Side Effects (Adverse Reactions)
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 1. 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. Additional adverse experiences occurring in less than 1% of patients or subjects who received lansoprazole in domestic trials are shown below: Body as a Whole – abdomen enlarged, allergic reaction, asthenia, back pain, candidiasis, carcinoma, chest pain (not otherwise specified), chills, edema, fever, flu syndrome, halitosis, infection (not otherwise specified), malaise, neck pain, neck rigidity, pain, pelvic pain Cardiovascular System -angina, arrhythmia, bradycardia, cerebrovascular accident/ cerebral infarction, hypertension/hypotension, migraine, myocardial infarction, palpitations, shock (circulatory failure), syncope, tachycardia, vasodilation Digestive System – abnormal stools, anorexia, bezoar, cardiospasm, cholelithiasis, colitis, dry mouth, dyspepsia, dysphagia, enteritis, eructation, esophageal stenosis, esophageal ulcer, esophagitis, fecal discoloration, flatulence, gastric nodules/fundic gland polyps, gastritis, gastroenteritis, gastrointestinal anomaly, gastrointestinal disorder, gastrointestinal hemorrhage, glossitis, gum hemorrhage,...
Drug Interactions
Tables 2 and 3 include drugs with clinically important drug interactions and interaction with diagnostics when administered concomitantly with lansoprazole delayed-release capsules and instructions for preventing or managing them. Consult the labeling of concomitantly used drugs to obtain further information about interactions with PPIs. Table 2. Clinically Relevant Interactions Affecting Drugs Co-Administered with Lansoprazole Delayed-Release Capsules and Interactions with Diagnostics Antiretrovirals Clinical Impact: The effect of PPIs on antiretroviral drugs is variable. The clinical importance and the mechanisms behind these interactions are not always known. Decreased exposure of some antiretroviral drugs (e.g., rilpivirine, atazanavir, and nelfinavir) when used concomitantly with lansoprazole may reduce antiviral effect and promote the development of drug resistance. Increased exposure of other antiretroviral drugs (e.g., saquinavir) when used concomitantly with lansoprazole may increase toxicity of the antiretroviral drugs. There are other antiretroviral drugs which do not result in clinically relevant interactions with lansoprazole. Intervention: Rilpivirine-containing products: Concomitant use with lansoprazole is contraindicated [see Contraindications (4)] . See prescribing information. Atazanavir : See prescribing information for atazanavir for dosing information. Nelfinavir: Avoid concomitant use with Lansoprazole. See prescribing information for nelfinavir. Saquinavir: See the prescribing information for saquinavir and monitor for potential saquinavir toxicities. Other antiretrovirals : See prescribing information. Warfarin Clinical Impact: Increased INR and prothrombin time in patients receiving PPIs and warfarin concomitantly. Increases in INR and prothrombin time may lead to abnormal bleeding and even death. Intervention: Monitor INR and prothrombin time. Dose adjustment of warfarin may be needed to maintain target INR range. See prescribing information for warfarin. Methotrexate Clinical Impact: Concomitant use of PPIs with methotrexate (primarily at high dose) may elevate and prolong serum concentrations of methotrexate and/or its metabolite hydroxymethotrexate, possibly leading to methotrexate toxicities. No formal drug interaction studies of high-dose methotrexate with PPIs have been conducted [see Warnings and Precautions (5.10)] . Intervention: A temporary withdrawal of lansoprazole may be considered in some patients receiving high-dose methotrexate. Digoxin Clinical Impact: Potential for increased exposure of digoxin. Intervention: Monitor digoxin concentrations. Dose adjustment of digoxin may be needed to maintain therapeutic drug concentrations. See prescribing information for digoxin. Theophylline Clinical Impact: Increased clearance of theophylline [see Clinical Pharmacology (12.3)] . Intervention: Individual patients may require additional titration of their theophylline dosage when lansoprazole is started or stopped...
Contraindications
Lansoprazole is contraindicated in patients with known hypersensitivity to any component of the formulation. Hypersensitivity reactions may include anaphylaxis, anaphylactic shock, angioedema, bronchospasm, acute tubulointerstitial nephritis, and urticaria [see Warnings and Precautions (5.2), Adverse Reactions (6)]. Proton Pump Inhibitors (PPIs), including lansoprazole, are contraindicated with rilpivirine-containing products [see Drug Interactions (7)]. For information about contraindications of antibacterial agents (clarithromycin and amoxicillin) indicated in combination with lansoprazole, refer to the Contraindications section of their prescribing information.
Overdosage
Lansoprazole is not removed from the circulation by hemodialysis. In one reported overdose, a patient consumed 600 mg of lansoprazole with no adverse reaction. Oral lansoprazole doses up to 5000 mg/kg in rats [approximately 1300 times the 30 mg human dose based on body surface area (BSA)] and in mice (about 675.7 times the 30 mg human dose based on BSA) did not produce deaths or any clinical signs. In the event of over-exposure, treatment should be symptomatic and supportive. If over-exposure occurs, call your poison control center at 1-800-222-1222 for current information on the management of poisoning or over-exposure.
