Hi, my mother has GERD. If she does not take the Omeprazol for 7-8 days she starts to feel worse, the symtoms of reflux. How can she switch from Omeprazol to Pepcid and how do you determine the degree of Gerd she has. Will the degree a,b,c or d effect how to get off Omeprazol and start with Pepcid and how do you get off of Omeprazol in, days or weeks? She wants to do so becuase off the bad side effects that comes with Omeprazol. Is it true that Omeprazol is worse when it comes to side effects than Pepcid. Kind Regards
