What is the most important serious safety information I should know about ADCETRIS?
- PROGRESSIVE MULTIFOCAL LEUKOENCEPHALOPATHY (PML): Patients treated with ADCETRIS can have a rare, serious brain infection called PML. It can cause death. Symptoms can begin at different times after starting ADCETRIS treatment, some within 3 months after the first dose. Call your doctor if you have mood changes, confusion, dizziness or loss of balance, trouble talking or walking, vision changes, or if you feel weak or have weakness on one side of the body. PML could also be caused by other treatments or diseases that made your immune system weaker.
What should I avoid when receiving ADCETRIS?
- Do not take ADCETRIS with bleomycin because of possible serious side effects to the lungs.
What are the other possible serious side effects of ADCETRIS?
A serious side effect can be life-threatening or can lead to death. They may happen during treatment or after your treatment has ended.
Call your doctor right away if you have symptoms of a serious side effect or if your symptoms get worse. If you have a serious side effect, your doctor may delay or stop your ADCETRIS treatment.
- Nerve damage (peripheral neuropathy) that is mostly numbness or tingling in the hands or feet (sensory) and/or weakness in the arms or legs (motor). The nerve damage can get worse with more doses of ADCETRIS. Call your doctor if you have tingling, burning, or numbness in your hands or feet, changes in your sense of touch, or trouble moving your hands or feet.
- Allergic and infusion reactions during infusion or up to 24 hours after your ADCETRIS infusion. Call your doctor if you have fever, chills, rash, or breathing problems within 24 hours of your infusion.
- Blood problems such as a low number of white blood cells with or without fever, a low number of platelets, or a low number of red blood cells.
Your doctor will do blood tests to check your blood cell levels during ADCETRIS treatment. If your levels are too low, your doctor may lower or delay your dose, stop your ADCETRIS treatment, or give you a medicine called G-CSF. G-CSF is meant to prevent you from having a low number of white blood cells.
- Infections such as pneumonia, bacteremia, and sepsis or septic shock can happen with ADCETRIS treatment. Call your doctor if you have a fever of 100.5°F or higher, chills, cough, or pain when you urinate.
- Tumor lysis syndrome can happen if you have a tumor that grows quickly or have many tumor cells in your body.
- Patients with severe kidney disease may have more side effects and deaths than patients with normal kidney function and should avoid treatment with ADCETRIS.
- Patients with moderate or severe liver disease may have more side effects and deaths than patients with normal liver function and should avoid treatment with ADCETRIS.
- Liver injury can happen after the first dose of ADCETRIS or after ADCETRIS treatment is stopped and started again. Call your doctor if you feel tired, do not feel like eating, have upper stomach pain, dark urine, or yellow skin and eyes (jaundice).
- Lung problems. Call your doctor if you have a new cough, a cough that gets worse, or feel out of breath.
- Skin problems called Stevens-Johnson syndrome and toxic epidermal necrolysis can happen. Call your doctor if you have rash, hives, sores in your mouth, or blistering or peeling skin.
- Gastrointestinal (GI) problems related to the pancreas, stomach, intestine, and colon can happen. If you have lymphoma that involves your stomach or intestine, you could have a higher risk of GI perforation (a hole in your stomach or intestine). Call your doctor if you have severe stomach pain, chills, fever, nausea, vomiting, or diarrhea.
- High blood sugar. Your doctor will test your blood during ADCETRIS treatment. If your blood sugar is high, your doctor may give you medicine to control it. Call your doctor if you need to urinate more often, are very thirsty, or have blurry vision.
