How long does Xeloda (capecitabine) stays in the body after 6 months taking 7 pills daily?

Not sure. I am not sure about your question. I think that you are asking how long it stays in the system after 6 months of use. A typical schedule in 2 weeks on and 1 week off. The drug is quickly eliminated from the body. Kidney disease can affect the elimination. Side effects in the skin of hands and feet can take a few weeks to heal after the drug is stopped. If not helpful clarify the question please.
