That is correct. Usually when a med says not to take with antacids it is because of the magnesium or calcium in the antacids. Zantac and protonix reduce acid and should not effect the antibiotic. Whenever I am on a Z-pack I take the antibiotic BEFORE I take my Prevacid. The antibiotic has a hard coating and I figure some stomach acid might help break it down better. Don't know it that is true, but it's my theory.
