Estradiol Besins Pump-pack 750 micrograms/actuation gel – patient leaflet, side effects, dosage

1. What Estradiol Besins is and what it is used for

The full name of your medicine is Estradiol Besins Pump-Pack 750 micrograms/actuation Gel. It is called Estradiol Besins in this leaflet.

Estradiol Besins is a Hormone Replacement Therapy (HRT). It contains the female hormone oestrogen. Estradiol Besins is used in postmenopausal women.

Estradiol Besins is used for:

Relief of symptoms occurring after menopause

During the menopause, the amount of the oestrogen produced by a woman’s body drops. This can cause symptoms such as hot face, neck and chest (“hot flushes”). Estradiol Besins alleviates these symptoms after menopause. You will only be prescribed Estradiol Besins if your symptoms seriously hinder your daily life.

Prevention of osteoporosis

After the menopause some women may develop fragile bones (osteoporosis). You should discuss all available options with your doctor. If you are at an increased risk of fractures due to osteoporosis and other medicines are not suitable for you, you can use Estradiol Besins to prevent osteoporosis after menopause.

How Estradiol Besins works

Estradiol Besins works by replacing the oestrogen in your body. This is so that you have a similar amount of oestrogen as before your menopause.

2. What you need to know before you use Estradiol Besins

This medicine is for external use only and should not therefore be swallowed.

Care should be taken to ensure cleanliness of the skin and hands during application.

Do not apply to damaged skin.

Medical history and regular check-ups

The use of HRT carries risks which need to be considered when deciding whether to start using it, or whether to carry on using it.

The experience in treating women with a premature menopause (due to ovarian failure or surgery) is limited. If you have a premature menopause the risks of using HRT may be different. Please talk to your doctor.

Before you start (or restart) HRT, your doctor will ask you about your own and your family’s medical history. Your doctor may decide to perform a physical examination. This may include an examination of your breasts and/or an internal examination, if necessary.

Once you have started on Estradiol Besins you should see your doctor for regular check-ups (at least once a year). At these check-ups, discuss with your doctor the benefits and risks of continuing with Estradiol Besins.

Go for regular breast screening, as recommended by your doctor.

Do not use Estradiol Besins

If any of the following applies to you. If you are not sure about any of the points below, talk to your doctor before using Estradiol Besins.

Do not use Estradiol Besins:

• If you are allergic (hypersensitive) to estradiol or any other ingredients of this medicine (listed in section 6).
• If you have or have ever had breast cancer, or if you are suspected of having it,

• If you have cancer which is sensitive to oestro-gens, such as cancer of the womb lining

  (endometrium), or if you are suspected of having it,

• If you have any unexplained vaginal bleeding,
• 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 lungs (pulmonary embolism),
• If you have a blood clotting disorder (such as protein C, protein S, or antithrombin deficiency),
• If you have or recently have had a disease caused by blood clots in the arteries, such as a
• Heart attack, stroke or angina,
• If you have or have ever had a liver disease and your liver function tests have not returned to normal,
• If you have a rare blood problem called “porphyria” which is passed down in families (inherited),

If any of the above conditions appear for the first time while using Estradiol Besins, stop using it at once and consult your doctor immediately.

Warnings and precautions

Tell your doctor if you have ever had any of the following problems, before you start the treatment, as these may return or become worse during treatment with Estradiol Besins. If so, you should see your doctor more often for check-ups:

• fibrosis inside your womb,
• growth of womb lining outside your womb (endome-triosis) or a history of excessive growth of the womb lining (endometrial hyperplasia),

• increased risk of developing blood clots (see “Blood clots in a vein (thrombosis)”),

  • increased risk of getting an oestrogen-sensitive cancer (such as having a mother, sister or grandmother who has had breast cancer),
  • high blood pressure,
  • a liver disorder, such as a benign liver tumor,
  • diabetes,
  • gallstones,
  • migraine or severe headaches,
  • a disease of the immune system that affects many organs of the body (Systemic Lupus Erythematosus, SLE),
  • epilepsy,
  • asthma,
  • a disease affecting the eardrum and hearing (otoscle-rosis),
  • a very high level of fat in your blood (triglycerides),
  • fluid retention due to heart or kidney problems.
  • Hereditary and acquired angioedema.

Stop using Estradiol Besins and see a doctor im-mediately.

• If you notice any of the following when taking HRT:
• any of the conditions mentioned in the ‘Do not use Estradiol Besins’ section,
• yellowing of your skin or the whites of your eyes (jaun-dice). These may be signs of a liver disease,
• swollen face, tongue, and/or throat and/or difficulty swallowing or hives, together with difficulty breathing which are suggestive of an angioedema,
• a large rise in your blood pressure (symptoms may be headache, tiredness, dizziness),
• migraine-like headaches which happen for the first time,
• if you become pregnant,

• if you notice signs of a blood clot, such as:

  • painful swelling and redness of the legs,
  • sudden chest pain,
  • difficulty in breathing,

For more information, see ‘Blood clots in a vein (throm-bosis)’.

