Oestrogen for HRT

About oestrogen for HRT

Oestrogen is a female hormone that can be used to treat women's health problems including menopausal disorders.

During the menopause or "change", your female hormone levels begin to fall. The menopause normally happens between the ages of 45 and 55, although it can occur earlier or later. HRT (hormone replacement therapy) replaces these hormones. This helps to relieve many of the problems associated with the menopause, such as hot flushes, and protects against osteoporosis (thinning of the bones). However, other treatments for osteoporosis are tried before using HRT to treat this condition.

If you have had your womb removed (hysterectomy) then you only need oestrogen HRT therapy. If however you still have your womb you will be given both oestrogen and progestogen. Please see Oestrogen and Progestogen for HRT for more information.

Different types of oestrogen can be used in HRT products. These can include conjugated oestrogens, estradiol, estriol and estrone.

How to take/use oestrogen for HRT

• Before beginning treatment, read the manufacturer's printed information leaflet.
• Tablets: If you have been prescribed the tablet form, try to take it at the same time each day to avoid missing a dose. If you forget to take your tablet, read the advice on the manufacturer's leaflet and follow the instructions given. If you are not sure what to do ask your pharmacist.
• Patches: If you have been prescribed the patch form, they should be removed after 3-4 days (or once a week in the case of 7-day patches) and replaced with a fresh patch. Do not place the patch on, or near the breast or under the waistband. The patch should be placed on a clean, dry, unbroken area of the skin below the waist. It is recommended the area be changed each time. If the patch falls off in the bath allow the skin to cool before applying a new patch.
• Gel: If you have been prescribed the gel form, apply the required amount of gel to clean, dry, unbroken skin such as the arms, shoulders or inner thighs and allow to dry for five minutes before covering with clothing. Do not apply on or near to the breasts or female genital area. Avoid skin contact with another person, particularly male, and avoid using other skin products or washing the area for at least one hour after application. Wash your hands after applying the gel. If the gel does get onto another person they should wash it off immediately.
