Topotecan, sold under the brand name Hycamtin among others, is a medication used to treat ovarian cancer, cervical cancer, and lung cancer.[4] It is used when other treatments have failed.[4] It is given by mouth or by injection into a vein.[4][1]
Common side effects include low white blood cells, low platelets, fever, low red blood cells, nausea, diarrhea, mouth sores, and hair loss.[4] Use during pregnancy may harm the baby.[1] It is a topoisomerase inhibitor and works by interfering with the ability of cells to make DNA.[1]
Topotecan was approved for medical use in Europe and the United States in 1996.[4][1] It is available as a generic medication.[5] It costs about 127 USD for 4 mg for injection in the United States as of 2021.[6] In the United Kingdom 10 tablets of 0.25 mg costs about £75.[5]
