Thanks to everyone on here for all your support just an update: my dad has CLL but it got worse he had to have a blood transfusion. Well his treatment started with Chlorambucil tablets he took 11 each morning for so long and he didn't have any side effects. Then on 27th April he went into City Hospital Nottingham outpatients for Obinutuzumab which was given through IV and this was a taster session, has soon has they started it he started having a reaction he said he had pins & needles then started shacking un-controllably all over they stopped the IV for half an hour my dad said it was like being out in the cold. then started again after a while his temp. Went up so they stopped it again gave him paracetamol and waited for a while then started it again he finished that bag. He had to go back the next day 28th April, and he was given a full bag of Obinutuzumab the only side effect was high temp. He was given the Chlorambucil tablets again he had to go for Obinutuzumab again a week later this time he had an high temp. Again They gave him 2 paracetamol He has had 1 more round of chemo with no problems & is feeling a lot better now his night sweats are a lot better he said he feels better sleeping in a t shirt & it only gets damp now my dad feels more himself. He has to go next Thursday for more Obinutuzumab and then he will have the tablets again and after that he will just have to go monthly I hope this helps other people.
