Side Effects by Body System

Gastrointestinal

Gastrointestinal side effects occur in the majority of patients. In one study, up to 68% of patients complained of gastrointestinal side effects. Constipation is most common and can be severe. Intestinal obstruction is reported with another bile acid sequestrant; elderly and pediatric patients treated with colestipol may be at risk for this as well. Increases in fluid intake as well as dietary fiber may help to reduce the severity of constipation. In general, gastrointestinal side effects tend to diminish with continued therapy. If gastrointestinal side effects are significant, dosage reduction, even if temporary, may be beneficial.

Gastrointestinal side effects include constipation (10 to 28%), heartburn (17%), abdominal discomfort (11%), nausea (9%), belching, flatulence, vomiting, and diarrhea. Peptic ulceration, gastrointestinal irritation and bleeding, cholecystitis, cholelithiasis, and anorexia have been reported rarely.
