My 87 Year Old Mum Has Started Imbruvica 2 Months

My 87 year old mum has started imbruvica 2 months ago. She has had CLL for 26 years. She had a lot of bruising but that seems to be better than it was. Also mouth ulcers which have cleared. She has glucoma which had a reading of 15 for some years. Last week it was 22. Not sure why. We thought mum had dermatitis but one patch on her face is now sore and weeping. Not sure why with this or if these things are coinsidence. Her spleen is back to normal as is her hemoglobin which is very pleasing. She is very tired but was tired before all this. She takes 3 tablets a day. Also would taking Berocca be a problem as I thought it might give her a boost? I would appreciate your input.
