Hello Everyone, came to this thread as I desperately search for some help regarding Keytuda induced stomach / GI issues.

So far, I had 6 Keytruda infusion (200ml) + chemo.
Post chemo, Keytruda alone about 5 infusions (full dose of 400ml).

This very last one about 3 weeks ago created a havoc on my stomach. A day after, started to experience stomach pain post meal. Managed it with home remedies like mint, carom seeds with little salt for enhanced digestion. About a week later reported to Dr. as no relief was on sight. An Rx of Prilosec (20mg for 15 days was advised stating it seems like a gastritis issue.
Took this Rx for about 13 days & 2 to go yet no relief. Matter fact, discomfort is bit more.
There is a loss of appetite, no desire to eat food. Many times just forcing (pushing food in my mouth) myself to eat a bite.
Reported my issue with update again. This time being advised on trying Reglan, an anti-nausea med that was given for 3-4 days post chemo … justification, looks like my stomach is not getting emptied quick. BTW, never had any issues eating food in large qty before.

My question, has anyone else similar issue? If yes, how did you resolve it?
Any help will greatly appreciated.
