That link leads to something called "Magic Mouthwash" and it was the only thing that gave me any relief from bad mouth sores. It'll have to come from a compounding pharmacy. There's a good chance the Abraxane will give him increasingly bad neuropathy in his feet, lower legs and fingertips. Look up cold therapy booties and mittens that can be used before his next infusion to help prevent the neuropathy. I tolerated Folfirinox pretty well, but Gemcitabine/Abraxance was rough as a cob to tolerate in my case. Good luck.
