IMPORTANT SAFETY INFORMATION
TRODELVY can cause serious side effects, including low white blood cell count and diarrhea:
- Low white blood cell count (neutropenia) can be severe and lead to infections that can be life-threatening or cause death as early as the first cycle of treatment. Your healthcare provider should check your blood cell counts during treatment and may give a medicine to help prevent neutropenia starting in the first cycle of treatment if you have an increased risk for developing low white blood cell count with a fever (febrile neutropenia). Tell your healthcare provider right away if you develop any of the following signs of infection: fever, chills, cough, shortness of breath, or burning or pain when you urinate.
- Severe diarrhea can lead to loss of too much body fluid (dehydration) and kidney problems. Your healthcare provider should monitor you for diarrhea and give you medicine as needed to help control it. If you lose too much body fluid, your healthcare provider may need to give you fluids and electrolytes to replace body salts. If you develop diarrhea during your treatment with TRODELVY, your healthcare provider should check to see if it may be caused by an infection.
- Tell your healthcare provider right away the first time that you get diarrhea during treatment with TRODELVY; if you develop black or bloody stools; if you develop symptoms of dehydration, such as lightheadedness, dizziness, or faintness; if you cannot take fluids by mouth due to nausea or vomiting; or if you cannot get your diarrhea under control within 24 hours.
If you develop serious side effects, your healthcare provider may treat you with certain medicines, delay treatment, lower your dose, or permanently stop treatment with TRODELVY.
Do not receive TRODELVY if you have had a severe allergic reaction to TRODELVY. Ask your healthcare provider if you are not sure.
