Topotecan can harm an unborn baby or cause birth defects if the mother or the father is using this medicine.
- If you are a woman, do not use topotecan if you are pregnant. You may need to have a negative pregnancy test before starting this treatment. Use effective birth control to prevent pregnancy while you are using this medicine and for at least 6 months after your last dose.
- If you are a man, use effective birth control if your sex partner is able to get pregnant. Keep using birth control for at least 3 months after your last dose.
- Tell your doctor right away if a pregnancy occurs while either the mother or the father is using topotecan.
This medicine may affect fertility (ability to have children) in both men and women. However, it is important to use birth control to prevent pregnancy because topotecan may harm the baby if a pregnancy does occur.
You should not breastfeed while using topotecan, and for at least 1 week after your last dose.
How should I use topotecan?
Follow all directions on your prescription label and read all medication guides or instruction sheets. Use the medicine exactly as directed.
Topotecan capsules are taken by mouth, with or without food. You may need to take two different colored capsules at one time. Make sure you know the difference between capsules because one contains 4 times as much topotecan as the other, even though they may look the same in size.
If you vomit after taking a topotecan capsule, do not take another dose that same day.
Do not use a broken or opened capsule. The medicine from a broken pill can be dangerous if it gets in your eyes or on your skin. If this happens, wash your skin with soap and water or rinse your eyes with water for at least 15 minutes. Then call your doctor.
Store topotecan capsules in the refrigerator and protect them from light.
Topotecan injection is given as an infusion into a vein. A healthcare provider will give you this injection. Tell your caregivers if you feel any burning, pain, or swelling around the IV needle when topotecan is injected.
Topotecan can lower your blood cell counts. Your blood will need to be tested often. Your cancer treatments may be delayed based on the results.
Your doctor will determine how long to treat you with topotecan.
What happens if I miss a dose?
Take the medicine as soon as you can, but skip the missed dose if it is almost time for your next dose. Do not take two doses at one time.
Call your doctor for instructions if you miss an appointment for your topotecan injection.
What happens if I overdose?
Seek emergency medical attention or call the Poison Help line at 1-800-222-1222.
Overdose symptoms may include skin rash or other irritation, nausea, vomiting, diarrhea, or mouth sores.
What should I avoid while using topotecan?
Avoid driving or hazardous activity until you know how this medicine will affect you. Your reactions could be impaired.
Avoid being near people who are sick or have infections. Tell your doctor at once if you develop signs of infection.
