What the medication is used for
Sandoz Estradiol Derm is approved for use in the following situations:
- The Relief of Menopausal and Postmenopausal Symptoms
To Prevent Osteoporosis
Some women are more likely to develop osteoporosis after menopause than others. You should discuss risk factors for osteoporosis with your doctor.If you have been prescribed Sandoz Estradiol Derm only for the prevention of osteoporosis you should discuss other therapies with your doctor.
In addition, you should discuss adequate diet, calcium and vitamin D intake, cessation of smoking and regular physical weight-bearing exercise with your doctor or pharmacist.
Uses of Progestins
If you have not had a hysterectomy (surgical removal of the uterus), estrogens should be prescribed in association with a progestin medication.
Sandoz Estradiol Derm should be used only under the supervision of a doctor, with regular follow-up at least once a year to identify side effects associated with its use. Your first follow-up visit should be within 3 to 6 months of starting treatment. Your visit may include a blood pressure check, a breast exam, a Pap smear and pelvic exam. You should have a mammogram before starting treatment and at regular intervals as recommended by your doctor. Your doctor may recommend some blood tests.
You should carefully discuss the risks and benefits of hormone replacement therapy (HRT) with your doctor. You should regularly talk with your doctor about whether you still need treatment with HRT.
What it does
Sandoz Estradiol Derm (estradiol-17β) is a type of treatment known as hormone replacement therapy (HRT). Sandoz Estradiol Derm is a patch which contains the estrogen hormone, estradiol. Estradiol is an estrogen produced by your ovaries before menopause (the end of monthly menstrual periods).
When applied to the skin, the Sandoz Estradiol Derm patch continually releases small, controlled quantities of estradiol, which pass through your skin and into your bloodstream
Your body normally makes estrogens and progestins (female hormones) mainly in the ovaries. Between ages 45 and 55, the ovaries gradually stop making estrogens. This leads to a decrease in body estrogen levels and a natural menopause (the end of monthly menstrual periods). If both ovaries are removed during an operation before natural menopause takes place, the sudden decrease in estrogen levels causes surgical menopause.
Menopause is not a disease; it is a natural life event and different women experience menopause and its symptoms differently. Not all women suffer obvious symptoms of estrogen deficiency. When the estrogen levels begin decreasing, some women develop very uncomfortable symptoms, such as feelings of warmth in the face, neck, and chest, or sudden intense episodes of heat and sweating (hot flashes or hot flushes). Using estrogen drugs can help the body adjust to lower estrogen levels and reduce these symptoms.
Osteoporosis is a thinning of the bones that makes them weaker and allows them to break more easily. In osteoporosis, the bones of the spine, wrists and hips break most often. The bones of both men and women start to thin after about age 40, but women lose bone faster after menopause. Using estrogens after menopause slows down bone thinning and may prevent bones from breaking.
When it should not be used
Sandoz Estradiol Derm (estradiol-17β) should not be used if you:
- have active liver disease.
- have a personal history of or currently have breast cancer or endometrial cancer (cancer of the uterus) or any other cancer which is sensitive to estrogens.
- have been diagnosed with endometrial hyperplasia (overgrowth of the lining of the uterus).
- have experienced undiagnosed or unexpected genital bleeding.
- have been diagnosed with porphyria (a disease of blood pigment).
- are pregnant or suspect you may be pregnant (Since pregnancy may be possible early in menopause while you are still having spontaneous periods, the use of non-hormonal birth control should be discussed with your doctor at this time. If you take estrogen during pregnancy, there is a small risk of your unborn child having birth defects.)
- are breast feeding.
- have a history of coronary heart disease (including heart attack) or stroke.
- experience migraine headaches.
- have a history of or currently have blood clots.
- have active thrombophlebitis (inflammation of the veins).

Warnings and precautions
Serious Warnings and Precautions
The Women’s Health Initiative (WHI) trial is a large clinical study that assessed the benefits and risks of oral combined estrogen plus progestin therapy and oral estrogen-alone therapy compared with placebo (a pill with no active ingredients) in postmenopausal women. The WHI trial indicated an increased risk of myocardial infarction (heart attack), stroke, breast cancer, pulmonary emboli (blood clots in the lungs) and deep vein thrombosis (blood clots in the large veins) in postmenopausal women taking oral combined estrogen plus progestin. The WHI trial indicated an increased risk of stroke and deep vein thrombosis in postmenopausal women with prior hysterectomy (surgical removal of the uterus) taking oral estrogen-alone.
Therefore, you should highly consider the following:
- There is an increased risk of developing invasive breast cancer, heart attack, stroke and blood clots in both lungs and large veins with the use of estrogen plus progestin therapy.
- There is an increased risk of stroke and blood clots in the large veins with the use of estrogen-alone therapy.
- Estrogens with or without progestins should not be used for the prevention of heart disease or stroke.
