estradiol (Transdermal route)Pronunciation
Estrogens increase the risk of endometrial cancer; monitor for abnormal vaginal bleeding. Estrogens with or without progestins should not be used for the prevention of cardiovascular disease or dementia. Increased risks of myocardial infarction, stroke, invasive breast cancer, pulmonary emboli, and deep vein thrombosis in postmenopausal women (50 to 79 years of age) have been reported. An increased risk of developing probable dementia in postmenopausal women 65 years of age or older has also been reported. Risks should be assumed to be similar for other doses, combinations, and dosage forms of estrogens and progestins. Estrogens, with or without progestins, should be prescribed at the lowest effective doses and for the shortest duration possible .Transdermal route(Patch, Extended Release)

Estrogens, with or without progestins, should be prescribed at the lowest effective doses and for the shortest duration consistent with treatment goals and risks for the individual woman .Transdermal route(Patch, Extended Release)
There is an increased risk of endometrial cancer in a woman with a uterus who uses unopposed estrogens. Estrogen-alone therapy should not be used for the prevention of cardiovascular disease or dementia. The Women's Health Initiative (WHI) estrogen-alone substudy reported increased risks of stroke and deep vein thrombosis (DVT). The WHI Memory Study (WHIMS) estrogen-alone ancillary study of WHI reported an increased risk of probable dementia in postmenopausal women 65 years of age and older. Estrogen plus progestin therapy should not be used for the prevention of cardiovascular disease or dementia. The WHI estrogen plus progestin substudy reported increased risks of stroke, DVT, pulmonary embolism (PE), and myocardia infarction (MI). The WHI estrogen plus progestin substudy reported increased risks of invasive breast cancer. The WHIMS estrogen plus progestin ancillary study of WHI reported an increased risk of probable dementia in postmenopausal women 65 years of age and older .Transdermal route(Gel/Jelly)
Unopposed estrogens increase the risk of endometrial cancer in women with a uterus. Estrogen alone or with a progestin should not be used for the prevention of cardiovascular disease or dementia. Increased risks of stroke and DVT have been reported with estrogen-alone therapy and increased risks of stroke, DVT, pulmonary embolism, myocardial infarction, and invasive breast cancer have been reported with estrogen plus progestin therapy. An increased risk of probable dementia in postmenopausal women aged 65 and older has been reported with estrogen alone and estrogen plus progestin therapy. Risks should be assumed to be similar for other doses, combinations, and dosage forms of estrogens and progestins. Estrogens, with or without progestins, should be prescribed at the lowest effective doses and for the shortest duration possible .Transdermal route(Spray)
Unopposed estrogens increase the risk of endometrial cancer. Adding a progestin will reduce the risk of endometrial hyperplasia, which may be a precursor to endometrial cancer. Diagnostic measures should be undertaken to rule out malignancy in postmenopausal women with undiagnosed persistent or recurring abnormal genital bleeding. Estrogens with or without progestins should not be used for the prevention of cardiovascular disease or dementia. Increased risks of stroke and deep vein thrombosis in postmenopausal women (50 to 79 years of age) using estrogen alone have been reported. Increased risks of myocardial infarction, stroke, invasive breast cancer, pulmonary emboli, and deep vein thrombosis in postmenopausal women (50 to 79 years of age) using estrogens combined with progestins have been reported. An increased risk of developing probable dementia in postmenopausal women 65 years of age or older has also been reported in women receiving estrogen alone or estrogen combined with progestins. Risks should be assumed to be similar for other doses, combinations, and dosage forms of estrogens and progestins. Estrogens, with or without progestins, should be prescribed at the lowest effective doses and for the shortest duration possible. Breast budding and breast masses in prepubertal females and gynecomastia and breast masses in prepubertal males have been reported following unintentional secondary exposure. Patients should strictly adhere to recommended instructions for use .

