Etoposide

Etoposide, sold under the brand name Vepesid among others, is a chemotherapy medication used for the treatments of a number of types of cancer including testicular cancer, lung cancer, lymphoma, leukemia, neuroblastoma, and ovarian cancer. It is also used for hemophagocytic lymphohistiocytosis. It is used by mouth or injection into a vein. Side effects are very common. They can include low blood cell counts, vomiting, loss of appetite, diarrhea, hair loss, and fever. Other severe side effects include allergic reactions and low blood pressure. Use during pregnancy will likely harm the fetus. Etoposide is in the topoisomerase inhibitor family of medication. It is believed to work by damaging DNA. Etoposide was approved for medical use in the United States in 1983. It is on the World Health Organization's List of Essential Medicines. Etoposide is used as a form of chemotherapy for cancers such as Kaposi’s sarcoma, Ewing's sarcoma, lung cancer, testicular cancer, lymphoma, nonlymphocytic leukemia, and glioblastoma multiforme. It is often given in combination with other drugs (such as bleomycin in treating testicular cancer). It is also sometimes used in a conditioning regimen prior to a bone marrow or blood stem cell transplant. It is given intravenously (IV) or orally in capsule or tablet form. If the drug is given IV, it must be done slowly over a 30- to 60-minute period because it can lower blood pressure as it is being administered. Blood pressure is checked often during infusing, with the speed of administration adjusted accordingly. Common are: infusion site reactions low blood pressure hair loss pain and or burning at the IV site constipation or diarrhea metallic food taste bone marrow suppression, leading to: decreased white blood cell counts (leading to increased susceptibility to infections) low red blood cell counts (anemia) low platelet counts (leading to easy bruising and bleeding) Less common are: nausea and vomiting allergic-type reactions rash fever, often occurring shortly after IV administration and not due to infection mouth sores acute myeloid leukemia (which can be treated with etoposide itself) When given with warfarin, it may cause bleeding.
