Hi there and thanks for the post

I am sorry to hear you are feeling so shattered following your 5th cycle of pembrolizumab. As I am sure you are aware pembro can cause tiredness and fatigue and this can sometimes build up with each dose. Do mention to your chemo unit so they are aware and if you notice any other symptoms get yourself checked over, just to make sure nothing else is going on.

Most side effects will ease off after a few days, so hopefully you will start feeling back to your usual self soon.

Take care

Naomi
