Welcome, Sunshine! I had various minor, but irritating, side effects when I first switched from Gleevec to 100 mg. of Sprycel on Oct. 9, 2009 (but who's keeping track ), but amazingly, no headache. Burning sensation on my face and upper arms and legs. Even though they looked perfectly normal, I thought they should be bright red to match the sensation. My first night was horrid, won't go there. Then, on Thanksgiving Day I just didn't feel good and that's when the malaise set in. I would want to hide under my desk at work because I felt so horrible. I took my pill with tears in my eyes on many days. I remember telling my husband on several occasions that I was afraid I would die. Then, after about 4 months, I would start to feel "normal" for a few days at a time and then after a couple more weeks I was back to CML normal.
I didn't recognize it at the time for what it was but I think I was just incredibly fatigued. Don't let the doctors and nurses try to make you feel like an idiot. I breezed right through Gleevec, loved it, until my liver decided it didn't. These are very powerful drugs that we all seem to experience in our own ways.
Marnie and I developed pleural effusions around the same time, about 2.5 years in. After they resolved we both went on 50 mg. and have done very well. She developed another PE just recently, knock wood, I haven't. Maybe, I won't (I hope).
I don't know anyone that hasn't had issues of one sort or another with the drugs. You decide what you can live with and you decide what's the deal breaker and you discuss the deal breakers with your onc and try to figure out a way to make it easier.
My onc trusts me when I tell him about things I can't tolerate. I don't go whining to him with every little thing, I save that for all my BIFs (Best Imaginary Friends) on here!
You will probably do great on Sprycel! When you don't feel good, own it, and to hell with what anyone else thinks!
Good luck!
