Estradot is a continuous oestrogen alone hormone replacement therapy (HRT), containing a naturally occurring form of the female hormone oestrogen, estradiol hemihydrate. Estradot comes in the form of a circular patch, which comes in different sizes depending on the strength of the hormone. The patches release the estradiol through the skin into the bloodstream at a constant rate and are changed twice per week.
This type of HRT is most suitable for you if you who have had a hysterectomy (removal of the uterus or womb). If you have not had a hysterectomy, you should also take another hormone called progestin whilst taking HRT, to prevent complications associated with taking oestrogen alone.
The estradiol helps to make up for the body’s reduced levels of oestrogen. Offsetting this balance will help to:
- Provide relief of the symptoms that occur after the menopause, such as hot flushes.
- Prevent osteoporosis (fragile bones) which can develop after menopause. Falling levels of oestrogen can promote thinning of the bones and make them more prone to breaking. Supplementing the oestrogen can help to prevent bone loss and fractures, which can occur in women in the years following menopause.
Apply a new patch twice a week (every three to four days) to your buttock or hip, below the waistline. It is best to avoid areas where clothing can cause the patch to rub off.
Do not apply the patch to or near to the breasts.
Each time you apply a new patch, change the site you place it and do not place the patch on that same area for at least a week.
Before you apply the patch to your skin, make sure that your skin is clean and dry, cool, free of any powder, oily moisturise or lotion and free of cuts or irritation.
You can keep the patch on when you have a shower or bath. If the patch falls off, wait until the skin is dry and at a normal temperature before applying a new patch. Replace the patch with a new one immediately. Replace this patch on the scheduled ‘change’ day.
For details on applying the patch, please see the product information leaflet.
Please note: if you ever need to have major surgery, please inform us as soon as you know, so that our doctor can advise you on whether to stop taking this medication.
Your need for HRT should be reviewed by your doctor at least once every twelve months.
