It is an antineoplastic (anticancer) drug that belongs to a class called estrogen receptor antagonists. It is an injectable solution that is used to treat locally advanced or metastatic breast cancer in postmenopausal, <a href=\"https:\/\/www.cancer.gov\/publications\/dictionaries\/cancer-terms\/def\/estrogen-receptor-positive\">estrogen receptor-positive women<\/a>. Fulvestrant is a form of endocrine (hormonal) therapy known as a selective estrogen receptor degrader (SERD).

Instead of directly killing rapidly dividing cells like cytotoxic chemotherapy, endocrine therapies work by blocking hormone signaling or lowering hormone effects in the body. Fulvestrant works by binding to the estrogen receptor and promoting its degradation, which helps slow or stop the growth of estrogen receptor\u2013positive breast cancer.<\/span><\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"What_Is_Endocrine_Hormonal_Therapy-2\"><\/span><b><strong>What Is Endocrine (Hormonal) Therapy?<\/strong><\/b><span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p><span style=\"font-weight: 400;\"><span style=\"font-weight: 400;\">Endocrine therapy is a cancer treatment used for tumors that depend on hormones such as estrogen to grow.

It is recommended to wear gloves when handling or administering this medication and to keep it stored in its original container.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"How_Is_Fulvestrant_Used\"><\/span>How Is Fulvestrant Used?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p><span style=\"font-weight: 400;\">Fulvestrant has been approved by the Food and Drug Administration (FDA) to treat certain types of breast cancer. It may be used alone or in combination with other anticancer therapies, such as CDK4\/6 inhibitors (for example, palbociclib [Ibrance], abemaciclib [Verzenio], or ribociclib [Kisqali]), depending on the cancer\u2019s characteristics and prior treatment history. When used in appropriate patients, combination therapy can improve outcomes such as delaying cancer progression.<\/span><\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Available_Formulations\"><\/span><b>Available Formulations<\/b><span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p><span style=\"font-weight: 400;\">Fulvestrant is only available in the form of an injection to be administered intramuscularly in the buttocks (gluteal) area. Each pre-filled syringe is available as a 5 ml dose, which contains 250 mg of fulvestrant. Therefore, each ml contains 50 mg of fulvestrant. Other ingredients included in the injection are ethanol (96%), <a href=\"https:\/\/go.drugbank.com\/drugs\/DB06770\">benzyl alcohol<\/a> (100 mg\/ml), benzyl benzoate, and refined castor oil.<\/span><\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Directions_for_Use\"><\/span><b>Directions for Use<\/b><span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p><span style=\"font-weight: 400;\">Fulvestrant may be taken without regard to food. The pre-filled syringe of fulvestrant is supposed to be used for intramuscular injection into the buttocks (gluteal) area only. It should never be administered intravenously, subcutaneously, or intra-arterially. Two pre-filled syringes (250 mg per 5 ml) should be administered, one in each buttock, slowly over 1 to 2 minutes per injection. Do not administer more than 5 ml per buttock.<\/span><\/p>\n\n\n\n<p><span style=\"font-weight: 400;\">To prepare each syringe for administration, hold the syringe upright, carefully tilt the syringe cap back and forth (without twisting) until the cap disconnects for removal. Pull the cap off by pulling up without touching the syringe tip (to maintain sterility), attach the safety needle to the syringe tip, and twist firmly to lock. Remove the needle cap by pulling straight off to avoid damaging the needle point, remove the needle sheath, and expel excess air from the syringe before administration. Refer to the product labeling for more detailed instructions.<\/span><\/p>\n\n\n\n<p><span style=\"font-weight: 400;\">Fulvestrant is initially given as 500 mg on days 1, 15, and 29, and then dosed 500 mg once every 4 weeks for maintenance. The dose is dependent on the cancer type and severity. Verify the correct dose and frequency with your provider. The dose should not be more or less than what is prescribed.<\/span><\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Missed_Dose\"><\/span><b>Missed Dose<\/b><span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p><span style=\"font-weight: 400;\">If you have missed a dose of this medication, contact your physician immediately, as this drug should be taken on a regular schedule. Do not attempt to catch up by doubling the dose.