Menopausal hormone therapy (MHT) - patch

What does it do?

As you go through menopause, you produce less of the hormone oestrogen. MHT patches contain oestrogen, which treats symptoms of menopause and helps prevent weak bones (osteoporosis). If you still have your uterus (womb), you need to take progestogen as well to protect the lining of your uterus.

How should you use it?

Apply the patch to a clean, dry area of skin (such as the tummy) as directed. When you have removed the old patch, apply the new one in a different place to prevent irritating your skin. Do not cut the patch.

What if you forget a dose?

If you forget to change the patch, remove the old patch and apply a new one as soon as possible.

Can you take other medicines?

Tell your pharmacist or doctor about all medicines or treatments that you may be taking, including vitamins, herbal products (e.g. St John's wort) or recreational drugs.
