What is inside the strip your doctor prescribed, how the course usually works, and what the newly approved vonoprazan kit changes.
An H pylori kit is a pre-packed treatment that usually combines one medicine that lowers stomach acid with two antibiotics that kill Helicobacter pylori, the bacterium behind most stomach ulcers. The exact medicines and doses vary by product, and the course usually lasts 7 to 14 days, as your doctor prescribes.
Few people realise that “HP kit” is not one medicine. Companies sell kits with different antibiotics and acid blockers, sometimes under the same brand name. And in September 2026, India approved a new kit built around vonoprazan, a stronger kind of acid blocker. This guide focuses on kits commonly sold in India, with treatment advice based on current international guidelines.
Quick Answer
- What It Is: Many pre-packed kits hold one acid reducer and two antibiotics, often as one day’s treatment per strip.
- How Long: Some older kits are labelled for 7 days, while current guidance commonly recommends 14. Follow your prescription.
- Key Rule: Finish every strip, even if the pain settles in a few days.
- After the Course: A breath or stool test at least 4 weeks later confirms the infection has gone.
What Is an H Pylori Kit?
Why Three Medicines Together
H pylori treatment often uses more than one antibiotic to improve the chance of clearing the infection and reduce the impact of antibiotic resistance. The acid-reducing medicine also supports treatment and helps the stomach lining heal.1 Guidelines describe the infection as a common cause of indigestion, peptic ulcers and, over many years, stomach cancer.2
What “Kit 6 Tablet” Means
In kits such as Zosa HP Kit, a strip holds six tablets, two of each medicine, and is designed as one day of treatment: one of each in the morning and one of each in the evening.3 Designs vary, so check your own pack.
Not All HP Kits Are the Same
Pharmacy listings show how much the contents vary. Even one brand, Pylokit, is sold in two versions with different medicines inside.4
Good to Know
Because the antibiotics differ, one HP kit cannot simply be swapped for another. Kits with amoxicillin are unsuitable if you are allergic to penicillin, and each kit carries its own warnings. If the pharmacy offers a substitute, check the salt names with your doctor first.
The New Vonoprazan Kit Approved in 2026
On 21 September 2026, Akums Drugs and Pharmaceuticals announced that it had received DCGI approval for an adult H pylori combikit that packs vonoprazan 20 mg, clarithromycin 500 mg and amoxicillin 1,000 mg into one organised pack.5 Reports describe it as taken twice a day for 14 days.5 The official approval document, brand name and price were not publicly available at the time of writing.
What Is Vonoprazan?
Older kits use proton pump inhibitors such as omeprazole. Vonoprazan is a potassium-competitive acid blocker, a newer class that suppresses acid faster and more strongly. It has been approved in India since May 2024 for uses that include helping to clear H pylori.1
How Does Vonoprazan Compare With Older Kits?
Research is encouraging. A review of 10 trials and 17 observational studies found vonoprazan regimens worked at least as well as older acid-blocker regimens, and better in some patients whose bacteria resisted clarithromycin.1 The American College of Gastroenterology also prefers the vonoprazan triple combination over the older version when clarithromycin sensitivity is unknown.2 Your doctor will still choose the regimen based on your history and any earlier treatment.
Part of the reason is stronger acid control. In a study of healthy adults, vonoprazan kept stomach pH above 4 for much longer each day than lansoprazole 30 mg, the acid reducer used in Pylokit.6

Do You Need a Test Before Taking a Kit?
Usually, yes. An H pylori kit should not be taken just for routine acidity, and doctors usually confirm the infection first using a urea breath test, a stool antigen test or a small biopsy taken during endoscopy.7 Taking antibiotics you may not need also feeds resistance. If acidity keeps returning, ask your doctor whether H pylori testing makes sense.
How an H Pylori Kit Is Usually Taken
The exact timing depends on the medicines in your kit, so follow your pack and prescription. Leaflets for common kits advise one of each tablet in the morning and one of each in the evening, often before a meal, swallowed whole with water.3, 4 Keep to the same times each day.
How Many Days Should You Take It?
7 Day Courses
Some older Indian kits are labelled for 7 days.3
14 Day Courses
Current guidelines recommend 14 days for several preferred treatment regimens, and the exact duration depends on the medicines used. The new vonoprazan kit is reported as a 14 day course.2, 5 If your doctor prescribes 14 strips, take all 14. Stopping early because you feel better raises the chance that the infection comes back.4
Side Effects of H Pylori Kits
Common and Usually Mild
Pharmacy leaflets list nausea, loose motions, stomach pain, headache and a bitter or metallic taste as common effects.4 Side effects depend on the medicines in your kit, so check the leaflet for your product. Most settle once the course ends.
When to Call Your Doctor
Contact your doctor promptly for a rash, swelling of the face or lips, breathing difficulty, or severe watery diarrhoea lasting days. These can signal an allergy or a more serious reaction.
Who Should Be Careful
Before starting a kit, tell your doctor about:
- Penicillin allergy: Avoid kits that contain amoxicillin.
- Pregnancy or breastfeeding: Clarithromycin needs particular caution, so your doctor may choose differently.
- Liver or kidney problems: Kit labels advise caution, so mention any liver or kidney condition before starting treatment.
- Heart rhythm problems: Clarithromycin can affect heart rhythm, so mention atrial fibrillation or an abnormal ECG.
- Diabetes: Clarithromycin with insulin or some diabetes tablets can cause low blood sugar, so check your blood sugar levels more closely.8
- Alcohol: Follow your product leaflet. Some kit leaflets advise avoiding alcohol, and this matters most with kits that contain tinidazole or metronidazole.
Why Treatment Sometimes Fails
The biggest reason is antibiotic resistance. The American College of Gastroenterology notes that resistance to clarithromycin has risen sharply, and older clarithromycin triple therapy clears only about 30% of infections when the bacteria are resistant.2 Its 2024 guideline now prefers a 14 day bismuth-based quadruple therapy, or newer options such as vonoprazan regimens, over the older triple kits when sensitivity is unknown.2 Missed doses and short courses add to the risk.
Testing After the Course
Feeling better does not prove the infection has gone, so guidelines advise a test of cure for everyone treated.2 A breath or stool test is usually done at least 4 weeks after the antibiotics end, and you may be asked to stop acid-reducing tablets for about 2 weeks before it, because they can hide the bacteria and give a false negative.7
Keep in Mind
Get urgent medical help for black or tarry stools, vomiting blood, severe stomach pain, or fainting, as these can mean a bleeding ulcer. Chest pain that feels like acidity can sometimes be a heart attack, so do not treat it at home.
Illustrative Scenario
Composite example, not a specific patient.
Arjun, 34, was prescribed a 14 day kit for a stomach ulcer. When the burning eased by day five, his pharmacist explained that bacteria can survive a short course. He finished all 14 strips, and his breath test six weeks later was negative.
Key Takeaways
- Check the salt names on your strip, because HP kits differ in what they contain.
- Follow the dosing schedule on your specific kit and prescription, and finish the full course.
- Tell your doctor about penicillin allergy, pregnancy, liver, heart or diabetes problems.
- Book a breath or stool test at least 4 weeks after finishing the course.
