I'm wondering if anyone can let me know of any side effects they've had on Keytruda/pembrolizumab?

I had issues receiving my first dose on Friday and was medicated with steroids and antihistamines at the time. Since then I've had breathlessness/cough and asthma like feeling in my chest.


Unfortunately ever since being diagnosed with cancer my immune system has turned into the Hulk and I've developed allergies to all kinds of medications. Its like playing chicken with a pharmacy. If anyone has had this sort of this happen also would be great to hear from them!

Hey Coralyn,

My spouse  had immune therapy  keytruda and he took it more than 1 year after brain tumor Surgery and he had lot of crazy cough at the night and couldn’t sleep so doc prescribed some med and but that med was missing up his blood work too. but he was very patient and was still taking immune therapy  probably 6 months after his body adjusted better. But he felt always like he had some kind of cold or flu. Had runny noise light cough sore throats everyday etc... 

While getting treatment he had seizure and that cancer came back again and he had surgery again and immune therapy didn’t work well with him and his brain frontal lobe had a lot of necrosis so he stopped it. 
After he has again surgeries some other area and trying all kind of things now. 

good luck! 
stay safe .
