Be careful about the dose of B6. Amounts over 200 mg can be toxic in some persons, so be sure to check with your oncologist before taking this vitamin.
I've been in a clinical trial using Sutent to control my metastisized thyroid cancer for about a year. I've been taking Vitamin B-6 (200 mg daily with my doctor's permission) for the last few cycles. It helps alot with the peeling and flaking, although it doesn't help me much with the pain.
Udder Creme, Bag Balm, and Gold Bond Foot Creme help some with the peeling and pain as well. Using an ice pack is a big help, too.
