Thank you for answering my inquiry. My husband has been on Keytruda every 3 weeks since June 2017, (10 months)
He has lung dancer stage 4 and has been experiencing many of the side effects listed fatigue, loss of appetite, shortness of breath, pain in his back, diarrhea , cough and blisters on his lips and in his nose. He has lost 70+ pounds and is very week and suffering extreme atrophy as a result of loss of appetite we discussed this with the oncologist and felt it would be better if he stopped the treatment for a while but the oncologist insisted these were not side effects of Keytruda but we did not have the treatment 4/27/18 a cat scan will be done 5/2/18 x
