I had the dizziness and lightheadedness on Sprycel as well. It came and went and usually the time frame got shorter the longer I was on the drug.
I thought I left that side effect with Sprycel when I switched to Gleevec, but it happened to me this past January again. I'm going to put a disclaimer first that this could be just coincidental, but it took me two weeks to realize the only thing I had changed was taking my magnesium supplement at the same time as my Gleevec. I started to separate the two by a few hours again and within two days the dizziness stopped.
I never was on Magnesium supplements on Sprycel but when I started Gleevec I had so many muscle cramps and spasms, they finally tested me and I was just below normal on Magnesium. Even with my supplements, I'm at the low end of normal.
Like I said, it could be the side effect was going to go away anyway, but I haven't gotten it again since then (knock on wood).
