I was on Xeloda for 2 weeks. I started having diarrhea on day 10 but it was manageable. But the day after I stopped taking the drug (for my one week break) I started getting worse. The next day I was admitted to hospital. But that doesn't mean this will happen to you. We are all different & respond to medications in different ways. There are a few women on this site who have been taking Xeloda for years & it works for them.