- Estrogens with or without progestins should be used at the lowest effective dose and for the shortest period of time possible. Regular medical follow-up is advised.
Breast Cancer
The results of the Women’s Health Initiative (WHI) trial indicated no difference in the risk of breast cancer in post-menopausal women with prior hysterectomy taking oral estrogen-alone compared to women taking placebo. Estrogens should not be taken by women who have a personal history of breast cancer. In addition, women with a family history of breast cancer or women with a history of breast lumps, breast biopsies or abnormal mammograms (breast x-rays) should consult with their doctor before starting hormone replacement therapy (HRT). Women should have a mammogram before starting HRT and at regular intervals during treatment as recommended by their doctor.
Regular breast examinations by a doctor are recommended for all women. You should review technique for breast self-examination with your doctor.
Overgrowth of the Lining of the Uterus and Cancer of the Uterus
The use of estrogen-alone therapy by postmenopausal
women who still have a uterus increases
the risk of developing endometrial hyperplasia
(overgrowth of the lining of the uterus), which
increases the risk of endometrial cancer (cancer of
the lining of the uterus). If you still have your uterus,
you should take a progestin medication (another
hormone drug) regularly for a certain number of days
of each month to reduce the risk of endometrial
hyperplasia.
You should discuss progestin therapy and risk factors
for endometrial hyperplasia and endometrial
carcinoma with your doctor. It is important to report
any unusual vaginal bleeding to your doctor right
away while you are using ESTRING. Vaginal
bleeding after menopause may be a warning sign of
cancer of the uterus (womb). Your doctor should
check any unusual vaginal bleeding to find out the
cause.
If you have had your uterus removed, you are not at
risk of developing endometrial hyperplasia
or endometrial carcinoma. Progestin therapy is
therefore not generally required in women who
have had a hysterectomy.
Ovarian Cancer
Use of oral estrogen alone and estrogen plus progestin therapies for 5 or more years has been associated with a small increased risk of ovarian cancer.
Heart Disease and Stroke
The results of the WHI trial indicated an increased risk of stroke and coronary heart disease in postmenopausal women taking combined oral estrogen plus progestin compared to women taking placebo.
The results of the WHI trial indicated an increased risk of stroke, but no difference in the risk of coronary heart disease in post-menopausal women with prior hysterectomy taking oral estrogen-alone compared to women taking placebo.
Abnormal Blood Clotting
The results of the WHI trial indicated an increased risk of blood clots in the lungs and large veins in postmenopausal women taking combined estrogen plus progestin compared to women taking placebo.
The results of the WHI trial indicated an increased risk of blood clots in the large veins, but no difference in the risk of blood clots in the lungs in postmenopausal women with prior hysterectomy taking estrogen-alone compared to women taking placebo.
The risk of blood clots also increases with age, if you or a family member has had blood clots, if you smoke or if you are severely overweight. The risk of blood clots is also temporarily increased if you are immobilized for long periods of time and with major surgery. You should discuss risk factors for blood clots with your doctor since blood clots can be lifethreatening or cause serious disability.
Gallbladder Disease
The use of oral estrogens by post-menopausal women has been reported to increase the risk of gallbladder disease requiring surgery.
Dementia
The Women’s Health Initiative Memory Study (WHIMS) was a substudy of the WHI trial and indicated an increased risk of dementia (loss of memory and intellectual function) in postmenopausal women age 65 and over taking oral combined estrogen plus progestin compared to women taking placebo.
The WHIMS indicated no difference in the risk of dementia in postmenopausal women age 65 and over with prior hysterectomy taking oral estrogen-alone compared to women taking placebo.

Proper use of this medication
Usual Dose
HOW TO USE Sandoz Estradiol Derm
Your doctor will explain when to start using Sandoz Estradiol Derm. The Sandoz Estradiol Derm patches are applied twice weekly on the same days of each week. Each patch should be worn continuously for 3 to 4 days. The dose of Sandoz Estradiol Derm will be based on the reason for its use, as determined by your physician. Your physician may adjust the dosage based on your response to treatment.
Estrogen is usually taken in a cyclic fashion (although your physician's instructions may be different depending upon your personal situation). This means that you would take estrogen on the first 21 or 25 days of the cycle, followed by 5 to 7 days without. Your next cycle starts with the next patch application.
Each box contains eight Sandoz Estradiol Derm patches. If your treatment is for less than 28 days of estrogen (cyclical therapy), you will have 1 or 2 patches leftover which can be used for the next month.
It is important that you take your medication as your physician has prescribed. Do not discontinue or change your therapy without consulting your physician first. You should talk regularly with your physician about how long you will need treatment with estrogen.
How and Where to Apply Sandoz Estradiol Derm
It is recommended that you change the site of application each time the patch is applied. However, each time you apply a patch you should always apply it to the same area of your body (i.e. if the patch is applied to the buttocks, move the patch from right side to left side, twice a week or more if there is any redness under the patch).
