Chemotherapy?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p>While both are used to treat cancer, they work in different ways:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><a href=\"https:\/\/ameripharmaspecialty.com\/oral-chemotherapy-cancer-drugs\/\"><strong>Chemotherapy<\/strong><\/a> uses cytotoxic (cell-killing) drugs to attack all rapidly dividing cells in the body. Because it affects healthy cells as well as cancer cells, it often causes side effects like hair loss.<\/li>\n\n\n\n<li><strong>Herceptin (Targeted Therapy)<\/strong> is a monoclonal antibody. It acts like a &#8220;guided missile&#8221; that specifically seeks out and attaches to the HER2 protein on the surface of cancer cells. This blocks the signals that tell the cancer to grow, often sparing more healthy cells than traditional chemotherapy.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"How_Is_Herceptin_Used\"><\/span>How Is Herceptin Used?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p><span style=\"font-weight: 400;\">Herceptin has been approved by the Food and Drug Administration (FDA) to treat HER2-positive breast cancer and HER2-positive gastric or gastroesophageal junction cancers. It can be prescribed alone or with other <a href=\"https:\/\/ameripharmaspecialty.com\/oral-chemotherapy-cancer-drugs\/\">anti-cancer medications<\/a>.<\/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;\">Herceptin is available as a solution for intravenous injection only. Brand-name Herceptin is supplied as a 150 mg single-dose vial, though other biosimilar formulations are available in different-sized vials. The total duration of therapy typically should not exceed 1 year (52 weeks), but this may vary depending on the patient\u2019s condition and cancer severity.<\/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;\">Herceptin is typically dosed to be given once every 1 to 3 weeks, depending on cancer type and severity. The dose and schedule are determined by the prescribing provider and should be followed exactly. The dose is determined using the patient\u2019s body weight. The initial dose (also known as the loading dose) is typically infused over 90 minutes if tolerated, and subsequent infusions (maintenance doses) can be infused over 30 \u2013 90 minutes.<\/span><\/p>\n\n\n\n<p><span style=\"font-weight: 400;\">Do not administer Herceptin with <a href=\"https:\/\/www.drugs.com\/dextrose-5-in-water.html\">dextrose in water (D5W)<\/a> or with any other medications. It should be mixed with bacteriostatic or sterile water for injection only and diluted with normal saline. Herceptin should NOT be administered as an IV push or rapid bolus. Trastuzumab is available alone or in combination with other drugs. Different trastuzumab products are NOT interchangeable; only administer exact medication 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;\">This medicine needs to be administered on a fixed schedule. If you miss a dose, contact your physician for further instructions immediately.&nbsp;<\/span><\/p>\n\n\n\n<p>If a scheduled dose is delayed by <strong>one week or less<\/strong>, the usual maintenance dose should be administered as soon as possible. Subsequent maintenance doses should be administered 1 to 3 weeks later (based on the patient\u2019s normal maintenance dose schedule).<\/p>\n\n\n\n<p><span style=\"font-weight: 400;\">If a dose is missed by <\/span><b>over one week<\/b><span style=\"font-weight: 400;\">, a re-loading dose should be administered over 90 minutes as soon as possible. The usual maintenance dose is then administered 1 to 3 weeks later (based on the patient&#8217;s normal maintenance dose schedule).<\/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;\">As there are lots of different variations of trastuzumab, storage times vary by product; refer to the individual product labeling for details. Prior to reconstitution, vials should be stored in the refrigerator. Some products should be stored in intact vials in the original carton to protect from light. Some solutions are preservative-free, and therefore, they should be used immediately. Others can be refrigerated for up to 24 hours (depending on the product or vial size). Do not freeze or shake Herceptin vials. Always refer to the specific product labeling for storage and stability information, as requirements may differ between brand-name Herceptin and other trastuzumab biosimilar products.