5 Warnings and Precautions

5.2 Myelosuppression

Additions and/or revisions underlined:

New or worsening Grade 3 or 4 neutropenia and thrombocytopenia occurred in 49% and 22% of patients who received ONUREG, respectively. Febrile neutropenia occurred in 12%, and sepsis was reported in 6%, including 1 fatal case. A dose reduction was required for 7% and 2% of patients due to neutropenia and thrombocytopenia, respectively. Less than 1% of patients discontinued ONUREG due to either neutropenia or thrombocytopenia.

Monitor complete blood counts and modify the dosage as recommended [see Dosage and Administration (2.2, 2.3)]. Provide standard supportive care, including hematopoietic growth factors, if myelosuppression occurs.


6 Adverse Reactions

6.1 Clinical Trials Experience

Additions and/or revisions underlined:

What are the possible side effects of ONUREG? ONUREG can cause serious side effects, including:

  • New or worsening low white blood cell counts (neutropenia). New or worsening low white blood cell counts can be severe during treatment with ONUREG. If your white blood cell counts become very low, you are at increased risk for infections, including a severe infection of the blood called sepsis that can lead to death. Your healthcare provider will check your white blood cell counts before and during treatment with ONUREG. Your healthcare provider may prescribe a medicine to help increase your white blood cell count if needed.

Tell your healthcare provider right away if you get any of the following symptoms:

. . .

  • lightheadedness or dizziness
  • shortness of breath
  • confusion or grogginess
  • fast heartbeat

. . .

The most common side effects of ONUREG include:

. . .

  • low white blood cell counts

  • sore throat and runny nose
  • skin infection
