Lansoprazole Dr Side Effects

The following serious adverse reactions are described below and elsewhere in labeling: Acute Tubulointerstitial Nephritis [see Warnings and Precautions ( 5.2)] Clostridium difficile-Associated Diarrhea [see Warnings and Precautions ( 5.3)] Bone Fracture [see Warnings and Precautions ( 5.4)] Severe Cutaneous Adverse Reactions [see Warnings and Precautions (5.5)] Cutaneous and Systemic Lupus Erythematosus [see Warnings and Precautions (5.6)] Cyanocobalamin (Vitamin B 12) Deficiency [see Warnings and Precautions (5.7)] Hypomagnesemia and Mineral Metabolism [see Warnings and Precautions (5.8)] Fundic Gland Polyps [see Warnings and Precautions (5.12)] 6.1 Clinical Trials Experience 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.

Worldwide, over 10,000 patients have been treated with lansoprazole in Phase 2 or Phase 3 clinical trials involving various dosages and durations of treatment.

In general, lansoprazole treatment has been well-tolerated in both short-term and long-term trials.

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

Table 1: Incidence of Possibly or Probably Treatment-Related Adverse Reactions in Short-Term, Placebo-Controlled Lansoprazole Studies Body System/Adverse Reaction Lansoprazole (N= 2768) % Placebo (N= 1023) % Body as a Whole Abdominal Pain 2.1 1.2 Digestive System Constipation Diarrhea Nausea 1.0 3.8 1.3 0.4 2.3 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 15 mg and 30 mg of lansoprazole, but higher in the patients who received 60 mg of lansoprazole (2.9%, 1.4%, 4.2%, and 7.4%, respectively).

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

In the risk reduction study of lansoprazole for NSAID-associated gastric ulcers, the incidence of diarrhea for patients treated with lansoprazole, misoprostol, and placebo was 5, 22,and 3%, respectively.

Another study for the same indication, where patients took either a COX-2 inhibitor or lansoprazole and naproxen, demonstrated that the safety profile was similar to the prior study.

Additional reactions from this study not previously observed in other clinical trials with lansoprazole included contusion, duodenitis, epigastric discomfort, esophageal disorder, fatigue, hunger, hiatal hernia, hoarseness, impaired gastric emptying, metaplasia, and renal impairment.