<\/span><\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Storage\"><\/span><b>Storage<\/b><span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p><span style=\"font-weight: 400;\">Keep medication stored in the original carton. Do not freeze and keep protected from light. Storage requirements may vary by product. Refer to the manufacturer\u2019s labeling for further details. Fulvestrant should be stored in the refrigerator; however, some variations of fulvestrant can be stored at either room temperature or in the refrigerator. To minimize discomfort, you can take the medication out of the refrigerator up to 1 hour before the scheduled dose and allow it to reach room temperature. Do not reuse any single-use syringes and discard any unused portion. Dispose of the product as directed; do not flush down the drain.<\/span><\/p>\n\n\n\n<div  id=\"call-to-action-aa093c527a92878dd980baf30b0f0942\" style=\"\" class=\"ct_call_to_action\">\n\t<div class=\"container\">\n\t\t<div class=\"block-wrap cta\">\n\t\t\t<div class=\"block-column\">\n\t\t\t\t<div class=\"cta_headings\">\n\t\t\t\t\t\t\t\t\t\t\t<h4 class=\"cta__heading\">\n\t\t\t\t\t\t\tSpeak to a Specialist About Copay Assistance\t\t\t\t\t\t<\/h4>\n\t\t\t\t\t\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t\t\t\t\t<span class=\"cta_btn\">\n\t\t\t\t\t\t<a href=\"#form\">Consult a Chemo Specialist<\/a>\n\t\t\t\t\t\t\t\t\t\t\t<\/span>\n\t\t\t\t\t\t\t<\/div>\n\n\t\t<\/div>\n\t<\/div>\n<\/div>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"What_To_Avoid_While_Taking_Fulvestrant\"><\/span>What To Avoid While Taking Fulvestrant<img loading=\"lazy\" decoding=\"async\" width=\"420\" height=\"280\" class=\"wp-image-18370 size-full alignright\" src=\"https:\/\/ameripharmaspecialty.com\/wp-content\/uploads\/2022\/01\/fulvestrant-2.jpg\" alt=\"doctor with patient\" srcset=\"https:\/\/ameripharmaspecialty.com\/wp-content\/uploads\/2022\/01\/fulvestrant-2.jpg 420w, https:\/\/ameripharmaspecialty.com\/wp-content\/uploads\/2022\/01\/fulvestrant-2-300x200.jpg 300w, https:\/\/ameripharmaspecialty.com\/wp-content\/uploads\/2022\/01\/fulvestrant-2-330x220.jpg 330w, https:\/\/ameripharmaspecialty.com\/wp-content\/uploads\/2022\/01\/fulvestrant-2-86x57.jpg 86w, https:\/\/ameripharmaspecialty.com\/wp-content\/uploads\/2022\/01\/fulvestrant-2-167x111.jpg 167w, https:\/\/ameripharmaspecialty.com\/wp-content\/uploads\/2022\/01\/fulvestrant-2-280x187.jpg 280w, https:\/\/ameripharmaspecialty.com\/wp-content\/uploads\/2022\/01\/fulvestrant-2-370x247.jpg 370w\" sizes=\"auto, (max-width: 420px) 100vw, 420px\" \/><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p><\/p>\n\n\n\n<p><span style=\"font-weight: 400;\">While receiving fulvestrant, you must follow some precautions. Always tell your physician about any medication you are already taking. Do not start or stop any prescription, over-the-counter (OTC), vitamin, or herbal product without prior consent from your physician or pharmacist, as they may have some significant interactions with fulvestrant.<\/span><\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Pregnancy_and_Fulvestrant\"><\/span>Pregnancy and Fulvestrant<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p><span style=\"font-weight: 400;\">Pregnancy status must be checked within 7 days prior to starting treatment in women of childbearing age. Effective contraception must be used during treatment and for 1 year after the last dose. Fulvestrant may cause fetal harm and is therefore not recommended for women who are breastfeeding during therapy. Breastfeeding should also be avoided for at least 1 year after the last dose.<\/span><\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Side_Effects\"><\/span>Side Effects<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p><span style=\"font-weight: 400;\">As with any other medication, you may encounter side effects while taking fulvestrant. A few things to remember are:<\/span><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>You may not have all the side effects listed below. Many people may experience little to no side effects.<\/li>\n\n\n\n<li>The severity of side effects may vary from person to person, so don\u2019t compare your side effects with other people\u2019s experiences.<\/li>\n\n\n\n<li>Most of the side effects will improve when therapy is discontinued.<\/li>\n\n\n\n<li>These side effects are easily manageable most of the time either by readjusting the dose of fulvestrant or using additional medications to treat the symptoms. Consult with your physician or pharmacist to explore available options.<\/li>\n\n\n\n<li>Do not hide any symptoms; when you feel any discomfort, do not hesitate to tell your physician or pharmacist about it.<\/li>\n<\/ul>\n\n\n\n<p><b>Note<\/b><span style=\"font-weight: 400;\">: This is not a comprehensive list of all side effects.

The area where the medication is injected may feel sore for a few hours or days after injection. This may also be accompanied by mild bruising, swelling, or redness at the injection site. These pains can be controlled using over-the-counter painkillers like Tylenol or Motrin, but usually, they will resolve on their own within a few days.
