Lansoprazole, Amoxicillin, Clarithromycin

INDICATIONS AND USAGE H. pylori Eradication to Reduce the Risk of Duodenal Ulcer Recurrence The components in lansoprazole delayed-release capsules, amoxicillin capsules, and clarithromycin tablets are indicated for the treatment of patients with H. pylori infection and duodenal ulcer disease (active or one-year history of a duodenal ulcer) to eradicate H. pylori . Eradication of H. pylori has been shown to reduce the risk of duodenal ulcer recurrence (see CLINICAL STUDIES and DOSAGE AND ADMINISTRATION ).

ADVERSE REACTIONS LANSOPRAZOLE DELAYED-RELEASE CAPSULES, AMOXICILLIN CAPSULES, AND CLARITHROMYCIN TABLETS 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 8.

Pregnancy Teratogenic Effects Pregnancy Category C Category C is based on the pregnancy category for clarithromycin. There are no adequate and well-controlled studies of lansoprazole, clarithromycin or amoxicillin (used separately or together) in pregnant women. Lansoprazole delayed-release capsules, amoxicillin capsules, and clarithromycin tablets should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus and there is no appropriate alternative therapy (see WARNINGS ).

WARNINGS Acute Hypersensitivity Reactions Serious and occasionally fatal hypersensitivity (anaphylactic) reactions have been reported in patients on penicillin therapy, including amoxicillin. Although anaphylaxis is more frequent following parenteral therapy, it has occurred in patients on oral penicillins. These reactions are more likely to occur in individuals with a history of penicillin hypersensitivity and/or a history of sensitivity to multiple allergens. There have been reports of individuals with a history of penicillin hypersensitivity who have experienced severe reactions when treated with cephalosporins. CONTRAINDICATIONS Lansoprazole delayed-release capsules, amoxicillin capsules, and clarithromycin tablets are contraindicated in patients with known severe hypersensitivity to any component of the formulation of lansoprazole delayed-release capsules.
