To treat H. pylori a doctor typically prescribes two antibiotics such as amoxicillin and tetracycline, a proton-pump inhibitor such as Prevacid or Prilosec, bismuth subsalicylate, and a histamine blocker such as Zantac or Tagamet, explains WebMD. Treatment often requires taking up to 14 pills per day for several weeks.
Other antibiotics sometimes used to kill Helicobacter pylori, or H. pylori, bacteria include clarithromycin, metronidazole and tinidazole, reports WebMD. Potential proton-pump inhibitors and histamine blockers used to reduce the production of acid in the stomach include Nexium, Protonix, Fluxid, Pepcid and Axid. If the stomach has ulcers caused by H. pylori, it is necessary to avoid non-steroidal anti-inflammatory drugs such as ibuprofen and aspirin because they irritate the stomach.
H. pylori are bacteria that enter the body through water, food, utensils or the saliva of an infected individual, explains WebMD. Once ingested the bacteria live in the digestive tract where damage is done to the stomach lining or upper small intestines, eventually causing acid to leak, which sometimes results in ulcers. Ulcers have the potential to become infected, to bleed or to obstruct the passage of food through the digestive system. In some cases an H. pylori infection is a precursor to stomach cancer, although approximately two-thirds of humans have the bacteria in their bodies, and most are symptom and ulcer-free.
