I thought I'd got off lightly with imatinib so far - it hasn't been completely uneventful, but I didn't get any of the most common side effects apart from a bit of painful gut cramping at the beginning.
Now at 5 months, I'm suddenly hit with a wall of fatigue that feels as bad as it did when I was first diagnosed with CML, when my main symptom was unreal exhaustion. I felt that the treatment/normalisation of white cell count had actually improved my energy levels, so I'm not sure if this is imatinib finally doing a number on me or whether it's something else. Did anyone else who's been fatigued on a TKI have a delay before it kicked in?
I've also got substantially more hair coming out than prior to imatinib - I think that's actually been going on for several months, but I just ignored it until recently when the hairballs started building up on my clothes. It doesn't come out in clumps, but in the shower there's maybe three-four times more hair coming out than normal and it's all over everything, I have to constantly brush it off. Luckily I have thick hair, but at this rate I'm not sure how long it'll be before it starts showing. I understood that only about 4% of people on imatinib experienced hair loss so again, I'm not sure if this is because of the medication or something else. It would certainly be a coincidence if it was something else...!
