H. pylori Infection
Explore therapies, tests, and supports that clinicians use to manage H. pylori Infection, with practical notes on forms, strengths, and common combinations. This category summarizes medicines and diagnostics often used in care plans, including how regimens differ by components and duration, with US shipping from Canada explained where relevant. Stock and strengths can change over time, so selections shown may not reflect current availability, and any choice should align with your prescriber’s guidance.
H. pylori Infection
Helicobacter pylori is a common stomach bacterium linked to gastritis, ulcers, and some cancers. Many people have no symptoms, while others report burning pain, nausea, bloating, or early fullness. Clinicians confirm infection using noninvasive testing or endoscopy-based methods and then select a regimen based on resistance patterns and prior antibiotic exposure. Treatment aims to clear the organism and reduce the risk of ulcer complications.
Noninvasive testing may include a laboratory breath test or a stool-based assay to confirm active infection. After treatment, clinicians often retest to document successful eradication. You can read about the Urea Breath Test and the Stool Antigen Test to understand how samples are collected, typical timing, and how acid-suppressing medicines may affect results. Work closely with your prescriber to sequence testing and therapy safely.
What’s in This Category
This category outlines common components of multidrug regimens and related diagnostics. You will see acid suppression agents known as proton pump inhibitors, bismuth salts, and key antimicrobials used in combination. Some items are single-ingredient antibiotics, while others are pre-packaged kits designed for coordinated dosing. We also describe noninvasive tests used before or after therapy to confirm results.
You can compare Proton Pump Inhibitors alongside Antibiotics typically paired in regimens. Combination packs such as Pylera Capsules bring multiple ingredients together; your prescriber usually adds a separate PPI. Single agents like amoxicillin, clarithromycin, or metronidazole appear as individual listings in some pharmacies. We note where products differ by tablet versus capsule, typical strengths, and dosing frequency. If you and your clinician choose H. pylori antibiotics, confirm dosing instructions and the plan for test-of-cure.
How to Choose
Selection depends on local resistance patterns, your prior antibiotic exposure, and medication tolerability. Clinicians also consider allergies, pill burden, and whether a combination pack simplifies adherence. Your prescriber may choose a PPI with specific dosing to support acid control, which helps key antibiotics perform better. Many care plans set a follow-up test-of-cure several weeks after finishing therapy to confirm results.
If your clinician recommends H. pylori eradication therapy, discuss the expected duration, food interactions, and whether bismuth is included. Ask how to handle acid suppression before and after testing, since timing matters for accuracy. Review any blood thinners, seizure medicines, or alcohol use, which may interact with certain agents. For context on resistance trends and salvage options, see our Antibiotic Resistance Overview and discuss local data with your clinician.
- Common mistakes: stopping early when symptoms improve; skipping test-of-cure.
- Common mistakes: mixing alcohol with nitroimidazoles; not separating iron or antacids from tetracyclines.
- Common mistakes: staying on PPIs before testing without prescriber guidance.
Popular Options
One representative approach is bismuth-based therapy, which pairs a PPI with bismuth, tetracycline, and a nitroimidazole. This structure spreads activity across different targets and is often used when macrolide resistance is a concern. Pill burden can be higher, but the multi-pronged mechanism is helpful in diverse settings. Discuss whether you need a standard or higher PPI dose with your prescriber.
Another example is a pre-packaged kit containing bismuth subcitrate potassium, metronidazole, and tetracycline, taken with a separate PPI. The fixed-dose design supports adherence by grouping ingredients into scheduled capsules. Check any penicillin allergies if your prescriber is considering alternatives. Some clinicians still use clarithromycin-based triple therapy where resistance rates remain low, especially when prior macrolide exposure is unlikely.
Your prescriber will determine whether H. pylori quadruple therapy or another regimen fits your clinical context. They may consider amoxicillin-based combinations, or switch to different agents if prior therapy fails. When salvage is needed, alternatives and duration adjustments aim to address likely resistance. Adherence, dosing times, and food interactions remain essential to outcomes.
Related Conditions & Uses
This organism is linked to ulcers and chronic inflammation in the stomach lining. When discussing symptoms or complications, your clinician may reference Peptic Ulcer Disease and Gastritis. Clearing the infection can reduce ulcer risk and future bleeding events. Some patients also notice improvement in dyspepsia, which includes upper abdominal discomfort and early fullness.
If your plan addresses H. pylori and peptic ulcer disease, ask about protective strategies during therapy. These can include acid suppression, avoiding NSAIDs, and alcohol limits where appropriate. In some cases, clinicians evaluate iron deficiency or vitamin B12 issues when inflammation is longstanding. After successful treatment, retesting confirms results and supports recurrence monitoring.

Frequently Asked Questions
Which treatments are commonly used for H. pylori?
Regimens typically pair a proton pump inhibitor with two or more antibiotics. Bismuth-based combinations and clarithromycin-based triple therapy are widely used, depending on local resistance and prior exposure. Your prescriber may select a kit or individual components. Treatment often lasts 10–14 days, with a test-of-cure set weeks later to confirm eradication.
Do I need a prescription for these medicines and kits?
Most therapies for this infection require a prescription and medical oversight. Your clinician reviews allergies, interactions, and local resistance data before selecting a regimen. They also plan test-of-cure timing and handle dose adjustments if side effects occur. Over-the-counter acid reducers alone are not sufficient to clear the bacterium.
How do breath and stool tests compare for detection?
Both methods detect active infection and are used widely. Breath testing is noninvasive and sensitive, while stool antigen testing is convenient and scalable. PPIs and antibiotics can affect both, so timing matters. Clinicians often pause acid suppression before testing and repeat a test-of-cure no sooner than four weeks after finishing therapy.
What if clarithromycin resistance is high in my area?
Clinicians often avoid macrolide-based triple regimens when resistance rates are elevated. They may choose bismuth-based combinations or other non-macrolide options. Prior macrolide exposure also matters, even for unrelated infections. If initial therapy fails, a salvage regimen with different drug classes is usually selected after reviewing history and interactions.
Can I use combination packs if I have allergies?
Allergy history is important because many kits include multiple antibiotic classes. Prescribers adjust components when penicillin, tetracycline, or nitroimidazole allergies are present. Bismuth content and PPI selection are also reviewed. Your clinician will propose an alternative plan and schedule follow-up testing to verify eradication while limiting reaction risks.