Note: Estradiol Besins is not a contraceptive. If it is less than 12 months since your last menstrual period or you are under 50 years old, you may still need to use additional contraception to prevent pregnancy. Speak to your doctor for advice.

HRT and cancer

Excessive thickening of the lining of the womb (endometrial hyperplasia) and cancer of the lining of the womb (endometrial cancer)

Using oestrogen-only HRT will increase the risk of excessive thickening of the lining of the womb (endometrial hyperplasia) and cancer of the womb lining (endometrial cancer).

Taking a progestogen in addition to the oestrogen for at least 12 days of each 28 day cycle protects you from this extra risk. So, your doctor will prescribe a progesto-gen separately if you still have your womb. If you have had your womb removed (a hysterectomy), discuss with your doctor whether you can safely take this product without a progestogen.

In women who still have a womb and who are not using HRT, on average, 5 in 1000 will be diagnosed with endometrial cancer between the ages of 50 and 65. For women aged 50 to 65 who still have a womb and who take oestrogen-only HRT, between 10 and 60 women in 1000 will be diagnosed with endometrial cancer (i.e. between 5 and 55 extra cases), depending on the dose and for how long it is taken.

Unexpected bleeding

You will have a bleed once a month (so-called withdrawal bleed) while taking Estradiol Besins. But, if you have unexpected bleeding or drops of blood (spotting) besides your monthly bleeding, which:

• carries on for more than the first 6 months
• starts after you have been using Estradiol Besins for more than 6 months
• carries on after you have stopped using Estradiol Besins

See your doctor as soon as possible.

Breast Cancer

Evidence shows that using combined oestrogen-progestogen or oestrogen-only hormone replacement therapy (HRT) increases the risk of breast cancer. The extra risk depends on how long you use HRT. The additional risk becomes clear within 3 years of use. After stopping HRT the extra risk will decrease with time, but the risk may persist for 10 years or more if you

have used HRT for more than 5 years.

Compare

Women aged 50 to 54 who are not taking HRT, on average, 13 to 17 in 1000 will be diagnosed with breast cancer over a 5-year period.

For women aged 50 who start taking oestrogen-only HRT for 5 years, there will be 16-17 cases in 1000 users (i.e. an extra 0 to 3 cases).

For women aged 50 who start taking oestrogen- progestogen HRT for 5 years, there will be 21 cases in 1000 users (i.e. an extra 4 to 8 cases).

Women aged 50 to 59 who are not taking HRT, on average, 27 in 1000 will be diagnosed with breast cancer over a 10-year period.

For women aged 50 who start taking oestrogen-only HRT for 10 years, there will be 34 cases in 1000 users (i.e. an extra 7 cases)

For women aged 50 who start taking oestrogen- progestogen HRT for 10 years, there will be 48 cases in 1000 users (i.e. an extra 21 cases).

Regularly check your breasts. See your doctor if you notice any changes such as:

• dimpling of the skin
• changes in the nipple
• any lumps you can see or feel

Additionally, you are advised to join mammography screening programs when offered to you. For mammogram screening, it is important that you inform the nurse/healthcare professional who is actually taking the x-ray that you use HRT, as this medication may increase the density of your breasts which may affect the outcome of the mammogram. Where the density of the breast is increased, mammography may not detect all lumps.

Ovarian cancer

Ovarian cancer is rare - much rarer than breast cancer. The use of oestrogen-only or combined oestrogen-progestogen HRT has been associated with a slightly increased risk of ovarian cancer.

The risk of ovarian cancer varies with age. For example, in women aged 50 to 54 who are not taking HRT, about 2 women in 2000 will be diagnosed with ovarian cancer

over a 5-year period. For women who have been using HRT for 5 years, there will be about 3 cases per 2000 users (i.e. about 1 extra case).

Effect of HRT on heart and circulation Blood clots in a vein (thrombosis)

The risk of blood clots in the veins is about 1.3 to 3- times higher in HRT users than in non-users, especially during the first year of using it.

Blood clots can be serious, and if one travels to the lungs, it can cause chest pain, breathlessness, fainting or even death.

You are more likely to get a blood clot in your veins as you get older and if any of the following applies to you. Inform your doctor if any of these situations applies to you:

• you are unable to walk for a long time because of ma-jor surgery, injury or illness (see also section 3, If you need to have surgery),
• you are seriously overweight (BMI >30 kg/m2),
• you have any blood clotting problem that needs long-term treatment with a medicine used to prevent blood clots,
• if any of your close relatives has ever had a blood clot in the leg, lung or another organ,
• you have systemic lupus erythematosus (SLE),
• you have cancer.

For signs of a blood clot, see “Stop using Estradiol Besins and see a doctor immediately”.

