Cardiovascular Disorders, Probable Dementia, Breast Cancer, and Endometrial CancerEstrogen Plus Progestin TherapyCardiovascular Disorders and Probable DementiaEstrogens plus progestogen therapy should not be used for the prevention of cardiovascular disease or dementia.The Women's Health Initiative (WHI) estrogen plus progestin substudy reported an increased risk of deep vein thrombosis (DVT), pulmonary embolism (PE), stroke and myocardial infarction (MI) in postmenopausal women (50 to 79 years of age) during 5.6 years of treatment with daily oral conjugated estrogens (CE) [0.625 mg] combined with medroxyprogesterone acetate (MPA) [2.5 mg], relative to placebo.The WHI Memory Study (WHIMS) estrogen plus progestin ancillary study of WHI reported an increased risk of developing probable dementia in postmenopausal women 65 years of age or older during 4 years of treatment with daily CE (0.625 mg) combined with MPA (2.5 mg), relative to placebo. It is unknown whether this finding applies to younger postmenopausal women.Breast CancerThe WHI estrogen plus progestin substudy demonstrated an increased risk of invasive breast cancer.Only daily oral 0.625 mg CE and MPA were studied in the estrogen plus progestin substudy of the WHI. Therefore, the relevance of the WHI findings regarding adverse cardiovascular events, dementia and breast cancer to lower CE plus other MPA doses, other routes of administration, or other estrogen plus progestogen products is not known. Without such data, it is not possible to definitively exclude these risks or determine the extent of these risks for other products. Discuss with your patient the benefits and risks of estrogen plus progestogen therapy, taking into account her individual risk profile.Prescribe estrogens with or without progestogens at the lowest effective doses and for the shortest duration consistent with treatment goals and risks for the individual woman.Estrogen-Alone TherapyEndometrial CancerThere is an increased risk of endometrial cancer in a woman with a uterus who uses unopposed estrogens. Adding a progestogen to estrogen therapy has been shown to reduce the risk of endometrial hyperplasia, which may be a precursor to endometrial cancer. Perform adequate diagnostic measures, including directed or random endometrial sampling when indicated rule out malignancy in postmenopausal women with undiagnosed persistent or recurring abnormal genital bleeding.Cardiovascular Disorders and Probable DementiaThe WHI estrogen-alone substudy reported increased risks of stroke and DVT in postmenopausal women (50 to 79 years of age) during 7.1 years of treatment with daily oral CE (0.625 mg)-alone, relative to placebo.The WHIMS estrogen-alone ancillary study of WHI reported an increased risk of developing probable dementia in postmenopausal women 65 years of age or older during 5.2 years of treatment with daily CE (0.625 mg)-alone, relative to placebo. It is unknown whether this finding applies to younger postmenopausal women.Do not use estrogen-alone therapy for the prevention of cardiovascular disease or dementia.Only daily oral 0.625 mg CE was studied in the estrogen-alone substudy of the WHI. Therefore, the relevance of the WHI findings regarding adverse cardiovascular events and dementia to lower CE doses, other routes of administration, or other estrogen-alone products is not known. Without such data, it is not possible to definitively exclude these risks or determine the extent of these risks for other products.

Proper use of estradiol and levonorgestrel
It is very important that you use estradiol and levonorgestrel 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 and levonorgestrel 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 and levonorgestrel comes with a patient information insert. Read and follow the instructions carefully. Ask your doctor if you have any questions.
- Wash your hands with soap and water before and after you use estradiol and levonorgestrel.
- Carefully tear open the pouch when you are ready to put the patch on your skin. Do not cut it. Do not touch the sticky side of the patch.
- 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 (eg, 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 or stomach. 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 and levonorgestrel. 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.
The dose of estradiol and levonorgestrel 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 and levonorgestrel. 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.
- For transdermal dosage form (patch):
- For hot flashes and other symptoms caused by menopause, and prevention of osteoporosis after menopause:
- Adults—At first, apply one patch (0.045 milligrams (mg) of estradiol and 0.015 mg of levonorgestrel) to the lower stomach or upper buttocks area once a week. Your doctor may adjust your dose as needed.
- Children—Use is not recommended.
- For hot flashes and other symptoms caused by menopause, and prevention of osteoporosis after menopause:
If you forget to wear or change a patch, put one on as soon as you can. If it is almost time to put on your next patch, wait until then to apply a new patch and skip the one you missed. Do not apply extra patches to make up for a missed dose.
Store the patches at room temperature in a closed container, away from heat, moisture, and direct light.
Keep out of the reach of children.
Do not keep outdated medicine or medicine no longer needed.
Ask your healthcare professional how you should dispose of any medicine you do not use.
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.
Precautions while using estradiol and levonorgestrel
It is very important that your doctor check your progress at regular visits to make sure estradiol and levonorgestrel is working properly and does not cause unwanted effects. These visits may be every 3 to 6 months. Pelvic exam, breast exam, and mammogram (breast x-ray) may be needed to check for unwanted effects, unless your doctor tells you otherwise. Be sure to keep all appointments.
It is unlikely that a postmenopausal woman may become pregnant. But, you should know that using estradiol and levonorgestrel 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 and levonorgestrel 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 and levonorgestrel 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 and levonorgestrel may increase your risk of dementia, especially in women 65 years of age and older.
Using estradiol and levonorgestrel may increase your risk for gallbladder disease. Talk with your doctor right away if you have stomach pain, nausea, or vomiting.
Tell the medical doctor or dentist in charge that you are using estradiol and levonorgestrel before any kind of surgery (including dental surgery) or emergency treatment. Your doctor will decide whether you should continue using estradiol and levonorgestrel. Estradiol and levonorgestrel 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 and levonorgestrel. Your doctor may want you to have your eyes checked by an ophthalmologist (eye doctor).
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.
