What Capecitabine MYX is used for
Capecitabine MYX contains the active ingredient capecitabine.
Capecitabine MYX belongs to a group of medicines called anti- neoplastic agents. Within this group, Capecitabine MYX belongs

It may be prescribed alone or in combination with other medicines used to treat cancer, such as chemotherapy medicines.
The medicine contained in Capecitabine MYX, is converted by the liver and cancer cells to another medicine called 5-fluorouracil
(also called 5-FU).
It is 5-FU that acts to kill or stop the growth of cancer cells.
Your doctor may have prescribed Capecitabine MYX for another purpose.
Ask your doctor if you have any questions why Capecitabine MYX has been prescribed for you.
This medicine is available only with a doctor's prescription.
