A serious side effect of Kymriah is called cytokine release syndrome, which causes fever, chills, trouble breathing, vomiting, and other symptoms. Your caregivers will have medication available to quickly treat this condition if it occurs.
Kymriah can also cause life-threatening nerve problems. Tell your caregivers or seek emergency medical attention if you have problems with speech, problems with thinking or memory, confusion, or a seizure.