Uses For estradiol
Estradiol transdermal gel, patch, and spray are used to treat moderate to severe hot flashes and other symptoms of menopause or low amounts of estrogen. It is also used to treat changes in and around the vagina (such as vaginal dryness, itching, and burning) caused by low estrogen levels or menopause. estradiol is also used to treat certain conditions in women before menopause if their ovaries do not make enough estrogens naturally, and prevent osteoporosis after menopause.
Estradiol is an estrogen hormone. The hormone from the patch, gel, and spray is absorbed through your skin into your body. It works by preventing symptoms, such as feelings of warmth in the face, neck, and chest, or sudden strong feelings of heat and sweating (hot flashes) in women during menopause.
estradiol is available only with your doctor's prescription.
Before Using estradiol
In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For estradiol, the following should be considered:
Tell your doctor if you have ever had any unusual or allergic reaction to estradiol or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.
Use of estradiol transdermal patch, gel, and spray is not indicated in the pediatric population. Safety and efficacy have not been established.
Although appropriate studies on the relationship of age to the effects of estradiol transdermal patch, gel, and spray have not been performed in the geriatric population, no geriatric-specific problems have been documented to date. However, elderly patients are more likely to have breast cancer, stroke, or dementia, which may require caution in patients receiving estradiol transdermal patch, gel and spray.

Proper Use of estradiol
It is very important that you use estradiol only as directed by your doctor. Do not use more of it, do not use it more often, and do not use it for a longer time than your doctor ordered. To do so may cause unwanted side effects.
estradiol is for use on the skin only. Do not get it in your eyes, nose, mouth, breast, or vagina. Do not use it on skin areas that have cuts, scrapes, or burns. If it does get on these areas, rinse it off right away with water.
estradiol comes with a patient information insert. Read and follow the instructions in the insert carefully. Ask your doctor if you have any questions.
Wash your hands with soap and water before and after using estradiol.
To use the patch:
- Wash your hands with soap and water before and after you use estradiol.
- Carefully tear open the pouch when you are ready to put the patch on your skin. Do not cut it.
- Peel off the backing from the patch and apply the patch to a clean, dry, and hair-free area of the lower stomach or upper buttock area. This area must be free of powder, oil, or lotion for the patch to stick on to your skin.
- Press the patch firmly in place with your hand for about 10 seconds.
- Do not apply the patch on the breast or over any skin folds. Do not apply the patch on oily, broken, burned, or irritated skin, or areas with skin conditions (such as birth marks, tattoos). Avoid applying the patch on the waistline or other places where tight clothing may rub it off.
- Wear the patch at all times until it is time to put on a new patch. Do not expose it to the sun for long periods of time.
- When replacing your patch, make sure to apply the new patch to a different area of your lower abdomen. Wait at least 1 week before applying a patch to the same area.
- When changing a patch, slowly peel it off from your skin. If you have any patch adhesive left on your skin, allow it to dry for 15 minutes and gently rub the sticky area with oil or lotion to remove it. It is best to change your patch on the same days of each week to help you remember.
- You may take a bath, shower, or swim while using estradiol. Doing so will not affect the patch.
- If a patch falls off, just put it back on a different area. If the patch does not stick completely, put on a new patch but continue to follow your original schedule for changing your patch.
- To throw away a used patch: Fold the patch in half with the sticky side together and place it in a sturdy child-proof container. Throw this container in the trash away from children and pets. Do not flush the patch down the toilet.
To use the spray:
- The spray form of estradiol comes in an applicator that delivers a measured amount of estradiol to the skin with each spray. When using a new spray applicator, prime the pump by holding the spray upright and pumping 3 times. Priming is only necessary the first time you use a new spray applicator; do not prime again.
- Apply the medicine to clean, dry, and unbroken skin on the inside of the forearm between the elbow and the wrist. Do not apply the medicine directly to your breasts or in or around the vagina.
- Allow the medicine to dry for at least 2 minutes before dressing, and at least 1 hour before washing.
- If your doctor tells you to increase your dose, move the applicator to an area of the skin next to your previous application site, before applying the second or third spray.
- Do not rub Evamist® spray into your skin.
