"I had a bad side effect from this drug, got chills, my kidneys about shut down, had heart problems, skin got red as I ever seen it. The oncologist knew this was going to happen, so I felt he was using me as a lab rat. Hard to trust any of these drugs today or the doctors. I guess that's why they call it a practice."

"As other reviewers shared, this drug causes severe side effects - and for my mother it was because she was not tested for DPD deficiency before her infusion. Had she been tested for DPD deficiency before treatment, she would have been given a lower dose, and then she would be alive today. DO NOT TAKE this medication (5FU) without the results of a DPD deficiency test. This is a DPYD gene test that can be done by blood draw or spit depending on where you get your cancer care. Don't take no for an answer - get a DPD deficiency test before infusion. Dosage can be reduced based on your enzyme function per CPIC guidelines for DPYD. The Association for Molecular Pathology also just published guidance for labs with which variants should be tested for the DPYD gene. Patient knowledge is powerful."

"I had a heart attack after using this product. I was in the cardiac unit for 4 days and ended up having an angiogram. My heart was not blocked, it was this drug."
