What is typical dosage of xelota for colorectal radiation?

The typical dosage of Xeloda (capecitabine) for colorectal cancer when combined with radiation therapy is 825 mg/m² orally twice daily2. This dosage is adjusted based on individual factors like body surface area, treatment goals, and tolerance. Always consult your healthcare provider for personalized guidance.

I completed my stage 3 radiation treatment three months ago and the 825 mg/m² orally twice daily was what was prescribed for me - I'm 6' 200lbs.
