I've been on Gleevec since December 2006. Through Trial and Error I have found the following very helpful in keeping the SE manageable.
NEVER be hungry when you take it. If you are very hungry eat small snack/meal before your main meal - so I found this left out breakfast. MAKE SURE CARBS AND NON-SPICY PROTEIN is in the meal that you take Gleevec. MAKE SURE YOU DRINK ENOUGH WATER - I need at least 4 to 5 20-oz glasses (I noticed my cramps decrease when I'm very hydrated). LIMIT PHYSICAL ACTIVITY RIGHT AFTER TAKING PILL - anything that causes the pill to digest faster tends to exaggerate the SE for me - which leads me to - NO SWEET DESSERTS FOR 2 HOURS AFTER TAKING GLEEVEC - I can have dessert before my meal (if meal has lots of protein and carbs) or 2 hours after, but not before that. WATCH YOUR SODIUM INTACT - I retain less fluid if I watch my sodium intake.
This isn't 100% guaranteed, so if do feel queasy - SALTINE CRACKERS AND GINGER ALE (preferable with real ginger). In the beginning I was eating SWEETZELS GINGER SNAPS, if the pill made me queasy, and they helped a lot, only needed a couple.
For Fatigue - It's there. I have noticed a slight improvement in the last couple of months - things that I have changed: REDUCED STRESS, REDUCED CAFFEINE (so I can listen to how tired my body really is, and avoid getting too overtired - takes too long to recover), SWITCHED TO DINNER TIME TO TAKE THE GLEEVEC - (I was taking it at lunch, since that is my preferred large meal, but was tired every afternoon. ) EXERCISE - I've tried various things over the years, but back in March I started going to the gym with my husband and girlfriend 3 days a week. At first I just had to be there for an hour doing whatever I could for as long as I could (even if it was just walking slowly around the gym, or taking a long break after just doing one exercise, it was more than I was doing at home). It took over 6 months before I could really feel like things were showing any signs of improvement (have trouble moving for an hour, some days it's half and hour and I'm done - but I'm moving). I had tried exercising with a specific goal in mind and it just made me more tired. My goal this time was strictly to improve my stamina, I wasn't trying to walk a certain distance, I just didn't want to be as tired.doing day to day things
Oh and MENTALLY - some days are foggier than others, ESPECIALLY when I'm tired. I've found mentally stimulating games have helped my concentration (Lumosity's free games daily, etc).
Sorry for the length, and hope that some/all of these things help. I just tried to tackle each side effect as they appeared and find a way to make the best of them. I've been lucky and right now it's pretty much working for me, and hope you find a similar balance. .
