Generic name: Estradiol topical lotionBrand names: Estrasorb
Why is Estrasorb prescribed?
Estrasorb is a topical lotion that contains the hormone estrogen. It's used to reduce the symptoms of moderate to severe hot flashes associated with menopause. The most common symptoms during a hot flash include sudden sweating, intense feelings of body heat, and sudden feelings of warmth spreading to the face, neck, and chest.
Most important fact about Estrasorb
Because estrogens have been linked with an increased risk of endometrial cancer (cancer in the lining of the uterus), it is essential to have regular checkups and to report any unusual vaginal bleeding to your doctor immediately.
How should you take Estrasorb?
Estrasorb lotion is packaged in foil pouches. Do not open the pouches until just before you're ready to use Estrasorb.
Apply Estrasorb in the morning. Be sure your skin is dry before applying the lotion, and do not rub it on skin that is red or irritated. Cut or tear open one pouch and apply the contents to your left thigh. Rub the lotion into your entire left thigh and calf for 3 minutes until Estrasorb is absorbed. You can rub any excess lotion remaining on your hands onto your buttocks. When you're done with the left leg, cut or tear open a second pouch and follow the same procedure on your right thigh and calf. Be sure to use all of the lotion in each pouch.
Wash your hands with soap and water when you're finished. Allow the application sites to dry completely before putting on clothes.
The legs are the only application sites recommended by the drug's manufacturer. It is not known if Estrasorb will be absorbed as well if it's applied to other parts of the body.
Do not apply Estrasorb and sunscreen at the same time, since sunscreen may affect how much of Estrasorb you absorb.
--If you miss a dose...
If you forget to apply Estrasorb in the morning, do it as soon as you remember. Do not apply Estrasorb more than once a day.
Store the pouches at room temperature.

Special warnings about Estrasorb
Estrogen therapy may increase the risk of heart disease, stroke, and blood clots. It could also increase the risk of certain cancers, including breast, uterine, and ovarian cancer. (Combination products that also contain progestin pose less risk of uterine cancer, but increase the risk of breast cancer.) If you are in danger of developing any of these, your doctor should take a complete medical and family history--and do a complete physical exam--before prescribing Estrasorb. As a general rule, you should have an examination at least once a year while using this product.
Estrogen therapy may also increase the risk of gallbladder disease and high calcium levels (hypercalcemia).
Serious eye problems, including blood clots in the retina, have been reported during estrogen therapy. Contact your doctor immediately if you suddenly lose all or part of your vision or you develop any eye problems. Also tell your doctor if you suddenly develop migraines, which could be related to eye problems.
Use Estrasorb with caution if you have a history of high blood pressure, endometriosis, liver problems, jaundice, or low calcium levels (hypocalcemia). Also be cautious if you have cholesterol problems, since using estrogen could trigger a spike in your triglyceride levels and possibly damage the pancreas.
While taking estrogen, get in touch with your doctor right away if you notice any of the following:Abdominal pain, tenderness, or swellingAbnormal bleeding from the vaginaBreast lumpsCoughing up bloodDifficulty with speechDizziness or faintingPain in your chest or calvesSevere headache or vomitingSudden shortness of breathVision changesWeakness or numbness of an arm or legYellowing of the skin or eyes
Because estrogen can affect the ability to handle blood sugar, diabetic women should use this product with caution. Be alert, too, for signs of fluid retention, which can be especially harmful for people with a heart condition or kidney problems. Estrogen can also worsen the symptoms of asthma, epilepsy, migraine, lupus, and the genetic disorder porphyria.
Estrogen could interfere with thyroid hormone metabolism. Tell your doctor if you have thyroid problems or are taking thyroid hormone, since you may need your dosage increased.
If you're having surgery or need long periods of bed rest, you should stop taking Estrasorb at least 4 to 6 weeks beforehand to avoid the risk of blood clots.
Possible food and drug interactions when using Estrasorb
If you take certain other drugs while using estrogen, the effects of either could be increased, decreased, or altered. It is especially important to check with your doctor before taking the following:Carbamazepine (Tegretol)Clarithromycin (Biaxin)Erythromycin (E-Mycin, Ery-Tab, Erythrocin)Grapefruit juiceItraconazole (Sporanox)Ketoconazole (Nizoral)PhenobarbitalRifampin (Rifadin)Ritonavir (Norvir)St. John's wort
