Elleste Duet Conti tablets are a form of Hormone Replacement Therapy (HRT) designed to alleviate symptoms of menopause in women. Each tablet contains a combination of two hormones: estradiol, a form of oestrogen, and norethisterone, a progestogen. This combination helps manage symptoms like hot flushes, night sweats, mood swings, and vaginal dryness by replenishing hormone levels that naturally decline during menopause. Elleste Duet is also used to prevent osteoporosis in postmenopausal women at risk of fractures. The tablets are taken daily and are suitable for women who have not had a hysterectomy.

What are Elleste Duet Conti tablets?
Elleste Duet Conti tablets are a type of Hormone Replacement Therapy (HRT) that combines two hormones: estradiol, a form of oestrogen, and norethisterone, a type of progestogen. These tablets are designed for women experiencing menopause, helping to alleviate symptoms such as hot flushes, night sweats, mood swings, and vaginal dryness by restoring hormone levels that decrease during this stage of life. Elleste Duet is also used to help prevent osteoporosis in postmenopausal women who are at risk of bone fractures. This medication is suitable for women who still have their wombs and require both oestrogen and progestogen as part of their HRT regimen.
What are the active ingredients in Elleste Duet Conti tablets?
The active ingredients contained in Elleste Duet are: Estradiol (as hemihydrate), norethisterone acetate (combined tablets only).
Elleste Duet Conti tablets also contain the following inactive ingredients to make up the complete product: Lactose monohydrate, maize starch, povidone, talc, magnesium stearate, macrogol 400, titanium dioxide (E171), black iron oxide (E172), hypromellose (E464).
What are Elleste Duet Conti tablets used for?
Elleste Duet Conti is a type of Hormone Replacement Therapy (HRT) that contains two female hormones: an oestrogen (estradiol hemihydrate) and a progestogen (norethisterone acetate).
Elleste Duet Conti is used for:
Relief of menopausal symptoms: During menopause, the body’s production of oestrogen decreases, leading to symptoms such as hot flushes, night sweats, and discomfort. Elleste Duet helps alleviate these symptoms when they significantly impact daily life.
Prevention of osteoporosis: Postmenopausal women are at increased risk of developing osteoporosis, a condition that weakens bones and makes them more prone to fractures. If you are at high risk of fractures and other treatments are not suitable, Elleste Duet 2 mg can be used to help prevent osteoporosis.
How do Elleste Duet Conti tablets work?
Elleste Duet Conti tablets work by supplementing the body with hormones that decrease during menopause.
Estradiol Hemihydrate (Oestrogen): This hormone helps to replace the oestrogen that the ovaries no longer produce after menopause. By restoring oestrogen levels, Elleste Duet helps relieve menopausal symptoms like hot flushes, night sweats, and vaginal dryness.
Norethisterone Acetate (Progestogen): This hormone is included to protect the lining of the womb (endometrium). If oestrogen is taken without progestogen, it can cause the lining of the womb to thicken, increasing the risk of endometrial cancer. Norethisterone balances the effects of oestrogen on the womb, reducing this risk.
Together, these hormones work to manage menopausal symptoms and reduce the risk of osteoporosis while maintaining the health of the womb lining.
How do you use Elleste Duet Conti tablets?
Always take this medication exactly as directed by your doctor or pharmacist. If you are unsure about any instructions, consult with them for clarification.
Your doctor will prescribe the lowest effective dose to treat your symptoms for the shortest duration necessary. If you believe the dosage is too strong or too weak, discuss this with your doctor.
If you are not currently on HRT
If you are not currently taking any hormone replacement therapy (HRT), you can begin taking Elleste Duet Conti Tablets immediately.
Take one tablet daily at a time that works best for you, preferably at the same time each day.
Swallow the tablet whole with water. Each tablet is the same, so there is no need to differentiate.
The days of the week are marked on the blister pack to help you remember to take a tablet each day.
Follow the arrows on the pack and take a tablet daily until the strip is finished.