Preparing the Skin
In order for the patch to stick, the skin should be clean, dry and free of creams, lotions or oils. If you wish, you may use body lotion after the patch has been properly applied to the skin. The skin should not be irritated or broken, since this may alter the amount of hormone you get. Contact with water (bath, pool, or shower) won't affect the patch, although very hot water or steam may loosen it and therefore should be avoided (see Helpful Hints).
Where to Apply the Sandoz Estradiol Derm Patch
The buttock is the preferred place to apply the patch. Other suitable application sites are the sides, hip, lower back or lower abdomen. Change the site of application each time you put a patch on. You can use the same spot more than once but not twice in a row.
Avoid areas of the skin where clothing may rub the patch off or areas where the skin is very hairy or folded. Also avoid areas where the patch is likely to be exposed to the sun since this may affect how the patch works.
Do not apply Sandoz Estradiol Derm to your breast, since this may cause unwanted effects and discomfort.
Opening the Pouch
Each Sandoz Estradiol Derm patch is individually sealed in a protective pouch. Tear open this pouch at the indented notch and remove the patch. Do not use scissors, as you may accidentally cut and destroy the patch.
Removing the Liner
One side of the patch has the adhesive that attaches to your skin. The adhesive is covered by a protective liner that must be removed.
To separate the patch from the liner, hold the patch with the protective liner facing you. Peel off one side of the protective liner and discard it. Try to avoid touching the sticky side of the patch with your fingers.
Using the other half of the liner as a handle, apply the sticky side of the patch to a dry area of intact skin on the trunk of the body. Press the sticky side on the skin and smooth down.
Fold back the remaining side of the edge of the protective liner and pull it across the skin. Avoid touching the adhesive.
Don't worry if the patch buckles slightly because you can flatten it out after the liner has been removed. Apply the patch soon after opening the pouch and removing the liner.
Applying the Sandoz Estradiol Derm Patch
Apply the adhesive side to the spot you have chosen. Press it firmly in place with the palm of your hand for about 10 seconds, then run your finger around the edge, making sure there is good contact with the skin.
When and How to Remove the Patch
The Sandoz Estradiol Derm patch should be changed twice weekly. Always change it on the same 2 days of the week.
After you remove the patch fold it in half with the adhesive sides inwards. Throw it away, safely out of reach of children or pets.
Any adhesive left on your skin will rub off easily. Apply a new Sandoz Estradiol Derm patch on a different spot of clean, dry skin.
Helpful Hints
What to do if the Patch Falls Off
Should a patch fall off in a very hot bath or shower, shake the water off the patch. Dry your skin completely and reapply the patch (to a new area of skin) and continue your regular schedule. If it still does not stick, then apply a new patch and continue with your regular schedule.
If hot baths, saunas or whirlpools are something you enjoy and you find that the patch is falling off, you may consider removing the patch temporarily while you are in the water. If you do remove the patch temporarily, the adhesive side of the patch should be placed on the protective liner that was removed when originally applying the patch. Wax paper may be used as an alternate to the liner. This prevents the contents of the patch from emptying by evaporation while you are not wearing it.
In addition to exposure to very hot water, there are some other causes for the patch failing to stick. If you are having patches fall off regularly, this could be happening as a result of:
- using any type of bath oil
- using soaps with a high cream content
- using skin moisturizers before applying the patch
Patch adhesion may be improved if you avoid using these products, and by cleansing the site of application with rubbing alcohol before you apply the patch.
What to do if your Skin Becomes Red or Irritated Under or Around the Patch
As with any product that covers the skin for a period of time (such as bandages), the Sandoz Estradiol Derm patch can produce some skin irritation in some women. This varies according to the sensitivity of each woman.
Usually this redness does not pose any health concern to you but to reduce this problem, there are some things that you may do:
- choose the buttock as the site of application
- change the site of application of the Sandoz Estradiol Derm patch every time a new patch is applied, usually twice weekly.
Experience with the estradiol patch has shown that if you allow the patch to be exposed to the air for approximately 10 seconds after the protective liner has been removed, skin redness may not occur.
If redness and/or itching continues, you should consult your physician.
Always Remember
Your doctor has prescribed Sandoz Estradiol Derm for you after a careful review of your medical needs. Use it only as directed and do not give it to anyone else.
If you have any questions, contact your doctor or pharmacist.
Overdose Symptoms
Overdosage with estrogen may cause nausea, breast discomfort, fluid retention, bloating or vaginal bleeding in women.
If more medication has been taken than what has been prescribed, remove the patch and contact either your doctor, hospital, or emergency department immediately.
Missed Dose
If you forget to change a patch at the scheduled time, apply a new patch as soon as you remember. No matter what day that happens, go back to changing the patch on the same day as your initial schedule.
