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.
