What is the difference between Zantac and Omeprazole for GERD? Details: I took Omeprazole (generic for Prilosec) for 12 years when I found that I was having some horrible side affects such as Urinary Tract Infections, Sinus Infections, bone pain, shortness of breath, nausea in the morning, etc. I slowly stopped taking the above and am now on Zantac #150 each morning an hour before my meal.
