meds for gastric reflux

  My husband has had Barretts for 8 years and has an endoscopy every 2 years to assess malignancy.  No malignancy has been evident.    He has watched his diet and alcohol intake and has been on the Rx Pepcid (40mg.) 2x daily for the 8 years. This has been quite successful in controlling the symptoms.
  His Internist recently prescribed Prilosec and said if it was successful he might take him off the Pepcid.  I understand that Pepcid is an acid blocker and the Prilosec is a neutralizer.  What is your opinion regarding this change.
  my husband would like to discontinue the Pepcid as we heard recently that long term use could affect testosterone level and  my husband has experienced evidence of that. any comments on this?
  Thank you for your help
