​​​​​​​How to take IBRANCE®

IBRANCE® can be taken with or without food. No additional dose should be taken if a dose is missed, and the next prescribed dose should be taken at the usual time. IBRANCE® should be swallowed whole, not chewed, crushed or opened prior to swallowing.1

Available Doses 

IBRANCE® is available in 3 dose levels to facilitate dose modification.1

IBRANCE® Dose Levels

​​​​​​​It is important for patients to start on the 125 mg daily dose as the majority of patients treated with IBRANCE® do not require a dose reduction.2,3

In the PALOMA Clinical Trial Programme ≥1 dose reduction due to adverse events were recorded in 36% of IBRANCE®-treated patients in PALOMA-2 and in 34% in PALOMA-3.2,3

​​​​​​​If further dose reduction below 75 mg/day is required, discontinue IBRANCE®.​​​​​​​1
