Faslodex: Uses, Dosage, Demographic, Side Effects, Interactions, and Generic Options Medically Cited Faslodex, also known as fulvestrant, is a medication used to treat breast cancer that has spread to other parts of the body. It works by blocking the effects of estrogen, a hormone that can promote the growth of breast cancer cells. Faslodex is given as an injection into the muscle. Uses: Faslodex is used to treat hormone receptor-positive, metastatic breast cancer in postmenopausal women whose cancer has progressed after treatment with other anti-estrogen medications. It is also sometimes used as first-line treatment for postmenopausal women with advanced breast cancer that has spread to other parts of the body. Dosage: The recommended dose of Faslodex is 500 mg given as two 250 mg injections, one in each buttock, on days 1, 15, and 29, then once a month thereafter. The injections should be given slowly over one to two minutes. Demographic: Faslodex is only recommended for postmenopausal women. It is not recommended for use in premenopausal women or men. Side Effects: Common side effects of Faslodex include hot flashes, nausea, vomiting, loss of appetite, constipation, diarrhea, weakness, headache, back pain, joint pain, muscle pain, cough, difficulty breathing, and fever. These side effects are usually mild to moderate in severity and go away on their own within a few days to weeks. Serious side effects of Faslodex are rare but can include allergic reactions, such as hives, swelling of the face, lips, tongue, or throat, and difficulty breathing. Seek medical attention immediately if you experience any of these symptoms after receiving a Faslodex injection. Interactions: Faslodex may interact with other medications you are taking. Tell your doctor about all medications you are taking, including over-the-counter drugs, vitamins, and herbal supplements. You should not take Faslodex if you are taking any medications that contain estrogen, including birth control pills, hormone replacement therapy, or tamoxifen. Generic Options: Faslodex is a brand-name medication, and there are no generic versions available at this time. However, your doctor may be able to prescribe another medication that works in a similar way if Faslodex is not affordable or covered by your insurance.
