I've just been given free sample bottles 15 doses, Dexilant; I have been experiencing bloating, nervous/sore stomach, my stomach is tender to the touch in the upper region. I had a CT scan week ago and it proved negative, I have been taking Omeprazole, 20 mg, once a day for years. I also take Lisinopril, 20 mg, once a day, and Metoprotol, 50 mg, twice a day. Should I begin taking Dexilant, 60 mg, once a day and discontinue Omeprazole for the time being until I use up the samples? My e-mail is YYYY@YYYY . Thank you for your response.
