Hi DebbyO I'm sorry you are having a tough time with Keytruda. I was on Keytruda
prior to surgery ( 7 treatments) but I was not NED after surgery and they stopped it. However I was lucky to feel fine on it, as you know it is different for everyone. Did you talk to your MO about it? Maybe they can give you some meds to counteract the GI issues. I agree with staying on Keyruda , I was very upset when I could not continue on it so I understand your concern. I am hopeful your MO will be able to manage your side effects.
Best wishes.
