Prevpac (lansoprazole, amoxicillin and clarithromycin) is a combination of a proton pump inhibitor (PPI), a penicillin antibiotic, and a macrolide antibiotic used to prevent stomach ulcer caused by infection with Helicobacter pylori (H. pylori). Common side effects of Prevpac include:

  • diarrhea,
  • headache,
  • nausea,
  • vomiting,
  • stomach pain,
  • unusual or unpleasant taste in your mouth,
  • constipation,
  • dark colored stools,
  • dry mouth,
  • increased thirst, or
  • vaginal itching or discharge.

Tell your doctor if you have rare but very serious side effects of Prevpac including:

  • muscle weakness,
  • dark urine,
  • yellowing eyes or skin,
  • easy bruising or bleeding,
  • signs of infection (such as fever, persistent sore throat), or
  • mental/mood changes (such as agitation, confusion).

The recommended adult oral dose is 30 mg lansoprazole (Prevacid), 1 g amoxicillin, and 500 mg clarithromycin administered together twice daily (morning and evening) for 10 or 14 days. Prevpac may interact with HIV/AIDS medications, blood thinners, clopidogrel, cyclosporine, digoxin, iron supplements, fluconazole or ketoconazole, probenecid, rifabutin, sildenafil, tacrolimus, theophylline, sulfa drugs, cholesterol-lowering medicines, heart rhythm medications, sedatives, seizure medications, or tetracycline antibiotics. Tell your doctor all prescription and over-the-counter medications and supplements you use. During pregnancy, Prevpac should be used only when prescribed. Amoxicillin passes into breast milk. It is unknown if lansoprazole or clarithromycin pass into breast milk. Consult your doctor before breastfeeding.

Our Prevpac (lansoprazole, amoxicillin and clarithromycin) Side Effects Drug Center provides a comprehensive view of available drug information on the potential side effects when taking this medication.

A concise overview of the drug for the patient or caregiver from First DataBank.

Prevpac Overview - Patient Information: Side Effects

SIDE EFFECTS: Diarrhea, headache, nausea, vomiting, and abnormal taste may occur. If any of these effects persist or worsen, tell your doctor or pharmacist promptly.

Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.

Tell your doctor immediately if any of these rare but very serious side effects occur: muscle weakness, dark urine, yellowing eyes/skin, easy bruising/bleeding, signs of infection (such as fever, persistent sore throat), mental/mood changes (such as agitation, confusion).

Seek immediate medical attention if any of these rare but very serious side effects occur: severe dizziness, fainting, fast/irregular heartbeat.

This medication may rarely cause a severe intestinal condition (Clostridium difficile-associated diarrhea) due to a type of resistant bacteria. This condition may occur during treatment or weeks to months after treatment has stopped. Do not use anti-diarrhea products or narcotic pain medications if you have any of the following symptoms because these products may make them worse. Tell your doctor immediately if you develop: persistent diarrhea, abdominal or stomach pain/cramping, blood/mucus in your stool.

Use of this medication for prolonged or repeated periods may result in oral thrush or a new yeast infection. Contact your doctor if you notice white patches in your mouth, a change in vaginal discharge, or other new symptoms.

A very serious allergic reaction to this drug is rare. However, seek immediate medical attention if you notice any symptoms of a serious allergic reaction, including: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing, kidney problems (such as change in the amount of urine).

Amoxicillin can commonly cause a mild rash that is usually not serious. However, you may not be able to tell it apart from a rare rash that could be a sign of a severe allergic reaction. Therefore, seek immediate medical attention if you develop any rash.

This is not a complete list of possible side effects. If you notice other effects not listed above, contact your doctor or pharmacist.

(Adverse Reactions)

SIDE EFFECTS

PREVPAC

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice.

The most common adverse reactions (≥3%) reported in clinical trials when all three components of this therapy were given concomitantly for 14 days are listed in Table 6.

Table 6. Adverse Reactions Most Frequently Reported in Clinical Trials (≥3%)

  Triple Therapy
Adverse Reaction n=138
(%)
Diarrhea 7.0
Headache 6.0
Taste Perversion 5.0

The additional adverse reactions which were reported as possibly or probably related to treatment (less than 3%) in clinical trials when all three components of this therapy were given concomitantly are listed below and divided by body system:

Body as a Whole -abdominal pain

Digestive System -dark stools, dry mouth/thirst, glossitis, rectal itching, nausea, oral moniliasis, stomatitis, tongue discoloration, tongue disorder, vomiting

Musculoskeletal System-myalgia

Nervous System - confusion, dizziness

Respiratory System - respiratory disorders

Skin and Appendages -skin reactions

Urogenital System -vaginitis, vaginal moniliasis

There were no statistically significant differences in the frequency of reported adverse events between the 10-and 14-day triple therapy regimens.

PREVACID

The following adverse reactions from the labeling for PREVACID are provided for information:

Worldwide, over 10,000 patients have been treated with PREVACID in Phase 2 or Phase 3 clinical trials involving various dosages and durations of treatment. In general, PREVACID treatment has been well-tolerated in both short-term and long-term trials.

Incidence In Clinical Trials

The following adverse events were reported by the treating physician to have a possible or probable relationship to drug in 1% or more of PREVACID-treated patients and occurred at a greater rate in PREVACID-treated patients than placebo-treated patients:

Hemic and Lymphatic Systems – Anemia, including hemolytic anemia, thrombocytopenia, thrombocytopenic purpura, eosinophilia, leukopenia and agranulocytosis have been reported . These reactions are usually reversible on discontinuation of therapy and are believed to be hypersensitivity phenomena.

Central Nervous System – Reversible hyperactivity, agitation, anxiety, insomnia, confusion, behavioral changes, and/or dizziness have been reported.

Miscellaneous – Tooth discoloration (brown, yellow, or gray staining) has been reported. Most reports occurred in pediatric patients. Discoloration was reduced or eliminated with brushing or dental cleaning in most cases.
