Sorry to hear. I had 5-FU infusions, and know it's a strong chemo. Speak with the doctor, maybe a lesser dosage, less frequently, and prophylactic counter measures that would be effective can be given. Too bad about the co-pay too, there are co-pay prescription assistance programs out there, and the pharmaceutical companies themselves may have assistance programs for the uninsured, underinsured, if you find time, and this drug is going to be continued.

I hope you, and your mom find some relief.
