	Acne

If you take combined HRT, you might notice symptoms from either list, though these usually improve after a few weeks as your body gets used to the medicine.

Rare HRT side effects

Rare side effects of HRT may include:

• deep vein thrombosis (DVT)
• pulmonary embolism (blood clot in the lungs)
• stroke
• breast cancer (small increased risk with some types of HRT)
• endometrial cancer (if oestrogen is used without a progestogen in those with a womb)
• severe allergic reaction (anaphylaxis)

 

It’s important to remember that although these risks are serious, they’re also very rare. HRT patches, gels, and sprays also carry a lower risk of blood clots than oral tablets do.

If you’re ever worried or unsure, always speak to your GP or prescriber for advice.

6 tips for managing your HRT side effects

Struggling with the side effects of your HRT? Here are six tips that might be able to help:

1. Give it time. Most side effects settle within the first three months, so try to stick with it unless your symptoms are severe.
2. Take oestrogen tablets with food and stick to simple meals if nausea's an issue.
3. Switch to another method if tablets don't suit you. Patches, gels, and sprays don't raise your risk of blood clots in the way tablets can.
4. Apply patches to clean, dry skin below the waist, avoiding your breasts, and rotate the spot each time to reduce any irritation.
5. Try a painkiller like paracetamol or ibuprofen for headaches, and speak to your GP if they last longer than a week.
6. Keep a symptom diary to spot patterns.

 

You should talk to your GP about adjusting your dose or switching to another type of HRT if your side effects haven't improved after three months.

Are there long-term risks to taking HRT?

Any long-term risks of HRT are generally small and depend on the type of HRT, how you take it, and your own personal health history.

Oral oestrogen carries a slightly higher risk of blood clots and stroke than patches, gels, or sprays, which don't raise this risk in the same way.

If you still have a womb, taking oestrogen without a progestogen can thicken the womb lining and increase the risk of endometrial cancer, which is why a progestogen is usually added to the treatment plan for protection.

Does HRT cause cancer?

HRT can slightly increase the risk of some types of cancers, but for most people, the overall risk stays very small.

Combined HRT is linked to around five extra cases of breast cancer in every 1,000 people who take it for five years, while oestrogen-only HRT carries little or no increased risk.

You can reduce your risk of breast cancer by only taking HRT for as long as you need it to control your symptoms.

Those who are currently taking, or have taken HRT in the past, should stay aware of any changes in their breasts and attend routine NHS breast screening when invited.

Are there any side effects to suddenly stopping HRT?

“It's generally safe to stop HRT suddenly, though some people find that their menopause symptoms, like hot flushes, night sweats, or mood changes, return more noticeably than if they'd reduced their dose gradually.

“Whatever your reason, if you’re thinking about coming off HRT, you should chat to your GP or prescriber first. They can help you decide whether to stop outright or taper down slowly.”

Frequently asked questions about HRT side effects

Does HRT cause weight gain?

No, HRT doesn't directly cause weight gain. It can cause temporary bloating or fluid retention in the first few weeks, which some people may mistake for putting on weight, but this usually settles down.

Any weight changes around this time are more likely linked to menopause itself, rather than the hormones in HRT.

Does HRT make you look younger?

HRT isn't an anti-ageing treatment, but it can ease some menopause-related skin changes. Oestrogen plays a role in skin elasticity and collagen production, so some people do notice improvements in their skin texture while on HRT.

Is it better to go through menopause without HRT?

There's no right or wrong answer on whether you should or shouldn’t use HRT during menopause. It depends entirely on your symptoms and what feels right for you.

Some people find that HRT makes a big difference to their quality of life, while others manage well by making lifestyle changes without medication.
