"I had ablation surgery three weeks ago and have been on Pradaxa 150mg twice a day ever since.  During the first week, I had a constant sour stomach and my surgeon suggested Prilosec. It takes a few days before Prilosec kicks in so I took Mylanta until it did.  My second and third weeks were much easier but now that I'm starting my fourth week, the constant sour stomach is back.  I still take Mylanta between meals but it only helps a little.  I take Pradaxa during meals with a full glass of water.  I have to stay on this medicine five more weeks.  Any suggestions would be appreciated."
