FemSeven Patches (50, 75, & 100) information
What are FemSeven Patches and what are they used for?
FemSeven is an HRT treatment patch that delivers a regulated dose of oestrogen to the body. They are available in strengths of 50, 75 & 100. The patches are placed on the skin below the waist where they are worn continuously. They need to be replaced every week. The active ingredient in FemSeven (estradiol hemihydrate) supplements the body’s naturally occurring oestrogen, reducing the negative symptoms many women experience during the menopause.
Unlike some other HRT treatments, FemSeven only contains oestrogen. As such, it is most suitable for women who have had a hysterectomy. Women who have an intact uterus may be on combination treatment, such as Femseven Conti Patches.
Women who have not had a hysterectomy will also need to take a progestogen medicine alongside FemSeven. Oestrogen can cause the womb lining to grow, which in time can cause endometrial cancer. Progestogen medicine inhibits the growth of the womb-lining, reducing - but not eliminating - this risk. If you have had a hysterectomy (womb removal) then endometrial cancer is no longer a risk and you can safely take FemSeven.
Dealing with the menopause: HRT Therapy
Hormone replacement therapy (HRT) is a tried and trusted treatment for women experiencing menopause. During the approach to menopause, women’s bodies produce less and less oestrogen, reducing the levels of oestrogen in the blood. This can cause symptoms that some can find distressing, including hot flushes, night sweats and mood swings. Other typical symptoms include irregular periods and vaginal itchiness and dryness.
By supplementing the body with oestrogen (in FemSeven a form of oestrogen called estradiol hemihydrate), patients are less likely to experience these symptoms. While effective, HRT shouldn’t be considered a long-term treatment. If you’re using HRT to cope with menopausal symptoms, it’s essential that your use is reviewed by a qualified medical professional yearly.
All HRT treatments carry with them risks that you should be aware of. All women using HRT have an increased risk of developing breast cancer. Women using HRT are also at a slightly elevated risk of stroke and of deep-vein thrombosis and pulmonary embolism (blood clots that form in the veins).
Other potential side-effects include menstrual bleeding or spotting, breast pain, depression and changes in mood, an increase in blood pressure and skin problems. (You can find a full list of potential side effects listed here).
Whether to take HRT or not is a personal choice and you should weigh up the risks and benefits. Our Online Doctors can discuss with you the benefits of HRT medicines available.
How estradiol hemihydrate treats menopausal symptoms
Estradiol (also known as E2 or 17β-estradiol) is a naturally occurring hormone that is produced by the human body. Estradiol plays a crucial role in regulating the menstrual cycle and plays a prominent role in hormonally-mediated diseases. In pre-menopausal women, the ovarian follicle secretes between 70 to 500 mcg of estradiol daily into the body. After the menopause, oestrogen in the body is estrone, created by the conversion of androstenedione to estrone by peripheral tissues.
Estradiol is a much more potent form of oestrogen than estrone. The shift from a strong hormone to a weak one (estradiol to estrone) is the cause of menopausal symptoms, including hot flashes, vaginal dryness, mood changes, irregular menses, chills, and sleeping problems.
Supplementing the body’s natural production of oestrogen with estradiol hemihydrate present in FemSeven reduces and in some cases removes the adverse side effects associated with this natural transition.
Is FemSeven right for me?
FemSeven is only available with a prescription. The easiest way to tell if FemSeven is right for you is to get an online assessment; our online assessment normally takes a few minutes to complete. As FemSeven patches are a long-term medication, they need to be currently prescribed by your GP for us to be able to prescribe them to you online.
It’s simple to order FemSeven from our online service by following these steps:
- You’ll need to undertake an online consultation with a qualified professional.
- You’ll also be asked questions about your general health and medications that you may be taking to assess whether FemSeven is safe for you.
- A doctor will review your case and decide whether FemSeven is right for you.
- Your prescription of FemSeven will be dispensed and delivered by post.
Is it safe to buy FemSeven online?
It’s crucial that you only purchase prescription medicines from a UK-registered online pharmacy. Only by buying from a trusted supplier like The Independent Pharmacy can you be confident that the medication you receive is safe and genuine. You should only complete a consultation for a HRT treatment that you are currently prescribed by your doctor.
FemSeven is an oestrogen-only patch that should be applied to the skin once weekly on a continuous basis, i.e. each patch is replaced with a new one after 7 days. Always use FemSeven exactly as your doctor has told you.
Choose a place where there is least wrinkling of the skin and where it will not be rubbed off by clothing, for example on your buttocks, hips or abdomen (avoid the waist).
To remove the FemSeven patch simply lift off one edge and pull. Fold the patch in half (adhesive against adhesive) and throw it away. If the patch starts to come off before 7 days are up, you should take it off completely and apply a new patch.
Replace it when you would normally have done. If you forget to change your patch at the right time, change it as soon as possible, then resume your original schedule. If you still have your womb, breakthrough bleeding is more likely if you forget to change your patch on time.
The active substance is: estradiol hemihydrate.
The other ingredients are: transparent polyethylene terephthalate foil, styrene-isoprene block copolymer and glycerine esters of completely hydrogenated resins.

- If you have excessive thickening of the womb lining (endometrial hyperplasia) that is not being treated.
- If you have or have ever had a blood clot in a vein (thrombosis), such as in the legs (deep venous thrombosis) or in the lungs (pulmonary embolism).

If you need to have surgery
If you are going to have surgery, tell the surgeon that you are using FemSeven. You may need to stop using FemSeven about 4 to 6 weeks before the operation to reduce the risk of a blood clot. Ask your doctor when you can start using FemSeven again.
When to stop using FemSeven
