What is Prevpac?
Prevpac is a prescription medication used to treat Helicobacter pylori (H. pylori) infections, a common cause of peptic ulcers and gastritis.
It combines three drugs: lansoprazole, a proton pump inhibitor (PPI) that reduces the amount of acid your stomach produces; amoxicillin, a penicillin antibiotic that prevents bacteria from forming protective cell walls; and clarithromycin, a macrolide antibiotic that blocks bacteria from making essential proteins needed for survival.
How Does Prevpac Work?
Prevpac combines three medications to treat H. pylori infections and stomach ulcers. The first ingredient, lansoprazole, is a proton pump inhibitor (PPI) that reduces stomach acid.
Lansoprazole helps heal ulcers and provides relief from pain by lowering acid levels. It blocks the proton pump, a part of the stomach cells responsible for producing acid.
The second component, amoxicillin, is a penicillin antibiotic that prevents H. pylori bacteria from building protective walls around themselves, stopping their growth and spreading.
The third ingredient, clarithromycin, is a macrolide antibiotic that interferes with the bacteria’s ability to produce proteins essential for survival, further eliminating the infection.
Prevpac Dosage Information and Usage
Adults usually take Prevpac as 30 mg of lansoprazole, 1 gram of amoxicillin, and 500 mg of clarithromycin, together twice daily – once in the morning and once in the evening for 10 to 14 days.
This combination effectively treats ulcer-causing bacteria and helps prevent their return.
People with severe kidney issues (creatinine clearance below 30 mL/min) should avoid using Prevpac.
Dosage Form and Strengths of Prevpac
Prevpac is available as a combination therapy in a 30 mg/1 gram/500 mg dose, containing:
- Lansoprazole 30 mg: A proton pump inhibitor to lower stomach acid.
- Amoxicillin 1 gram: An antibiotic to stop bacterial growth.
- Clarithromycin 500 mg: An antibiotic to eliminate bacteria by blocking protein synthesis.
How to Use Prevpac?
Take Prevpac precisely as your doctor has directed. In the morning and evening, swallow one lansoprazole capsule, two amoxicillin capsules, and one clarithromycin tablet with a glass of water.
To maximize effectiveness, follow a consistent schedule for 10 to 14 days.
Do not skip doses, and avoid taking two doses at once to make up for a missed dose.

Warnings and Precautions for Prevpac
Prevpac is a medication that requires careful consideration to ensure safe use.
Below are important warnings and precautions to keep in mind:
- If you are allergic to lansoprazole, amoxicillin, clarithromycin, or related medications like penicillin or cephalosporins, do not use Prevpac. Allergic reactions can include mild rashes or severe conditions such as anaphylaxis, which is a sudden and potentially life-threatening allergic response.
- Inform your doctor if you have liver or kidney problems. These conditions can affect how your body processes the medication, and adjustments to your dosage may be needed to prevent organ damage.
- Prevpac may interact with certain medications, such as cisapride or pimozide, leading to severe heart rhythm problems like QT prolongation, which is an irregular heart rhythm that can cause complications.
- The clarithromycin in Prevpac is not recommended during pregnancy because it may harm the fetus. If you are pregnant or planning to become pregnant, consult your doctor about safer alternatives.
- Using Prevpac may disrupt the natural balance of bacteria in your gut, increasing the risk of a condition called Clostridium difficile infection, which can cause severe diarrhea. Seek medical attention if you experience persistent or worsening diarrhea.
- Prolonged use of antibiotics in Prevpac may lead to superinfections caused by resistant bacteria or fungi.
- Combining Prevpac with certain drugs, such as ergotamine or some antihistamines like astemizole or terfenadine, can result in serious side effects, including breathing problems or heart complications.
- While Prevpac helps treat bacterial infections that cause ulcers, it does not eliminate the possibility of more serious conditions, such as gastric cancer.
- Severe kidney impairment may require adjusting the dosage of Prevpac to prevent harmful side effects.
Prevpac Drug Interactions With Other Medications
Lansoprazole, amoxicillin, and clarithromycin in Prevpac may interact with various medications, altering their effectiveness or causing side effects. To prevent harmful interactions, inform your doctor about your medications, supplements, or herbal products.
- Blood thinners (like Warfarin)
- HIV/AIDS medications (Atazanavir)
- Cholesterol-lowering medications (Simvastatin)
- Sedatives (Benzodiazepines)

Alternative Medications to Prevpac
If you are looking for alternatives to Prevpac, several options are available. Pylora is one option that combines three medications to treat Helicobacter pylori infections, similar to Prevpac.
Omeprazole, a proton pump inhibitor, is often used alongside antibiotics to help reduce stomach acid.
These alternatives may be suitable depending on your needs and your doctor’s advice.
