What is Estrasorb?
Estrasorb is topical emulsion containing estradiol. Estradiol is a form of estrogen, a female sex hormone that regulates many processes in the body.
Estrasorb is used to after menopause to reduce moderate to severe hot flashes. The ovaries normally stop making estrogens when a woman is between 45 to 55 years old. When the estrogen levels begin dropping, some women develop very uncomfortable symptoms, such as feelings of warmth in the face, neck, and chest, or sudden strong feelings of heat and sweating (“hot flashes” or “hot flushes”). In some women, the symptoms are mild, and they will not need estrogens. In other women, symptoms can be more severe.
Estrasorb may also be used for purposes not listed in this medication guide.
You should not use Estrasorb if you have any of the following conditions: a history of heart attack, stroke, or blood clot, a bleeding or blood-clotting disorder, liver disease, abnormal vaginal bleeding, history of an allergic reaction to estradiol topical, or a hormone-related cancer such as breast or uterine cancer.
Do not use Estrasorb if you are pregnant.
Estradiol may increase your risk of developing a condition that may lead to uterine cancer. Call your doctor at once if you have any unusual vaginal bleeding while using Estrasorb.
Children should avoid coming into contact with skin areas where you have applied Estrasorb. Topical estradiol is absorbed through the skin and can cause side effects in a child who comes into contact with Estrasorb or with skin where the medicine was applied.
Estradiol should not be used to prevent heart disease, stroke, or dementia, because this medicine may actually increase your risk of developing these conditions. Long-term use may also increase your risk of breast cancer or blood clot.
Before this medicine
You should not use Estrasorb if you have:
abnormal vaginal bleeding that has not been checked by a doctor;
any type of breast, uterine, or hormone-dependent cancer;
a history of heart attack, stroke, or blood clot (especially in your lung or your lower body);
a bleeding or blood-clotting disorder;
if you are pregnant or may become pregnant; or
if you have ever had an allergic reaction to estradiol topical.
Estradiol will not prevent heart disease, heart attack, stroke, breast cancer, or dementia, and may actually increase your risk of developing these conditions. Estradiol may also increase your risk of uterine or ovarian cancer. Talk with your doctor about your individual risks.
To make sure Estrasorb is safe for you, tell your doctor if you have:
unusual vaginal bleeding;
epilepsy or other seizure disorder;
liver or kidney disease;
a thyroid disorder;
high levels of calcium in your blood (hypercalcemia);
gallbladder disease; or
risk factors for coronary artery disease (such as diabetes, smoking, being overweight, having high blood pressure or high cholesterol, having a family history of coronary artery disease, being older than 40, or if you have had a hysterectomy).
Do not use Estrasorb if you are pregnant. Use effective birth control to prevent pregnancy while you are using Estrasorb.
Estradiol can pass into breast milk and may harm a nursing baby. This medicine may also slow breast milk production. Do not use Estrasorb if you are breast-feeding a baby.
How should I use Estrasorb?
Use Estrasorb exactly as prescribed by your doctor. Follow all directions on your prescription label. Do not use this medicine in larger or smaller amounts or for longer than recommended.
Estradiol may increase your risk of developing a condition that may lead to uterine cancer. Your doctor may prescribe a progestin to take while you are using estradiol, to help lower this risk. Report any unusual vaginal bleeding right away.
Read all patient information, medication guides, and instruction sheets provided to you. Ask your doctor or pharmacist if you have any questions.
Apply Estrasorb only to clean, dry, unbroken skin. Do not apply to skin that is red or irritated. Never apply this medicine to the breasts.
To use Estrasorb topical emulsion:
Apply Estrasorb while you are sitting comfortably. You will use two foil pouches each time you apply this medication, unless your doctor has told you otherwise.
Cut or tear open the foil pouch and place the pouch on top of your left thigh, with the open end of the pouch pointing toward your knee.
Hold the pouch with one hand and use the fingers of your other hand to gently push all of Estrasorb emulsion out of the pouch and onto your thigh.
Spend at least 3 minutes rubbing the Estrasorb emulsion into your entire left thigh and calf. Rub any excess medicine onto your buttocks.
Cut or tear open the second pouch and apply the Estrasorb emulsion to your right leg using the same method described above.
Wash your hands with soap and water after applying the emulsion. Avoid allowing other people to get this medicine on their skin. If this happens, wash the area thoroughly with soap and water.
Children should avoid coming into contact with skin areas where you have applied Estrasorb. Topical estradiol is absorbed through the skin and can cause premature puberty in a child who comes into contact with this medicine or with skin where the medicine was applied. Cover treated areas with clothing to protect others from coming into contact with the skin where you apply this medicine.
Your doctor should check your progress on a regular basis (every 3 to 6 months) to determine whether you should continue this treatment. Self-examine your breasts for lumps on a monthly basis, and have regular mammograms while using estradiol.
If you need surgery or medical tests or if you will be on bed rest, you may need to stop using Estrasorb for a short time. Any doctor or surgeon who treats you should know that you are using estradiol.
Store Estrasorb at room temperature away from moisture and heat.
What happens if I miss a dose?
Use the missed dose as soon as you remember. If you are more than 12 hours late, skip the missed dose. Do not use extra Estrasorb emulsion to make up the missed dose.
What happens if I overdose?
Seek emergency medical attention or call the Poison Help line at 1-800-222-1222. Overdose symptoms may include nausea, vomiting, stomach pain, breast tenderness, drowsiness, and vaginal bleeding.
What should I avoid while using Estrasorb?
Do not apply sunscreen to your skin at the same time you apply Estrasorb.
Avoid getting Estrasorb emulsion in your eyes. If this does happen, rinse with water.
Grapefruit and grapefruit juice may interact with estradiol and lead to potentially dangerous effects. Discuss the use of grapefruit products with your doctor.
