Capcetabine

Anyone any issues with taking oral capcetabine? I had 6 rounds of intravenous chemo then surgery then radiotherapy and thought treatment was over but I'm now to get 9 sessions on capcetabine in tablet form as a precaution, they have removed tumour and I'm cancer free as far as they know but its was still grade 3 triple negative and im high risk so this is to help chances or no recurrence. Im 43 yrs old. Wondering and hoping its loads easier
