I am new here. Have had CLL for about 4 years. Just started Imbruvica 2 weeks ago with few side effects. The tiredness increased and I am to get my first blood infusion tomorrow. My WBC is 62.4 Lymph 94.9 RBC 2.16 Hemoglobin 7.1 PLT ct 118 I am 85 yrs. Anyone out here have any good things to say about Imbruvica for a person of this age?
