Hi Jan56,
I hope you will have an easier time on it, some people do. They can also reduce doses if needed.
I was told by the pharmacist when I picked up my first dose that diarrhea was common. Mine was bad enough that they reduced the dose. People can have hand or foot problems, in my case the bottom of my feet peeled , at that time they wanted me to stop, but I asked if I could take a lower dose. I did okay with that. Since our TNBC is not hormone driven this is a drug they use for us. Even with those reactions it was worth taking it since our cancer is a rarer form and they don't know alot about it, although I think that is changing now, more studies are being done.
Sending you hugs and hoping the best for you.
