1. What Prempak-C is and what it is used for
Prempak-C is a Hormone Replacement Therapy (HRT) preparation containing two types of female hormones, an estrogen and a progestogen (norgestrel). Prempak C is used in menopausal and postmenopausal women.
It is used for:
Relief of symptoms occurring after menopause
During the menopause, the amount of the estrogen produced by a woman’s body drops. This can cause symptoms such as hot face, neck and chest (“hot flushes”). Prempak-C alleviates these symptoms after menopause.
You will only be prescribed Prempak-C 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.
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 Prempak-C 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 Prempak C.
Go for regular breast screening, as recommended by your doctor.
Do not take Prempak-C
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 Prempak-C.
Do not take Prempak-C:
■ If you are allergic (hypersensitive) to
conjugated estrogens or norgestrel or any of the 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 estrogens, such as cancer of the lining of the womb (endometrium) or if you are suspected of having it
■ If you 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 recently had a disease caused by blood clots in the arteries, such as a heart attack, stroke or angina
■ If you have a rare blood problem called “porphyria” which is passed down in families (inherited)
■ 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 previously had liver disease
■ If you are pregnant, or you are breastfeeding.
If any of the above conditions appear for the first time while taking Prempak-C, stop taking it at once and consult your doctor immediately.
Warning and precautions
Talk to your doctor, pharmacist or nurse before taking Prempak-C 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 Prempak-C. 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 section 2.3 - “Blood Clots in a vein (thrombosis)” for more detail)
■ increased risk of getting an estrogen-sensitive cancer (such as having a mother, sister or grandmother who has had breast cancer) (see section 2.2 - HRT and cancer for more detail)
■ high blood pressure
■ heart disease (see section 2.3 - Heart Disease for more detail)
■ a liver disorder (e.g. a benign liver tumour)
■ kidney disease
■ fluid retention due to cardiac or kidney problems
■ diabetes
■ gallbladder disease or gallstones
■ migraine or severe headaches
■ a disease of the immune system that effects many organs of the body (systemic lupus erythematosus, SLE)
■ epilepsy
■ asthma
■ a disease affecting the eardrum and hearing (otosclerosis)
■ low blood calcium levels (hypocalcaemia)
■ a very high level of fat in the blood (triglycerides).
Stop taking Prempak-C 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 Prempak-C’ section
-■ yellowing of your skin or the whites of your eyes (jaundice). These may be signs of a liver disease
■ 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
■ have an allergic reaction, signs of which include rash, itching, shortness of breath, difficulty breathing and a swollen face
■ 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: Prempak-C 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 estrogen-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 Prempak-C protects you from this extra risk.
If you still have your womb, your doctor may prescribe a progestogen as well as estrogen. 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 estrogen without a progestogen.
If you have had your womb removed because of endometriosis, any endometrium left in your body may be at risk. So your doctor may prescribe HRT that includes a progestogen as well as an estrogen.
Your product, Prempak-C, contains a progestogen.
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 estrogen-only HRT, the number will be 2 to 12 times higher, depending on the dose and how long they take it. After stopping treatment risk may remain elevated for at least 10 years. In women with a uterus, use of estrogen-only HRT is not recommended because it increases the risk of endometrial cancer.
The addition of a progestogen to estrogen-only HRT for at least 12 days per cycle can prevent this increased risk.
Irregular bleeding
If you get breakthrough bleeding or spotting,
it’s usually nothing to worry about, especially during the first 3-6 months of taking HRT.
But if the bleeding or spotting:
■ carries on for more than the first 6 months
■ starts after you’ve been on HRT for more than 6 months
■ carries on even after you’ve stopped taking
■ changes in the nipple
■ any lumps you can see or feel
Ovarian Cancer
Ovarian cancer is rare - much rarer than breast cancer, but it is serious. It can be difficult to diagnose, because there are often no obvious signs of the disease.
The use of estrogen-only or combined estrogen-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 taking HRT for 5 years, there will be about 3 cases per 2000 users (i.e. about 1 extra case).
Effects of HRT on your heart or circulation:
Blood Clots in a vein (thrombosis)
The risk of blood clots in the veins (also called deep vein thrombosis, or DVT) is about 1.3 - 3 times higher in HRT users than in nonusers, especially during the first year of taking it.
Compare
Looking at women in their 50s who are not taking 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 are taking estrogen-progestogen HRT for over 5 years, there will be 9 to 12 cases in 1000 users (i.e. an extra
5 cases).
If you’re going to have surgery, make sure your doctor knows about it, or tell the surgeon that you are taking Prempak-C. You may need to stop taking Prempak-C 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 Prempak-C again.
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
> Make an appointment to see your doctor.
It could be a sign that your endometrium has become thicker.
Breast Cancer
Women who have breast cancer, or have had breast cancer in the past, should not take HRT.
Evidence suggests that taking combined estrogen-progestogen and possibly also estrogen-only HRT increases the risk of breast cancer. The extra risk depends on how long you take HRT.
The additional risk becomes clear within a few years. However, it returns to normal within a few years (at most 5) after stopping treatment.
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.
Compare
Women aged 50 to 79 who are not taking HRT, on average, 9 to 14 in 1000 will be diagnosed with breast cancer over a 5-year period. For women aged 50 to 79 who are taking estrogen-progestogen HRT over 5 years, there will be 13 to 20 cases in 1000 users (i.e. an extra 4 to 6 cases).
