Why is resistance important?

About 8 out of 10 Americans treated for H. pylori infection in the United States are prescribed a regimen that includes the antibiotic clarithromycin.4 Over time, people may develop clarithromycin resistance, which can then be associated with a greater likelihood of treatment failure when clarithromycin-containing regimens are employed.5

Why treatment success is important:

Another concern is the potential for allergic reaction to prescribed antibiotics. Along with clarithromycin, the antibiotic amoxicillin, a form of penicillin, is included in the prescription for 8 out of 10 patients being treated for H. pylori.4 Penicillins can cause an allergic reaction in some people. It isn't clear why some people develop penicillin allergy and others don't. You aren't born allergic to penicillin, but you can develop penicillin allergy once you've been exposed to the drug. After that, re-exposure to penicillin or related antibiotics can trigger an allergic reaction.6