- Do not allow your child to touch the area of the arm where the medicine was sprayed. If you cannot avoid being close with your child, wear clothes with long sleeves to cover the application site.
- If your child comes in direct contact with the arm where the medicine was sprayed, wash your child's skin right away with soap and water.
- Do not allow your pets to lick or touch the arm where the medicine was sprayed.
- Always place the protective cover back on the applicator of the spray.
- Do not use the applicator for more than 75 sprays.
- Apply sunscreen at least 1 hour before applying Evamist®.
To use the gel:
- The gel form of estradiol comes in a pump. Each time you press the pump you will get the same amount of medication. You may need to prime the pump by pumping 3 times (EstroGel®) or 10 times (Elestrin™) the first time you use it. Follow the patient instructions for the container you use. After you prime the pump, do not press the pump more than 1 time each time you use it.
- Apply the gel to clean, dry, and unbroken skin. Spread the gel as thinly as possible over the entire area on the inside and outside of your upper arm and shoulder area. Do not apply the medicine directly to your breasts or in or around your vagina.
- Do not allow others to come in contact with the area of skin where you applied the gel for at least 1 hour after you use the medicine. Do not allow others to apply the gel for you. Allow the medicine to dry for at least 5 minutes before you dress.
- Apply sunscreen at least 25 minutes after using the gel. Avoid applying sunscreen on the same application site for 7 days or more.
The gel and spray contain alcohol and are flammable. Avoid using it near an open flame or while smoking.
The dose of estradiol will be different for different patients. Follow your doctor's orders or the directions on the label. The following information includes only the average doses of estradiol. If your dose is different, do not change it unless your doctor tells you to do so.
The amount of medicine that you take depends on the strength of the medicine. Also, the number of doses you take each day, the time allowed between doses, and the length of time you take the medicine depend on the medical problem for which you are using the medicine.

Precautions While Using estradiol
It is very important that your doctor check your progress at regular visits to make sure estradiol is working properly and does not cause unwanted effects. Pelvic exam, breast exam, and mammogram (breast x-ray) may be needed to check for unwanted effects, unless your doctor tells you otherwise.
It is unlikely that a postmenopausal woman may become pregnant. But, you should know that using estradiol while you are pregnant could harm your unborn baby. If you think you have become pregnant while using the medicine, tell your doctor right away.
Using estradiol may increase your risk for having blood clots, strokes, or heart attacks. This risk may continue even after you stop using the medicine. Your risk for these serious problems is even greater if you have high blood pressure, high cholesterol in your blood, diabetes, or if you are overweight or smoke cigarettes. Contact your doctor immediately if you experience confusion, difficulty speaking, double vision, headaches, an inability to move arms, legs or facial muscle, or an inability to speak.
Using estradiol over a long period of time may increase your risk of breast cancer, endometrial cancer, or uterine cancer. Talk with your doctor about this risk. If you still have your uterus (womb), ask your doctor if you should also use a progestin medicine. Check with your doctor if you have unusual vaginal bleeding.
Using estradiol may increase your risk of dementia, especially in women 65 years of age and older.
Tell the medical doctor or dentist in charge that you are using estradiol before any kind of surgery (including dental surgery) or emergency treatment. Your doctor will decide whether you should continue using estradiol. estradiol may also affect the results of certain medical tests.
Check with your doctor immediately if severe headache or sudden loss of vision or any other change in vision occurs while you are using estradiol. Your doctor may want you to have your eyes checked by an ophthalmologist (eye doctor).
Check with your child's doctor right away if your child starts to have the following symptoms: nipple or breast swelling or tenderness in females, or enlargement of the breasts in males. Your child may have been exposed to estradiol.
Do not allow your pets to lick or touch the arm where estradiol was applied. Small pets may be sensitive to estradiol. Call your pet's veterinarian if your pet starts to have the following symptoms: nipple or breast enlargement, swelling of the vulva, or any signs of illness.
Do not take other medicines or drink grapefruit juice unless you discuss it with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal (eg, St. John's wort) or vitamin supplements.
