Oral, once-daily dosing
IMBRUVICA® is available in two formulations, including a single tablet, once-daily option
The recommended dose for mantle cell lymphoma (MCL) is 560 mg per day, administered orally as either one 560-mg tablet or four 140-mg capsules
- IMBRUVICA® tablets or capsules should be swallowed whole with water at approximately the same time each day
- Do not open, break, or chew the capsules. Do not cut, crush or chew the tablets
- Patients should take a missed dose of IMBRUVICA® as soon as possible on the SAME DAY, with a return to the regular schedule on the following day
- If a full day of treatment is missed, patients should NOT take extra doses to make up for the missed dose
- Patients should NOT take more than their prescribed dose per day
- Instruct your patients to call their healthcare provider or go to the nearest hospital emergency room right away if they take too much IMBRUVICA®
Once-daily dosing is necessary to ensure inhibition of BTK enzymatic activity1
Inhibition of BTK by IMBRUVICA® has a disruptive effect on 3 key B-cell processes as shown by in vitro and in vivo studies1:
- Inhibits survival and proliferation1-6
- Inhibits adhesion1,6-11
- Modulates chemotaxis and trafficking1,5,7,9,11-14
Correlation to clinical effect has not been established.
