Interactions

Oestrogen is used to help menopause symptoms, such as hot flushes and sleep problems.

Oestrogen usually comes as tablets, patches, gel and spray. Follow the instructions that come with your medicine.

Side effects of oestrogen tablets, patches, gel and spray include headaches, breast pain or breast tenderness. Most serious side effects are rare.

Oestrogen is suitable for most adults, but always check before taking it because it's not suitable for everyone.

Taking oestrogen with other medicines, such as some epilepsy medicines, can cause problems. Always check before taking it.

What oestrogen is for

During menopause, your body starts to make less of a hormone called oestrogen, which can cause symptoms.

Oestrogen is used to help ease menopause symptoms such as:

• hot flushes and night sweats
• vaginal dryness, itching or pain
• sleep problems

If you still have a womb, you will need to use oestrogen along with a hormone called progestogen. This is to help protect your womb lining.

If you've had your womb removed (a hysterectomy), you will not need to use progestogen.

How to take or use oestrogen

Oestrogen comes as tablets, patches, a gel and a spray.

When you use or take oestrogen:

• how you use it, how much and for how long depends on whether you still have regular periods, your symptoms and if you still have a womb
• talk to a doctor if your symptoms are not getting better – it can take time to find the right type and dose to suit you

Always follow your doctor's instructions and the instructions on the leaflet that comes with your medicine.

If you miss a dose of oestrogen

Tablets, spray and gel

If you miss a dose of oestrogen and it's more than 12 hours until your next dose, take or use it as soon as you remember.

If it's less than 12 hours until your next dose, skip the missed dose and take or use the next dose at the normal time.

If you miss a dose, you may have some bleeding or spotting.

Do not take or use 2 doses of your oestrogen to make up for a forgotten dose.

Oestrogen patches

If you forget to change your HRT patch, change it as soon as you remember. Continue the same days that you change your patch.

If you use too much oestrogen

Using too much oestrogen is unlikely to cause problems, but it's important to get medical advice if you take too much as it can sometimes be dangerous. It can also increase the risk of side effects such as breast tenderness, feeling sick (nausea) and vaginal bleeding.

Speak to a pharmacist if:

• you've used or taken more than it says on the packet, leaflet or prescription and it's causing any symptoms

If you're unable to speak to a pharmacist, or you took too much of your medicine on purpose, call NHS 111 for advice.

If you want to carry on using oestrogen, you can usually do so for long as it helps your symptoms.
