Lansoprazole, Amoxicillin, Clarithromycin Side Effects

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

Table 8: Adverse Reactions Most Frequently Reported in Clinical Trials (≥3%) Adverse Reaction Triple Therapy 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.

Lansoprazole Delayed-Release Capsules The following adverse reactions from the labeling for lansoprazole delayed-release capsules are provided for information: Worldwide, over 10,000 patients have been treated with lansoprazole delayed-release capsules in Phase 2 or Phase 3 clinical trials involving various dosages and durations of treatment.

In general, lansoprazole delayed-release capsules 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 lansoprazole delayed-release capsules-treated patients and occurred at a greater rate in lansoprazole delayed-release capsules-treated patients than placebo-treated patients: Table 9: Incidence of Possibly or Probably Treatment-Related Adverse Reactions in Short-Term, Placebo-Controlled Lansoprazole Delayed-Release Capsules Studies Body System/Adverse Event Lansoprazole Delayed-Release Capsules (N=2768) % Placebo (N=1023) % Body as a Whole Abdominal Pain 2.1 1.2 Digestive System Constipation 1.0 0.4 Diarrhea 3.8 2.3 Nausea 1.3 1.2 Headache was also seen at greater than 1% incidence but was more common on placebo.

The incidence of diarrhea was similar between patients who received placebo and patients who received 30 mg of lansoprazole delayed-release capsules, but higher in the patients who received 60 mg of lansoprazole delayed-release capsules (2.9%, 4.2%, and 7.4%, respectively).

The most commonly reported possibly or probably treatment-related adverse event during maintenance therapy was diarrhea.

The majority of these cases are foreign-sourced and a relationship to lansoprazole delayed-release capsules has not been established.
