What you should know before using Cyclo-Progynova
As well as benefits, HRT has some risks which you need to consider when you’re deciding whether to take it, or whether to carry on taking it.
Medical Check-ups
Before starting to take hormone replacement therapy you should discuss your personal and family medical history with your doctor.
Your doctor may decide to perform a physical examination of the breasts and/or a pelvic examination before starting this medication - but only if these examinations are necessary for you, or if you have any special concerns.
Once you’ve started on HRT, you should see your doctor for regular check-ups (at least once a year). At these check-ups, your doctor may discuss with you the benefits and risks of continuing to take HRT.
Before starting to take your medicine you must tell your doctor if you have, or have had any of the following as he may decide to alter your treatment or he may ask to see you more often:-
- fibroids in your uterus
- endometriosis (when the lining of the womb grows outside the womb)
- a family history of cancer of the breast or womb
- liver disease
- diabetes
- gall stones
- migraine or severe headaches
- a condition known as systemic lupus erythematosus
- a condition called endometrial hyperplasia (where the lining of the womb grows more than normal)
- epilepsy
- asthma
- deafness (otosclerosis)
- hypertension
- risk factors that indicate you may experience blood clots. These include being seriously overweight, having blood clotting problems or having a blood clot previously. The full list of these risk factors is provided in the section on Blood clotting below.
Be sure to:
-
go for regular breast screening and cervical smear tests
-
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.
Effects On Your Heart or Circulation
Heart Disease
HRT is not recommended for women who have heart disease, or have had heart disease recently. If you have ever had heart disease, talk to your doctor to see if you should be taking HRT.
HRT will not help to prevent heart disease.
Studies with one type of HRT (containing conjugated oestrogen plus the progestogen MPA) have shown that women may be slightly more likely to get heart disease during the first year of taking the medication.
For other types of HRT, the risk is likely to be similar, although this is not yet certain.
If you get:
a pain in your chest that spreads to your arm or neck you must see a doctor as soon as possible. Do not take any more HRT until your doctor says you can. This pain could be a sign of heart disease.
Stroke
Recent research suggests that HRT slightly increases the risk of having a stroke. Other things that can increase the risk of stroke include:
- getting older
- high blood pressure
- smoking
- drinking too much alcohol
- an irregular heartbeat
If you are worried about any of these things,
or if you have had a stroke in the past, talk to your doctor to see if you should take HRT.
Consider the following:
Looking at women in their 50s who are not taking HRT — on average, over a 5-year period, 3 in 1000 would be expected to have a stroke.
For women in their 50s who are taking HRT, the figure would be 4 in 1000.
Looking at women in their 60s who are not taking HRT — on average, over a 5-year period, 11 in 1000 would be expected to have a stroke.
For women in their 60s who are taking HRT, the figure would be 15 in 1000.
If you get
unexplained migraine-type headaches (with or without disturbed vision) you must see a doctor as soon as possible. Do not take any more HRT until your doctor says you can. These headaches may be an early warning sign of a stroke.
Blood Clots
HRT may increase the risk of blood clots in the veins (also called deep vein thrombosis, or DVT), especially during the first year of taking it.
These blood clots are not always serious, but if one travels to the lungs, it can cause chest pain, breathlessness, collapse or even death. This condition is called pulmonary embolism, or PE.
DVT and PE are examples of a condition called venous thromboembolism, or VTE.
You are more likely to get a blood clot:
- if you are seriously overweight
- if you have had a blood clot before
- if any of your close family have had blood clots
- if you have had one or more miscarriages
- if you have any blood clotting problem that needs treatment with a medicine such as warfarin
- if you’re off your feet for a long time because of major surgery, injury or illness
- if you have a rare condition called SLE
If any of these things apply to you, talk to your doctor to see if you should take HRT.
Consider the following:
Looking at women in their 50s who are not taking HRT — on average, over a 5-year period, 3 in 1000 would be expected to get a blood clot.
For women in their 50s who are taking HRT, the figure would be 7 in 1000.
Looking at women in their 60s who are not taking HRT — on average, over a 5-year period, 8 in 1000 would be expected to get a blood clot.
