1. What Sandrena is and what it is used for
Sandrena is a Hormone Replacement Therapy (HRT). It contains the female hormone oestrogen.
Sandrena 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”). Sandrena alleviates these symptoms after menopause. You will only be prescribed Sandrena if your symptoms seriously hinder your daily life.
You must talk to your doctor if you do not feel better or if you feel worse.
2. What you need to know before you use Sandrena
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 Sandrena 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 Sandrena.
Regularly check your breasts for any changes (see ‘Breast cancer’ below). Go for regular breast screening, as recommended by your doctor.
Do not use Sandrena:
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 Sandrena.
Do not use Sandrena:
- 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 or any of the other ingredients of this medicine Sandrena (listed in section 6).
If any of the above conditions appear for the first time while using Sandrena, stop using it at once and consult your doctor immediately.
Warnings and precautions
Talk to your doctor or pharmacist before using Sandrena. 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 Sandrena. 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 a 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
- migraine or severe headaches
- a disease of the immune system that affects many organs of the body (systemic lupus erythematosus, SLE)
- 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 angioedema.
Stop using Sandrena and see a doctor immediately
If you notice any of the following when taking HRT:
- any of the conditions mentioned in the “Do not use Sandrena” 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
- if you notice signs of a blood clot, such as:
- painful swelling and redness of the legs
- sudden chest pain
- difficulty in breathing
Note: Sandrena 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).
Taking a progestagen in addition to oestrogen for at least 12 days of each 28 day cycle protects you from this extra risk. So your doctor will prescribe a progestagen 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 progestagen.
In women who still have a womb and who are not taking HRT, on average, 5 in 1,000 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 1,000 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.
If your doctor has prescribed you progestagen tablets in addition to Sandrena, you will usually have a bleed once a month (so-called withdrawal bleed). 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 taking Sandrena more than 6 months
- carries on after you have stopped using Sandrena
see your doctor as soon as possible.
Evidence suggests that taking combined oestrogen-progestagen and possibly also oestrogen-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.
For women who have had their womb removed and who are using oestrogen-only HRT for 5 years, little or no increase in breast cancer risk is shown.
Women aged 50 to 79 who are not taking HRT, on average, 9 to 17 in 1,000 will be diagnosed with breast cancer over a 5-year period. For women aged 50 to 79 who are taking oestrogen-progestagen HRT over 5 years, there will be 13 to 23 cases in 1,000 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
- 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 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, 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).
Effects 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 or have had 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 Sandrena and see a doctor immediately”.
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-progestagen HRT for over 5 years, there will be 9 to 12 cases in 1,000 users (i.e. an extra 5 cases).
For women in their 50s who have had their womb removed and have been taking oestrogen-only HRT for over 5 years, there will be 5 to 8 cases in 1,000 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-progestagen HRT are slightly more likely to develop heart disease than those not taking any HRT.
For women who have had their womb removed and are taking oestrogen-only therapy there is no increased risk of developing a heart disease.
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.
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).
- 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.
- Women with a tendency to discoloration of the skin (chloasma) should minimise exposure to the sun or ultraviolet radiation whilst using Sandrena.
Other medicines and Sandrena
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.
Some medicines may interfere with the effect of Sandrena. 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 remedies containing St. John’s wort (Hypericum perforatum).
If you need a blood test, tell your doctor or the laboratory staff that you are using Sandrena, because this medicine can affect the results of some tests.
Pregnancy, breast-feeding and fertility
Sandrena is for use in postmenopausal women only. If you become pregnant, stop using Sandrena and contact your doctor.
Driving and using machines
No studies on the effects of Sandrena on the ability to drive and use machines have been performed.
Sandrena contains propylene glycol
Sandrena contains propylene glycol, which may cause skin irritation.
3. How to use Sandrena
Always use this medicine exactly as your doctor or pharmacist has told you. Check with your doctor or pharmacist if you are not sure.
When to start using Sandrena
You can start using Sandrena straight away if:
- You have never used HRT before
- You are changing over from a period-free HRT.
Wait for your period to end if:
- You are changing over from another type of HRT where you have a period.
If you have not had your womb removed, your doctor will normally also prescribe another medicine containing the hormone progestagen. This is normally a tablet taken for 12 to 14 days in each monthly cycle. After each course of progestagen you will usually have a withdrawal bleed, like a period.
How much to use
Sandrena comes in sachets of 0.5 mg estradiol in 0.5 g of gel, or in sachets of 1 mg estradiol in 1g of gel.
Each pack of Sandrena 0.5 mg gel contains only 0.5 g sachets.
Each pack of Sandrena 1 mg gel contains only 1 g sachets.
Use the amount of Sandrena gel that your doctor has prescribed. Your doctor will aim to prescribe the lowest dose to treat your symptom for as short as necessary. Speak to your doctor if you think this dose is too strong or not strong enough.
- The recommended dose is between 0.5 mg and 1.5 mg of estradiol a day.
- Use the following number of 0.5 g or 1 g sachets depending on the dose, and the pack size prescribed by your doctor:
For a 0.5 mg daily dose: Use one 0.5 g sachet.
For a 1 mg daily dose: There are two options. Use one 1 g sachet or use two 0.5 g sachets.
For a 1.5 mg daily dose: There are two options. Use three 0.5 g sachets or use one 0.5 g sachet with one 1 g sachet.
If you are also taking progestagen tablets, take them as your doctor has told you. You will normally have a withdrawal bleed after each course of progestagen.
How to apply the gel
Sandrena should be rubbed gently on dry and clean skin. It should not be swallowed.
Where to apply the gel
- Do not apply the gel to your breasts, face or on irritated skin.
- Apply the gel to your lower body or thighs.
- Apply the gel to a different side of your body each day.
Follow these instructions:
1. Apply the gel once a day to the skin on your lower body or thighs.
2. Spread the gel over an area 1–2 times the size of your hand.
3. Allow the gel to dry for a few minutes.
4. Wash your hands after applying the gel. Avoid contact of the gel with your eyes. The gel may irritate your eyes.
5. Do not wash the area where you have applied the gel for at least one hour.
If you need to have surgery
If you are going to have surgery, tell the surgeon that you are using Sandrena. You may need to stop using Sandrena 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 Sandrena again.
If you use more Sandrena gel than you should
If you use more gel than you should, talk to your doctor or pharmacist.
You may feel bloated, anxious or irritable, or your breasts may feel tender. Nausea, vomiting and withdrawal bleeding may also occur in some women.
Overdosage is unlikely with transdermal application. Treatment is symptomatic. The gel should be washed. The symptoms disappear when the treatment is stopped or when the dose is reduced.
If you swallow Sandrena
If you swallow Sandrena there is no need to worry. However, you should talk to your doctor.
If you forget to use Sandrena
- Apply the missed dose when you remember, unless you are more than 12 hours late.
- If you are more than 12 hours late just skip the missed dose.
- Missed doses may cause some bleeding between your periods. This is called breakthrough bleeding.
If you stop using Sandrena
Keep using this medicine as prescribed by your doctor. Keep using Sandrena, even if you seem to be better. If you stop too early or too suddenly your problem may return.
If you have any further questions on the use of this medicine, ask your doctor or pharmacist.
