Been offered this for late S4 lung with various mets including brain and bone/spine; along with 2 chemo drugs too.
The list of adverse effects is terrifying!!!! The expected life expectancy without some treatment is apparently not at all long...
The oncology consultant didn't actually say much about potential asthma/lung hyper immunologic responses, though I am pretty prone to them, especially in summer allergy season. I do not respond much to inhaled corticosteroids either.
I also have many lifelong allergies, am anaphylactic to some foods, react badly to animal danders and pollens and some volatile organics (like grass sap), and used to have very bad childhood eczema (just occasional contact dermatitis now).
Also a kind of IBS, a chronic MSK pain condition like Fibromyalgia, and the like - not to mention stress and mood swings (post menopausal).
OK, so I'm terrified of taking it - and doctor can only day try it and see (if I even survive the first dose?!)
Really worried about what it's going to do to me, if it's worth it for whatever time or life quality I might get (never mind the chemo).
I don't even feel that bad at the moment.... Most ailments seem to have eased off rather well lately - pre C diagnosis. Typical!!!!
Cheers
Hi Ursula I have not had this drug…… but if you put Pembrolizumab into the search tool 
near the top you will bring up many posts about people’s posts about this drug.
