Dastinib side effects

Categories:

Hi I was on Imatinib for 9 months but the sickness and diahrea couldn’t be controlled so they changed me to 80 mg of dastinib .. I’m not dealing with this well either . I am struggling to go the toilet , I am 80 mg of frusimide and still only go 3 times a day . I suffer with lipodema and since being on this drug it has become worse I have put a stone on within a month of starting it and unable to loose weight . I have now started to have terrible stomach problems , sometimes unable to hold back the bowel movements . Is it possible to go back on imatinib do you know . Or will they change me to a different one again . What happens if I struggle with all of them ..

Hi, you don't say how your bloods are doing but 80 mg is too high it's too toxic .

I had similar problems on imatinib. After 5 years my doctor agreed to switch me to dasatinib 50mg daily. I feel so much better! Digestive issues resolved completely. Other annoyances such as swollen eyelids and weight gain also disappeared. I have been on a low carbohydrate diet since early March and have lost 20 pounds so it may not be entirely due to the switch but it might have helped.

Maybe your dose is too high. You do not need to live this way!

My only complaint with dasatinib is that my hair is thinning, very very slowly, but after a year I definitely notice a difference. If I’m on this drug for the rest of my life I may not have much hair, ultimately. I’m only 60 so it seems sad. But for now I won’t switch because in every other way, dasatinib is much better for me.

Good luck!

Felix,
Your message about 80mg dasatinib being too high-- would you say that is always true or would there be circumstances when a higher dose is called for (early in treatment for example)?
I'm asking because I switched from imatinib to dasatinib and my doc has me on 100 mg.

Hi, less is more with Dasatinib no way would I take 100 mg .I started on 50 mg but very swiftly dropped to 20 mg because it gave me a headache ,then everything was fine .Now I only take 10 mg a day as been undetected for a few years .My doctor who is not a CML expert never agreed with any of my decisions but I took my health into my own hands and luckily I was right .Good luck .

Thank you, this is very helpful. Assuming all is well with my next blood test I will be discussing this with my oncologist!