Regularly check your breasts. See your doctor if you notice any changes, such as:
■ dimpling of the skin
Blood clots can be serious, and 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 in your veins as you get older or if any of the following applies to you. Inform your doctor if any of these situations applies to you:
■ you are seriously overweight (BMI >30 kg/m2)
■ you have had a blood clot before
■ if any of your close family has ever had a blood clot in the leg, lung or another organ
■ you are pregnant or in your postpartum period
■ you have any blood clotting problem that needs treatment with a medicine used to prevent blood clots
■ you are unable to walk for a long time because of major surgery, injury or illness (see also ‘if you’re going to have surgery’ below)
■ you have a rare condition called SLE (systemic lupus erythematosus)
--■ you have cancer
For signs of a blood clot, see “Stop taking Prempak-C and see a doctor immediately”.

There is no evidence that HRT will prevent a heart attack.
Women over the age of 60 who use estrogen-progestogen HRT are slightly more likely to develop heart disease than those not taking any HRT.
If you get:
■ a pain in your chest that spreads to your arm or neck
> See a doctor as soon as possible and do not take any more HRT until your doctor says you can. This pain could be a sign of heart disease.

TRAVEL DIRECTION
Stroke
The risk of having 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.
Other things that can increase the risk of stroke include:
■ 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.
Compare
Looking at women in their 50s who are not taking HRT — on average, over a 5-year period, 8 in 1000 would be expected to have a stroke.
For women in their 50s who are taking HRT, the figure would be 11 cases in 1000 users, over 5 years (i.e. an extra 3 cases).
If you get:
■ unexplained migraine-type headaches, with or without disturbed vision > See a doctor as soon as possible and do not take any more HRT until your doctor says you can. These headaches may be an early warning sign of a stroke.
Other Conditions
HRT will not help 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.
Women with hypertriglyceridemia (high levels of fatty substances in the blood) may experience large increases of their plasma triglycerides, which can lead to inflammation of the pancreas (pancreatitis). Symptoms of pancreatitis include sudden sharp abdominal pains, abdominal swelling, fever and feeling or being sick.
If you are taking thyroid hormone replacement therapy (e.g. thyroxine), your doctor may monitor your thyroid function more often when you start treatment.
HRT may affect some medical tests. If you visit a hospital or clinic for any medical tests, you should tell the doctor concerned that you are taking HRT.
Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines, herbal remedies or other natural products.
Some medicines may interfere with the effect of Prempak-C. This might lead to irregular bleeding.
In particular tell your doctor if you are taking:
■ an anticonvulsant (used to treat epilepsy e.g. phenobarbital, phenytoin, carbamazepine)
■ an anti-infective (e.g. used to treat tuberculosis (rifampicin, rifabutin) or HIV (nevirapine, efavirenz, ritonavir and nelfinavir))
a herbal preparation-suchas Stv John's ’wort" (Hypericum perforatum)
■ metyrapone (most commonly used in the treatment of Cushing's syndrome)
■ aminoglutethimide (most commonly used in the treatment of breast cancer and Cushing's syndrome).
The way that Prempak-C works may be altered if other medicines are used at the same time.
Laboratory tests
If you need a blood test, tell your doctor or the laboratory staff that you are taking Prempak-C, because this medicine can affect the results of some tests.
Pregnancy, breast-feeding and fertility
Prempak-C is for use in postmenopausal women only. You should stop taking Prempak-C and tell your doctor immediately if you know or suspect you are pregnant, or if you are breast-feeding.
Driving and using machines
There is no evidence to suggest that Prempak-C will affect your ability to drive or to operate machinery.
Prempak-C contains lactose monohydrate and sucrose. If you have been told by your doctor that you have an intolerance to some sugars, contact your doctor before taking this medicinal product.
The colouring agent E110 (sunset yellow), that is used in the maroon and yellow tablets, may cause allergic reactions.
Always take this medicine exactly as your doctor or pharmacist has told you. Check with your doctor or pharmacist if you are not sure.
Your doctor will aim to give you the lowest dose for the shortest time to treat your symptoms for as short as necessary. Speak to your doctor if you think this dose is too strong or not strong enough.
Take your tablet at the same time each day as this will help to remind you to take your medicine.
You may start your first pack at any convenient time. However, if you are still having periods you should start on the first day of your next period. If you are transferring from another sequential HRT product, treatment should begin the day following completion of the prior product, unless instructed otherwise by your doctor.
The usual dose is one estrogen tablet every day until Day 16. You should then take one estrogen tablet every day plus one norgestrel tablet every day from days 17-28 as marked on the pack.
Do not leave a break between packs unless your doctor tells you to. Do not stop taking Prempak-C without first discussing it with your doctor.
Instructions for proper use
Start your pack with the tablet marked “Day 1”. You will see that the days of the week have been printed on the top of your pack. Make a hole through the day of the week on which you take your first pill. Pills 8, 15 and 22 will also be taken on this day of the week, so if you are not sure if you have taken your pill(s) you can count backwards, as a reminder.
When you take HRT you will probably have a regular “period” or “withdrawal bleed” each month. This is caused by the hormones, and is perfectly normal. Some women on HRT do not bleed.
This is also quite normal. If you have a bleed at any other time, or bleeding is excessively heavy, please inform your doctor.
Do not try to take off the coating, divide or crush the tablets as this could affect the way Prempak-C works.
If you take more Prempak-C than you should
If you take too many tablets don't worry. You may feel some nausea (sickness), breast tenderness, dizziness, abdominal pain, drowsiness, fatigue or experience a short period of vaginal bleeding, but it is unlikely that serious problems will result. If you are concerned talk to your doctor or pharmacist.
If you forget to take Prempak-C
If you forget to take a tablet don't worry. Take it as soon as you remember and then carry on taking the remaining tablets at the usual time.
If more than one tablet has been forgotten, do not take extra to try to make up for the forgotten tablets.
Missed tablets may cause a short period of light bleeding in women who have not had a hysterectomy.
If you have any further questions on the use of this product, ask your doctor, pharmacist or nurse.
Like all medicines, this medicine can cause side effects, although not everybody gets them.
