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 practice.
The safety of DEXILANT was evaluated in 4548 patients in controlled and uncontrolled clinical studies, including 863 patients treated for at least 6 months and 203 patients treated for one year. Patients ranged in age from 18 to 90 years (median age 48 years), with 54% female, 85% Caucasian, 8% Black, 4% Asian, and 3% other races. Six randomized controlled clinical trials were conducted for the treatment of EE, maintenance of healed EE, and symptomatic GERD, which included 896 patients on placebo, 455 patients on DEXILANT 30 mg, 2218 patients on DEXILANT 60 mg, and 1363 patients on lansoprazole 30 mg once daily.
Most Commonly Reported Adverse Reactions: The most common adverse reactions (≥2%) that occurred at a higher incidence for DEXILANT than placebo in the controlled studies are presented in Table 10. (See Table 10.)

Adverse Reactions Resulting in Discontinuation: In controlled clinical studies, the most common adverse reaction leading to discontinuation from DEXILANT therapy was diarrhea (0.7%).

Additional adverse reactions that were reported in a long-term uncontrolled study and were considered related to DEXILANT by the treating physician included: anaphylaxis, auditory hallucination, B-cell lymphoma, bursitis, central obesity, cholecystitis acute, dehydration, diabetes mellitus, dysphonia, epistaxis, folliculitis, gout, herpes zoster, hyperlipidemia, hypothyroidism, increased neutrophils, MCHC decrease, neutropenia, rectal tenesmus, restless legs syndrome, somnolence, tonsillitis. Other adverse reactions not observed with DEXILANT, but occurring with the racemate lansoprazole can be found in the lansoprazole prescribing information.
Pediatrics: The safety of DEXILANT capsules were evaluated in controlled and single-arm clinical trials including 104 pediatric patients,12 to 17 years of age for the relief of heartburn [see Pharmacology: Pharmacodynamics: Clinical Studies under Actions].
The adverse reaction profile was similar to that of adults. The most common adverse reactions that occurred in ≥5% of patients were diarrhea, headache and abdominal pain.
Post-marketing Experience: The following adverse reactions have been identified during post-approval of DEXILANT. As these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.
Blood and Lymphatic System Disorders: autoimmune hemolytic anemia, idiopathic thrombocytopenic purpura.
Ear and Labyrinth Disorders: deafness.
Eye Disorders: blurred vision.
Gastrointestinal Disorders: oral edema, pancreatitis, microscopic colitis.

Skin and Subcutaneous Tissue Disorders: generalized rash, leucocytoclastic vasculitis, Stevens-Johnson Syndrome, DRESS and Toxic Epidermal Necrolysis (some fatal), subacute cutaneous lupus erythematosus.
≠ hypocalcemia and/ or hypokalemia may be related to the occurrence of hypomagnesemia (see Precautions).