Start a new strip the day after you finish the previous one.
Switching from another HRT
If you are switching from another HRT and typically have a monthly bleed, start Elleste Duet Conti Tablets on the first day of bleeding. If you do not have a monthly bleed, start Elleste Duet Conti Tablets on any convenient day.
Follow any specific instructions your doctor provides when transitioning from another HRT. If you have any concerns, contact your doctor.
If you need surgery
If you are scheduled for surgery, inform your surgeon that you are taking Elleste Duet Conti Tablets. You may need to stop taking the medication 4 to 6 weeks before the surgery to reduce the risk of blood clots. Consult your doctor on when to resume taking Elleste Duet Conti Tablets after the surgery.
If you forget to take Elleste Duet Conti
If you miss a dose, take the tablet as soon as you remember, then take the next one at your usual time. If you are more than 12 hours late, skip the missed tablet and take the next one at the regular time. Do not double the dose to compensate for a missed one. You may experience breakthrough bleeding or spotting if a dose is missed.

Who should not use Elleste Duet Conti tablets?
Medical history and regular check-ups
Using HRT (Hormone Replacement Therapy) carries certain risks that need to be carefully evaluated when deciding whether to start or continue treatment. If you have experienced premature menopause (due to ovarian failure or surgery), the risks associated with HRT may be different, so it's important to discuss this with your doctor.
Before beginning (or resuming) HRT, your doctor will ask about your personal and family medical history. A physical examination, including a breast exam and possibly an internal examination, may also be recommended.
Once you start taking Elleste Duet, it's important to have regular check-ups with your doctor, at least once a year. During these visits, you should discuss the benefits and risks of continuing with Elleste Duet. Regular breast screenings should also be carried out as recommended by your doctor.
Do not take Elleste Duet Conti
Do not take Elleste Duet Conti if any of the following apply to you. If you are unsure about any of these points, consult your doctor before taking Elleste Duet Conti:
You have or have ever had breast cancer, or it is suspected.
You have cancer that is sensitive to oestrogens, such as cancer of the womb lining (endometrium), or it is suspected.
You have any unexplained vaginal bleeding.
You have untreated excessive thickening of the womb lining (endometrial hyperplasia).
You have or have ever had a blood clot in a vein (thrombosis), such as in the legs (deep venous thrombosis) or lungs (pulmonary embolism).
You have a blood clotting disorder (such as protein C, protein S, or antithrombin deficiency).
You have or have recently had a disease caused by blood clots in the arteries, such as a heart attack, stroke, or angina.
You have or have ever had liver disease, and your liver function tests have not returned to normal.

HRT and cancer: FAQs
Endometrial Hyperplasia and cancer of the womb lining
Taking oestrogen-only Hormone Replacement Therapy (HRT) increases the risk of excessive thickening of the womb lining (endometrial hyperplasia) and cancer of the womb lining (endometrial cancer).To reduce this risk, if you still have your womb, your doctor will prescribe a progestogen to be taken in addition to the oestrogen for at least 12 days of each 28-day cycle. If you have had a hysterectomy (your womb has been removed), discuss with your doctor whether it is safe to take oestrogen-only HRT without adding a progestogen.For women aged 50 to 65 who still have a womb and do not take HRT, about 5 in 1000 will develop endometrial cancer. However, in women of the same age who take oestrogen-only HRT, the number increases to between 10 and 60 in 1000, depending on the dose and duration of treatment.The specific risk of endometrial cancer when using more than 2 mg of Elleste Solo along with a progestogen is currently unknown.
What should I do if I experience unexpected bleeding while on HRT?
If you experience unexpected bleeding or spotting outside of your monthly withdrawal bleed while using Elleste Duet, especially if it:
Persists beyond the first 6 months,
Starts after more than 6 months of use,
Continues after you’ve stopped using Elleste Duet,
You should consult your doctor as soon as possible.
Does HRT increase the risk of breast cancer?
