General

The most frequently reported adverse events include abdominal pain, diarrhea, and flatulence.[Ref]

Gastrointestinal

Very common (10% or more): Abdominal pain (19%), diarrhea (31%), flatulence (74%)
Uncommon (0.1% to 1%): Nausea,, vomiting, dyspepsia
Postmarketing reports: Ileus/subileus, pneumatosis cystoides intestinalis[Ref]

In large-scale clinical trials, a majority of patients have complained of gastrointestinal (GI) side effects. GI side effects usually developed within the first few weeks of therapy, were usually mild to moderate in severity, and typically decreased over time. The most common GI side effects were due to the fermentation of unabsorbed carbohydrates and resultant gas production. The severity of GI symptoms may be decreased by dosage reduction and by avoidance of gas-producing foods and sucrose.

There have been rare postmarketing reports of pneumatosis cystoides intestinalis associated with alpha-glucosidase inhibitors including this drug. If suspected, discontinue therapy and perform appropriate diagnostic testing.[Ref]

Hepatic

Very common (10% or more): Serum transaminase elevations (14%)
Postmarketing reports: Fulminant hepatitis with fatal outcome, jaundice and/or hepatitis and associated liver damage[Ref]

Treatment-emergent elevations of AST and ALT to greater the upper limit of normal, greater than 1.8 x ULN) and greater than 3 x ULN have been observed in 14%, 6%, and 3% of patients in studies of up to 12 months with doses up to 300 mg 3 times a day. The elevations were more common in women and generally asymptomatic and reversible. Additionally, these elevations appear to be dose-related.

International postmarketing experience: There have been 62 reports of of serum transaminase elevations to greater than 500 international units/liter, 29 were associated with jaundice.
