Antibiotics for H. pylori

The exact regimen depends on previous antibiotic exposure, allergies, local resistance patterns and earlier treatment attempts. Taking every component correctly supports eradication and reduces the chance that surviving bacteria become harder to treat.

Helicobacter pylori lives in the stomach lining and can cause ongoing inflammation, peptic ulcers and related complications. Acid suppression helps the stomach lining heal and creates conditions in which the antibiotics can work more effectively.

Treatment plans contain several medicines with different schedules. Some regimens also include a bismuth medicine. A prescriber chooses among them after considering allergy history, interactions and any antibiotics you have taken before.

Request a written schedule showing which tablets are taken with food, which are taken away from food and what to do after a missed dose. Check before drinking alcohol because it can interact with some antibiotics. Tell the prescriber about pregnancy, breastfeeding, liver or kidney disease and all other medicines.

Nausea, loose stools or an altered taste can occur, but severe or persistent effects need medical advice. Do not drop one medicine while continuing the others unless the treating clinician changes the plan. Arrange the recommended follow-up test to confirm that the infection has cleared; feeling better alone cannot confirm eradication.

Seek urgent assessment for vomiting blood, black tar-like stool, sudden severe abdominal pain, fainting, confusion or marked weakness. Obtain emergency help for throat swelling, wheezing or breathing difficulty after a medicine. Contact the prescriber promptly for severe watery diarrhoea, repeated vomiting that prevents dosing, or a widespread blistering rash.

Ask why the selected combination suits your history, how each medicine should be timed and which interactions matter. Confirm when and how eradication will be checked, and ask what the next option would be if the follow-up test remains positive.
