I was taking 30 mg of Prevacid which worked very well- had ot take for bleeding ulcers which dern near done me in- anyway- insurance quit paying and demanded i be given omeprazol instead- they put me on 20 mg. long story short- just got out of hospital recently for duodenal ulcer that had me doubled over in pain for almost 2 weeks- couldn’t stand it anymore- and went in- they put me on 40 mg, 1 pill twice a day mornin night- so far it ‘seems to be’ working, but we’ll see-
I was fortunate to never experience severe pain from the duodenal ulcer. I did have some excruciating pain in my esophagus. The acid reducer fixed that. Hopefully you are getting better with acid reducer. It's an unpleasant experience.