For women in their 60s who are taking HRT, the figure would be 17 in 1000.
If you get any of the following:
- painful swelling in your leg
- sudden chest pain
- difficulty breathing
you must see a doctor as soon as possible. Do not take any more HRT until your doctor says you can. These may be signs of a blood clot.
If you’re going to have surgery, make sure your doctor knows about it. You may need to stop taking HRT about 4 to 6 weeks before the operation, to reduce the risk of a blood clot. Your doctor will tell you when you can start taking HRT again.
Effects on Your Risk of Developing Cancer
Breast Cancer
Women who have breast cancer, or have had breast cancer in the past, should not take HRT
Taking HRT slightly increases the risk of breast cancer; so does having a later menopause. The risk for a post-menopausal woman taking oestrogen-only HRT for 5 years is about the same as for a woman of the same age who’s still having periods over that time and not taking HRT. The risk for a woman who is taking oestrogen plus progestogen HRT is higher than for oestrogen-only HRT (but oestrogen plus progestogen HRT is beneficial for the endometrium, see ‘Endometrial cancer’ below).
For all kinds of HRT, the extra risk of breast cancer goes up the longer you take it, but returns to normal within about 5 years after stopping HRT. Your risk of breast cancer is also higher:
- if you have a close relative (mother, sister or grandmother) who has had breast cancer
- if you are seriously overweight
Consider the following:
Looking at women aged 50 who are not taking HRT – on average 32 in 1000 will have breast cancer diagnosed by the age of 65.
For women who start taking oestrogen-only HRT at age 50 and take it for 5 years, the figure will be between 33 and 34 in 1000 (ie an extra 1-2 cases). If they take oestrogen-only HRT for 10 years, the figure will be 37 in 1000 (i.e. an extra 5 cases).
For women who start taking oestrogen plus progestogen HRT at age 50 and take it for 5 years, the figure will be 38 in 1000 (ie an extra 6 cases). If they take oestrogen plus progestogen HRT for 10 years, the figure will be 51 in 1000 (i.e. an extra 19 cases).
If you notice
any changes in your breast, such as:
- dimpling of the skin
- changes in the nipple
- any lumps you can see or feel
you must make an appointment to see your doctor as soon as possible.
Endometrial cancer (cancer of the lining of the womb)
Taking oestrogen-only HRT for a long time can increase the risk of cancer of the lining of the womb (the endometrium). Taking a progestogen as well as the oestrogen helps to lower the extra risk.
If you still have your womb, your doctor may prescribe a progestogen as well as oestrogen. If so, these may be prescribed separately, or as a combined HRT product.
If you have had your womb removed (a hysterectomy), your doctor will discuss with you whether you can safely take oestrogen without a progestogen.
If you’ve had your womb removed because of endometriosis, any endometrium left in your body may be at risk. If so, your doctor may prescribe HRT that includes a progestogen as well as an oestrogen.
Your product, Cyclo-Progynova 2 mg contains a progestogen.
Consider the following:
Looking at women who still have a uterus and who are not taking HRT – on average 5 in 1000 will be diagnosed with endometrial cancer between the ages of 50 and 65.
For women who take oestrogen-only HRT, the number will be 2 to 12 times higher, depending on the dose and how long you take it.
The addition of a progestogen to oestrogen-only HRT substantially reduces the risk of endometrial cancer.
If you get
breakthrough bleeding or spotting, it’s usually nothing to worry about, especially during the first few months of taking HRT.
But if the bleeding or spotting:
- carries on for more than the first few months
- starts after you’ve been on HRT for a while
- carries on even after you’ve stopped taking HRT
you must make an appointment to see your doctor. It could be a sign that your endometrium has become thicker.
Ovarian cancer
Ovarian cancer (cancer of the ovaries) is very rare, but it is serious.
It can be difficult to diagnose, because there are often no obvious signs of the disease.
Some studies have indicated that taking oestrogen-only HRT for more than 5 years may increase the risk of ovarian cancer. It is not yet known whether other kinds of HRT increase the risk in the same way.
