I have been prescribed Pantoprazole 40 mg. After my endoscopic exam last Tuesday, it was suggested that I increase my once a day 40 mg dose to twice a day. I have been having stomach pains since Thursday morning, and when I called the medical assistant whose phone number I was given to use if necessary after the procedure I told her that I normally eat a banana first thing in the morning, but on Thursday and today my stomach started to ache/cramp soon after I ate the banana. It was suggested that I take the pantoprazole 30 minutes before I eat anything, and to wait to eat the banana until after I have eaten something such as oatmeal, as bananas have a lot of potassium. That is the reason I started eating one or two bananas a day, as I have been diagnosed with low potassium. Can you verify this information for me--take the pantoprazole 30 minutes before I eat anything, and wait to eat a banana until after I have something else in my stomach?
