Side effects to watch for

Serious side effects

Each person responds differently to VENCLEXTA in combination with azacitidine, or decitabine, or low-dose cytarabine. Side effects are a real possibility and VENCLEXTA can cause serious side effects, which include:

Tumor lysis syndrome (TLS)

TLS is caused by the fast breakdown of cancer cells. It can cause kidney failure, the need for dialysis treatment, and may lead to death. Your healthcare provider will do tests for TLS, so keeping appointments for those tests is important. To help reduce TLS risk, you will receive other medicines before starting and during treatment with VENCLEXTA. You may also need to receive intravenous fluids into your vein.

Tell your healthcare provider right away if you have any symptoms of TLS during treatment with VENCLEXTA, including:

  • Fever
  • Chills
  • Nausea
  • Vomiting
  • Confusion
  • Shortness of breath
  • Seizures
  • Irregular heartbeat
  • Dark or cloudy urine
  • Unusual tiredness
  • Muscle or joint pain

Low white blood cell counts (neutropenia)

Low white blood cell counts are common with VENCLEXTA but can also be severe. Your healthcare provider will do blood tests to check your blood counts during treatment with VENCLEXTA and possibly pause dosing.

Infections

Death and serious infections such as pneumonia and blood infections (sepsis) have happened during treatment with VENCLEXTA. Your healthcare provider will closely monitor and treat you right away if you have a fever or any signs of infection during treatment with VENCLEXTA. Tell your healthcare provider if you have a fever or any signs of an infection during your treatment with VENCLEXTA.

Some people may experience other side effects.
