Patient Education

Topotecan


Topotecan is used to treat small cell lung cancer (a type of cancer that begins in the lungs) that was successfully treated with a different chemotherapy medication but has returned no sooner than 45 days after the last dose of the first chemotherapy medication was taken. Topotecan is in a class of medications called topoisomerase I inhibitors. It works by killing cancer cells.

Topotecan Injection


Topotecan injection is used to treat ovarian cancer (cancer that begins in the female reproductive organs where eggs are formed) and small cell lung cancer (a type of cancer that begins in the lungs) that have spread and did not improve after treatment with other medications. It is also used together with other medications to treat cervical cancer (cancer that begins in the opening of the uterus [womb]) that has not improved or has come back after other treatments. Topotecan is in a class of medications called topoisomerase type I inhibitors. It works by killing cancer cells.

Cancer Chemotherapy


Normally, your cells grow and die in a controlled way. Cancer cells keep growing without control. Chemotherapy is drug therapy for cancer. It works by killing the cancer cells, stopping them from spreading, or slowing their growth. However, it can also harm healthy cells, which causes side effects.

You may have a lot of side effects, some, or none at all. It depends on the type and amount of chemotherapy you get and how your body reacts. Some common side effects are fatigue, nausea, vomiting, pain, and hair loss. There are ways to prevent or control some side effects. Talk with your health care provider about how to manage them. Healthy cells usually recover after chemotherapy is over, so most side effects gradually go away.

Your treatment plan will depend on the cancer type, the chemotherapy drugs used, the treatment goal, and how your body responds. Chemotherapy may be given alone or with other treatments. You may get treatment every day, every week, or every month. You may have breaks between treatments so that your body has a chance to build new healthy cells. You might take the drugs by mouth, in a shot, as a cream, or intravenously (by IV).
