Clinical Safety Experience with PREVACID I.V. (lansoprazole for injection) for Injection
More than 1,000 patients and subjects have participated in domestic and foreign clinical trials. Treatment with PREVACID I.V. (lansoprazole for injection) for Injection was well-tolerated.
In four U.S. trials involving 161 subjects exposed to PREVACID I.V. (lansoprazole for injection) for Injection, the following treatment-related adverse events were reported in ≥ 1% of subjects: headache (1.0%), injection site pain (1.0%), injection site reaction (1.0%) and nausea (1.3%). Treatment-related adverse events occurring in less than 1% of subjects included abdominal pain, vasodilatation, diarrhea, dyspepsia, vomiting, dizziness, paresthesia, rash, and taste perversion. No additional adverse drug reactions were reported with the intravenous formulation that had not been reported previously with the oral formulations.
Clinical Safety Experience with Oral Formulations of PREVACID
Worldwide, over 10,000 patients have been treated with oral 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.
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 in Table 4.

Adverse Events in
Short-Term, Placebo-Controlled PREVACID Studies

|Body as a Whole|
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 15 mg and 30 mg of PREVACID, but higher in the patients who received 60 mg of PREVACID (2.9%, 1.4%, 4.2%, and 7.4%, respectively).
Additional adverse experiences occurring in less than 1% of patients or subjects who received PREVACID in domestic trials are shown below:

Additional adverse experiences have been reported since oral PREVACID has been marketed. The majority of these cases are foreign-sourced and a relationship to PREVACID has not been established. Because these events were reported voluntarily from a population of unknown size, estimates of frequency cannot be made. These events are listed below by COSTART body system.
Body as a Whole -anaphylactic/anaphylactoid reactions; Digestive System - hepatotoxicity, pancreatitis, vomiting; Hemic and Lymphatic System - agranulocytosis, aplastic anemia, hemolytic anemia, leukopenia, neutropenia, pancytopenia, thrombocytopenia, and thrombotic thrombocytopenic purpura; Musculoskeletal System - myositis; Skin and Appendages - severe dermatologic reactions including erythema multiforme, Stevens-Johnson syndrome, toxic epidermal necrolysis (some fatal); Special Senses - speech disorder; Urogenital System - interstitial nephritis, urinary retention.
There were no clinically important changes identified in any laboratory parameter with PREVACID I.V. (lansoprazole for injection) for Injection.
The following changes in laboratory parameters in patients who received PREVACID were reported as adverse events:
Abnormal liver function tests, increased SGOT (AST), increased SGPT (ALT), increased creatinine, increased alkaline phosphatase, increased globulins, increased GGTP, increased/decreased/abnormal WBC, abnormal AG ratio, abnormal RBC, bilirubinemia, eosinophilia, hyperlipemia, increased/decreased electrolytes, increased/decreased cholesterol, increased glucocorticoids, increased LDH, increased/decreased/abnormal platelets, and increased gastrin levels. Urine abnormalities such as albuminuria, glycosuria, and hematuria were also reported. Additional isolated laboratory abnormalities were reported.
In the placebo controlled studies, when SGOT (AST) and SGPT (ALT) were evaluated, 0.4% (4/978) and 0.4% (11/2677) patients, who received placebo and PREVACID, respectively, had enzyme elevations greater than three times the upper limit of normal range at the final treatment visit. None of these patients who received PREVACID reported jaundice at any time during the study.
