<s>[INST] Hi I already have had my osofigas banded twice but i have a very uncomfortable feelin in the area.I am on Nexium ,I take 20.s and 40,s. but never any more than equal to 3 20,s  At the moment I can.t see my GP until tomorrow.  My main concern is I have to start Kemo next week for Bladder Cancer.  How many Nexium is it Safe to take dayly [/INST] Hi DearWelcome to the board of Health care magic.Nexium is quite safe PPI and it is quite fast acting.40 mg of Nexium per day is quite safe, if required you can twice daily at the maximum. If you still need some more  PPI , then you should think of taking some antacid gel like gelusil or digene gel. These gel can be taken three four times daily or sos.And along with the chemotherapy these all can be taken with out much side effects.Hope your query is answered with satisfaction.Thanks </s>