Compare

Looking at women in their 50s who are not using HRT, on average, over a 5-year period, 4 to 7 in 1000 would be expected to get a blood clot in a vein.

For women in their 50s who have been using oestrogen-progestogen HRT for over 5 years, there will be 9 to 12 cases in 1000 users (i.e.an extra 5 cases). For women in their 50s who have had their womb removed and have been using oestrogen-only HRT for over 5 years, there will be 5 to 8 cases in 1000 users (i.e. 1 extra case).

Heart disease (heart attack)

There is no evidence that HRT will prevent a heart attack.

Women over the age of 60 years who use oestrogen-progestogen HRT are slightly more likely to develop heart disease than those not using any HRT. For women who have had their womb removed and are using oestrogen-only therapy there is no increased risk of developing a heart disease.

Stroke

The risk of getting stroke is about 1.5 times higher in HRT users than in non-users. The number of extra cases of stroke due to use of HRT will increase with age.

Compare

Looking at women in their 50s who are not using HRT, on average, 8 in 1000 would be expected to have a stroke over a 5-year period. For women in their 50s who are using HRT, there will be 11 cases in 1000 users, over 5 years (i.e. an extra 3 cases).

Children

Estradiol Besins can be accidentally transferred from the skin to other people. Do not allow others, especially children, to come into contact with the exposed area of your skin and cover the area, if needed, after the gel has dried. If a child comes in contact with the area of the skin where Estradiol Besins was applied on, wash the child’s skin with soap and water as soon as possible. Due to the estradiol transfer, young children may show signs of puberty that are not expected (for example breast budding). In most cases the symptoms will disappear when children are no longer exposed to Estradiol Besins.

Contact your healthcare provider if you see any signs and symptoms (breast development or other sexual changes) in a child that may have been exposed accidentally to Estradiol Besins.

Other conditions

HRT will not prevent memory loss. There is some evi-dence of a higher risk of memory loss in women who start using HRT after the age of 65. Speak to your doctor for advice.

MOCKUP Other medicines and Estradiol Besins

Some medicines may interfere with the effect of Estradiol Besins. This might lead to irregular bleeding. This applies to the following medicines:

• Medicines for epilepsy (such as phenobarbital, phenytoin and carbamazepine).
• Medicines for tuberculosis (such as rifampicin, rifabutin).
• Medicines for HIV infection (such as nevirapine, efavirenz, ritonavir and nelfinavir).
• Herbal products containing St John’s wort (Hypericum perforatum).
• HRT can affect the way some other medicines work:
• A medicine for epilepsy (lamotrigine), as this could increase frequency of seizures
• Medicines for Hepatitis C virus (HCV) such as combination regimens ombitasvir/paritaprevir/ritonavir and dasabuvir with or without ribavirin; glecaprevir/ pibrentasvir or sofosbuvir/velpatasvir/voxilaprevir may cause increases in liver function blood test results (increase in ALT liver enzyme) in women using CHCs containing ethinylestradiol. Estradiol Besins lcontains estradiol instead of ethinylestradiol. It is not known whether an increase in ALT liver enzyme can occur when using Estradiol Besins with this HCV combina-tion regimen.
• Skin cleansers and detergents e.g. products containing benzalkonium chloride or sodium lauryl sulphate.

• Other skin products containing alcohol e.g. astringents or sunscreens.

• Products to treat skin and scalp disorders e.g. products to cure warts, acne or dandruff.
• Other skin medications which change how skin is made, e.g. anti-cancer products.

Tell your doctor, pharmacist or nurse if you are using, have recently used or might use any other medicines including medicines obtained without a prescription, herbal medicines or natural products. Your doctor will advise you.

If you believe Estradiol Besins has been transferred to another person (man or child):

Wash the area of skin onto which may have been affected immediately with soap and water.

How you know when your Pump Pack is empty

• The Pump Pack is nearly empty when the plunger does not return back to its original position after you have pushed it down.
• When this happens, do not use the Pump Pack any longer. Start using a new Pump Pack.

If you use more Estradiol Besins than you should

The effects of overdosing are generally: breast tenderness, nausea and vaginal bleeding. These symptoms disappear when treatment is stopped, or the dose is reduced. In case of the accidental use of an excessive dose of the medicine tell your doctor immediately.

If you forget to use Estradiol Besins

• If it is more than 12 hours until your next dose, apply the gel as soon as you remember and apply the next dose at the normal time.
• If it is less than 12 hours until your next dose, skip the missed dose and apply the next dose at the normal time.
• Do not use a double dose (two doses at the same time) to make up for a forgotten dose. If you forget a dose you may have breakthrough bleeding or spotting.

If you need to have surgery

If you are going to have surgery, tell the surgeon that you are using Estradiol Besins. You may need to stop using Estradiol Besins about 4 to 6 weeks before the operation to reduce the risk of a blood clot (see section 2, Blood clots in a vein). Ask your doctor when you can start using Estradiol Besins again.
