** Thanks for contacting with your health concern 1. Remember that suddenly stopping the drug does cause rebound heartburn [nausea, regurgitation of food, sour/acid taste in throat] in the majority of patients and, causes significant digestive distress. 2. clinically significant side effects/long term issues may occur during the treatment with omeprazole and treating physicians should be aware of this phenomenon, and because of the ADR [ adverse drug reaction] is very variable thus you should talk with your attending physician as to how to proceed further. PS. under no circumstances you should stop-change- alter the dosage without first consulting with your doctor.
