Hycamtin (topotecan) is an anticancer treatment option used for small cell lung cancer (SCLC) that comes back (relapsed) after having been treated with first-choice chemotherapy. It’s a convenient pill taken by mouth, usually for a few days each chemotherapy cycle. This medication can raise your risk for infections and bleeds.
Advanced small cell lung cancer (SCLC) that continued to spread after other chemotherapy
Hycamtin (topotecan) is a type of anticancer medication called a topoisomerase I inhibitor. It prevents cancer cells from growing by damaging the cancer cells’ genetic material, which leads to cell death.

You’ll need to get bloodwork done regularly while receiving this medication. Hycamtin (topotecan) can lower your blood cell counts and make you more at risk of bleeding or developing a serious infection. Follow the lab schedule your provider gives you. Depend on your blood cell count, your provider might need to adjust your dose of Hycamtin (topotecan) to minimize your risk of side effects.
Tell your care team as soon as possible if you develop a fever while receiving Hycamtin (topotecan) treatment. This medication can make it more likely for you to get sick. When you’re receiving anticancer medication, sometimes fever can be the first (or only) sign that you’re sick.

Ask your provider or pharmacist if there are any other storage safety instructions for Hycamtin (topotecan).
Tell your provider and pharmacist about all the medications you take, including supplements and over-the-counter medications, so they can help you check for interactions. For example, medications like cyclosporine modified (Neoral) and ketoconazole can raise Hycamtin (topotecan) levels in your body and put you at higher risk for side effects, such as nausea and diarrhea. Before starting any new medications, make sure your provider knows you're taking Hycamtin (topotecan).
If you’re able to get pregnant, you should use birth control while receiving Hycamtin (topotecan) and for 6 months after the last dose. This medication can cause harm to an unborn baby.
If you’re male and have a partner who can get pregnant, you should use birth control measures, such as condoms, while you’re receiving Hycamtin (topotecan) and for 3 months after your last dose. It’s possible for Hycamtin (topotecan) to cause harm to the unborn baby of your female partner if you’re taking this medication.
Hycamtin (topotecan) might affect your ability to have a baby. If you or your partner are thinking about having a child in the future, talk to your provider about your different options before starting Hycamtin (topotecan), such as sperm banking or egg freezing.
Ask your provider or pharmacist about the best way to handle and throw away Hycamtin (topotecan) safely. You or your caregiver should wear gloves when handling this medication. Make sure to wash hands before and after handling. Anticancer medications can be very harmful to people who handle or come into contact with them.
Hycamtin (topotecan) can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.
Hycamtin (topotecan) can cause your red blood cells (RBCs), white blood cells (WBCs), and platelets counts to drop. When the number of these cells are lower than normal, you’re at risk of developing anemia, infections, and bleeding or bruising. In some cases, your blood cell counts might be low for a while. This is because your chemotherapy medications can weaken your bone marrow and affect its ability to make new blood cells like normal.
Your provider will closely check your blood cell counts through routine lab work when you’re receiving Hycamtin (topotecan). Let your provider know as soon as possible if you experience extreme tiredness, rapid breathing, fevers, chills, or bleeding and bruising that doesn’t stop or go away.
Hycamtin (topotecan) can cause diarrhea. This usually happens within 5 to 9 days of treatment. In rare cases, the diarrhea can be severe enough that you might need to be hospitalized. Talk to your healthcare team if you develop diarrhea and be sure to stay well-hydrated. They can recommend antidiarrheal medications, such as loperamide (Imodium A-D) to help manage it. If your diarrhea doesn’t improve or gets worse, let your provider know right away. Your provider might need to lower your dose of Hycamtin (topotecan) or ask you to stop taking it temporarily.
Risk factors: Lung cancer | Scarring of the lungs | Chest radiation |Taking medications that can harm the lungs or cause WBCs to grow (growth factors)
Let your provider know right away if you experience coughing or trouble breathing while receiving Hycamtin (topotecan). This medication can cause interstitial lung disease (ILD), a condition where there’s scarring on the lungs. If you develop these symptoms, your provider will need to examine you to figure out they’re caused by Hycamtin (topotecan) or an infection, and treat you accordingly. If you have ILD, your provider will likely stop this medication.
Based on animal studies, Hycamtin (topotecan) can harm an unborn baby. Because of this risk, regardless of your sex, you should use birth control during treatment with Hycamtin (topotecan) to prevent pregnancy. After the end of treatment, continue to use birth control for at least another 3 months (for males) or 6 months (for females). Let your provider know right away if you or your partner becomes pregnant during this time.
Your provider will calculate your dose of Hycamtin (topotecan) based on your body surface area (BSA, in units of m2), which takes into account your body weight and height.
The typical dose is 2.3 mg/m2 by mouth daily for 5 days (Days 1 through 5) of each 21-day treatment cycle.
