Medical history and regular check-ups

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

Go for regular breast screening as recommended by your doctor.

Do not take Indivina

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

Do not take Indivina

• 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 oestrogens, 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 the 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 you are allergic to estradiol valerate or medroxyprogesterone acetate or any of the other ingredients of this medicine (listed in section 6).

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

Warnings and precautions

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

• fibroids inside your womb
• growth of womb lining outside your womb (endometriosis) 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 tumour
• 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 (otosclerosis)
• a very high level of fat in your blood (triglycerides)
• fluid retention due to cardiac or kidney problems
• hereditary and acquired angioedema.

Stop taking Indivina and see a doctor immediately, if you notice any of the following when taking HRT

• any of the conditions mentioned in the “Do not take Indivina” section
• yellowing of your skin or the whites of your eyes (jaundice). 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 (thrombosis)”.

Note: Indivina 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)

Taking 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).

The progestogen in Indivina protects you from this extra risk.

Irregular bleeding

You may have irregular bleeding or drops of blood (spotting) during the first 3-6 months of taking Indivina. However, if the irregular bleeding:

• carries on for more than the first 6 months
• starts after you have been taking Indivina for more than 6 months
• carries on after you have stopped taking Indivina

see your doctor as soon as possible.

Breast cancer

Evidence shows that taking 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-progestagen 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 2,000 will be diagnosed with ovarian cancer over a 5-year period. For women who have been taking HRT for 5 years, there will be about 3 cases per 2,000 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 taking 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 major 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 taking Indivina and see a doctor immediately”.

Compare

Looking at women in their 50s who are not taking HRT, on average, over a 5-year period, 4 to 7 in 1,000 would be expected to get a blood clot in a vein.

For women in their 50s who have been taking oestrogen-progestogen HRT for over 5 years, there will be 9 to 12 cases in 1,000 users (i.e. an extra 5 cases).

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 taking any HRT.

Stroke

The risk of getting a 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 taking HRT, on average, 8 in 1,000 would be expected to have a stroke over a 5-year period. For women in their 50s who are taking HRT, there will be 11 cases in 1,000 users, over 5 years (i.e. an extra 3 cases).

Other conditions

• HRT will not prevent memory loss. There is some evidence of a higher risk of memory loss in women who start using HRT after the age of 65. Speak to your doctor for advice.
• If you are taking thyroid hormone replacement therapy (e.g. thyroxine), your doctor may monitor your thyroid function more often when you start treatment.
• If you have or have had cholasma (yellowish-brown pigmentation patches on the skin, particularly of the face); if so, minimize your exposure to the sun or ultraviolet radiation whilst using Indivina.

Other medicines and Indivina

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

• Medicines for epilepsy (such as phenobarbital, phenytoin and carbamazepin)
• Medicines for tuberculosis (such as rifampicin, rifabutin)
• Medicines for HIV infection (such as nevirapine, efavirenz, ritonavir and nelfinavir)
• Herbal remedies containing St John’s Wort (Hypericum perforatum)
• Medicines for Hepatitis C virus (HCV) (such as combination regimen ombitasvir/paritaprevir/ritonavir with or without dasabuvir as well as a regimen with glecaprevir/pibrentasvir) may cause increases in liver function blood test results (increase in ALT liver enzyme) in women using CHCs containing ethinylestradiol. Indivina contains estradiol instead of ethinylestradiol. It is not known whether an increase in ALT liver enzyme can occur when using Indivina with this HCV combination regimen. Your doctor will advise you.

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines, including medicines obtained without a prescription, herbal medicines or other natural products.

Laboratory tests

If you need a blood test, tell your doctor or the laboratory staff that you are taking Indivina, because this medicine can affect the results of some tests.

Pregnancy and breast-feeding

Indivina is for use in postmenopausal women only. If you become pregnant, stop taking Indivina and contact your doctor.

Driving and using machines

Indivina has no influence on your ability to drive or use machines.

Indivina contains lactose

This medicine contains 78.9 mg (1 mg/2.5 mg tablet), 76.5 mg (1 mg/5 mg tablet) or 75.5 mg (2 mg/5 mg tablet) lactose (as monohydrate). If you have been told by your doctor that you have an intolerance to some sugars, contact your doctor before taking this medicine.

If you take more Indivina than you should

If you or somebody else has taken too many Indivina tablets, talk to your doctor or pharmacist. An overdose of Indivina could make you feel sick, or make you get a headache or uterine bleeding.

If you forget to take Indivina

It is best to take the tablet at the same time each day. Do not take a double dose to make up for a forgotten tablet. You should then continue by taking the next tablet at your usual time. Missing a tablet or irregular use of Indivina tablets may cause breakthrough bleeding or spotting.

If you stop taking Indivina

If you want to stop taking Indivina, talk to your doctor first. He/she will explain the effects of stopping treatment and discuss other possibilities with you.

If you need to have surgery

If you are going to have surgery, tell the surgeon that you are taking Indivina. You may need to stop using Indivina 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 Indivina again.

The following side effects have been reported with other HRTs:

• heart disease (heart attack)
• gall bladder disease
• inflammation of pancreas (pancreatitis)
• skin disorders:
  • yellowish-brown pigmentation patches on the skin, particularly of the face (chloasma)
  • rash with target-shaped reddening or sores (erythema multiforme).
• Probable memory loss over the age of 65