Yes, evidence shows that using combined estrogen-progestogen or estrogen-only HRT increases the risk of breast cancer. This extra risk becomes noticeable within 3 years of use and may persist for 10 years or more after stopping HRT, especially if used for more than 5 years.For example, in women aged 50 to 54 not using HRT, 13 to 17 in 1000 may be diagnosed with breast cancer over a 5-year period. For those on estrogen-only HRT, the risk increases to 16-17 in 1000, and for those on combined HRT, the risk rises to 21 in 1000.
How can I monitor for breast cancer while on HRT?
Regularly check your breasts for any changes such as dimpling of the skin, changes in the nipple, or any lumps you can see or feel. It’s also important to participate in mammography screening programs as advised by your doctor. When having a mammogram, inform the healthcare provider that you are using HRT, as it can increase breast density and affect the mammogram results.
Does HRT increase the risk of ovarian cancer?
There is a slightly increased risk of ovarian cancer with the use of both estrogen-only and combined estrogen-progestogen HRT. For women aged 50 to 54 who are not using HRT, about 2 in 2000 will be diagnosed with ovarian cancer over 5 years. This increases to about 3 in 2000 for women using HRT.
HRT and Circulation: FAQs
How does HRT affect the risk of blood clots?
The risk of blood clots in the veins (thrombosis) is 1.3 to 3 times higher in HRT users compared to non-users, particularly during the first year of use. Blood clots can be serious, especially if they travel to the lungs, potentially causing chest pain, breathlessness, fainting, or even death.In women in their 50s not using HRT, about 4 to 7 in 1000 might develop a blood clot over 5 years. This increases to 9 to 12 in 1000 for women using combined HRT, and to 5 to 8 in 1000 for those using estrogen-only HRT after a hysterectomy.
Does HRT affect heart disease risk?
HRT does not prevent heart attacks. Women over 60 using combined estrogen-progestogen HRT are slightly more likely to develop heart disease compared to non-users. However, for women who have had a hysterectomy and are using estrogen-only therapy, there is no increased risk of heart disease.
Does HRT increase the risk of stroke?
Yes, the risk of stroke is about 1.5 times higher in HRT users compared to non-users. For women in their 50s not using HRT, 8 in 1000 are expected to have a stroke over 5 years. This number increases to 11 in 1000 for those using HRT.
Other FAQs
Does HRT affect memory?
HRT does not prevent memory loss, and there is some evidence that starting HRT after age 65 may increase the risk of memory loss. Consult your doctor for advice.
What should I know about Elleste Duet and pregnancy?
Elleste Duet is intended for use in postmenopausal women only. If you become pregnant, stop using Elleste Duet and contact your doctor.

Do Elleste Duet Conti tablets interact with other medicines?
Certain medications can interfere with the effectiveness of Elleste Duet, potentially leading to irregular bleeding. This includes:
Epilepsy medications (such as phenobarbital, phenytoin, and carbamazepine)
Tuberculosis medications (such as rifampicin and rifabutin)
HIV medications (such as nevirapine, efavirenz, ritonavir, telaprevir, and nelfinavir)
Herbal remedies containing St John’s Wort (Hypericum perforatum)
HRT can also affect how some other medicines work, including:
Lamotrigine (used for epilepsy), as it may increase the frequency of seizures
Hepatitis C virus (HCV) medications (such as combination regimens including ombitasvir/paritaprevir/ritonavir with or without dasabuvir, as well as regimens with glecaprevir/pibrentasvir). These may cause increases in liver enzyme levels (ALT) in women using CHCs containing ethinylestradiol. While Elleste Duet contains estradiol instead of ethinylestradiol, it is unknown whether a similar increase in ALT levels might occur when using Elleste Duet with these HCV treatments.
Always inform your doctor or pharmacist if you are currently taking or have recently taken any other medications, including those obtained without a prescription, herbal remedies, or natural products. Your doctor will provide appropriate guidance.
