HI there,
I have been on Opdivo since 7/2013. I began it through a clinical trial.
Since I have been getting it, the worst side effect is that my thyroid quit working right. I just take a pill every day for that.
I am somewhat fatigued on the day of and the day after a treatment - nothing like I experienced with chemo.
Some friends have had rashes and some nausea. I have had neither.
When I began Opdivo, there was little hope for me. Since I started, my tumors have remained completely stable. (They have NOT gone away, though the radiologist often references them.as scars).
I go every two weeks for the hour long infusion.
Good luck.