<\/span><\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"What_To_Avoid_While_Taking_Herceptin\"><\/span>What To Avoid While Taking Herceptin<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p><span style=\"font-weight: 400;\">While taking Herceptin therapy, you must follow some precautions. Always tell your physician about any medications you are already taking. <\/span><b>Do not take any drug or medicine (even herbals, vitamins, or over-the-counter medications) without prior consent from your physician or pharmacist<\/b><span style=\"font-weight: 400;\">. They may have some significant interactions with Herceptin.<\/span><\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Pregnancy_and_Herceptin\"><\/span>Pregnancy and Herceptin<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p><span style=\"font-weight: 400;\">Exposure to Herceptin during pregnancy may result in a decrease in amniotic fluid, which can severely impact the fetus and lead to delayed growth and malformations. Pregnancy status must be checked prior to starting Herceptin therapy in women of childbearing age, and effective contraception must be used during treatment and for 7 months after the last dose. Herceptin may cause fetal harm and is therefore not recommended for women who are breastfeeding during therapy. Breastfeeding should also be avoided for at least 7 months after the last dose.&nbsp;<\/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 Herceptin. A few things to remember are:<\/span><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><span style=\"font-weight: 400;\">You may not have all the side effects listed below. Many people may experience little to no side effects.<\/span><\/li>\n\n\n\n<li><span style=\"font-weight: 400;\">The severity of side effects may vary from person to person, so don\u2019t compare your side effects with other people\u2019s experiences.<\/span><\/li>\n\n\n\n<li><span style=\"font-weight: 400;\">Most of the side effects will improve when therapy is discontinued.<\/span><\/li>\n\n\n\n<li><span style=\"font-weight: 400;\">Many side effects are manageable with supportive care or dose adjustments. Consult with your physician or pharmacist to explore available options.<\/span><\/li>\n\n\n\n<li><span style=\"font-weight: 400;\">Do not hide any symptoms; if you feel any discomfort, do not hesitate to tell your physician or pharmacist about it.<\/span><\/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.

Hypertension can be managed with antihypertensive therapy. Monitoring for LVHF is warranted prior to initiation of therapy, every 3 months during therapy, and every 6 months for 2 years after therapy is completed.&nbsp;<\/span><\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Kidney_Complications\"><\/span><span style=\"font-weight: 400;\">Kidney Complications<\/span><span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p>Herceptin may cause kidney complications, leading to a condition called <a href=\"https:\/\/academic.oup.com\/emph\/article\/9\/1\/220\/6284134\">glomerulopathy<\/a>, and can lead to fluid imbalance and additional strain on the heart if left untreated. Glomerulopathy is a syndrome where protein leaks out of the kidneys and is found in the urine. This can be detected by taking a urine test at the doctor\u2019s office.\u00a0<\/p>\n\n\n\n<p>It is essential to screen for hepatitis B prior to initiating Herceptin therapy. Signs of hepatitis B include yellowing of the skin and eyes or excessive tiredness. If you have any of these symptoms, seek medical advice from your physician immediately.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Lung_Damage\"><\/span><span style=\"font-weight: 400;\">Lung Damage<\/span><span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<p><span style=\"font-weight: 400;\">In some cases, Herceptin can potentially cause lung damage and conditions like acute respiratory distress syndrome (ARDS), <a href=\"https:\/\/www.pulmonaryfibrosis.org\/understanding-pff\/about-pulmonary-fibrosis\/what-is-pulmonary-fibrosis\">pulmonary fibrosis<\/a>, pulmonary edema (fluid in lungs), and others. Lung effects may occur <strong>during or shortly after infusion<\/strong>, though delayed reactions have also been reported. Patients with preexisting lung conditions may be at a higher risk.

Infusion reactions may consist of fever and chills, and may also manifest as nausea, vomiting, headache, dyspnea, dizziness, rash, hypotension, and weakness. If shortness of breath, swelling of the mouth or tongue, or drop in blood pressure occurs, the infusion should be stopped immediately.
