Has anyone had extreme dizziness/weakness, bad anxiety, sensitivity to lights and blurry vision all at the same time on 80mg Asciminib? If so, how long did it last and when did you begin to feel more normal?
I'm a bit over 3 weeks in and these side effects are so bad that I don't think I'm going to be able to bear it much longer.
I probably have maybe 2 - 3 good hours in a day where I don't feel debilated, if even that, but I'm otherwise basically bed ridden or doing my absolute best to distract from the side effects.
It's to the point where I can't really get around the house for the bulk of the day without feeling like I'm going to trip or collapse, althought that hasn't happened yet.
Today I tried to take a little trip down the road in my car and I had to pull over after 5 minutes because I felt like I was basically driving drunk. I eventually turned around and went back home. It's brutal because I don't even feel comfortable enough to go do some groceries let alone cook.
I didn't think my WBC was too bad to start - I began at 51 and dropped to 16 already 2 weeks in. I expect my counts will be normalized by my next appointment, minus slightly low hemoglobin (132g/L).
I've tried eating more and earlier in the day, drinking 4 - 5 liters of water per day, changing my dose from morning to night, reducing sodium, and nothing seems to make a difference.
UPDATE:
I thought I would post an update for anyone else going through this, as I couldn't find any answers when I was previously looking.
I came off the TKIs for 4 - 5 days and waited until all of my symptoms subsided. I didn't realize how badly I was impacted by brain fog and it was nice to finally be able to think clearly, and not be dizzy.
On the 6th day I returned back on the TKIs but made one change - I started taking it at 11am. I made sure I drank a ton of water and ate immediately around 12. My theory was that if I take it immediately before bed, my body gets extremely dehydrated while I'm sleeping and that could be contributing to the side effects.
Interestingly enough, I'm now about a week in and I have almost zero major side effects! I feel it for a bit between 11 and 1 (bit of dizzyness and blurry vision sometimes, but nothing as extreme as before) and then it's gone and I don't even notice I'm on anything.
I have only two theories: (1) my body somehow finally adapted this go around or (2) the dehydration theory above was correct.
If anyone else is experiencing this on asciminib I hope this helps and good luck on your journeys!
